1. Introduction

TRP-C37 is suitable industrial environment Ethernet serial server, wide range power input and
serial communicate protection, Built-in surge, over current ,over voltage ensure RS422/485
serial communication quality ; Increase watchdog function will auto reset when Ethernet serial
server or power fail, if careless lost password or wrong setting value that can fast back to factory
by external switch.

TRP-C37 support 3 operates mode, “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode”,
RS232 interface has one D-SUB 9pin connector and screw terminal block for RS422/485. The
Ethernet port support Auto-MDIX and Auto-select 10/100MB.

TRP-C37 offers maximum connection 16 host clients to link the one serial server, it is easy to
operate in Modscan32 and Modbus Poll many application uses Virtual-COM mode and Pair
Mode.

TRP-C37 provides a watchdog timer function, The Watchdog timer allows the system to
automatically recover from a system crash. When the TRP-C37 MCU stop working correctly, the
watchdog timer waits for a preset period of time, and performs a hardware reset.
When TRP-C37 working at unstable voltage industrial environment, the power detection circuit
can prevent the power fail cause of the boot fail then auto re-boot.
