E. Programming and Test Panel
(1) Description
(Ref. Fig. 031)
(a)
General The Programming and Test Panel (PTP) 110RH is installed in the rear wall of lavatory A. It is located at the FWD attendant station, behind a hinged access door next to the installed FWD attendant panel. For correct CIDS operation, the Cabin Assignment Module (CAM) must be installed in the socked. This is provided on the panel front face. The PTP enables the forward attendant and other personnel to extensively test and re-program the CIDS.
(b)
Function and Layout
The functions of the PTP are as follows:
-
To program the CIDS properties and cabin layout information into the CIDS directors, which are copied from the CAM.
-
To manually down-load the alternative CAM layout into the directors and cause this layout to be down-loaded automatically in subsequent CIDS start-ups. To onboard re-program:
-CAM data,
-activation of the provisioned CIDS extra functions,
-change cabin layout,
-implement cabin zoning.
-
To monitor the failure status of the CIDS and some of the connected systems.
-
To examine the fault data held in the director BITE memory.

-To activate CIDS component tests and the readout of the
results.
The PTP has an alphanumeric display with four rows of twenty characters. The display is used to present messages, test results and selection menus. At either end of each display row are blank keys. They are labelled on the display with '<' or '>' characters. A conventional keypad is provided for entry of numerical data. One membrane switch switches the display on and two membrane switches test the emergency lights. Three indicator lamps are provided for emergency lighting system/testing indications. The Cabin Assignment Module (CAM) 115RH plugs into a socket on the front face of the panel.
(c)
Architecture An ARINC 429 interface handles all communications between the PTP and the directors. A single output is connected to both directors. Two separate buffered inputs are provided, one for each director. The PTP power supply derives all the internal voltages from one 28 V DC input. The display is automatically switched off after ten minutes of panel nonoperation (i.e. no key pressed). The CAM is interfaced within the PTP to allow the panel to read, and also to modify the CAM data. The PTP is able to transfer any of the CAMs internal layouts to the director. BITE is incorporated into all the circuits of the PTP.
(d)
Cabin Assignment Module The Cabin Assignment Module (CAM) 115RH defines all of the modifiable system properties and layout information for the CIDS. It contains the possibility for four cabin layouts, (LAYOUT 1 - 3 and LAYOUT M.
