Serial Port Interface

The following table lists pinouts for the Zebra Auto-Detecting DTE and DCE feature as it relates to the 9-Pin RS-232 Interface:

Pin	DTE	DCE	Description (DTE)
1	—	5V	Not used.
2	RXD	TXD	Receive data (RXD) input to the printer.
3	TXD	RXD	Transmit data (TXD) output from the printer.
4	DTR	DSR	Data terminal ready (DTR) output from the printer—controls when the host may send data.
5	GND	GND	Circuit ground.
6	DSR	DTR	Data set ready (DSR) input to the printer.
7	RTS	CTS	Request to send (RTS) output from the printer—always active when printer power is on.
8	CTS	RTS	Clear to send (CTS)—Not used by the printer.
9	5V	—	+5 V @ 0.75 A—FET Circuit current limited.

If you select

XON/XOFF

handshaking during printer driver setup, data flow will be controlled by ASCII control codes

DC1

(

XON

) and

DC3

(

XOFF

). The DTR control lead will have no effect.

The printer is configured as a Data Terminal Equipment (DTE) device. To connect the printer to other DTE devices such as the serial port of a personal computer, use an RS-232 null modem (crossover) cable and the pinouts shown below.

When connecting the printer through its RS-232 interface to any Data Communication Equipment (DCE) units such as a modem, use a standard RS-232 (straight-through) interface cable and the pinouts shown below.
