Indicates a hazard that can cause severe personal injury, death, or substantial property damage if the warning is ignored.
equipment being controlled, or to anything in the area in which such equipment is located. All integrated control systems should be designed for “fail-safe” operation so that a temporary or permanent loss of signal will not endanger any person, critical process, or equipment (refer to the beginning of the safety section for further explanation). The system design should ensure that the equipment being controlled will default to its safest state in the event of signal loss.
Be sure the FDQ02T power, the power to the equipment that is being connecting to it, and the DC power source are all turned off before wiring and connecting the power cable. Be sure that the supplied power is within the specified range (3.5 to 7.0 VDC). Voltages outside the specified range may damage the FDQ02T. Be sure that the power source has sufficient current capacity. Insufficient current may cause the unit to malfunction.
Multipath problems occur easily at frequencies in the 2.4 GHz band. When multipath problems are present, moving the antenna as little as 10 cm may result in improved communication or, conversely, worsened or complete loss of communication. Futaba recommends that the mounting position of the antenna be determined after testing and verifying optimal communication conditions.
I I .I V Environm e nt a l Sa fe t y H a za rds a nd N ot e s If the FDQ02T has been stored at a temperature beyond the specified operating temperature range for the system, it may not function properly. Allow it to return to normal temperatures before use. Refer to APPENDIX A – TECHNICAL SPECIFICATIONS for the actual operating temperature range. The FDQ02T is a precision electronic device with a rugged design that is intended for industrial applications.
Ope ra t iona l Sa fe t y H a za rds a nd N ot e s Before each use of the FDQ02T, ensure that the area where the equipment will be operated is clear of people or obstacles that may affect its safe operation.

SECTI ON 3 3 11 SYSTEM OPERATION
3 .1 Pa c k e t t ra nsm ission m ode 3 .1 .1 Abst ra c t In the Packet Transmission mode, the communication is carried out by the follows procedure: (1) Once the power of the modem is turned on, the modem becomes the State for Reception. (2) The transmission command “TXT” or “TBN” makes the MODEM to the State for Transmission. (3) One transmission command can send one packet. The maximum length of the user’s message is 255 bytes for a packet.
Example : RXT0015HELLO [CRLF] (2) Text data transmission via repeater Transmission : @TXT[repeater address] [destination address][message][CRLF] Example : @TXT003012HELLO [CRLF] Reception Example : RXT[repeater address] [sender address][message][CRLF] : RXT003015HELLO [CRLF] (3) Binary data transmission Transmission : @TBN[destination address] [the number of bytes of the message] [message] [CRLF] Example : @TBN012005HELLO [CRLF] Reception Example : RBN[sender address] [the number of bytes of the mess
3 .2 H e a de r-le ss St re a m m ode 3 .2 .1 Abst ra c t The Header-less Stream mode, a special Packet Transmission mode, does not require the procedures for transmission commands that are necessary in the Packet Transmission mode, but requires only inputting transmission data directly. (1) The destination address can be set in memory register or by command. (2) The transmission triggers such as terminator, timeout and a specified number of bytes can be set in the memory register.
3 .2 .3 T ra nsm ission t rigge r In the Header-less Stream mode, transmission starts under the following conditions. (1) Terminator mode A designated terminator or data of 255 bytes or larger is entered. (2) Timeout mode No data has been entered for more than the specified time or data of 255 or larger is entered. 3 .
( 1) The modem1 and 2 transmit messages at the same time. ( 2) Both modems wait for “ACK”, but they time-out. ( 3) Of the two modems, the one that has finished the random-time earlier (modem2 in this case) retransmits its message. ( 4) Receiving a message retransmitted during the random-wait, the modem1 receives the whole message and then returns “ACK”. ( 5) The modem1 does not output but keep its received message and transmits its own message. ( 6) The modem2 returns “ACK.
3 .4 Com m unic a t ion t im e The time consumed for each communication sequence in the Packet Transmission mode is as follows. (1) Time for entering a transmission command The time consumed for entering a transmission command to the modem from its terminal depends on the communication parameters between them. Parameters are: １．Transmission rate (300ps to 115.
(9) Time for reception process Approximately 0.2ms is consumed for the receiver modem to check the address in the data and other information sent from the sender modem. The receiver modem recognizes the data having passed the check and outputs it to its terminal. The next example shows an approximate time necessary for sending a message of 10 bytes when the parameters are 9600bps for transmission rate, 8 bits for data length, no parity, one stop bit and one start bit.
