Setting The Axlink Device Number; Preparing/Connecting Captive Wires; Connecting The Two 20-Pin Headers - AMX 16-Channel Custom Panel Interface AXP-CPI16 Operation/Reference Manual

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).
AMX standard device numbers are assigned as follows:
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
