Connect a Programming Terminal to the Controller Via RS-232 Connections
Use an RS-232 cable to connect your CompactLogix controller to your
programming terminal. You can use either of the following RS-232 cables:
• 1747-CP3
• 1756-CP3
The figure shows the RS-232 cable connections. The 1747-CP3 or 1756-CP3
cable must be shielded and tied to the connector housing.
WARNING
If you connect or disconnect the serial cable with power applied to this module
or the serial device on the other end of the cable, an electrical arc can occur.
This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
