The multitasking computers of the BASIC-Tiger™ family already possess a
number of I/O lines inside the module. If that is not enough, the I/O
structure can be expanded almost without limit. For this a series of
I/O expansion modules with digital and analog channels are available.
I/O expansion modules are connected through an 8-bit bus and get an
individual address. In that way up to 4,096 channels can be integrated
into one system. On software side the access of external I/O channels
is as simple as when addressing internal I/O channels. For this the
xPort system as well as adjusted device drivers are available.
The xPort expansion structure also is fully compatible to the I/O
expansions of board level products, which are single board computers of
the SBC series and EuroCard computern (TEC series).
