TRP-C37 Ethernet to RS-232/422/485 Converter Data Communication


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 long distance serial quality , the RS485 interface built-in hardware decoder ensure RS485 data without lost and fast direction switching , Specify hardware can keep on line RS485 device working fine; Increase external watchdog function will auto reset when Ethernet serial server or power fail, if careless lost password or IP that can easy to back to factory by external switch. The TRP-C37 operates in “Direct IP Mode”, “Virtual COM Mode”, and “Paired Mode”. It has one DB-9 serial port for RS232 connector and screw terminal block for RS422/485 and power . The Ethernet port support Auto-MDIX and Auto-select 10/100MB. TRPC37 also offers a Heart Beat feature to ensure a reliable communicating connection. The TRP-C37 support maximum connection 16 host clients to link the one serial server that is easy to operate in Modscan32 and Modbus Poll application uses Virtual-COM mode and Pair Mode. When TRP-C37 working at industrial environment, if the voltage is unstable , The TRP-C37 built-in power detection circuit can prevent the power fail cause of the system boot fail. In network security, the TRP-C37 is able to set up 8 sets host IP, only these host IP can access the TRPC37.
