X-BUS Addressing

Expanders, keypads and subsequent zones may be configured, located and monitored, with the steps provided in this section. X-BUS settings such as type, communication times and retries are also accessed within this menu.

The figures below show the location of the rotary switches, and each rotary switch with an arrow symbol pointing to a number for identification (that is, 3, 8). The right switch is the first unit digit and the left switch is the 10s digit. The expander in the figure below is identified as 38.

Rotary switches

Number	Description
1	Rotary switches identifying expander as 38.

For a system with automatic addressing, expanders and keypads belong to the same numbering sequence. For example, expanders and keypads are automatically numbered 01, 02, 03, etc., by the controller in the order in which they are detected, for example, its relevant location to controller. In this configuration, zones are allocated to each input expander.

Automatically addressed expanders are not supported by SPC41xx.
