Hi Larry,
The valve we supply with the port interface board is Lee Company part# LHDA1231115H. Specs are available here. It can gate air up to 15 PSI (I'd use much less to be safe!), and it should fully open and close in 2ms when gating air.
The port interface has the following connections:
-RJ45 (Ethernet) jack: Connection to Bpod state machine
-Valve (2-position screw terminal): + and - connections to valve driver circuit in Bpod state machine
-Infrared emitter, phototransistor and visible LED (6-position screw terminal) with connections as marked on circuit board. 'S' is a 5V tolerant digital input channel, which is pulled weakly high and typically connected to the phototransistor of a port or lickometer.
Please let me know if this was the information you were looking for.
-Josh
