R R R R R (Ref. Fig. 015) Each DEU type A is controlled by the active director. The DEUs type A are connected to one of the two data bus top lines via connection boxes. One top line is installed along each A/C side. Every DEU type A on one A/C side is connected to the same top line. Every connection box includes coding switches which give each DEU type A its own address. The last connection box, connected to a top line, includes also a termination resistor for impedance matching and is therefore called a termination box.
R (a) The DEU type A has direct interfaces to the: - Director, - Passenger Interface and Supply Adapters (PISA), - Stand Alone Passenger Interface and Supply Adapters (StA PISA) (Ref. 33-27-00), - Ballast units, - Loudspeakers, - NS, FSB and RTS signs.
R R R (b) The DEU type A has interfaces via PISA or StA PISA to the: - Loudspeakers, - Reading lights, - Attendant work lights, - Seatrow identifiers, - Passenger call/reset pushbuttons, - Passenger call lights, - NS, FSB and RTS signs.

R R R R R Each DEU type B is controlled by the active director. The DEUs type B are connected to one of the two data bus middle lines through connection boxes. The middle lines are installed along each A/C side. The middle line at one A/C side (left and right) connects every DEU type B on the same side of the A/C. Every connection box includes coding switches which give each DEU type B its own address. The last connection box connected to a middle line includes also a termination resistor for impedance matching and is therefore called termination box.
R (a) The DEU type B has data bus interfaces to the: - Director, - Additional Attendant Panel (AAP), - Attendant Indication Panel (AIP), - Emergency Power Supply Unit (EPSU), - Lavatory smoke detector.
