Night Vision Support Option
For NVIS capable units NVIS mode is enabled by a closure to ground through an
external toggle switch or maintained pushbutton switch. NVIS mode is annunciated
onscreen so an external annunciator is not required.
The input will always pull up to the de-activated state when disconnected .

Reversionary Attitude Option
The SN3500 supports a Reversionary Attitude Display when interfaced to a Attitude
Heading Reference System supplying Roll, Pitch, Heading , and lateral acceleration
data via Arinc 429. An optional key code is required to enable this feature. See the
Reversionary Control interface drawing in this manual for interface wiring
requirements. This option is not available when the SN4500 is interfaced to an analog
DME.
