INSTALLATION MANUAL
CA-ETHR-A
TCP/IP Module
1) Set the jumpers to "Direct" as shown in Figure 7. For more information on Direct
Connections, see "Jumpers" on page 17.
2) Apply 12Vdc to the terminals labeled 12V and GND on the TCP/IP module.
3) Connect a 4- to 5-pin connector cable (not supplied) from the RS-232 to RS-485
Converter (CA-A360-A) to the connector labelled SERIAL on the TCP/IP module.
4) Connect a twisted pair Ethernet wire (10BaseT) between the TCP/IP module's RJ-45
network connector and the LAN.
5) Connect the RS-232 to RS-485 Converter (CA-A360-A) to any RS-485 device.

4] JUMPERS

The CA-ETHR-A TCP/IP Module has two on-board jumpers which allow you to select whether
the communication between the TCP/IP module and a serial TTL device is null or direct.
These jumpers only affect the serial TTL connector (port 1).

Direct Connection

If you need a direct connection between the TCP/IP module and a serial TTL device,
set the jumpers as shown in Figure 7:

Null Connection

If you need a null connection between the TCP/IP module and a serial TTL device,
set the jumpers as shown in Figure 8:
