AMX AXP-CPI16 manual Setting the AXlink Device Number, Connecting the Two 20-pin Headers

Setting the AXlink Device Number

The 8-position device DIP switch defines the AXP-CPI16 as an AXlink device. It can be one of 255 devices in the Axcess Control System. Set the device number with the total value of all ON (down) positions. As an example, the device DIP switch shown below defines device number 129 (1+128=129).

Position	1	2	3	4	5	6	7	8	OFF
Value	1	2	4	8	16	32	64	128	ON	1 2 3 4 5 6 7 8
									ON

AMX standard device numbers are assigned as follows:

Cards are 1 through 25.

Boxes are 96 through 127.

Panels are 128 through 255.

1.Strip 0.25 inch of wire insulation off all wires.

2.Insert each wire into the appropriate opening on the connector according to the wiring diagrams and connector types described in this section.

3.Tighten the screws to secure the wires. Do not tighten the screws excessively; doing so may strip the threads and damage the connector.

Connecting the Two 20-pin Headers

The following chart notes the pinouts of the two 20-pin headers for P2 and P3.
