The System Bus (i-on EX Control Units Only)
30 50 160
The system bus carries all the data between the control unit and its expanders
and keypads. Electrically the bus is a single set of four conductive paths. Two
paths carry dc power and two carry data. Physically the bus cable can connect
the devices in either daisy-chain or star arrangements – see Figure 2.
Figure 2. Bus Layout Example
See the relevant Installation Guide for details of bus configuration, maximum
bus length and cabling type. See page for 130 detailed instructions on how add
devices to the bus. As part of programming the i-on30EX, i-on50EX and i-
on160EX you will need to understand how devices are addressed, and how to
add and delete them correctly.
Device Addressing on the Bus
Each device on the bus has a unique address. The device obtains this address
from the control unit, either during the commissioning stage of a new
installation, or at some later date under control of the Installer Menu when the
installer adds the device. Once the device has obtained a bus address, the
device stores that address in non-volatile memory.
During subsequent programming at the control unit the Installer also assigns
other information to each bus device, for example allocating them to partitions,
or programming the zone types and attributes of any zones attached to
expanders. The control unit stores this information within itself (NOT within the
bus device).
