Table 3-7 KLN 90B Signal Inputs
OPEN = GPS displayed (when an indicator resolver is
connected to the OBS resolver inputs)
GND = GPS not displayed (when an indicator resolver is
not connected)
OPEN = Normal Operation
GND = Take Home Mode
OPEN = Primary Long-range Navigation System
GND = Secondary Long-range Navigation System

This pin is used as a mode programming pin on power-up
and later as a select input.
This pin is used as a mode programming pin on power-up
and later as a control input.
The Data Loader RS 232 input is designed to communi-
cate with the dataloader
The RS 232 input is designed to communicate with devic-
es, i.e. air data and fuel flow sensors via RS 232 format
(refer to Appendix
ENABLED = Open (or tied to A/C Power thru a passive
load)
DISABLED = GND (This pin also functions as an output,
refer to section 2.3.6.2.X.

Gray Code Altitude Signals (0 V. to 28 V.) These inputs are diode
isolated inside the KLN 90B on all units above S/N 1542
OBS resolver sine, nominal input impedance = 36.5 K ohms (ac)
and 100 K ohms (dc)
