1. Introduction
TRP-C34M is a 4-Port Modbus gateway.
There are two functions below:
Modbus RTU/ASCII serial master to Modbus TCP slave bi-diction.
Modbus TCP master to Modbus RTU/ASCII slave bi-direction.
The TRP-C34M is able to run under industrial environment stable, it provides 3KV optical
isolated protection between Ethernet interface and 4-port serial interface.
The TRP-C34M provides a watchdog timer function that allows the system to automatically
recover from a system crash. When the TRP-C34M microprocessor stop working correctly, the
watchdog timer waits for a preset period of time and performs a hardware reset.

2. Hardware Description
The following information is provided to give the user an understanding of how to connect the
TRP-C34M 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:Power LED keep on when the DC input.
SYS: The system boot time needs 36sec after SYS LED will blinking, it means that the device is
working.
4
TX/RX LED: COMA~COMD Transiting/Receiving Indicator.
2-3. Power Input
DC Jack: Power Input DC +10V to +24V. (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. RST button
Keeping pushes the RST button over 10-sec when power on, and the SYS and WiFi LEDs will
blinking then TRP-C34M will be back to factory default setting.
3. Install TRP-C34M Hardware
STEP1: Please connect the power source, the PWR LED will on and wait the SYS LED will
blink.
STEP2: Connect TRP-C34M with internet port by RJ45 LAN cable.
*The TRP-C34M 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-C34M with RS232, RS422 or RS485 with Modbus RTU or ASCII
protocol.
3-1. RS485 Wiring
3-2. RS422 Wiring

3-3. RS232 Wiring
The RS-232 supports 2 channels plus Signal Ground and is configured as DTE like a computer.
Signals are single ended and referenced to Ground.
*Please try to connect pin1,4,6 and Pin 7,8 together if RS232 device does not work.
4. How to configure TRP-C34M
There are 2 ways to access the Server Properties and program the TRP-C34M.
a. Using the IoT Device Finder utility.
6
b. Using the WEB Server
7
4-1. Using IoT Device Finder utility.
The “IoT Device Finder” utility performs several functions:
A: Searching for TRP-C34M connected to the network.
B: Displaying and changing the configuration of TRP-C34M.
C: Upgrading the TRP-C34M firmware.
D: Save, reboot and back factory settings.
4-2. Searching LAN for TRP-C34M
Once TRP-C34M is connected to the LAN the IoT Device Finder utility will search it and display
it in a window by name, IP address, Mac….Information, please click the “Find” button to looking
for that.
The IoTdevice Finder utility will find the TRP-C34M.
* Please make sure the PC’s network IP 3 segment as same as TRP-C34M.
Such as PC’s network IP should set up 192.168.1.xx ,and the TRP-C34M’s default IP is
192.168.1.100.

4-3.Configuring Server Properties
Click the GoTo button, when the login prompt appears, login using the administrator and
password. Click Log In.
the factory default setting below:
User Name: admin
Password: admin
Please click the “Log In” button after you completed the User Name and Password.

4-4.System web UI:
Admin Password:
Maximum 25 chars.
Confirm Password:
Input the password again.
Auto Reset (Minutes):
Sets the amount of time a user can remain idle before being reset.
Device Name:
Device server name.
Device Description:
Device is described.
System Up time:
Device power on time.
Firmware Release:
Firmware Release time.
10
4-5.Network web UI:
Wireless:
Option, it should be disabled.
Ethernet:
Static Mode:
Selecting Static IP requires the user to assign the IP information for the device manually.
*Please make sure your host pc the network segment as same as this IP.
Such as: PC:192.168.1.xx, and the device is 192.168.1.100.
DHCP Mode:
Selecting this mode will cause the device to obtain an IP address from the local DHCP server.
IP Address: The Gateway IP address.
Mask
The default LAN Netmask is configured for a Class C address. This may be reconfigured by the
user.
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.
