BendixKing KLX 135 - Pilots Guide - Manual (Page 18)

The data base is updated by means of a 3.5-inch diskette supplied by
AlliedSignal and an IBM-compatible personal computer. This method
does not have to involve removing the KLX 135 from the aircraft’s
instrument panel. A jack, usually mounted in the aircraft’s instrument
panel, provides a means of interfacing the KLX 135 with the comput-
er via an interface cable. The diskettes are not returned to
AlliedSignal.
Every 28 days, AlliedSignal receives new NavData information from
Jeppesen Sanderson. This information is processed and down-
loaded onto diskettes. AlliedSignal makes the update service
available to you in a choice of several subscription or random update
programs. See
section 2.6 for details on these programs.
NOTE: AlliedSignal sends the update so that it arrives prior to the
next effective date. The new update may be installed any time prior
to the effective date and the KLX 135 will use the previous data up to
the effective date and automatically begin using the new data on the
effective date.
In order to use the update program you must have access to a com-
puter having a disk drive capable utilizing 3.5-inch 1.44 megabyte
high density diskettes. 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. The data loader jack is included with the KLX 135
installation kit and is typically installed in the aircraft’s instrument
panel.
CAUTION: The data base must be updated only while the air-
craft is on the ground. The KLX 135 does not perform any
navigation function while the data base is being updated. Since
a data base update takes approximately 10 minutes it is a good
idea to turn off all electrical equipment on the aircraft except for
the KLX 135 to avoid running down the aircraft battery.
NOTE: The diskettes sent to you can only be used to update one
KLX 135, 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 KLX 135 being used is uploaded to the
diskettes. These diskettes may be used in this specific KLX 135 an
unlimited number of times which could be required if you switch back
and forth between the North American and International data bases
during one update cycle. These diskettes may not, however, be used
to update other KLX 135s. This update protection ensures that
Jeppesen Sanderson is properly compensated for the use of their
NavData.
