RS-422 Serial Interface

RS-422 Serial Interface

This interface is used with bit serial devices compatible with EIA- RS-422B or CCITT V.27 and V.11 standards. The interface circuit characteristics are compatible with the Electronic Industry Association Specification.

The printer is configured as Data Terminal Equipment (DTE).

The serial data transfer baud rate is selectable from the control panel. The input format consists of a single start bit, 7 or 8 data bits, and one or two stop bits. The operator can set the number of data bits from the control panel. The data bits are interpreted with the least significant bit first. The operator can also set parity checking via the control panel. The printer interface uses a first-in/first-out buffer with the size selectable from the control panel.

The asynchronous interface accepts data as it is provided by the host computer.

The maximum cable length from the host computer to the printer is 4000 feet.

The maximum baud rate supported by the RS-422 serial interface is 256 KB.
