ZD611R RFID Link-OS™ Desktop Printer

Serial Port Interface

This section explains the connector wiring Zebra Auto-Detecting DTE and DCE for 9-Pin RS-232 Interface.

9-Pin RS-232 Interface
Pin	DTE	DCE	Description (DTE)
1	—	5V	Not used
2	RDX	TXD	RXD (receive data) input to the printer
3	TXD	RXD	TXD (transmit data) output from the printer
4	DTR	DSR	DTR (data terminal ready) output from the printer -- controls when the host may send data
5	GND	GND	Circuit ground
6	DSR	DTR	DSR (data set ready) input to the printer
7	RTS	CTS	RTS (request to send) the output from the printer -- always in the ACTIVE condition when the printer is turned on
8	CTS	RTS	CTS (clear to send) - Not used by the printer
	5V	—	+5 V @ 0.75 A - FET Circuit current limited

The maximum current available through the serial port, USB port, or both will not exceed a total of 0.75 Amps.

When XON/XOFF handshaking is selected in the printer driver, the data flow is controlled by the ASCII control codes DC1 (XON) and DC3 (XOFF). The DTR control lead will have no effect.

Interconnecting to DTE Devices – The printer is configured as data terminal equipment (DTE). 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.

Interconnecting to DCE Devices – When the printer is connected via its RS-232 interface to data communication equipment (DCE) such as a modem, a STANDARD RS-232 (straight-through) interface cable must be used.
