Connection and Wiring, Setting the Device Dip Switch

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. 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, 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.

Device DIP switch settings

Position	1	2	3	4	5	6	7	8

Value	1	2	4	8	16	32	64	128

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.
