I/O Connector Signal Descriptions

Table 4-2. Signal Descriptions for I/O Connector Pins

Signal Name Reference Direction Description

ACH<0..3>GND — — Analog Input Channels 0 through 3 ground—These pins

are the bias current return point for differential

measurements. ACH<2..3>GND signals are no connects

on the NIPCI-6 111.

ACH<0..3>+ ACH<0..3>GND Input Analog Input Channels 0 through 3 (+)—These pins are

routed to the (+) terminal of the respective channel

amplifier. ACH<2..3>+ signals are no connects on the

NIPCI-6111.
