1. Disconnect power to the display.
2. Open the display and lift the LED module panel to access the interior

components.

Display Addressing

Before a display can be run in a sign network, it must have an
address. The display address can be set using “DIP” switches
located on a PC board known as the MDC. The MDC is the circuit
card mounted on the left end of the controller board.

Locate the DIP switches on the MDC. They should be on the
bottom end of the card. Refer to

Figure 35

for a picture of the DIP

switches.

When replacing a controller board, be sure to set the DIP switches
to the same address configuration as the defective controller. The
DIP switches follow standard binary code.

Note: By setting the DIP switches to address 0 (flip all the switches
up or toward the numbers on the circuit board), a test mode can be
activated. The display’s power must be turn off and then back on to
recognize test mode, or any address change.