3 .5 Re pe a t e r func t ion This function is not installed in the modem at present. This section is only for explanation for the future upgrade. 3 .5 .1 Abst ra c t Using repeaters is useful in extending communication area and eliminating dead-point area where radio signal intensity is insufficient. The repeater function can coexist with the modem function.
3 .6 Fre que nc y Cha nne l The FDQ02T can operate on 22 available frequencies between 2405.376 MHz and 2448.384 MHz with 2.048 MHz separation between each frequency.

4 .3 T e rm ina l Soft w a re Se t up for M e m ory Re gist e r Cont rol Communication or terminal software is necessary to set the memory registers. Nearly any PC communication software can be used. Launch the communication software and set the terminal’s communication parameters as shown below. Refer to your specific communication software instructions how to set these parameters.
CAUTION If the memory contents are lost or corrupted, they can be restored to original default settings by reinitializing them. (See the section below titled p.25 MEMORY REGISTER INITIALIZATION) Input character arrays of commands quickly and sequentially. Too slow input (taking more than 5 seconds in the initial setting) results in command error. 4 .4 .
4 .5 Com m a nd Cont rol Some FDQ02T parameters can be changed by issuing commands from the terminal equipment. Various applications can be supported with the flexibility that command control offers. Command Entry • When a command is issued to the modem from the terminal equipment, a command header (one byte character) should be used the modem to acknowledge the command from ordinary data.
SECTI ON 5 5 MEMORY REGISTER DESCRIPTION 27
5 .1 M e m ory Re gist e r De sc ript ion The FDQ02T modem contains 28 memory registers which are used to control and store communication parameters and operation mode settings. After rewriting new register settings, the power must be cycled, a hardware reset asserted, or a software RST command is issued to validate the new settings.
REG00: Own (sender) address • • • [default value: 000] This register is used to set the address of a modem. Valid values are from 000 to 254. The value in this register is used as a sender address in every data packet being sent. When the address-check function is used, it is possible to receive a packet if the packet contains such value as a destination address. REG01: Reserved • [default value: 240] The FDQ02T does not use this register. Keep the default value as it is.
REG06: Frequency pattern • • • [default value:00H] This register is used to set a frequency pattern. The valid values are from 00H to 15H. To establish communication in a system, the same frequency pattern should be used. In contrast, to let multiple systems operate in the same area, each system should have different frequency patterns. When using multiple systems in the same area, frequencies may periodically match and interfere with each other even if the systems are using different frequency patterns.
REG13: Buffer Data Timeout • • • • [default value: 1EH] This register is used to set the waiting time to clear the content of the buffer after the last change in the buffer. Valid values are from 000 to 255 seconds with an increment of 1 second. The default value is 30 seconds. If the Buffer Data Timeout is not necessary, set it at “0.” This value should be longer than the Data Input timeout (REG26).
REG18: Communication Setting 1 [default value: 8CH] Bits 7 – 6: Protocol bit 7 0 0 1 1 bit 6 0 1 0 1 Setting Data transpalent mode Reserved Packet transmission mode Headerless stream mode Table 5–7: Protocol Bits 5: Reserved • The FDQ02T does not use this register. Keep the default value as it is. Bit 4 Transmission format 0 1 transmit in the text form (default value) transmit in the binary form Table 7–4 Transmission format • • Selects the transmission format.
• When the source address checking is active and the source address in the received packet header does not match the destination address setting (REG02), the data is discarded (data cannot be received).
REG20: Wired communication Setting 1 [default value: 05H] Bit 7: Data Length 0 1 8 bit data bytes (default value) 7 bit data bytes Table 5–13: Data Length Settings Bit 6: Parity Bit 0 1 No parity bit (default value) Parity bit Table 5–14: Parity Settings Bit 5: Even/Odd Parity 0 1 Even parity (default value) Odd parity Table 5–15: Odd/Even Parity Settings • Invalid when bit 6 is set to 0, without parity.
REG21: Wired communication Setting 2 [default value: 09H] Bits 7 – 5: Reserved • The FDQ02T does not use this register. Keep the default value as it is. Bit 4: Command Header 0 1 Use REG 10 character Use Break signal Table 5–16: Command Header Bit 3 - 2: Reserved • The FDQ02T does not use this register. Keep the default value as it is.
REG23: Wired communication Setting 4 [default value: 00H] Bit 7 - 5: Reserved • The FDQ02T does not use this register. Keep the default value as it is. Bit 4 : CR/LF addition/deletion (1) Setting at the headerless stream mode does not add CR/LF code to the received data (default value) adds CR/LF code to the received data 0 1 Table 7–6: Addition of CR/LF code • • In the headerless stream mode, setting is made whether the CR/LF character is added to the received data or not.
