Introduction Introduction Thank you for purchasing the AGM Spread Spectrum Radio (SSR). The AGM Spread Spectrum Radio modem provides a variety of cost effective data communications possibilities. This manual covers installation and setup of the more commonly used configurations. Screw Terminal Connections...
Default communications is set for 9600 bps, 8 data bits, no parity and 1 stop bit. The SSR may also be configured for 1200, 2400, 4800, 19200, 38400, or 57600 bps. 7 bit and 8 bit parity options are also available through configuration.
Introduction General Specifications Ports – 1 RS232C, 1 RS485 Baud Rate – RS232C/RS485, 1200, 2400, 4800, 9600, 19200, 38400, or 57600 bps Status Indicators - 7 Operating Temperature Range, -20/80 deg C Adjustments – Operator configurable locally from a PC Power –...
Short range antenna (Under 1500 feet) Your SSR is shipped with a whip antenna. If you will not be installing the SSR in an enclosure and if operating over a short range, simply attach this whip antenna to the antenna connector on the SSR.
When power is applied the “P/X” light should be on. The “F” light indicates the supply voltage is too low or a failure of the SSR. If neither lights are on or if the “F” light is on check your input voltage.
SSR. Connecting to AGM Data Handler (DH) RS232 To connect a SSR to a RS232 Data Handler you will need a 9 pin female to 9 pin male null- modem cable. 1. Plug one end of the RS232 cable into the 9 pin male connector on the Data Handler.
Connecting to AGM Universal Web Station (UWS) RS-232 connection To connect a SSR to a UWS Data Handler you will need a 9 pin female to 9 pin male straight through cable. 1. Plug one end of the RS232 cable into one of the 9 pin male connector on the UWS.
2. Plug the other end of the RS232 cable from the PLC into the 9 pin female D connector on the top of the SSR 3. Power up both the SSR and PLC. The “2” light should be on. If off then your PLC may be using either 3 wire RS232.
For best throughput we recommend you set up your system to match the SSR data rate of 9600 bps. If this is not practical then the SSR will need to be configured to match the data rate and data format used by your system.
Turn off any handshaking. If you have changed the communications settings use those setting. The SSR operates similar to dial up modems. It uses a command mode sequence and all commands are prefixed by AT. The AT command set however is not like modems and all commands must either be separated by commas or carriage returns.
Configuration Save Changes (WR) Enter “ATWR” to save the changes in the SSR non-volatile memory. On power up the SSR will revert to previously stored settings. Baud Rate (BD) Baud Rate Command 1200 ATBD0 2400 ATBD1 4800 ATBD2 9600 ATBD3...
SSR’s as Repeaters SSR’s as Repeaters Store and Forward The modules can be configured as simple “store and forward” repeaters by attaching a hardware loopback (“repeater”) adapter that loops received data back into the module for retransmission. This mode allows the radio to store and forward up to 430 bytes.
ATHP=0 for all “module 1”s. Application Specific Because SSR modules operate in a peer-to-peer mode (no module must be designated a master of the network) a system designer can take advantage of flexible network topologies.

Diagnostics and Trouble Shooting Diagnostics and Trouble Shooting Indicator Lights Seven indicator lights are included on the front of a SSR to aid in troubleshooting your SSR installation. Light Description RS485 Mode RS232 Mode RS232/RS485 Transmit. Light flashes with each character transmitted from the SSR to connected device.
1 and 5 on the green connector and cycling the power. When in this mode the SSR will continuously transmit to the RS232 or RS485 connection a count with each number followed by carriage return / line feed. The count will be transmitted at the current baud rate and data format.
