Communication Specifications
Both serial and parallel data communication interfaces are available for the
S-Series printers. The S-Series printer sends and receives standard ASCII
(American Standard Code for Information Interchange) data characters.
With ZPL II
®
, the Error Detection Protocol feature provides virtually error-free
communications. Refer to the user’s guide for further information.
Serial Data Communications Overview
The S-Series printers have a Data Terminal Equipment (DTE) port that supports
RS-232 serial data communications. The RS-232 interface has a standard 25-pin
DB25-S connector located at the rear of the printer. For all RS-232 input and
output signals, the S-Series printer follows the EIA RS-232 and CCITT V.24
specifications for signal levels.
The baud rate, number of data bits, and parity are user-selectable via DIP
switches at the rear of the printer. Parity only applies to data transmitted by the
printer. The parity associated with received data is ignored. Further information
on the settings of these switches is contained in the printer’s user’s guide.
Serial Data Signal Levels
Serial data signals are defined as either MARK or SPACE, while control signals
are either ON or OFF. The output levels for the S-Series printers are as follows:
MARK or OFF = - 7 to - 10 Volts
SPACE or ON = +7 to +10 Volts
Serial Interface Connector Pinout and Description
A DB25-S connector is located at the rear of the Zebra S-Series printer and
provides serial data communications to a host using RS-232 signaling.
The pinouts and signal descriptions for the DTE port are as follows:
