1. Introduction.

The TRP-C31M, MODBUS gateway allows the legacy MODBUS RTU/ASCII devices to operate on

a MODBUS TCP network. It allows either MODBUS serial master or slave to communicate with

MODBUS TCP’s slave or master. When TRP-C31M function as “MODBUS TCP masters to

RTU/ASCII slaves”: It allows multiple MODBUS TCP masters to communicate with a MODBUS

serial network. the queries from different masters are pipelined and processed one by one. When

TRP-C31M function as MODBUS RTU/ASCII master to MODBUS TCP slaves: it can connect up to

8 MODBUS TCP slaves. User can specify a UID range for each MODBUS TCP slave. TRP-C31M

provides inactive timeout that allows user to specify a time period to disconnect TCP/IP connection

to prevent one connection slot was occupied if there is no activity in the network., or prevent any

another connection again. A friendly management software provides user an easy way of

configuration over Ethernet. TRP-C31M can work at Loop back Mode, all data is sent back

immediately. This feature makes the connection testing easy. The industry standard DIN rail and

panel mount design enable user a fast and professional installation.

2-3. LED display

PWR LED: System is ready.

RX LED: Data receiving.

TX LED: Data transmitting.

2-4.Reset Button

The reset button can be found between the switch and terminal block. To reset the unit manually

apply power, insert a small plastic tool, and press lightly depressing switch. Hold for 1 second and

release. The Link and Run LED will go out and turn back on.

2-5. Dip Switches

A double DIP switch allows the TRP-C31M to be entered into Console/Loop back/Default/Data

Mode.

When all these switches are moved into the ON position, theTRP-C31M enters Console Mode,

allowing configuration of the TRP-C31M from a PC running a terminal program such as

Hyper-terminal. When the TRP-C31M enters Console Mode, the Console Mode screen will appear

in the Hyper-terminal program window. The serial port settings must be 8-N-1 at 9600 baud.

When the DIP switches are switched to the ON OFF position, the TRP-C31M will work at Loop back

Mode, all data is sent back immediately.

When the DIP switches are switched to the OFF ON position, the TRP-C31M will revert to its factory

version firmware no matter what newer firmware has been upgraded.

When all of the DIP switches are switched back to the OFF position, the TRP-C31M will enter Data

Mode (RS-232, RS-422 or RS-485).

3. TRP-C31M typical application.

3-1. Ethernet master link to multiple serial slaves (up to 31)

3-2. Serial master link to multiple Ethernet slaves (up to 8)

4. Install TRP-C31M

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

TRP-C31M to the LAN and serial device. A review of the switch settings and the functionality of the

LED’s are also provided.

4-1.Power Connection

The TRP-C31M has a two pins terminal block and power jack. Power can apply from either terminal

block or the power jack. It accepts 9VDC-15VDC 500mA power supply. When power is applied

PWR LED will turn and flash every one second to indicate the system is up and ready.

4-2.Ethernet Connection

Astraight-through Ethernet cable can be used to connect the MODBUS gateway to an Ethernet hub,

switch, or wall plate. A crossover Ethernet cable can be used to make a connection directly to the

NIC (Network Interface Card) on a PC or laptop.

4-3.Serial Connection

The TRP-C31M has one DB-9 male connector. The serial port is configured as a DTE (data

terminal equipment) device just as PC’s COM ports. Therefore a null modem cable is required to

make a connection between a COM port on a PC to the TRP-C31M serial port. The cable to

connect the TRP-C31M serial port to a DCE device must be straight-through.

The TRP-C31M has one serial port. The port can be configured as a Console Mode connection or

as RS-232, RS-422 or RS-485 interface to the TRP-C31M (if all of the DIP switches are in the OFF

position) using the TRP-C3XM software, via Telnet, or using the Web Server.

5.Serial Port Operational Modes

Using the TRP-C3XM Manager software, the serial port of TRP-C31M can be set to Console Mode,

Default Mode or Upgrade Mode. The serial port can be configured for RS-232, RS-422 or RS-485

operation. The TRP-C31M also can be set to Console Mode by placing all the DIP switches into the

ON position.

5-1. Console Mode

The console mode allows TRP-C31M access to the setup menu. This is the way to reconfigure the

default settings for the application. A serial connection is made between a PC COM port and the

TRP-C31M serial port by using a null modem cable. In console mode, the serial port defaults to an

RS-232 interface.

The serial port default settings are,

Server name: TRP-C31M

Serial number: Fixed

Password: Blank

DHCP: Disable

IP address: 192.168.1.1

and must be set to VT100 emulation mode. The default settings are used when the first serial port is

set to console mode regardless the actual configuration parameters are.

5-2. Upgrade Mode

The newest firmware can be upgraded to TRP-C31M using the PC’s serial port .

5-3.Default Mode

When Default Mode is selected and the Gateway Properties are updated (saved), all configuration

settings return to their default values.

5-4.RS-232 Mode

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 next Pin out for connections.

5-5.RS-422 Mode

The RS-422 mode supports 4 channels with full duplex operation for Receive, Transmit, RTS

(Request to send) and CTS (Clear to Send). The data lines are in differential pairs. Ground provides

a common mode reference. To use handshaking Flow Control must be set to RTS/CTS during

configuration. Refer to the next pin out for connections.

5-6.RS-485 Mode

The RS-485 mode supports the Transmit and Receive Channels using 2-wire half-duplex operation.

The data lines are differential pair Ground provides a common mode reference. Refer to the Pin

out table for connections.

6. TRP-C31M Software Installation

Trycom TRP-C3XM is a manager software provides user an easy way of TRP-C31M configuration

over Ethernet. User may find the software in Trycom support CD or download from Trycom web

www.trycom.com.tw. Configuring TRP-C31M to meet your LAN and application requirement is an

easy process with the available setup menu in the TRP-C3XM manager software. So It is

recommended the user install the TRP-C3XM software and do a search for all TRP-C31M over the

network. When the searching process is completed, a window will list all the on LAN devices, user

may make them available for configuration.

6-1.New Installation

The following procedures are for the TRP-C3XM Manager Software installation.

Step1. Inserting the TRP-C31M support CD in the CD-ROM, it will automatically launch the

InstallShield Wizard. To manually start the software installation, select the Start button on the

desktop. At the Run command line type D:start.exe, then select OK. The D: is the drive letter for the

CD Rom.

The InstallShield Wizard window automatically displays to begin the setup procedure.
