Wavetronix Click 201 - RS-232 Communication

24 CHAPTER 3  WIRING THE DEVICES
RS-232 Communication
Most Click devices also feature RS-232 communication capabilities. ese 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 dierent cable or wiring system, the colors of the wires used
will be dierent.
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.
