Table 6 - S100 Analog Input Interface
The S100 has 3 analog inputs that can be used with some firmware versions to measure analog
voltage levels and trigger events at specific values. For example, the S100 can be configured to read
values from a strain-gauge sensor connected to one of the analog inputs and send a message when
the weight decreases a certain amount (i.e., if the aircraft releases a load).
The analog inputs can measure DC voltage levels from ~0V to +28V.
You may be required to change the firmware version on your S100 in order to use the analog inputs;
call Latitude Technologies at
+1 (250) 475-0203
and ask for technical support.
