I don't think so, according to the following code taken from
ni_mio_common.c:ni_ai_cmd() (line 1343 if comedi version 0.7.64)
case TRIG_EXT:
{
...
reg |= AI_START_Select(1+(cmd->scan_begin_arg&0xf));
...
win_out(reg,AI_START_STOP_Select_Register);
}
and according to NI DAQ-STC Technical Reference Manual
(page 2-78 of 340934b.pdf) here is the layout of AI_START_Select :
0: Bitfield AI_START1_Pulse
1-10: PFI<0..9>
11-17: RTSI_TRIGGER<0..6>
18: The internal G_OUT
31: Logic low

No problem. For my tests I'm using NI connection box BNC-2120 to access
6025E signals.
