designed for connection to a remote display.
For indicators housed in a Stainless Steel enclosure, COM1 is realized in J6 while COM2 is

2.2.3 CONNECTING THE POWER SUPPLY
1. The indicator ships standard with an internal AC to DC adapter. Simply plug the AC line
cord into a standard wall outlet.

adapter into the indicator’s DC Power Jack first, and then plug into a standard wall
outlet.
Make sure that the AC voltage appearing at the wall outlet matches the
input voltage marked on the AC adapter.
