(b)
Electrical connections are made through two connectors on the top of the unit. 115VAC, 28VDC and control data are connected to connector J1. The video signal is connected to connector J2.
(2)
Description The HMDU have color LCD-sections and retraction mechanisms. A retraction mechanism extends and retracts the LCD-section of a HMDU. The HMDU are turned ON or OFF individually. This is controlled through the SCU.

R (Ref. Fig. 009)
R (1) General
R
R (a) 7 tapping units are installed along each passenger-compartment
R lateral wall. Each tapping unit has an interface for a maximum of
R 2 HMDU.
R (b) Electrical connections are made through 4 connectors. The first
R tapping unit of each data-line receives the video and control
R data sent from the SCU and 115VAC through connector J2. The same
R data is connected through connector J3 to the next tapping unit
R input-connector J2. The last tapping unit ends with a termination
R plug connected to connector J3.
R (2) Function
R Video and control data sent from the SCU are connected to a related
R display unit through the tapping units. Each tapping unit has an
R 8-bit internal DIP-switch to give a unique address to the unit. This
R enables the SCU to control each HMDU individually.
