When in the MENU used to navigate or alter selected configuration items.
TReX User Manual v2.14 Firmware Main Screens The TReX top icon bar provides information about the display screen and operating status. .The far right text indicates the selected main screen. This is either “IO” (inputs and outputs), “TX” (transmit) or “RX” (receive). The far left icon indicates system voltage as a proportion of the configured high and low battery levels (MENU->INPUTS->BATT HIGH/LOW V). The “X” icon is visible when no messages have been received for 2 minutes and on start-up.
TReX User Manual v2.14 Firmware IO Screens Screens that relate to inputs and outputs. IO (1): All input and output states. Each IO highlighted state changes if the IO level is HIGH or LOW. There is a small line above each input or output if HIGH, and a line below if LOW. All ADCs (analog inputs) and DACs (analog outputs) show a bar graph as a proportion of full scale and display a raw count from 0-1023. When scaling has been applied to an analog output, the DAC value shown is the unscaled value.
TReX User Manual v2.14 Firmware IO (2): System voltage, current and internal operating temperature. RF is the temperature read directly next to the RF power stage and will be higher than than the DIG board temperature while the TReX is transmitting (not applicable for receiver only TReX units). Temperatures of the RF power stage may reach 100 degrees Celsius under normal long term operation. These temperatures are not the ambient temperature. The case of the TReX will NOT reach these temperatures.
TReX User Manual v2.14 Firmware TX Screens Screens that relate to messages transmitted. TX (1): Last message transmitted. Includes the time the message was transmitted, message RIC (radio identifying code/CAP Code) and level (0-3). To the right the modulation type and rate is displayed also with the transmit frequency. TX (2): List of all time-stamped messages retrieved from internal storage. Most recent message displayed at top. Next sub-screen can only be selected when top entry is displayed.
TReX User Manual v2.14 Firmware TX (3): Displays the last transmitted message in large font. If the message exceeds the screen size, the DOWN button allows scrolling. TX (4): A TX power bar graph is displayed as a proportion of full power during a message transmission. Above the power bar is the text “POWER – 2W (168)”. “2W” relates to the power setting in use. In brackets is the power amplifier DAC setting which is for factory use only. The POWER ADC count is used to indicate forward power.
TReX User Manual v2.14 Firmware RX Screens Screens that relate to messages received. Note, when messages are received, additional icons may be displayed in the top bar. The second left icon changes from the “X” icon to the satellite icon when a message has been received. This indicates that the receiver is operational. When the “BELL” icon is displayed with a following number, this means that system ALERTS are enabled. See ALERTS for ALERT configuration and operation.

ALERT Visual notification and repeating beep (at a configurable interval) when a message is received that meets the conditions for raising an alert. See ALERT FILTER. If the ALERT output is enabled the configured output will also operate. Can be configured from 0-250 seconds.
TReX User Manual v2.14 Firmware control characters within the key words used and each matching phrase must be on a new line. ALERT FILTER This filter option allows the use of a text file called “ALERT.TXT” to be stored and modified on the SD card (accessible via the USB port). If the feature is enabled (ALERT set to value), this file (if present) will be searched for key words.
TReX User Manual v2.14 Firmware contents: FIRE EMERGENCY All messages WITHOUT these key words WILL BE DISCARDED. Even though non matching messages are discarded, the receiver OK indicators and timers will continue to operate normally. INCL FILT set to DISABLED: Messages are not filtered INCL FILT set to ENABLED: Messages are filtered EXCL FILTER This filter option allows the use of a text file called “EXCL.TXT” to be stored and modified on the SD card (accessible via the USB port).
TReX User Manual v2.14 Firmware Protocol Menu TX Specifies the protocol to apply for serial input. Accepts WTE, CUSTOM, RAW, AUX and in some cases others as required or specified. RX Specifies the protocol to apply for serial output. Accepts WTE, CUSTOM, RAW, AUX and in some cases others as required or specified. SENT RESP This the response out the serial port at the completion of each transmitted message. By default this is “Page Sent”. Note: The default overriding response for WT protocol is “WT[xxx]”.
