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.

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
for more info.
