Setting the DEVICE Dip Switch
The eight-position Device DIP switch is located on the front panel of the AXB-REL8 as shown in
FIG. 1 on page 1. Each device in the AXlink bus must have a unique AXlink device number.
If you later change the device number, remove and reconnect the AXlink connector.
This enters the new device number into memory. The device number takes effect only
on power-up.
The device can be 1 of the 255 devices in an Axcess, AXCENT, AXCENT
The device number must match the device assignment in the Axcess program. AMX assigns device
numbers into the following three segments:

Wiring Requirements
The AXB-REL8 uses a four-pin AXlink Central Controller connector for power and data. If the
distance between the AXB-REL8 and the Central Controller exceeds power consumption limits,
you must connect an optional 12 VDC power supply. Refer to the following section for more
information.