TReX User Manual v2.14 Firmware TCP-IP Menu TCP-IP The TCP-IP configuration lets you choose the TCP protocol for use on the TReX. WEB: This setting allows the TReX to be monitored and configured from a Chrome web browser either on a PC or mobile device. SERVER: This setting allows the TReX to be operated as a TCP server on the specified TCP port. SERVER would typically be used if a short term connection was required, such as to change a configuration item or send a message for transmitting.
TReX User Manual v2.14 Firmware Concurrent WEB and CLIENT functionality. DISABLED: Setting to DISABLED ensures the maximum possible power savings even when an Ethernet cable has been connected. When IP is DISABLED, current consumption will reduce by approximately 150mA and disable the TCP stack. HOST This is the name that can be associated to the TReX. This name can be used directly instead of the IP address to address the TReX. By default is “WTE-TReX” ADDR IP Address for access to the TReX.
TReX User Manual v2.14 Firmware Telemetry Menu MODE DISABLED: there are no autonomous transmissions. SERIAL LINK: Serial arriving on an enabled serial port is sent to a remote TReX unit. IO MIRROR: All local unit enabled inputs are mirrored to outputs of a remote device based on the IO MIRROR configuration. IO_MIRROR can only support 2 TReX units. SCADA monitoring and controlling is not possible in this MODE.
TReX User Manual v2.14 Firmware This is the ID of the remote device that all inputs will be sent to. When the MODE is configured to be SCADA_MASTER this is the ID of the first SCADA_SLAVE TReX. All SCADA_SLAVES must be consecutively numbered following this ID. When the MODE SCADA_SLAVE is used, the REMOTE_ID is configured to be the same as the LOCAL_ID (this is required by the SCADA_MASTER to identify the source of the transmission). REMOTES This parameter is only used when the MODE is SCADA_MASTER.
TReX User Manual v2.14 Firmware SERIAL LINK Menu This a duplication to settings used by the RAW protocol. These settings allow the transmission to be optimised. TX TIMEOUT This is the period of serial port inactivity in 10mS steps that the TReX will wait before transmitting. In this case, placing a small delay between characters will result in poor transmission efficiency. TX LEN This configures how many characters must be buffered before transmission.
TReX User Manual v2.14 Firmware STORE FWD Menu OPERATION When store forward operation ENABLED the unit is used to listen to transmissions in the area, decode the messages and retransmit again to provide greater coverage than would normally be possible. When DISABLED there is no store and forward function. The non zero value set is the delay in 100ms steps after each transmission. This delay allows time for any downstream forwarding equipment to clear the message.
TReX User Manual v2.14 Firmware Inputs Menu 1-8 Configuration of messages that are transmitted when an input changes. Receiver only TReX units instead of transmitting can directly send WT protocol messages via serial ports or a TCP connection. BATT Treated as the 9th input. Messages transmitted when system voltage is high or low (high and low levels configurable). ADC 1-2 Treated as Inputs 10 and 11. Messages transmitted when ADC levels are above or below set thresholds.
TReX User Manual v2.14 Firmware ADC CAL Sub-Menu When the analog inputs are being read, scaling can be applied that allows the user to specify an INPUT from 0-1023 over a useful range from MIN to MAX. For example, if MIN is 200 and MAX is 400, then any analog INPUT below 200 will be SCALED to 0. Any INPUT above 400 will be SCALED to 1023. An INPUT of 300 will return a SCALED value of 512. This is useful if a small voltage range is of interest, such as 1-5V instead of 0-10V.
TReX User Manual v2.14 Firmware Calibration Procedure for Voltage Inputs: 1. Connect a voltage source (with an input resistance not more than 2 k ohm). 2. Set the voltage source to the minimum voltage that will be used. 3. Set ADC CAL->MIN to the value shown in the INPUT field. 4. Set the voltage source to the maximum voltage that will be used (up to 16V). 5. Set ADC CAL->MAX to the value shown in the INPUT field. 6. Check that when the minimum voltage is connected, the SCALED field displays close to 0. 7.
