A floating differential hookup is handy when the signal source is floating with respect to ground, such as a battery,
The floating differential input will reject up to 10V of EMI energy on the signal wires.
WARNING!
Verify that the signal source is really floating. Check it with a voltmeter before risking the
3.4 DIFFERENTIAL
A differential signal is three wires from the signal source. The signals are Signal High (CH# HI), Signal Low (CH# LO) and Signal Ground (LLGND).
A differential connection allows you to connect the
