Installing Multicom

MultiCOM is a USB to RS232 converter developed for controlling via the RS232 serial interface. It is connected to the PC via the USB port and has 6 serial 9-pin ports. It also has a free USB port for the connection of the USB hardware key.

  1. First install Clarity. Multicom driver is by default installed in Typical installation of Clarity. It can be found in Utils section of Choose Components step.
  2. Connect Multicom to a USB port in your computer. It will be detected automatically. LED diodes will be turned on one by one.
  3. Connect your devices to the Multicom RS232 ports.
  4. Start Clarity and then add each device to a specific Clarity instrument as explained in Adding a new device.
  5. Select the appropriate port from the list during the device setup.

    Note:

    When using functions like Autodetect and Check LED diode of selected port will blink. This can be used to find the desired port number on Multicom.

  1. Check the LEDs on the top panel to find out about the status of Multicom and whether it has been installed properly.

    Green LED status:

    • OFF – not connected to USB, the driver is not installed or Multicom is in suspend mode.
    • ON (Constant) – idle state, no communication.
    • BLINKING:
      • Two short consecutive blinks – only sending data from USB to the COM port.
      • Turned off twice consecutively – only receiving data from the COM port into USB.
      • Constant blinking – both sides are receiving and sending data.
