Order P/N 071-01508-0101 or 071-01508-0202 for a KA 90 Interface Adapter. The KA 90 interfaces the KLN 90B with various other avionics in an aircraft. It converts GAMA 429 output to analog in order to drive mechanical HSI/CDI devices. It also converts analog heading and HSI/CDI outputs into 429 data.

Sw. Ann. 031-00785-0768 KLN 90A Upgrade to KLN90B Approach Set If a KLN 90A is upgraded to a KLN 90B, the additional GPS CRS and GPS APR switch/annunci- ators are needed. KLN 90B with EFIS Approach Set Most EFIS systems will provide NAV/GPS switching and WPT/MSG annunciation but still require external GPS CRS and GPS APR switch/annunciators.
Page 23
031-00785-0768 NAV/GPS Switch/Annunciator Installations where the outputs from KLN 90B and an existing navigation system are switched be- tween a common indicator or HSI may require some type of annunciation. A NAV/GPS switch/an- nunciator is available that provides both the annunciation and a switch contact to energize the switching relay(s) required for the switching of the outputs.

GPS CRS, OBS/LEG Switch/Annunciator The KLN 90B may operated in either of two modes, LEG or OBS. In LEG mode, the flightplan legs will automatically sequence as determined by present position. In OBS mode, the active waypoint and inbound or outbound course will be manually selected.
TSO’d antennas have a five digit serial number. If the antenna is a non-TSO’d KA 91, P/N 071-01545-0100, and the KLN 90B is a modified KLN 90, the antenna is eligible for exchange as part of the upgrade program.

In LEG mode, the flightplan legs will automatically sequence as determined by present position. In OBS mode, the active waypoint and inbound or outbound course will be manually selected.
STC approval. 4. Pilot’s Guide The KLN 90B pilots’ guide must be placed in the aircraft in a location that is accessible to the pilot. The pilot’s guide is P/N 006-08773-0000 and the abbreviated pilot’s guide is P/N 006-08774-0000.
Honeywell warranty. In the case of the KLN 90B, installation of a KA 33, (P/N 071-4037-XX), or equivalent cooling sys- tem is required. Ram air cooling is not acceptable. For installation information on the KA 33 refer to the KA 33 installation manual, P/N 006-01069-XXXX or Installation Bulletin 258.
T-tail of the aircraft, where shadows could occur. It is recommended that there be a separation of at least 3 ft. between the KLN 90B GPS antenna and any VHF Comm antenna on the aircraft. Antenna baseplate must be level within 5 in both axes when the aircraft is in level flight.
2.3.6 ELECTRICAL INSTALLATION 2.3.6.1 General Information The KLN 90B will operate with an input voltage from 11 to 33 VDC, but the front panel lighting circuit must be wired for either +14 VDC, +28 VDC, +5 VDC, or 5 VAC depending upon the version of unit installed. Refer to the KLN 90B inter- connect diagram for wiring details.
ARINC 429 setup is for primary. If the pin is grounded, the ARINC 429 setup is for secondary. This pin is read each time the KLN 90B is turned on. This pin is used only for dual long range navigation installations when a KLN 90B is interfaced, through ARINC 429, as system #2.

Pin 39 is the Altitude Alert Audio output which is active whenever ALT ALERT is active. Z. Pin 40; A/C Power Pin 40 is the DC aircraft power input. The KLN 90B will accept from 11 VDC to 33 VDC input power. AA. Pins 41 thru 50; Gray Code Inputs Pins 41 through 50 are gray code altitude inputs from an encoding altimeter.
10. If the two values do not agree, then the KLN 90B will need to be calibrated. This is done by pressing the left cursor button and adjusting the value next to OBS CAL. A value of 100 is the default setting and represents no correction.

A. Verify that the blower is operating properly. B. Making sure that the power On/Off switch, located on the front panel of the KLN 90B, is in the "out" position (power off), plug the unit into the mounting rack and verify that the panel lighting works properly.
EFIS or CDI/HSI Interface Cycle the power on the KLN 90B which will cause the self test page to be displayed. Verify that the CDI needle, after it has settled, is indicating half scale right deflection. Verify that the TO/ FROM flag is indicating FROM.
Connect an IBM compatible laptop via PC loader kit P/N 050-03213-0000 (ref. figure 2-18). Set the KLN 90B to the Set 0 page. Put the #1 diskette into the PC. Cycle the power of the PC and follow the menu driven instructions. NOTE...
Roll Steering is dependent on ground speed to calculate and cannot be displayed on the ground in the Nav mode. However the KLN 90B will test the roll steering while on the system test page and activate all the outputs. The Roll Steering will be valid and active until you ap- prove the page.

BENDIX/KING KLN 90B Byte Data 52-54 indicated airspeed (IAS, knots) ASCII-coded decimal format (least significant digit is units), LSB first. Example: An IAS of 298 knots would be sent as "892" (38H, 39H, 32H). indicated airspeed checksum Break each decimal value into its BCD representation. Using BCD arithmetic, add the three BCD values and convert the low-order BCD digit to an ASCII-coded numeric digit.

3 through 9 shall be filled with asterisks if total fuel remaining is not available and consequently must be entered through the KLN 90B. The remaining bytes shall be defined as follows. (If valid data for a particular data item is received both on this bus and on an ARINC 429 input, the ARINC 429 data shall be used, and the RS-232 data shall be ignored.)