TReX User Manual v2.14 Firmware Input Config Sub-Menu These input configuration screens repeat for each of the 8 inputs plus the BATT and ADC inputs. INIT STATE Input messages are transmitted when the input changes from one state to another. On start-up the first transmitted message depends on this configuration. UNSET will ensure that there is never a transmission on start, whereas the HIGH or LOW states assume a certain start condition, so that an immediate transmission on start is possible.
TReX User Manual v2.14 Firmware TX COUNT LOW If set to 0, then there will there will be NO transmissions when moving to the LOW state. If non-zero then this is the number of times the LOW message will be transmitted. If there is a change of state again, then any remaining transmissions are cancelled. When set to a non-zero TX COUNT, the input level is considered to be ENABLED, and displayed as ENABLED on the upper menu level.
TReX User Manual v2.14 Firmware Note: The BATT input threshold settings are also used to set the battery icon on the main screens. MSG HI The message that is transmitted (formatted for the selected protocol) when the input moves to the HIGH level. Input messages must always use WT Protocol.
TReX User Manual v2.14 Firmware Outputs Menu 1-8 The output to configure. If the output has been configured for general output control through telemetry or messaging the output must be configured to LATCHED or MSHOT. In order to set to LATCHED or MSHOT the output mode must be set to TELEMETRY in the Output Config Sub-Menu. If the output has already been assigned for a special output function, the function will be displayed against the output e.g. RF ERROR.
TReX User Manual v2.14 Firmware DAC CAL Configures calibration of analog output 1 and 2. See DAC CAL Sub-Menu. ALERT When DISABLED there is no output change when an ALERT condition is met. When set to 18 this is the output that will operate when an ALERT is signalled. BUSY When DISABLED there is no output change when receive channel is BUSY. When set to 1-8 this is the output that will be high when the signal strength on the channel exceeds the RX BUSY LEVEL.
TReX User Manual v2.14 Firmware Output Config Sub-Menu MODE When set to TELEMETRY the output can be controlled through TELEMETRY settings or through output control messages that may be received. Setting to TELEMETRY will show the output to be configured to either LATCHED or MSHOT depending on the MSHOT setting. On start outputs are ALWAYS LOW. After the expiration of any MONOSHOT period for an output, the OUTPUT will return to the LOW state.
TReX User Manual v2.14 Firmware DAC CAL Sub-Menu Analog outputs can be configured to operate as constant voltage or constant current. This makes the outputs suitable for outputs such as 0-10V or 4-20mA. The analog output is current limited internally at approx 35mA. DAC Output impedance is 5 ohms. In VOLTAGE mode: Ensure that the wiring SERIES impedance is as low as possible. There will be a voltage drop across any series resistance that will affect the output voltage.
TReX User Manual v2.14 Firmware MAX OUTPUT values. Regardless of the MIN and MAX settings, the full control range of 01023 can be used. This is a test parameter only, useful for calibration. This is the value that the user would send to the TReX in order to control the outputs. OUTPUT This is a read only field showing the current flowing and unscaled raw output. This value will sit between MIN and MAX. MODE Sets either constant VOLTAGE or CURRENT mode.
TReX User Manual v2.14 Firmware Serial Command Configuration Most items that can be changed via the MENU can also be changed through serial commands. There are some additional commands that make the TReX more usable when being managed via a serial connection. These are listed immediately below. These commands must begin with the character ‘*’ and are processed with a carriage return character. Any characters before the ‘*’ may result in the command not being processed.
TReX User Manual v2.14 Firmware *RSSI Returns the receiver signal strength in -dBm. (returns between 0 and -130). Usage: *RSSI *USERPASS Sets the web and TCP user and password. User must be at least 3 letters and password must be at least 4 letters. These credentials are requested for each new web and TCP connection. Typical usage: *USERPASS=admin:TReX When prompted for a login when using a TCP connection (not through web browser), login with the full user and password together. e.g.
TReX User Manual v2.14 Firmware *TEMP Returns temperature of first the digital board, then the RF temperature sensor. This is NOT the ambient temperature. Temperatures in excess of 100 degrees C are completely normal under typical transmitting operation. Usage: *TEMP Typical output: TEMP=DIG:55.0C RF:60.1C *PWR Returns current forward power ADC count and system current both at the time of reading and recorded during the last transmission. Usage: *PWR Typical output: PWR=0,34,0.28,1.
TReX User Manual v2.14 Firmware NNNNNNN are 7 digits specifying the RIC code to be used for the message : is the character ‘:’ L is beep level for the message to be processed from 0-3. ] is the character ‘]’ MMMMMM is the payload of the message to be processed. Typical Usage 1: *BYPASS=[1234567:1]Test Message “Test Message” will be added to the RX message screens, logged etc, as if received across the air.
TReX User Manual v2.14 Firmware Transmit Commands *TX_FREQ Specifies the transmit frequency in Hz e.g. *TX_FREQ=160000000 *TX_PROTO Specifies the protocol to apply for serial input. Accepts WTE, CUSTOM, RAW and AUX. Typical usage: *TX_PROTO=WTE Note: See protocol section for more details on protocols and configuration. *TX_BAUD Specifies the baud rate of the transmitter when using a protocol that does not permit a baud rate to be specified.
TReX User Manual v2.14 Firmware *TX_LEVEL Specifies the default level of messages transmitted. This is sometimes referred to as “Beep Level”. This is a value 0-9, however, when POCSAG is the transport method, only 0-3 will be used. Typical usage: *TX_LEVEL=3 *TX_CAP Specifies the default code used to identify transmissions (same as the RIC code). The TX_CAP code would only be used by protocols that do not require the CAP code to be specified.
TReX User Manual v2.14 Firmware power when the receivers is in deep sleep mode. The POCSAG standard uses a setting of 18 (576 bits – configured in steps of 32). This very long preamble means that paging receivers need only to wake briefly once per second (at 512 baud) in order to check for an incoming message. If the receiver is always powered and receiving, then much shorter preambles can be used, and in some cases halve the channel activity.
TReX User Manual v2.14 Firmware Receive Commands *RX_ENABLE Allows the receiver to be disabled to save power if required. Typical usage: *RX_ENABLE=1 *RX_FREQ Specifies the receive frequency in Hz (range limited to the variant of product). Typical usage: *RX_FREQ=160000000 *RX_BAUD Specifies the baud rate of the receiver.
TReX User Manual v2.14 Firmware *RX_MODE=POCSAG_A *RX_RANGE Specifies up to 8 CAP RX ranges for decoding. Messages received with CAP codes not within the RX_RANGE will be discarded by the receiver. CAP codes should not fall within multiple ranges. If an output has been configured to operate on a range match, a second output configured for another range with the same CAP code will not operate.
TReX User Manual v2.14 Firmware Store Forward Commands Store forward operation is when the unit is used to listen to transmissions in the area, decode the messages and retransmit again to provide greater coverage than would normally be possible. Note: In order to forward messages the decoded message CAP codes must fall within the configured CAP ranges.
TReX User Manual v2.14 Firmware Input Commands The input commands allow messages to be configured for transmission when changing state. Debouncing (how long an input is settled before acting on the new level) can be configured with the number of times to transmit the input message. Note: Even if an input is configured to transmit a certain number of messages, should the input level change before all messages are transmitted, then the remaining transmissions will be cancelled.
TReX User Manual v2.14 Firmware Where: I = The input to configure (1-11 valid). Input 9 is the VIN input, 10 is ADC 1 and 11 is ADC 2. : = the colon character ‘:’ N = number of transmissions (0 = no transmissions, 9 is max transmission count) , = the comma character ‘,’ D = debounce in 100 ms steps (from 0-255) , = the comma character ‘,’ R = time in seconds between retransmissions.

