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 boom
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
SmartSensor 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 nd out
which options are best suited for your application.

several contact closure cards can be daisy-chained together. However, the chain
