11.2 Normal Operation
For normal operation, turn the system power on. The power LED should be on. On the
master controller the network LED should be blinking, indicating it is communicating
with other PXL-250 controllers on the network. If this is a single controller network,
the LED will blink for several minutes until it determines that there are no other
controllers with which to communicate, then it will turn off. The address programmed
into the controller will flash on the address display LEDs for 2 seconds.
If the optional Alpha/Numeric Plug-in Display has been installed, it will display a Keri
Systems header and the controller's address (see Figure 11-3).

11.3 Viewing Controller Addresses
To view a controller's address, click S1 (see Figure 9-1 on page 39 and Figure 11-2 on
page 93). The controller's address appears on the address display for 2 to 3 seconds.
11.4 Setting Controller Addresses
To set the desired operating address for the controller, turn the controller's power off.
Verify JP3 is not installed (see Figure 9-1 on page 39 and Figure 11-2 on page 93 – if
JP3 is installed, the controller RAM will be reset when the power is turned on). Hold
the S1 Address and Diagnostics Button down and turn the controller's power on. The
beeper for the reader attached to the controller will beep as power comes on followed
by a beep-beep indicating the controller's firmware has entered the address setting
mode. Release S1. The address display LEDs then become active and the controller's
address can be set. If an Alpha/Numeric Display (LCD-1) is connected to the
controller, "Address Change" will appear on the display. The address range is from 1
to 128 (the Master Controller must always be set to address 1).
