Front panel assembly The front panel assembly contains identification and modification status labels, status LEDs, a latched door for access to a SELF-TEST pushbutton switch, a HEADPHONE jack, a RS232 test connector (P1), and a Personal Computing Memory Card Interface Adapter (PCMCIA) interface and status LEDs. There is also a handle for ease of carrying and installation/removal, and a hold-down hook for securing at installation.
(c)
Chassis The chassis is welded aluminum, composed of a top and bottom and two sides. It provides slots for CCA and space for the front and rear panel assemblies.
(d)
PCMCIA interface The standard Type II PCMCIA interface provided at the front panel allows for both the uploading and downloading of internal Enhanced GPWC information. Control of the upload/download process is accomplished by insertion of the PCMCIA card into the front panel access. Four LEDs are provided for PCMCIA interface operation. The PCMCIA card does not remain installed during normal Enhanced GPWC operation, and is not intended as an on-line/inflight storage medium.
(e)
Front connector A 15-pin (double density, D-Sub) test connector is located on the front panel, which provides for connection to either a CRT terminal or a PC. This connector provides the following interfaces:

1 Three-wire serial interface, compatible with RS232
_ This port can be used to access internal data from the Enhanced GPWC for both bench simulation and aircraft testing. Unit configuration and flight history can also be accessed. This port can also be used to upload software and data bases.
2 ARINC 429/422/423 data loader interface
_ This port can be used to upload software and data bases. System power is provided on two of the pins for data loader use. The Enhanced GPWC front connector pins are listed in the table below (N/U means Not Used):
