TCP/IP Module

3] HARDWARE CONNECTIONS

The following sections provide an overview of the TCP/IP module and details on how to
connect it between a serial device and a LAN.
A special connection method is required when confi guring the module through its serial port.
Refer to "Confi guring Via Serial Port" on page 5.

Connecting Between LAN and RS-232 Device

This connection method enables you to connect the TCP/IP module to a serial device's DB-9
connector (RS-232 serial port). For example, you can connect to the serial port of a Centaur
CT-V900-A controller. The standard connection requires the use of a DB-9 to modular phone
jack cable. Refer to Figure 5 below and to the instructions that follow:
1) Apply 12Vdc to the terminals labeled 12V and GND on the
TCP/IP module.
2) Connect the DB-9 to modular phone jack cable between the modular phone jack on the
TCP/IP module and the serial device's DB-9 connector (refer to next Table).
3) Connect a twisted pair Ethernet wire (10BaseT) between the TCP/IP module's RJ-45
