Single-Ended Channel Connections

Single-ended connections use only one signal wire per channel. The voltage on the
line references the common ground on the card. Signal sources without a local
ground are called "floating" sources. A single-ended channel can be easily connected
to a floating signal source. The standard wiring configuration is shown below.

supply. The ground references (AGND and
DGND) are connected on MIC-1816.
Counter 0/1 External Clock Input. The
