Trycom TRP-C37MA

Remote monitoring serial device

In addition to Modbus TCP and RTU/ASCII function, the TRP-C37MA is able to remote monitoring serial device. There are 2 models to choose from: 

  1. Automatic monitoring mode: The Serial device must be sends a single pulse to TRP-C37MA continually per 30 seconds. If serial device do not send a single pulse over 30 seconds, the TRP-C37MA will be actives the relay. 
  2. Manual mode: If the serial device need to restart, user can feel free to set the relay enable through the TRP-C37MA web configuration.
