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.

b. WEB Server

8
c. Serial Console.

9
4-1. Using TRP-C37X DSM Utility.
The “TRP-C37X DSM utility” software performs several functions:
A: Searching for TRP-C37 connected to the network.
B: Displaying and changing the configuration of TRP-C37.
C: Upgrading the TRP-C37 firmware.
*Refer the Firmware upgrade help file.

DHCP
If DHCP is disabled, it allows user setting the IP address, Subnet mask, Gateway.
If DHCP is enabled ,the IP address, Subnet mask, Gateway address will be dynamically
configuration by DHCP server such router.
When “DHCP” is enabled ,but the DHCP server is not available on the network, the TRP-C37 will
timeout then back to factory setting IP=192.168.1.1.
Server Listening IP
The TRP-C37 IP address.
Server Data listening port
RS232/422/485 port address.
Client Destination IP
When user using the paired mode, the client setting need to input Server IP and PORT which
one need to connect.
Client Destination port
RS232/422/485 port address.

Netmask

11
The default LAN Netmask is configured for a Class C address. This maybe reconfigured by the
user.
Gateway
Input the gateway IP address that can be allows users to access the serial server from internet.
DNS
Short for Domain Name System, an Internet service that translates domain names into IP
addresses. Because domain names are alphabetic, they're easier to remember. The Internet
however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS
service must translate the name into the corresponding IP address.
Transmit timer:1~500 ms/Unit
Time interval to send out serial data char packet.
*The function main support serial data input to TRP-C37 RS232/422/485 port, if serial data
is a mass of serial data over 1K Byte ,Trying to adjust the Timer to 200ms.
Hear Beat: Disable /Enable
When Hear Beat enable, the TRP-C37 allows user open a TCP 5300 port, 10 sec interval to
send out data char packet that provides a easy way to ensure the communications between Host
PC Client and server devices.
Maximum Connection: 1~16
The function allows the user to configure the TRP-C37 in Server mode adjust 1~16 TCP client
host connections.
TCP Keep Alive: 1~7 /Minute
When TRP-C37 in Server mode, the TRP-C37 without data over the 1~7 Min setting value,
The TRP-C37 will be disconnect TCP.
When TRP-C37 in Client mode, the TRP-C37 without data over the 1~7 Min setting value,
The TRP-C37 will be reconnecting TCP.
