AXB-REL8 Axcess Relay Controller
Connection and Wiring

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. 1o n page 1. Each device in the AXlink bus must have a unique AXlink device number.
The device can be 1 of the 255 devices in an Axcess, AXCENT, AXCENT2, or AXCENT3 system.
The device number must match the device assignment in the Axcess program. AMX assigns device
numbers into the following three segments:
! Cards 1 through 95
! Boxes 96 through 127
! Panels 128 through 255
Set the device number by setting the DEVICE DIP switch. The device number is the total of all of
the switches in the ON (down) position. The following table shows the switch numbers and their
corresponding values.
As an example, the following DIP switch (FIG.2) defines the AXB-REL8 as device number
97 (1 + 32 + 64 = 97).
Set the AXB-REL8 device number before connecting AXlink wiring. Do not install relay wiring at
this time.

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.
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.
