BENDIX/KING KLN 90B
Page 1-14 10521I05.TDC Rev 5, April/2003
Functions of the -0101 include converting 3-wire heading sources to ARINC 429, convert-
ing the resolver output of a non-driven HSI to ARINC 429 so that the KLN 90B can read
the selected course from the HSI, converting binary ARINC 429 data to BCD ARINC 429,
and converting low speed ARINC 429 to high speed ARINC 429. Functions of the 0201/
0202 include all of the functions of the -0101 plus converting ARINC 429 bearing outputs
from the KLN 90B to 3-wire XYZ RMI and 4-wire sin/cos OBI formats, converting ARINC
429 distance information to ARINC 561/568 6-wire format, providing interface with Collins
EHSI 74 and EFIS 85/85A/86A/86B/86C, and converting ARINC 429 roll steering data to
an analog format.
B. PC Interface Kit
To load the database from a personal computer via diskettes, order interface kit P/N 050-
03213-0000. The kit contains a ready to use cable which connects between the aircraft
connector and the computer’s 9 pin or 25 pin serial connector.
The database may be loaded directly from the PC to the KLN 90B installed in an aircraft,
or the PC may be used to update the KLN 90B while it is installed in a KCC 90 (refer to
section 2.4.4.11 and Figure 2-18 for details) or Commander 2000K from Lone Star Avion-
ics
phone (817)548-7768.
Laptop computers used to load the data base require the following:
1. IBM compatibility
2. An available Com 1 or Com 2 serial port
3. A 3.5" high density diskette drive
NOTE
Not all laptops conform to the above requirements. If
there is uncertainty relating to this, contact Honeywell
Product Services by telephoning (913) 782-0600.
C. Annunciators and Switch/Annunciators
(Refer to I.B. 363 for additional information pertaining to switch/annunciators for GPS sys-
tems)
The devices shown below are Eaton 582/584 series switch/annunciators and are repre-
sentative of those used in our original certification. They were chosen because of their
excellent sunlight readable characteristics and meet or exceed the requirements of Advi-
sory Circular 20-138. These are high quality devices and we encourage their use, Howev-
er, there are other comparable devices on the market that may be substituted at the install-
er/customers choice, such as the Mid-Continent Instrument, MD41.
These switch/annunciators are available through Honeywell Service Stock or direct from
our supplier, LCOMP Aerospace Controls. It is advantageous to order direct from LCOMP,
if possible, in order to avoid additional price mark-ups. LCOMP’s address and telephone
number are listed as follows:
