5.7.13 Hardware
The Hardware setup has a sub menu for Digital inputs, Indicator, Communications, Battery,
Remote Stick, Flaps, Bridge and Compass module.
5.7.13.1 Digital Inputs
Digital inputs are not enabled on S8/S80 Club version. To purchase this option
please refer to Chapter 3.2.3.
5.7.13.1.1 VP Input (Vario Priority)
When this input is activated by grounding the appropriate wire, the unit will change over to
Vario immediately. This input wire is set open (not grounded) as a factory default on
delivery. This switch has priority over all SC switching methods. This means it will override
all other signals for SC and switch unit to vario mode. This input is not wired in standard
wiring – it must be wired by the customer.
5.7.13.1.2 SC Switch
The LXNAV S8x/S10x has an input for an external speed command switch. Using the
external switch, it is possible to manually switch between SC and Vario. Setting the SC
switch to ON mean that closing the switch will cause the instrument to enter SC mode.
Setting the SC switch to OFF means that closing the switch will select Vario mode. There is
a third option by setting SC INPUT to TASTER and connecting a push button to the input;
each key press will toggle between SC and Vario (mandatory setting for LX Remote, which
provides a push button for SC).
