R **ON A/C 105-105,
A. Enhanced GPWC
(1) External descrition (Ref. Fig. 007) The Enhanced GPWC is packaged in a 2 MCU ARINC 600-6 form factor enclosure. The enclosure of the unit is painted with a blue semi-gloss coating, except for the bottom, which is unpainted. The computer is composed of the following subassemblies:
-rear panel assembly,
-front panel assembly,
-chassis,
-PCMCIA interface,
-front connector.

(a) Rear panel assembly The rear panel assembly contains a 2 MCU ARINC 600-6 form aircraft interface connector. The top and middle shells contain all interface signals. Power interface is in the bottom shell, isolated from interface signals. Connector index pin coding is orientation "08" or "10" in accordance with ARINC 723-1 recommendations for GPWS. The rear panel assembly also contains the interconnection between the aircraft interface connector and the internal interface Circuit Card Assembly (CCA), A5, and the Backplane CCA, A4, which provide all internal electrical interconnects between CCAs and other circuitry. The Enhanced GPWC pins are listed in the table below (N/U means Not Used):
---------------------------------------------------------|LRU Con |Pin| Description | ---------------------------------------------------------
| MIDDLE | 6A| 429 INPUT 1(A) ADIRU1 BUS IR (A) |
| MIDDLE | 6B| 429 INPUT 1(B) ADIRU1 BUS IR (B) |
| TOP | 9A| 429 INPUT 10(A) CFDIU (A) |
