4.3 Communication Interface
4.3.1 Remote Contact (IBM AS/400)
The AS/400 interface is a standard feature and is available as dry switch contacts
through a DB9 male connector located on the back side of the UPS (see Section 9
for DB9 connector location). The following schematic shows the contact state and
pin assignment for each signal and the associated DB9 connector pin-out.
Notes:
1) Pin "switches" are shown in their inactive states (if battery voltage is low pin 7 will be connected to
System Common).
2) Contacts are resistive loads rated at 30 Vdc, 0.1 amp. (125VAC 3A)
3) Pin number 3 is not used.
