6. Ensure no excess cable is left inside the
enclosure and tighten cord grips.
7. Reconnect power to the indicator.
8. Use the DIG I/O menu to conÞgure digital I/O

The 920i automatically recognizes all installed option
cards when the unit is powered on. No hardware-speciÞc
conÞguration is required to identify the newly-installed
card to the system.
A digital I/O expansion card installed at connector J5
on the CPU board is conÞgured as slot 1; a card
installed at connector J6 is conÞgured as slot 2.
