Interfacing To A Host Computer

Every MLP 3040 is equipped with an RS-232C Serial Interface. Optional factory installed interfaces are also available for IrDA (Infrared), Bluetooth®, and Wi-Fi®. When the printer is equipped with one of the optional interfaces, the interface that is selected in the Interface Menu as described on page 21 is the one that will be active and the other interface will be ignored.

Note: To print out configuration information for the currently selected interface, you may press and hold the RS-232C Serial Interface Enter Button until “Printing Setup” is displayed.

Note: To switch back-and-forth between the RS-232C Serial interface and an optional interface (if installed), you may continue to the Pin # Enter Button until “Interface Now ‘interface’” is displayed. After the Description Enter Button is released, the alternate ‘interface’ will be selected and the setup information for the newly selected interface will be printed. (This is merely a shortcut method and accomplishes the same result as using the Interface Configuration Menu. This feature was added in printer firmware version 2.1.)

RS-232C Serial Interface

To communicate using the Serial interface, “Serial” must be selected in the Interface Menu as described on page 21. If there is no optional interface installed, Serial will be the only interface available. When using the Serial interface, the baud rate, data bits, parity, stop bit(s), and handshaking method (XON/XOFF, ETX/ACK, RTS/CTS) must be set to match the settings on the host computer. If these settings do not match, errors and/or lost data may occur. The serial connector is an “RJ” type connector located on the side of the printer. The pin assignments are shown below.
