Port Connected to
P2 CU PCBA
P3, 5, 6 Not Used
P4 ALI or RCI PCBA
P11 - 14 Channel PCBA positions 1 through 4
P21 PSU, connector 1
P22 LED PCBA in cover
P23 LNA/UL
P24 LNA/DL
P25 Expansion output port to cover circuitry. Only in cabinets.
P26 Expansion input port to cover circuitry. Used in equipped high covers.
P27 Auxiliary Port (8-pin male) - Pins 2 and 3 must always be interconnected to provide
the CU and ALI/RCI PCBAs with voltage. If there is no cable connected, pins 2 and 3
must be interconnected with a jumper.
P28 Door switch port - Normally, alarm input AI4 is used for door opening alarm EAL4
which is arranged using an optional door switch. Signal AI4 and AIC are thus avail-
able also in the P28 connector, to which the door switch is connected. The EAL4 door
switch alarm is activated 10 – 30 seconds after the cover has been opened.
P29 Power to FON
P31 RS-232 PC Port (9-pin D-sub female) - Used for local PC communication.
P32 RS-232 Modem port (9-pin D-sub male)
P33 External Alarm Port (15-pin D-sub female) - Used for external alarm sensors and
alarm equipment. Four alarm inputs, EAL1 – EAL4, and two alarm outputs.
