Using a Switch Interface with the Speaking/Companion Software

The Series 4 Speaking/Companion software can have one or two switch inputs.
Switch 1 is the zero key from the number key pad. Switch 2 is the delete key from the number key pad. You cannot use the standard zero from the main keyboard or the backspace key. You will therefore need to use a switch interface which can be setup to send these keys when a switch is pressed.
The only switch interface that we have tested successfully with the Speaking Software is the Crick USB Switch Interface. The Switch Click USB and Mini-Click from TASH both definitely will not work. A switch adapted mouse will not work.