REG24: Reserved • [default value: C0H] The FDQ02T does not use this register. Keep the default value as it is. REG25: Reserved • [default value: 40H] The FDQ02T does not use this register. Keep the default value as it is. REG26: Data input timeout • [default value: 00H] Sets the vacant duration time interval to recognize as the end of the message data input in the headerless stream mode. REG27: Reserved • [default value: 00H] The FDQ02T does not use this register. Keep the default value as it is.
SECT I ON 6 6 COMMAND SET DESCRIPTION 39
6 .1 Com m a nd Se t De sc ript ion This section provides a description of each command available in the FDL command set. The table below lists each command and it applicability in each operation mode.
ARG Reference All Memory Registers Syntax ARG{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response All settings are indicated (REG00 to REG27) N0: command error (Except 485 mode) Function Recalls the contents of all 28 memory registers.
DAS Reference and Set Destination Address Syntax DAS(set destination address) set destination address Response xxx P0 N0 : the desired destination address (000 to A23) : current value (reference) : command accepted (setting) : command error Function References or sets the destination address of the modem connection established with in the data transparent mode and headerless stream mode The current DAS value can be referenced by entering the command with no parameter.
Notes The range available for measurement is –40 dBm to –100 dBm. Since the signal strength indication has a slight error in its value, use this result for your ‘rule of a thumb’ reference. This command outputs the strength of last received packet. HOP Refer to or set frequency pattern Syntax HOP HOP(:pattern number) Pattern number : 00 ~ 21 Response xx P0 N0 : when referring : normal end (when setting) : command error Function This command refers to or sets frequency pattern.
Notes Custom settings of all memory registers are lost when this command is executed. If the group address (REG01) is designated while RS485 multi-drop connection is being made in the RS485 mode, the local station address of all modems will be initialized to 000. Exercise care when issuing this command. For a list of the factory default values, see the section titled p.27 MEMORY REGISTER DESCRIPTION.
N0 : command error (Except 485 mode) Function Enables output of any data received via the wireless link to the terminal equipment. This command enables serial data output after it has been disabled with the ODA command. When the modem’s power is turned on (or a reset), the modem is in the state to enable the received data output. Example >@ODA CR/LF
RDA Disable Wireless Reception Syntax RDA{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22). Response P0 N0 : command accepted : command error (Except 485 mode) Function Disables wireless reception in the packet transmission mode. The status when the modem is powered ON or reset follows bit 7 of REG22.
While rewriting the memory register, do not turn off the power until response is output. Otherwise, the memory registers content may be collapsed. When the response of the memory register write error is output, set the values after initializing the memory register. REN Reception Enable Syntax REN{Local Station Address} Local Station Address : local station address for 485 mode (000 to A22).
To use it more securely, it is recommended to readout the local serial ID code with TID command and pad it (either all or a part of it) in the transmitting packet. When no packet is received, “All Zero” is displayed as the result of this command execution. The serial ID code is no relation with ID code setting of REG04 and 05.
This function is used to save the current consumption when no transmit/receive are required. Example >@ROF CR/LF @RON CR/LF
Example >@RST CR/LF
XXXXXXXX Bit Name 0 1 2 3 4 5 6 7 Connection Reception Output message Receive buffer Transmit buffer Reserved Reserved Reserved Status 1 Connected Disabled Disabled Data exist Data exist - 0 Disconnected Enabled Enabled Data empty Data empty - Figure 6–2: Modem Status Bit Description Example >@STS CR/LF <00001010 CR/LF : read the current status : Received data exist, Output message enabled, Reseption disabled ,Disconnected.
TID Display Local Station Serial ID Syntax TID{Local Station Address} Local Station Address : local station address for 485 mode (000 to 999). Response XXXXXXXXXXXX : displays the local serial ID code (12 digits) N0 : command error (Except 485 mode) Function Readout the local serial ID code of the modem and display it. This command corresponds to RID command. The local serial ID code consists of 12 digits; upper three digits are 0 and the lower 9 digits are the product serial number of the modem.
The command accompanying a destination address requests a connection to the destination address. The command without a destination address requests a connection to the address defined by the DAS command. The modem that has received a connection request starts actions of the TS2 immediately. The modem to which the command is entered is called “TS2 master.” The destination modem is called “TS2 slave.” The TS2 slave does not output any measurement results.
