GENERAL DESCRIPTION
RM169-1 includes 1 optically isolated digital inputs and 1 digital relay outputs, an RS-232/485 serial interface,
this radiomodem is fully configurable via software. The embedded inputs and outputs allow the RM169-1
radiomodem to be used in data acquisition and remote control applications.
RM169-1 has 4 operating modes that are software programmable: radiomodem, mirror point to point, Modbus
slave, or Modbus master, allowing greater flexibility in the field.
RM169-1 uses routing tables to obtain fewer collisions in complex networks and can also be used as a Modbus
hub, allowing 8 Modbus modules (inputs and/or outputs) to be connected through the RS-485 port. (RM169-1
will power these modules).
Data Encryption 128bit AES (Advanced Encryption Standard) ensures transmitted data security.
A power-saving function is built in, to activate inputs only when required, allowing for extended battery life.
Function available for each operating mode.
