Hi,
you can try several things. On windows you may use the io libraries: io32 mex-files
or ParPulse.
On linux try this ppdev mex interface.
You may also tweek matlabs data acquisition toolbox to sub-milisecond EEG triggering. For more information on this have a look at this site: TTL-Triggering Windows
Best, Norman

I am also using an actichamp. Note that your control computer would need to have a parallel port. USB-to-parallel port adapters do not seem to work. I'm trying to do this with a linux laptop with only USB ports. Based on the following webpage, I'm going with NEUROSPEC's MMB Trigger Box.
