CONFIGURING THE HOST COMPUTER PORT
Next set the positions on Dipswitch 2 to correspond with the communication
parameters set for the host computer. The adapter always communicates with
the host computer using seven data bits, one start bit, and one stop bit. The baud
rate settings for Positions 5–8 of Dipswitch 2 are shown in Table 3–2.
Position 1 of Dipswitch 2 enables or disables parity bit generation and
checking.
Position 2 of Dipswitch 2 selects even or odd parity when parity
generation and checking is enabled.
Position 3 of Dipswitch 2 selects full duplex or half duplex operation.
Position 4 of Dipswitch 2 selects synchronous or asynchronous modem
communications. Selecting synchronous only enables the adapter to use
the TxCLK (DD) and RxCLK (DB) RS–232–C control signals. The
adapter will not process synchronous control characters from
synchronous data link protocols such as BiSync.
