Serial Interface

Serial Interface

RS-232C is the standard serial interface for data terminal equipment

 

(DTE). The cable connector at the printer should be a D-subminiature

 

Cannon or Cinch DB-25P pronged connector or equivalent

 

conforming to EIA standards.

 

The following table shows pin assignments commonly used by most

 

processors.

Note the following:

•“Input” indicates a signal sent to the printer from the processor.

•“Output” indicates a signal sent from the printer.

•The signal level for mark (logical 1) is –3 V or lower; for space (logical 0), it is +3 V or higher.
