ZD411D Printer Setup
Serial Interface
The printer supports Serial Portas a factory configuration or as a field upgrade kit.
IMPORTANT: Do not use RS-232 cable adapter dongles for data terminal equipment (DTE) and
data communication equipment (DCE) with this printer. Some dongles can interfere with the
operation of USB Host port devices at printer power-up.
The printer uses a Null Modem (cross-over) cable forDTEcommunications. The required cable must have a
nine-pin D-type (DB-9P) male connector on one end which plugs into the mating (DB-9S) serial port located
on the back of the printer. The other end of this signal interface cable connects to a serial port on the host
computer. For pin-out information, refer to Interface Connector Wiring Diagram.
The serial port communication settings between the printer and host (typically a PC) must match for reliable
communication. The Bits per second (or Baud rate) and Flow control are the most common settings that get
changed.
Serial communications between the printer and the host computer can be set by:
ZPL programming ^SC command.
Resetting the printer to its default printer configuration.
Factory defaults for serial communication settings are 9600 baud, 8-bit word length, NO parity, 1 stop bit,
and XON/XOFF (Software data flow control in the Windows-based host system).
