(6) Power/CAN Extension Cable Assembly

(a) The oxygen valve open duration can vary depending on the cabin pressure altitude and the manifold pressure and ambient temperature adjustments. Cabin pressure altitude information is received on the CAN bus via the power/CAN extension cable assembly. Local pressure and ambient temperature adjustments are calculated by the oxygen controller assemblies.

C. While the aircraft is in maintenance mode, certain BIT checks can be signaled to the central
maintenance computer by the pulse controller module on the oxygen panel assembly. The BIT
check signals give an indication when:
(1) The initiator circuitry has continuity.
(2) The door latch has continuity.
(3) Power is available to the pulse controller module.
