RS422 > Centronics Interface, 1+1 KByte, Model 62009
The number of stop bits may be any. Only the format
7 data
bits, no parity, 1 stop bit
is not supported by Learn Mode of the
interface.
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 1kB
of data after the handshake stop.
The meaning of the DIL switches can be taken from the table
