applied, should be ignored since the EGPWC automatically handles the application and removal
of PCMCIA card power.
(4) While the loading is in progress, the IN PROG LED on the Smart Card remains ON and the
COMPUTER OK LED on the EGPWC is OFF.
(5) When loading is complete the XFER COMP LED on the Smart Card turns ON.
(6) Remove the PCMCIA card from the Smart Card slot.
(7) After approximately 15 seconds the COMPUTER OK LED comes ON to indicate that the contents
of the PCMCIA card were successfully transferred.

B. Loading the PCMCIA Card Data with Computer Mounted on the Bench
(1) Locate a 28 VDC Power Supply with a minimum supply current of 2 amps.
(2) With the Power Supply turned OFF, connect the Power Supply to the J1 connector of the EGPWC
as follows (pin J1-53 is connected to chassis ground internally and does not need to be ground in
aircraft wiring):
J1 connector Pin Pin Nomenclature
J1-40, J1-60 28 VDC (+)
J1-41, J1-61 28 VDC (-)
J1-42, J1-53 Chassis GND
Pins J1-42 and J1-53 are both connected to chassis ground internally. It is not necessary to tie them
both to ground in the aircraft wiring. Pin J1-53 was made available to provide a convenient way to
supply a ground to external equipment. If the OAT probe is not present, nothing needs to be tied to J1-
53.
(3) Connect the Smart Cable (Honeywell PN 951-0386-001) to the EGPWC J3 connector.
(4) Turn the Power Supply ON and that the COMPUTER OK LED on the EGPWC front panel is on.
(5) Insert the PCMCIA card into the Smart Cable PCMCIA card slot.
NOTE: Precautionary notes on the PCMCIA card, regarding insertion and/or removal while power is
applied, should be ignored since the EGPWC automatically handles the application and removal
of PCMCIA card power.
(6) While the loading is in progress, the IN PROG LED on the Smart Card remains ON and the
COMPUTER OK LED on the EGPWC is OFF.
