Zebra Auto-Detecting DTE and DCE for 9-Pin RS-232 Interface
Important • 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, data flow is controlled by
the ASCII control codes DC1 (XON) and DC3 (XOFF). The DTR control lead will have no
effect.
Connecting the Printer to a DTE Device
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.
