XCite RF Modem in an RS‐422 environment RS-485/422 Connection Guidelines The RS-485/422 protocol provides a solution for wired communications that can tolerate high noise and push signals over long cable lengths. RS-485/422 signals can communicate as far as 4000 feet (1200 m). RS-232 signals are suitable for cable distances up to 100 feet (30.5 m). RS-485 offers multi-drop capability in which up to 32 nodes can be connected.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 3. RF Modem Operation 3.1. Serial Communications 3.1.1. RS-232 and RS-485/422 Data Flow The XCite RF Modem can enable a host device to communicate wirelessly. To transmit, the host device simply sends serial data to the XCite RF Modem pins. The RF modem then converts the data into FCC-approved RF data. Once transmitted, the RF data can be detected by receiving XCite RF Modems, checked for integrity and then sent to a receiving device.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 3.2. Modes of Operation XCite RF Modems operate in five modes. Figure 3‐03. Modes of Operation 3.2.1. Idle Mode When not receiving or transmitting data, the RF modem is in Idle Mode.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 3.2.3. Receive Mode If a modem detects RF transmitted data while operating in Idle Mode, it transitions into Receive Mode to start receiving packets. Once a packet is received, it goes through the receiving-end of a CRC (cyclic redundancy check) to ensure that the data was transmitted without error. If the CRC data bits on the incoming packet are invalid, the packet is discarded. If the CRC is valid, the packet is placed the DO Buffer.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 3.2.4. Sleep Modes Software Sleep Sleep Modes enable the modem to enter states of low-power consumption when not in use. Three software Sleep Modes are supported: • Pin Sleep (Host Controlled) • Serial Port Sleep (Wake on Serial Port activity) • Cyclic Sleep (Wake on RF activity) In order to enter Sleep Mode, one of the following conditions must be met (in addition to the modem having a non-zero SM parameter value): 1.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] into Idle Mode to listen for valid data packets and de-asserts when the modem returns to Sleep Mode. The modem remains in Sleep Mode for a user-defined period of time ranging from 0.5 seconds to 16 seconds (SM Parameters 3 through 8). After this interval of time, the modem returns to Idle Mode and listens for a valid data packet for 100 ms. If the modem does not detect valid data (on any frequency), the modem returns to Sleep Mode.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 3.2.5. Command Mode AT Command Mode provides access to AT-Settable parameters. These parameters extend flexibility in configuring modems to fit specific design criteria such as networking modems. Not all of the parameters in the XCite Module can be adjusted using AT Commands. AT Command Mode To Enter AT Command Mode: 1. Send the 3-character command sequence "+++" and observe guard times before and after the command characters.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 4.

9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 4.4. Automatic DIP Switch Configurations Each time the RF Modem is powered-on, intelligence on the MaxStream Interface Board (located inside the RF Modem) sends AT Commands that program the modem based on positions of the DIP Switch. Automatic configurations that take place during the power-on sequence affect RF Modem parameter values as shown below.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 4.5. Command Descriptions Commands and parameters are listed alphabetically. Parameter types and categories are designated between "< >" symbols. For example: . "AT Command" is the command/parameter type and "Networking" is the command/parameter category.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] BT (Guard Time Before) Parameter BT Parameter is used to set the DI pin silent time that precedes the command sequence character (CC Parameter). By default, 1 half of a second (500 milliseconds) must elapse before entering another character.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] CS (DO2 Configuration) Command CS Command is used to modify the behavior of the CTS signal such that it either provides RS-232 flow control, enables RS-485 transmission / reception or determines RS-422 transmit enable. By default, CTS provides RS-232 flow control. CS Parameter must be adjusted for the modem to operate in RS-485/ 422 environments.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] FH (Force Wake-up Initializer) Command FH Command is used to force a Wake-up Initializer to be sent on the next transmission. WR (Write) Command does not need to be issued with FH Command. Use only with cyclic sleep modes active on remote modems. AT Command: FH FL (Software Flow Control) Parameter FL Parameter is used to adjust serial flow control.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] HT (Time before Wake-up Initializer) Parameter If any modems within range are running in a "Cyclic Sleep Setting", a wake-up initializer must be sent by the transmitter for the other radio modems to synchronize to the transmitter [see LH ("Wake-up Initializer Timer") Command].
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] LH (Wake-up Initializer Timer) Parameter LH Parameter adjusts the duration of time in which the wake-up initializer is sent. When receiving modems are put into the Cyclic Sleep Mode, they power-down after a period of inactivity (specified by ST (Time before Sleep) Parameter) and will periodically awaken and listen for transmitted data.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] MK (Address Mask) Command MK Command is used to set the radio modem address mask. All RF packets contain the Destination Address of the transmitting radio modem. When an RF packet is received, the transmitter's Destination Address is logically "ANDed" (bitwise) with the Address Mask of the receiver.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] RT (DI2 Configuration) Parameter RT Parameter enables RTS Mode. Parameter Ranges: 0 - 1 Parameter Configuration 0 disabled 1 Enables RTS Handshaking Default Parameter Value: 0 Number of bytes returned: 1 SB (Stop Bits) Parameter SB Parameter allows the user set the number of stop bits used in data transmission.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] SM (Sleep Mode) Parameter SM Parameter is used to adjust Sleep Mode settings. By default, Sleep Mode is disabled and the radio modem remains continually active. SM Parameter allows the radio modem to run in a lower-power state and be configured in one of eight settings. Parameter Ranges: 0 - 8 Parameter Configuration 0 No Sleep 1 Pin Sleep 2 Serial Port Sleep 3 Cyclic 0.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 5. Advanced Networking 5.1. Addressing The XCite Radio Modems utilize three layers of addressing to communicate between radio modems. The network layers are depicted below. Only radio modems with the matching addresses are able to communicate. The main layers of XCite Networking and Addressing are: • Vendor Identification Number (ATID) • Channel (ATHP) • Destination Address (ATDT) Figure 5‐01.
9XCite‐PKG‐R™ RS‐232/485 RF Modem – Product Manual v2.1 [2007.01.04] 5.1.2. Channel (ATHP) Channels provide a network layer from which channels can be used for isolation. HP (Channel) Parameter is used to define channel values. Hopping Channel Mode: HP Parameter value range is 0 through 6 Single Frequency Channel Mode: HP range is 0 through 0x18 (decimal range: 0 - 24) In "Hopping Channel Mode", each channel utilizes a different pseudo-random hopping sequence to navigate through shared hopping channels.
