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.
