2.3 SINGLE-ENDED

A single-ended input is two wires connected to the board, a channel high (CH# HIGH)

and a Low Level Ground (LLGND). The LLGND signal must be the same ground the

PC is on. The CH# HIGH is the voltage signal source (Figure 2-4).

2.4 FLOATING DIFFERENTIAL

A floating differential input is two wires from the signal source and a 10K ground

reference resistor installed at the input. The two signals from the signal source are

Signal High (CH# HIGH) and Signal Low (CH# LOW).

The reference resistor is connected between CH# LOW and LLGND pins.
