How the A/D Expander Works
The A/D Expander measures two channels of analog input, ranging from 0-4V. The input can exceed 4V (up to 6V maximum), but values over 4V will read as
maximum. The maximum resolution is 15 bit.
Connecting the A/D Expander to the Recorder
The 4 wire connector attached to the A/D Expander plugs into either the G-Force or EGT (“Thermo”) port of your Data Recorder as shown in Figure 1. Make sure that
you connect it in the correct location on the recorder, and with the correct polarity! NOTE: If you are already using both EGT and G-Force expanders, email us at
support@eagletreesystems.com
for more info.
Calibrating the A/D Expander
We offer fee based customization to our Windows software for calibrating the data from the
Expander, for your specific application. Email support@eagletreesystems.com

Pinouts of the A/D Expander
There are two 3 pin input leads (with Futaba style female connectors) attached to the expander.
With each of these, the connections are as follows:
Red - 4V regulated output (maximum around 50 mA, overload protected)
Black – Ground
White – Analog In, 0-4V (don’t exceed 6V)
