The command is:

7 triggers

This returns the configuration report:

Triggering on Data from:

Tap#2 20s/s 70 = Chans 4 5 6

Tap#2 20 s/s BandPass: 2.0->9.0Hz


(Note: Channels 4, 5 and 6 correspond to the bandpassed versions of data on Channels
0, 1 and 2)

The trigger operating mode can be disabled simply by sending the command:

0 triggers


DEFINING CHANNELS FOR OUTPUT ON TRIGGER

When a trigger is declared, the channels to be output are defined using the
TRIGGERED command. This takes 2 arguments, the tap number (0-3) and the
components (an integer defined from the bit values as for TRIGGERS defined above).
For example:

0 7 triggered

will cause all three components to be output at 200 s/s on triggering. The configuration
report will be:

Output Triggered Data from:

Tap#0 200s/s 07 = Chans 0 1 2
