Configuration Switch
The addressing of the Reader Expander allows up to 128 devices to be connected to the system controller. The
'CONFIG' configuration DIP switch allows each Reader Expander to have a unique address.
6.1
Address Configuration
The settings of the switch positions (1 to 7) determine the address assigned to the Reader Expander, a value
from 1 to 128. When setting an address the Reader Expander must be powered down and restarted for the
new address to take effect. When changing the address the Reader Expander will automatically default the
internal configuration and require a network update. See the Protege System Reference Manual for information
on performing a module update.

Reader Expander CONFIG Switch Functions
The device address is determined by adding the value of each switch (1 to 7) that is set in the ON position and
then adding 1 to this value. In the following example, the device address is determined by performing the
addition (64 + 8 + 4 + 2) + 1 = 079. Setting all address switches to OFF results in the default address of 001.
