Chapter 3 Signal Connections

TRIG<3..0> Triggers<3..0> are TTL I/O lines used to start or stop an acquisition or output

an acquisition status. You can program the triggers to be rising- or falling-edge

sensitive. You also can program the triggers to be programmatically asserted

or unasserted, which is similar in function to a digital I/O line, or to contain

specific pulse widths or internal status signals by using the onboard events.

CTRL<3..0>± Use the control lines on the NI 1410 to control camera features and timing

information, such as generating integration or shutter pulses. You can generate

either static or dynamic signals and either TTL or differential signals on these

lines.

DGND DGND is a direct connection to digital GND on the NI 1410.

CHASSIS_GND CHASSIS_GND is a direct connection to the computer’s chassis, which is

grounded through the power cord.
