DIP Switch Settings
Use the device DIP switch to set the AXB-VOL3 AXlink device number. You can set it as one of
255 devices in an Axcess control system. Set the device number with the total of all ON (down)
switches. As an example, the DIP switch below defines Device 128.

Value
The device number takes effect only upon power-up. If you later change the device number, remove
and reconnect the AXlink connector to enter the new device number into memory. AMX standard
device numbers are assigned as follows:
The AXB-PCCOM emulates a touch panel when set in the panel range.
Wiring
Preparing and connecting captive wires
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.
Wiring guidelines
The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8 power
supply. The Central Controller supplies power via the AXlink cable or external 12 VDC power
supply. The maximum wiring distance between the Central Controller and interface is determined
by power consumption, supplied voltage, and the wire gauge used for the cable. The table below
lists wire sizes and maximum lengths allowable between the VOL3 and Central Controller. The
maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts available at
the Central Controller's power supply.
