box, and you want to access that sensor from a main traffic cabinet or from the traffic opera-
tions center, you will need some kind of communication between the two spots: either with
the homerun cable, which can carry both RS-232 and RS-485 communications, or by using
a Wavetronix Click communication device.
Wavetronix has a variety of wired and wireless communication devices, such as the Click
301 serial to Ethernet converter, which lets you communicate with the sensor via Ethernet,
or the Click 400, which is a 900 MHz radio that communicates wirelessly with other radios.
See the Click Catalog, Click Series User Guide, or ITS Designer Training Guide for more
information.
The Click 200 has several ports for other methods of communication. The faceplate has a
DB-9 port you could connect to for RS-232 communication. There are also several RS-485
connections:
˽ T-bus backplane: puts RS-485 on the T-bus. Because the Click 200 is connected to the
sensor, this T-bus connection means the sensor, the Click 200, and any other device on
the T-bus all communicate with each other.
˽ RJ-11 connector on the faceplate for connecting to contact closure devices, if desired.
Note
The Click 200 does not convert RS-232 communication to RS-485. It simply provides
surge protection for these two independent connections.
