send trigger to trigger station

Dear Inquisiters,
I am programming an experiment in which at the end of each trial I'd need to send a trigger to a trigger station which then activates a Digitimer electrical stimulator. 
The thing is that the trigger should be sent either to a BNC1 OR to a BNC2 cable, depending to the specific condition (pain VS. safe) to which the trial is associated.  Indeed, these two cables are connected to two different stimulators (BNC1 is connected to a stimulator that will deliver a painful stimulation and BNC2 to a second stimulator that will deliver a soft stimulation, so if the trial belongs to a safe condition, the trigger at the end of the trial should be sent to BNC2, while if the trial is a "pain" trial the trigger should be sent to the BNC1 cable). 
Is that possible? And if so, how should this be implemented correctly?
Thank you very much to all of you.

Inquisit can trigger external equipment via the parallel port, the serial port, or it can make use of a Cedrus StimTracker.

If your trigger station has serial or parallel port input connectors and can route to the desired BNC output based on the TTL signal received, then you can make things work. If your trigger station does not support serial or parallel port input, then no.

Thank you so much Dave, I'll have a try then!
