Table 63 DME Serial/Parallel Output
* Used for 2x5 parallel DME tuning.
NAV DME Common must be pulled low for the AeroNav XXX to channel the DME. DME is
active if the voltage to ground is <1.9 V or the resistance to ground is <375 Ω.
Outputs is not more than 1.0V while sinking 20 mA.

NAV Serial DME – DATA P1006 19 Output
NAV Serial DME – Clock P1006 18 Output*
Serial DME – CHAN REQ/PAR DME – 4MHz P1006 20 Output*
Serial DME – RNAV Mode/PAR DME – 2MHz P1006 21 Output
NAV DME Common P1006 22 Output
Table 64 DME Serial Tuning
Output high is >8V when driving a 360Ω and < 10mV for a low.
NAV DME Common must be pulled low for the AeroNav XXX to channel the DME. DME is active if the
voltage to ground is <1.9 V or the resistance to ground is <375 Ω.
6.2 Bezel Lighting
The AeroNav XXX can be connected to any of the following avionics lighting sources: 5/14/28VDC or 5
VAC. Dimming controls are described in Section 7.5.6.
