Passenger Display and Top Display Board
The 2 x 16 character display is a non-repairable item and is soldered
into the top display board. The top display board contains the smart
card LED indicators (red, amber, green). The interface to the printer
board is via ribbon cable connection from (PL1) on the top display
board. The display backlight can be dimmed under software control
to 16 different levels.

Card Reader Antenna Board
The antenna PCB is secured to the underside of the hinged lid and is
protected by a black plastic cover. The antenna board circuitry senses
the presence of a smart card and reads the data on it. The data is
then passed to the console control PCB via the coaxial RF cable
assembly (SKT1). Adjustment of the antenna should only be
performed using specialist equipment.
