453-0032 WIRING TO 140-3349 TOGGLE SWITCH

The interface has two connections available on the D-sub connector to connect either aircraft

power 14 VDC or 28 VDC. The connections have internal current limiting resistors to protect the

built-in LED on the toggle switch, so it is critical to establish the proper connection between the

interface, the toggle switch, and the aircraft power.

The power supply inside the interface is designed to operate on 6.5 to 30 V input. Due to this

wide input range, a switching power supply is used to create 5 V for power distribution throughout

the system. This switching supply allows the system to draw on average approximately 125 µA

from a 14 V battery and 65 µA from a 28 V battery.

7.1 DIODES INSTALLATION

Ensure that the leads of the diodes do not touch the body of the toggle

switch, or any other contacts other than the ones mentioned below.

7.1.1 Solder the diodes 120-4007 to the toggle switch according to the following information:
