J1-21

HEADING VALID

This pin is configurable on the Maintenance page for either valid high or valid low. An open 
HEADING VALID pin always indicates invalid.

J1-77

HEADING X

J1-58

HEADING Y

J1-59

HEADING Z

Three-wire XYZ format with Z grounded. Input impedance is no less than 10 kilohms. Maximum 
lead-to-lead voltage is 11.8 Vrms.

NOTE: To accept this input HEADINGVALID (J1-21) must be valid. The 26 VAC used to excite the 

heading source synchro must be of the same phase as the KSN 7xx 26 VAC reference 
input.

J1-6

HDG REF HI

This is the indicator 26 VAC reference. Input impedance no less than 10 kilohms.

J1-7

HDG REF LO

This pin serves as the 26 VAC return. Impedance to AC GND less than 0.1 ohm.

Refer to Figure 3-7 for the heading interface - XYZ interconnect diagram.

Refer to Figure 3-8 for the AHRS interface interconnect diagram.

HI:

No less than 18.5 VDC (or two-thirds the voltage applied to the 
18-33 VDC AC POWER).

Load Resistance:

No more than 3.5 VDC. Input impedance no less than 10 kilohms.
