Quickly double clicking S1 toggles between increasing and decreasing the controller
address. The top LED character will display either a "+" or a "-" to show which
direction is active. A single click of S1 changes the controller address by 1. If you're at
address 128, a +1 click will roll the address over to 1; conversely, if you're at address 1
a -1 click will roll the address over to 128. Holding S1 down rapidly scrolls through
the addresses. Click through the address range until the desired address is displayed by
the address display LEDs.
After the new address has been set, you must wait approximately 30 seconds. There is
a timer in the controller's firmware that assumes that after 30 seconds of inactivity (no
address clicks), the entered address is the desired address for that controller. When the
30-second timer expires, there will be a beep-beep (from the “A-Door” reader attached
to the controller) indicating the controller has recognized and accepted the new
address and the address LEDs will turn off. If an Alpha/Numeric Display (LCD-1) is
connected to the controller, "UNIT ##" will appear on the display (where ## is the
controller's address - see Figure 11-3 on page 94).
11.5 Master Controller Requirements
The master controller must be set to address 1 so that all slave controllers on the access
control network can identify the master controller. For the master controller to
correctly identify all slave controllers on the network, the Auto-Configuration routine
within the Doors program must be run. This instructs the master controller to poll all
other controllers on the network for addresses and configuration information (the
Auto-Configuration button is found under the Setup/System/controllers tab in the
Doors program).
