If your system is configured on Peer-to-Peer mode, by default, if the Slave unit does not receive a response from the master within 20 seconds of any polling sequence, and if the ”Set Rest Voltage On Comm Error” is enabled, an alarm will sound on the Slave unit and depending on alarm parameters set, would cause the Slave’s outputs to be set with the user defined resting voltages.
Retries: In Peer-to-Peer mode, this parameter determines the number of consecutive failed polling attempts before a communications failure occurs. It is not recommended to set the number of retries higher than 10 attempts. Large numbers may cause an unnecessary delay in communications failure response time; a low number may cause the system to prematurely fail. This parameter has no affect in Modbus mode.
Output Power: This parameter determines the RF Power output on some RTU’s. If a respective RTU does not support a variable RF power out the parameter will continue to display “Output Power”.

The “ID” field has a dual purpose, as the controller number when in peer-to-peer mode and the Modbus slave address field when in MODBUS mode.
If Modbus is selected, the Radio ID will automatically appear and the “ID” field will automatically change to “MODBUS ID.”
If your controller is programmed in Modbus mode, the ID field will change to the Modbus Slave address. Valid addresses are from 1 to 255. Keep in mind that the Modbus master you are interfacing to may not support the full spectrum of slave address IDs. Please refer to your device user’s manual.
