5.2 DB9 Ground Enable Pins (P1)
Some devices connected to the DB9 DTE RS-232
connector (P6) can cause a ground fault condition on
the control panel. If this occurs, removing the plug
across the P1 jumper pins can clear the ground fault
condition.
Some devices might still cause a ground
fault even if the P1 jumper plug is removed.
Refer to Figure 6 for jumper pin settings.
