16.4.2 P3 – RS-232 Cable Ground Pins
Some devices connected to the DB9 connector may
cause a ground fault condition on the
control/communicator. If this occurs, removing the
plug across the P3 jumper pins may clear the ground
condition.
Some devices can cause a ground fault even if the P3
jumper plug is removed.
• P3 Jumper Pins Disabled: Isolate DB9 Shield from
Data Bus Common (Black)
• P3 Jumper Pins Enabled: Connect DB9 Shield to
Data Bus Common (Black)
