Wiring Communication
After wiring the sensor cable into the PROTECTED side of the Click 200 in the pole
mount cabinet, two isolated serial connections are available. The sensor’s native RS-232
port is available via the DB-9 connector on the faceplate.
In addition, the sensor’s native RS-485 connection is available in the pole mount cabinet
via the following three ports on the Click 200:
˽
Screw terminals on the bottom
˽
RJ-11 connector on the faceplate
˽
T-bus backplane
Note
The Click 200 does not convert RS-232 communication to RS-485. It simply provides
surge protection for these two independent connections.
One common way to connect communications back to a main cabinet is to use a Smart-
Sensor cable as your homerun cable. See Appendix C for information about maximum
cable lengths for wired communication. Wavetronix Click products facilitate a wide variety
of additional wired and wireless communication options. Contact a Wavetronix-authorized
technical representative to find out which options are best suited for your application.

cards can be daisy-chained together. However, the chain should not be connected until each