TReX User Manual v2.14 Firmware response to “Page Sent” a leading ‘*’ character must be used in the PROTOCOL->SENT RESP config item. e.g. “*Page Sent”. Received Messages All messages received come out via the serial port as configured in by the *RX_PROTO setting: If *RX_PROTO=WTE then the output will look like: WT1234567A10TEST The exact same format allows units to be connected together, or protocols to be converted from one type to another.
TReX User Manual v2.14 Firmware Variable Content Macros WT Protocol can use several macro tags to display variable content. This may be useful as part of a periodic message for example to report battery voltage or IO conditions. Any number of macros can be used in any location of the message until the max message length has been reached.
TReX User Manual v2.14 Firmware Modbus The TReX supports both RTU and TCP modbus protocol options. These are well established and defined protocols used primarily in SCADA control and monitoring applications. These Modbus protocols can be used over any of the RS232, RS422, RS485 and Ethernet interfaces. Baud-rates, IP configuration and Modbus specific configuration items are through: MENU->PROTOCOL->MODBUS. This is an optional feature. Note that the Modbus TCP protocol by default uses port 502.

TReX User Manual v2.14 Firmware Custom Protocol This protocol allows many existing protocols provided by other vendors to be supported by the parsing of fields based on configuration (without new firmware being required). The custom protocol takes as a starting point various default values that may or may not be replaced depending on how the unit is configured: - Preconfigured default cap code (*TX_CAP=1234567). - Preconfigured default level or priority (*TX_LEVEL=0).
TReX User Manual v2.14 Firmware CAP - the field is parsed into the cap code to use (match string ignored). LEVEL - the field is parsed into the priority of beep level (match string ignored). MSG - the field is parsed into the message field (match string ignored). BAUD_512 - the field is parsed and if matches 512 baud is set for outgoing message. BAUD_1200 - the field is parsed and if matches 1200 baud is set for outgoing message.
TReX User Manual v2.14 Firmware *CUST_FIELD=5:12,0,””,,MSG To make more robust, further checks on the input can be made in this case to look for ‘-’ characters (at index 9 and 11): • Set match field 6, start at index 9 for a length of 1 character. If the “-” string is not matched, the entire message will be considered invalid and discarded. *CUST_FIELD=6:9,1,”-”,,MATCH • Set match field 7, start at index 11 for a length of 1 character.
TReX User Manual v2.14 Firmware Custom Protocol Response This section defines the serial output from the TReX back to the user when a message has been accepted for transmission. Responds with up to 3 custom response fields followed by a Supported attributes are: CONST (includes in the response exactly the content configured between “”). CAP (includes the CAP code of the transmitted message in the response). LEVEL(includes the beep level of the transmitted message in the response).
TReX User Manual v2.14 Firmware *CUST_OUTPUT *CUST_OUTPUT is the start point to construct the serial output message. This command holds constant text that may then be modified by the CUST_FIELDS commands if required. For example, when an over the air message is received the serial output may need to be forwarded to another providers’ equipment. Imagine that the required output to drive this equipment is “AABBCCCCMMM”.
TReX User Manual v2.14 Firmware RAW Protocol The Raw protocol uses all default settings to determine the data rate, transport method, cap code etc. This protocol is the protocol used when using a point to point serial link.
TReX User Manual v2.14 Firmware the length can still be sent, but there will be a small delay between each transmission. Transmission delays may be longer than expected if the TReX determines that the channel is busy. Parameter 3 specifies a character that results in immediate transmission (0 if unused).
TReX User Manual v2.14 Firmware SCADA Support SCADA (Supervisory Control And Data Acquisition) is a term used widely in many industries relating to monitoring and control systems. This section deals with the integration of the TReX into a SCADA system. This is an optional feature, that requires a feature key to be purchased. Terminology SCADA application: This is a software package that is used to control and monitor devices. This could be free open source packages such as “Rapid SCADA” or “openSCADA”.
TReX User Manual v2.14 Firmware Working Example As a simple working example shown below, web content is being served to a PC and mobile devices using the open source application “RapidSCADA”. SCADA applications have the advantages to provide a means to notify through; email, paging messages, SMS or to generate alarms of critical system events.
TReX User Manual v2.14 Firmware SCADA System Single TReX Configuration This is a system that requires no expansion through use of SLAVE units.
TReX User Manual v2.14 Firmware Unit Configuration Since this system configuration is only for a single TReX unit, the LOCAL ID and REMOTE ID fields are not used and can be set to anything. The MODBUS ID can be any value from 0127 (except 42 or 87). MENU->PROTOCOL->MODBUS is used to configure the key SCADA parameters, such as unit ID and the protocol. Typically, if an Ethernet connection is used, the TCP protocol will be used. See MODBUS Protocol for more Modbus information.
TReX User Manual v2.14 Firmware SCADA System Multiple TReX Configuration Up to 10 wireless SLAVES can be controlled by a MASTER. A SCADA application will be able to monitor and control all TReX IO on the MASTER and SLAVE TReX units. Simple Example A remote station controlling two separate pump stations, where the “Remote Station” has a TReX units connected to a SCADA system and the “Pump Stations” may have several pumps and other I/O devices connected.
TReX User Manual v2.14 Firmware Units Configuration “Remote Station” Configuration The LOCAL ID must be configured to a system unique value (default “01”). REMOTE ID must be configured to the ID of the first SLAVE LOCAL ID. MODBUS ID can be any value from 0-127 (except 42 or 87).
TReX User Manual v2.14 Firmware “Pump Station 1” Configuration “Pump Station 2” Configuration The MASTER unit has configured REMOTES to a value of 2 (meaning there are 2 SLAVE units). Note that each SLAVE must start at the REMOTE ID configured on the MASTER, and each SLAVE in the system must be consecutively numbered. The SLAVE configuration is unique in that both the LOCAL ID and REMOTE ID need to be the same.
TReX User Manual v2.14 Firmware Viewing Multiple TReX Unit IO on the MASTER Unit. The MASTER on the IO screens can view all system inputs and outputs without the need for a SCADA application. This is useful for debugging and installation. Shown in this case is the number “01”, followed by “069”, where“01” in this case is the UNIT ID in the system. The “069” is a “link fail” counter used to determine loss of communication for a unit. This number is reset whenever a new message is decoded from a SLAVE unit.
TReX User Manual v2.14 Firmware SCADA Communication Between MASTER and SLAVE All communication between the MASTER and SLAVE units can be viewed on the RX and TX screens. These messages are of little application to the user, and documented here purely for clarity of function and debugging if required. These messages are a variation of the WTE Output Control Protocol. There are however special codes used reserved for internal use only.
TReX User Manual v2.14 Firmware IO Mirror Operation The IO MIRROR is the simplest self managed telemetry mode that mirrors the inputs of one TReX unit to the outputs of another TReX unit. SCADA monitoring and control is not possible in this mode of operation (see SCADA Configuration and Operation). This mode is intended for a simple system that allows remote outputs to be controlled and inputs monitored without any supervising equipment.
TReX User Manual v2.14 Firmware When IO MIRROR is enabled, configurable messages cannot be transmitted from inputs. If mirroring of some inputs and messages transmitted on other inputs is a requirement, this can be achieved by configuring some input message using the WTE output control protocol. After selecting a frequency to transmit on, the default settings will in many cases be enough for the system to be ready to test before deployment.
TReX User Manual v2.14 Firmware Input Handling Note: Please refer to Input Output Hardware Connection section on this manual for examples of how to connect the input and output pins on the TReX board. The TReX supports 8 programmable inputs. Each input can be programmed with a short message up to 50 characters in length. Input messages must always be formatted as WT Protocol. On start-up each input is read. By default only inputs that change from the start-up input state are processed.
