Hi,
I'd like to trigger a transcranial magnetic stimulation (TMS) device using an Inquisit TTL signal. I've successfully used a variant of the below code to send signals to an EEG amplifier (TMSi Polybench). Unfortunately, I haven't had any luck so far with the TMS trigger. The TMS device requires the following inputs:

TMS MagPro Trigger Input
DSUB 9 pin Female
Pin 1: Trigger Input
Pin 2: Trigger Output
Pin 3: Ground. (Reference)
Pulse width > 5µs
TTL + CMOS levels accepted
Input Impedance > 10 kΩ
Default: Falling edge/Rising edge (user defined)

My Inquisit script attempt (relevant sections only):
<port triggersignal>
/ port = LPT1
/ subport = data
/ items = ("11111111")
/ erase = ("00000000")
</port>

<trial test>
/ stimulustimes = [0=start; 1000 = trigger, triggersignal]
/ validresponse = (noresponse)
/ trialduration = 5000
/ recorddata = false
</trial>

Any help would be very much appreciated!
