CONNECT is a software utility that enables users to interface directly with any NexSens X2-Series data logger using a UW6-USB-485P cable. It supports a growing number of diagnostic and configuration tools to facilitate system setup and troubleshooting.

Software Installation

  1. Download the latest version of the CONNECT utility from the Support | Downloads section of the NexSens website.
  2. Launch the downloaded application to begin installation. If prompted by Windows, give permission to install the app by clicking More info and then Run anyway.

Figure 1: Select More info.


Figure 2: Select Run anyway.

  1. Select Next to start the installation wizard, then specify the installation folder for the program as well as user accessibility. Using the default selections is recommended.

Establish Connection

  1. Ensure the PC is connected to the internet, then connect a UW6-USB-485P cable to an available USB port and wait for notification that the device has been installed. To confirm success, open Windows Device Manager to confirm the COM port. Consult a network administrator if it does not install automatically.
  2. Launch the CONNECT program.
  3. From the Properties window, select the proper COM Port for the cable from the Comm Settings tab on the far right.
    1. Baud must be 57600 for communication with the X2.
    2. If using an X2 base radio, visit the Configure X2-Base Radio article.

  1. Connect the UW plug end of the USB cable into the center 6-pin port of the X2 data logger or the SOLAR/COM port of an X2-CB buoy.
    1. Do NOT connect sensors to the X2 before enabling all proper scripts and supplying 12V power to the logger. A brand new logger not previously configured by NexSens will immediately begin a sensor detection when 5V power from the USB is applied. Depending on the sensor, 5V from the USB may or may not be sufficient for the sensor to power on and become available for detection, thus certain sensors will be detected and others will not.
    2. For more information on X2 sensor detection, refer to the following articles:


  1. Click the Read RTC button on the CONFIG tab. A response in the X2 Time field indicates a successful connection with the logger.
    1. Note if the connection fails, wait 30 seconds, then try a second time. Startup processes can interfere with external communications.
