The Click 200 contains three terminal connectors on both the top and the bottom of the

module (see Figure 2.3). The terminal connectors are removable and are red-keyed, allow-

ing the connector to plug into only one specific jack. This both simplifies the wiring process

and reduces the possibility of wiring errors.

The back four terminals consist of one +DC power, -DC and two surge ground connec-

tions; the middle four terminals are for RS-485 communication and consist of a +485 con-

nection, 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.
