W-1: Com Port 1 & 2 (RS-232) Wiring
Com Port 1 and Com Port 2 have very similar pin layouts; the only difference is that Port 2 has
a RTS signal output, which Port 1 does not have.
NOTE: Both Com ports can provide 5VDC; however, the 5VDC power can be used only for the C-more
Micro-Graphic panel. AutomationDirect does not guarantee that the CLICK PLC will work correctly when
any other device uses 5VDC from these Com ports. Please also remember these Com ports can provide
enough power only for one C-more Micro-Graphic panel. If you are going to connect a C-more Micro-
Graphic panel to each Com port (2 panels in total), you must obtain power from a separate 5VDC power
source for the second C-more Micro-Graphic panel.
Wiring Strategy
The following pages cover five case scenarios for connecting com ports 1 or 2:
Case 1: Connect Com Port 1 or 2 to a PC.
Case 2: Connect Com Port 1 or 2 to another CLICK PLC.
Case 3: Connect Com Port 2 to a C-more or C-more Micro-Graphic panel.
Case 4: Connect Com Port 2 to an RS-232 port on another device.
Case 5: Connect Com Port 1 or 2 to an RS-422 or RS485 port on another device(s).
