2To assign functions to the incoming trigger signals, move the cursor to one
of four trigger signal parameters 1–4 in the INPUT section.
3 Rotate the Parameter wheel to select the desired function from the list below
the INPUT section, then press [ENTER] to confirm the selection.
4 Select one of two buttons located to the right of trigger signal parameters
1–4 to specify how the incoming trigger signals will be detected.
• .......... When the switch is grounded (Low), the trigger signal is active and the
selected parameter changes.
• .......... When the GPI Input goes High (open), the trigger signal is active and the
selected parameter changes.
At this point, when the DM1000 receives the trigger signal at the CONTROL port, the
selected parameter changes.
5To select parameters or controls as the trigger signal sources, move the cur-
sor to the OUTPUT section and select the desired trigger signal parameters
1–8 in the same way as for the INPUT section.
6 Use the buttons located to the right of the trigger signal (1–8) parameters
to switch the polarity of the trigger signals that are output when you control
the trigger sources.
• .......... The GPI Output goes High (open) when the trigger signal source is active.
• .......... The GPI Output goes Low (ground) when the trigger signal source is active.
