External Trigger Wiring for a Group Instrument

2-19.

External Trigger Wiring for a group instrument refers to the triggering configuration in which you connect the Master TO (Trigger Out) line to each Slave TI (Trigger In) line and provide a common connection to the GND line for each instrument. This configuration provides improved synchronization of the group instrument when the scanning intervals are 1 second or less.

Figure 2-7 shows a typical wiring connection for a group instrument. Use NetDAQ Logger to configure a group instrument as described in Chapter 3 of this manual.

Controls and Indicators

2-20.

The front panel provides a display and a set of control keys; the rear panel provides the power switch and Ethernet status indicators. See Figures 1-2 through 1-4 for an overall view of front and rear panels, and "Front Panel Operating Procedures" later in this chapter for procedures that use the front and rear panel controls and indicators.