TReX User Manual v2.14 Firmware *IN_CONFIG_H=2:0,0,0 Both input 1 and 2 are configured as per the full example details above. *IN_CONFIG_L=1:5,20,10 *IN_CONFIG_L=2:5,20,10 Configured messages to be transmitted once triggered.
TReX User Manual v2.14 Firmware Output Handling Note: Please refer to Input Output Hardware Connection section on this manual for examples of how to connect inputs and outputs to the TReX. The TReX supports up to 8 outputs. These outputs can be shared with special output functions such as the LINK FAIL output. Outputs are configured using the commands: *OUT_CONFIG *OUT_ID The outputs are controlled through messages received that conform to the WTE output control protocol.
TReX User Manual v2.14 Firmware WTE Output Control Protocol Introduction This section describes how to control the outputs of WTE Products via transmission payloads. The WTE protocol needs to be able to switch many outputs on, and many off in a single message. Receivers need to be able to be uniquely addressed, and in a manner that is maintainable.

Up to 8 outputs can be specified. - is the character ‘-’ O is the output to open AA is the value to set an analog output to (0-1023).
TReX User Manual v2.14 Firmware WTE Ack and Confirm Protocol Introduction This section describes how to use this protocol to invoke automatic acknowledging and optionally manual confirmation of messages sent/received. This protocol can also be used to message TReX units to display confirmation prompts. The use of this protocol is the heart of making two-way paging or messaging possible.
TReX User Manual v2.14 Firmware characters. ] is the character ']' Responses are all transmitted using the default settings for modulation type and protocol. The payload is also sent directly out the serial port and TCP sockets for when acknowledgement is required via IP. Typical Operation The base-station TReX sends single messages, or many batched together as required.
TReX User Manual v2.14 Firmware Example 2: Message payload to have delivery acknowledged and confirmed is transmitted. All units, go to Pukeko Place urgently.-[347-2-Turnout Y/N?] The remote TReX unit immediately displays: Remote TReX immediately responds with: ACK[347] If message has been accepted (by pressing the square “ENTER/ACCEPT” button) remote TReX responds with: ACC[347-Unit 41] Note that the “Unit 41”in the confirmation response is the TReX programmed unit ID.
TReX User Manual v2.14 Firmware of acceptance. Should the user ACCEPT the message to attend, the remote TReX transmits to the base-station the message: ACC[666-Unit A] where: 666 is the ticket id.
TReX User Manual v2.14 Firmware Store Forward Operation The TReX can operate as a stand-alone repeater to forward paging messages and also extend wireless serial operation. Transmit and receive configuration should be configured to be the same when forwarding messages. *RX_PROTO should equal the *TX_PROTO and *RX_MODE should equal *TX_MODE. Typically the TReX would be configured as follows: Delay of 2 second before forwarding, reject duplicate messages for 10 seconds.
TReX User Manual v2.14 Firmware Installation The TReX should be situated away from direct sunlight, extreme vibration and heat sources, and high power transmission sources. An external antenna correctly designed to operate at your intended frequency of operation will result in best performance. Dual VHF/UHF antennas may operate acceptably for your requirements. Do not situate the antenna immediately next to the antenna of a high power transmission source – position greater than 2 M from any other antenna.
TReX User Manual v2.14 Firmware Connecting to the TReX The minimum required connections for a usable system: 1. Connection to a 50 ohm antenna constructed for the frequency of interest. Mismatched antennas may result in increased current draw and reduced power output. 2. 13.

TReX User Manual v2.14 Firmware RS-422/RS-485 RS-422 and RS-485 use a differential electrical signal, as opposed to unbalanced signals referenced to ground as used by RS-232. Differential transmission uses two lines each for transmit and receive signals which results in greater noise immunity and longer distances between devices. These advantages make RS-422/RS-485 a better fit for industrial applications. RS-422 is point to point interface that allows for up to 10 receivers but only a single transmitter.
