1. Introduction

The TRP-C37M which is able to analyzes the protocols between Modbus TCP and Modbus

RTU / ASCII. It able to assign the UID of Modbus TCP slave from Modbus Serial Master.

The TRP-C37M which is suitable industrial environment Ethernet serial server, wide range power

input and serial communicate protection, It Built-in surge, over current, over voltage ensure

RS422 / 485 serial communication quality; if user lost password that can fast back to default by

external switch.

The TRP-C37M can as serial server that support 3 operates mode, "Direct IP Mode", "Virtual

COM Mode", and "Paired Mode", these modes are supported Modbus RTU / ASCII protocols.

The TRP-C37M 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.

In network security, the TRP-C37M is able to set up 8 sets host IP, only these host IP can access

the TRP-C37M.

The TRP-C37M provides a watchdog timer function, The Watchdog timer allows the system to

automatically recover from a system crash. When the TRP-C37M MCU stop working correctly,

the watchdog timer waits for a preset period of time, and performs a hardware reset .

When The TRP-C37M working at unstable voltage industrial environment, the power detection

circuit can prevent the power fail cause of the boot fail then auto re-boot.

The TRP-C37M will be auto detects function which will be auto connect when the LAN

disconnect then re-connect or power off then power on.

2. Hardware Description

The following information is provided to give the user an understanding of how to connect the

TRP-C37M to the LAN and serial device. A review of the switch settings and the functionality of

the LED’s are also provided.

2-1. Panel layout

2-2. LED indicator

PWR LED: System is ready.(Blinking)

LINK LED: Ethernet cable connection and data active.

TX/RX LED: UART Transiting/Receiving Indicator.

2-3. Power Input

DC Jack: Power Input DC +10V to +30V. (Please use the 5.5*2.1mm DC JACK).

There are two types power input.

a. Use the plug of power adaptor than plug in the DC jack on the side.

This approach also allows the user to provide additional power to other devices using the

terminal from EU regulation.

b .Wiring terminals on the EU regulation

2-4. Reset Button

Push the reset button will Re-Boot.

2-6. How to back factory by external DIP Switches 1,2

Power off then adjusts the SW 1, 2 to ON ON position then power on until the PWR LED blinking.

Adjusts the SW 1,2 to OFF,OFF.

3. Install TRP-C37M Hardware

STEP1: Connect power source with TRP-C37M, the PWR LED will blinking.

STEP2: Connect TRP-C37M with internet port by RJ45 LAN cable.

If the cable is properly connected the “LINK” LED will light up.

*The TRP-C37M Support Auto-MDIX, A straight-through or crossover Ethernet

cable can be used to make a connection directly to the HUB/Router/PC.

STEP3: Connect TRP-C37M with RS232 or RS422/485 RTU/ASCII of serial device.

The TRP-C37M has one DB-9 male connectors for RS232 connection and a screw

terminal connector for RS422/485 connection.

The DB-9 serial port is DTE interface. A null modem cable is required to make a

connection between the COM port on a PC and the TRP-C37M serial port. A straight

through cable is required to connect the TRP-C37M serial port to a DCE device.

The screw terminal connector accepts AWG #12 ~30 wires.

3-3. RS232 Wiring

The RS-232 supports 8 channels plus Signal Ground and is configured as DTE like a computer.

Signals are single ended and referenced to Ground. To use handshaking, Flow Control must be

set to RTS/CTS during Configuration. Refer to the Pin out table for connections.

4. How to configure TRP-C37M

There are 3 ways to access the Server Properties and program the TRP-C37M.
