5. Connect the alarm output cable, if used.
Route this cable through the board's cable clamp
and connect its wires to the P3 connector on the I/O
board as follows:
P3 Connector (Alarm Outputs)
Pin Color Designation
1 N/A* 12Vdc (100 mA max.)
2 N/A* 12Vdc (100 mA max.)
3 N/A* Output P0 (40mA sync max.)
4 N/A* Output P1 (40mA sync max.)
5 N/A* Output P2 (40mA sync max.)
6 N/A* Output P3 (40mA sync max.)
7 N/A* Ground
8 N/A* Ground
6. Connect ac wires.
Connect the following wires of the data/power
cable from the outdoor interface board to the P7
connector on the I/O board as follows:
P7 Connector (AC In)
Pin Color Designation
1 Black AC
2 Red Ground
3 White AC
Referring to Figure 3-5:
7. Connect power to the base.
8. Observe green power and yellow communi-
cation LEDs on the other side of the I/O
board.
The green LED should be on steady. The yellow LED
should flash.
9. Test the communication lines.
If using RS422 communications, press and hold the
pushbutton and observe nearby red and green
LEDs. These LEDs indicate the following:
Constant green with blinking red. Indicates
the RS422 line is correctly wired.
Constant green with no red. Indicates that
RS422 "Data In" – is shorted to ground.
Constant red with blinking green. Indicates
that the "Data In" + and – wires are reversed.
Blinking red, green off. Indicates that RS422
"Data In" + is shorted to ground.
Both LEDs off. Indicates that "Data In" + or –
wires are shorted or open.

10. Reattach the I/O Board (Figure 3-6).
a. If wiring is OK, then pull excess cable up through
access hole.
b. Aligning the ground pad with the finger contact
above, insert the board under the retaining
fingers. Board is keyed; it will only fit into the
base one way. Press on board to snap it in place.
c. Gently remove the dust cover from the 32-pin
connector and inspect the spring finger contacts.
For reliable connections, all contacts should be at
least 2mm above the surface of the connector.

Keep the dust cover for use
should you have to ship the base
and I/O board back to the
manufacturer.
