This is one of my little hobby horses. Some VOCA companies quietly withdrew
the ability to plug more than 2 switches in a couple of years ago - yes you
can use a mouse mover, as Geoff noted, however this is not the same as
directional scanning with 3+ switches. With directional scanning when you
press right it goes directly to the next cell. With a switch operated mouse
(mouse mover) - you press right and the mouse starts moving to the next cell
- I think this is cognitively more demanding and also slower...
It is still possible to do directional scanning (e.g. using a
joybox/TheGrid) - but I don't think you'd be able to do it with the Dynavox
software (haven't tried on a V - now they've exposed the operating
system)...
Cheers.

Subject: 5 switch operated MT4
Not sure if anyone has done this already. Dynavox were not too helpfull
when asked and we are prety sure we could do the job using a Tash mouse
mover.
My colleague as been asked to provide multiple switch inputs (5) to a MT4
which only has usb and a serial port of some kind (not sure this is a
standard serial port).
Anyone done it and if so how and if not any ideas?
Thanks
