2.4.1. COMPUTER UPDATING OF THE DATABASE USING
DISKETTES (ORS 02 AND HIGHER UNITS ONLY)
Update information is sent to you on 3.5” disks. In order to use the update
program you must have access to a computer having a disk drive capable
utilizing 3.5-inch 1.44 megabyte high density diskettes. This computer also
needs to have an available COM 1 or COM 2 serial port. If you wish to
perform updates in the cockpit, an optional PC Interface kit must be used.
Included in the kit is an interface cable that plugs into both the computer
and into the data loader jack located on the KLN 94 front panel.
CAUTION: The database must be updated only while the aircraft is
on the ground. The KLN 94 does not perform any navigation func-
tion while the database is being updated. Since a database update
takes approximately 8 minutes it is a good idea to turn off all electri-
cal equipment on the aircraft except for the KLN 94 to avoid running
down the aircraft battery.
NOTE: The diskettes sent to you can only be used to update one KLN 94,
although they can update that specific unit numerous times. The first time
the diskettes are used in an update operation, a unique identification code
from the KLN 94 being used is uploaded to the diskettes. These diskettes
may be used in this specific KLN 94 an unlimited number of times which
could be required if you switch back and forth between the Americas,
Atlantic, and Pacific databases during one update cycle. These diskettes
may not, however, be used to update other KLN 94s. This update protec-
tion ensures that Jeppesen Sanderson is properly compensated for the
use of their NavData™.
To update the KLN 94 database by computer using diskettes:
1. Plug the 9 pin female connector end of the interface cable into a COM
serial port of the computer. If the computer has COM 1 and COM 2
serial ports, either may be used.
2. If you are using the PC interface kit in the cockpit, plug the other end
of the interface cable (3 conductor male connector) into the data
loader jack that is located on the upper left corner of the KLN 94 front
panel.
3. Insert the diskette into the computer’s disk drive. Turn on the comput-
er being used for the database update. The program on the disk will
automatically “boot” (load) and the computer screen will display
“Ready” when the computer is ready to continue with the database
update operation.
