The TSD116 series is used for externally triggering data acquisition, remote event marking, or psychophysiological response tests. The switches connect to the UIM100C digital I/O ports and can be monitored as input channels. The TSD116 series incorporate momentary ON operation (switch is ON only when pressed).
TSD116A is a single channel hand switch
TSD116B is a single channel foot switch
TSD116C is a compact eight channel digital marker box. The TSD116C allows the user to independently mark events, or provide responses, on up to eight channels simultaneously. Because digital channels can be interleaved with analog channels, when using AcqKnowledge, it's easy to assign separate digital channels as event markers for individual analog input channels.
