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
A straight-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.
