Connect the MIC to a Receiver

  1. Using a customer supplied wiring harness, connect the MIC serial port to a serial port on the OEM7 receiver. The MIC serial port is available on the communications connector (P301) of the MIC.

    See MIC Connectors for the pinouts of the communications connector. See Connecting Data Communications Equipment for information about connecting a serial port to the receiver.

    All signal I/O on the MIC, with the exception of the USB port, are at LVCMOS levels.

    To connect the MIC to devices that use other signals levels, such as a computer with an RS-232 serial port, an interface circuit that converts LVCMOS to the other signal level must be used.

    COM Port Recommendations

    OEM719

    OEM7600

    OEM7700

    OEM7720

    All of the COM ports on these receivers use LVCMOS levels and are signal level compatible with the MIC serial port.

    OEM729

    Use COM2 or COM3 of the OEM729 receiver to connect the MIC serial port. These COM ports use LVCMOS levels and are signal level compatible with the MIC serial port.

    COM1 on the OEM729 receiver can use RS-232 levels (default) or RS-422 levels and is not signal level compatible with the MIC serial port.

    For information about the OEM7 receiver card connectors and pinouts, refer to OEM719 Technical Specifications, OEM729 Technical Specifications, OEM7600 Technical Specifications, OEM7700 Technical Specifications or OEM7720 Technical Specifications.

  2. Connect a computer (for monitoring and configuration) to the OEM7 receiver.
    Refer to Connecting Data Communications Equipment for information about connecting data communications equipment to an OEM7 receiver.
