Manually setting the serial parameters
In addition to Learn Mode, the interface allows you to set the
serial parameters manually using DIL switches, which are
accessible after opening the interface housing. The meaning of
the DIL switches is described in the following tables:
Handshake
The Interface uses Hardware handshake and XON/XOFF hand-
shake. To suppress one of these methods, leave the corres-
ponding line unconnected. The built-in Overrun Buffer ensures
that no data are lose even when the computer sends up to 4kB
of data after the handshake stop.
