RS-232 And RS-422 Serial Interfaces

Note

The RS-232 and RS-422 serial interface circuit characteristics are

 

compatible with the Electronic Industry Association Specifications

 

EIA® -232-E and EIA-422-B.

 

 

The RS-232 and RS-422 serial interfaces enable the printer to operate with bit serial devices that are compatible with an RS-232 controller. The input serial data transfer rate (in baud) is selectable from the printer operator panel. Baud rates of 600, 1200, 2400, 4800, 9600, 19,200, and 38,400 are available for RS-232 and RS-422.

The input format consists of a single start bit, 7 or 8 data bits, and one or two stop bits. The number of data bits is determined by printer configuration. The data bits are interpreted with the least significant bit first. Parity checking is determined by printer configuration options selected from the operator panel.
