12.4 Signal terminated when using Trigger In
If you use the Trigger In to start the STG and the stimulation protocol is terminated right after
start, check the Trigger Settings. If the Use Trigger as Gate function is selected, a protocol will
only be active as long as the Trigger is HIGH. If the Single Trigger function is selected, the STG
is armed and waits for an external trigger to execute the stimulus protocol one time only.
Switch to Stop, Restart or Ignore.
12.5 Signal is not Repeated / Pulse Train Fails
The STG fails to generate a train of pulses. When a pulse is programmed in MC_Stimulus II and
then repeated (in the Trigger Settings dialog box) (with the Repeat option), the STG abruptly
stops after it has generated the waveform only once. (If another STG is connected to the computer
to run the same protocol, the stimulator has no problems on repeating the pulse.)
Possible causes:
? If you change the stimulus protocol after the download, even if only the number of repeats
were changed, you need to download the modified stimulus protocol to the STG. Otherwise,
the changes will not be applied. (If another STG is connected to the computer, you will have
to download the stimulus protocol, including the changes, to be able to stimulate at all.)

Select Download or Download and Start on the STG menu (or on the toolbar) after you made
any changes to the stimulus protocol in the MC_Stimulus program.
