The Click! 200 contains three terminal connectors on both the top and the
boom of the module (see Figure 2.3). The terminal connectors are removable
and are red-keyed, allowing the connector to plug into only one specic jack.
This both simplies the wiring process and reduces the possibility of wiring
errors.
The back four terminals consist of one +DC power, -DC and two surge ground
connections; the middle four terminals are for RS-485 communication and
consist of a +485 connection, a -485 connection, an RS-232 ground connection
and a surge ground connection; the front four terminals are for RS-232
communication and consist of TD, RD, CTS and RTS.
