Keyboard Interface
Adept MV Controller User’s Guide, Rev C 107
8.5 Keyboard Interface
The VGB module supports an AT-style extended keyboard with an integrated trackball.
The keyboard interface is a bidirectional, synchronous, serial interface. The keyboard
communicates with the UART on the VGB via the clock and data lines. The keyboard
input uses a standard 5-pin DIN connector. The Keyboard connector pin assignments are
shown in Table 8-3.
8.6 Pointer Interface
The VGB module supports a standard Microsoft serial-mouse protocol compatible
pointer. The pointer input uses a standard 9-pin D-sub connector. The pointer interface is
serial, not parallel. Pin assignments for the Pointer connector are shown in Table 8-4. See
section 8.2 for configuration and compatibility.
