CHAPTER 3 WIRING THE DEVICES

RS-232 Communication

Most Click devices also feature RS-232 communication capabilities. These modules will

convert the RS-485 communication moving to and from the T-bus to RS-232. See below for

how to connect RS-232 to a laptop.

Several modules also have RS-232 screw terminals.

Note

The steps in this section are specifically for use with a Wavetronix SmartSensor ca-
ble. If you are using a different cable or wiring system, the colors of the wires used
will be different.

To use, follow the steps below:
1 Connect the RTS (orange) wire from the cable or terminal block to the RTS screw ter-

minal on the protected side of the Click device (see Figure 3.4).

2 Connect the CTS (brown) wire to the CTS terminal on the protected side of the Click

device.

3 Connect the TD (yellow) wire to the TD terminal on the protected side of the Click

device.

4 Connect the RD (purple) wire to the RD terminal on the protected side of the Click

device.

5 Connect the RS-232 drain wire to a GND terminal on the protected side of the screw

terminal blocks.
