Connecting Between LAN and RS-485 Device

This connection method enables you to connect the TCP/IP module to a device that uses the
RS-485 standard. For example, you can connect to another CA-A360-A RS-232 to RS-485
Converter to expand the distance between the TCP/IP module and the serial device or to
connect the TCP/IP module to a device using the RS-485 communication standard. Refer to
Figure 6 page 16 and to the instructions that follow:
If you apply 12Vdc to the TCP/IP module, do not connect the +12V and GND terminals on the CA-
A360-A.
