Installation
The BLF/CGM mounts on the back of the attendant console and is held on
using snapfits and two screws. It is connected to the console using a 15-way
connector that is located on the keyboard printed circuit board (PCB). This
connector is accessed through a rectangular knockout section located
underneath the casing overhang at the Meridian logo location (see Figure 54).
For more information on the features and operation of the BLF/CGM, refer
to the Busy Lamp Field/Console Graphics Module User Guide.
Power requirements
The BLF/CGM obtains its power through the attendant console.
An external floating 16 V DC (300 mA) power supply (transformer—
A0367601) must be cabled in at the local cross-connect terminal at a
maximum of 115 ft. (35 m) from the attendant console when the BLF/CGM
is installed. This provides backlighting for the BLF/CGM.
