The KI-209A does not have an OBS resolver inside the indicator to provide selected course information to the GPS. Instead, it has a Sine/Cosine potentiometer. To see the Sine/Cosine potentiometer and properly calibrate to it, it requires more than the +/- 10 degrees of adjustment that a KLN-90B has. The KLN-89B and KLN-900 has +/- 180 degrees of adjustment. Therefore, the KI-208A and KI-209A are limited to the KLN 89B and KLN 900.

Yes, the Bendix/King KI-209A will connect with the Garmin GPS-155XL IFR GPS and the GNC-300XL IFR GPS/Comm to provide Left/Right and To/From Deviation Indications. However, to properly connect the GPS-155XL and GNC-300XL to the KI-209A indicator, the installer must add two 10 kohm, 1/4 watt resistors between the connection. One resistor is placed in between connector P1 pins 35 and 4, and the other resistor between connector P1 pins 37 and 4.

No. The KI-208 and KI-209 indicators contain an internal VOR/LOC converter. These indicators do not provide any means to bypass the converter for a direct meter movement connection. The KI-208A and KI-209A include a relay that provides the means to bypass the converter for GPS deviation indication.

No, the KI-208A and KI-209A use a 50 pin rectangular Positronic connector. The KI-208 and KI-209 use an older style, 12 pin square Burndy connector.

None, they represent the same unit. Original King Radio part numbers were 9 digits. For example, 066-3056-01. During the Bendix and King merger (i.e. Bendix/King), a new part numbering system was created that converted these 9 digit part numbers to 12 digits. Therefore, 066-3056-01 became 066-03056-0001. Despite this numbering change, units that were originally from the King Radio design still have the 9 digit part number format on the unit dataplate. The 12 digit format for King units appears to be used for catalog and internal Honeywell purposes only. Therefore, any unit that has a zero in its third to last number (i.e. XXX-XXXX-X0XX) has a 9 digit part number (i.e. XXX-XXXX-XXX) on its dataplate / ID Plate.

In January 1989 Bendix/King changed from a nine digit to a twelve digit part numbering system. The new, larger 12 digit numbers allowed for the inclusion of software version into the last two digits of the part number for certain units in which software changed frequently such as EFIS and TCAS processors. Therefore, the two digits immediately preceding the software version indicate the hardware version of the unit.

Different software versions imply different operational features and/or interface capabilities and software modifications imply software repairs (bug fixes) to insure proper operation of these features and interfaces. Software version upgrades frequently require hardware modifications to the unit. Such hardware modifications accompanying software version upgrades do not necessarily change the hardware version of the unit.
