Connect Your Camera to a Bulkhead

Preparing the JST Cable Connection

1

Review the wire functions before connecting

Ensure you do not mix up the +5V Power and Ground. Doing so can permanently damage your device and void warranty.
2

Ensure the following two wires are twisted/intertwined. Twisted pairs ensures the data signal is strong.

3

Connect the wires to the JST Connector

4

Connect the JST to the Adapter

5

Connect the Adapter to the USB Port on your computer

Test Your Camera Online

Connect the USB cable to a computer to confirm the camera is working and in the correct orientation. You can test the camera using our tool below.

Troubleshooting

Ensure that the wire colors match their respective functions when connected to the JST connector. Even a single crossed wire will prevent the camera from being recognized.
Twist the White (D-) and Yellow/Green (D+) wires together along their length, as shown in Preparing the JST Cable Connection. The camera uses a USB 2.0 High-Speed connection, which needs a twisted data pair to reject interference. Without it, the signal may be too weak for your computer to recognize the camera.
Make sure the wires are seated securely in the JST connector.Make sure the JST is pushed all the way into the USB adapter, and the adapter is securely plugged into your USB port.The camera can draw 200–320mA at 5V, depending on the model. Try plugging the adapter directly into your computer, rather than a low-power USB hub, to ensure it is getting sufficient current.
Check if your computer’s operating system is detecting the camera at a hardware level, even if it’s not showing an image yet. Since it connects via USB, we are looking for a USB device connection.
  1. Right-click the Start button (or press Win + X) and select Device Manager.
  2. Expand the following categories to look for the camera, exploreHD:
    • Cameras
    • Imaging devices
    • Sound, video and game controllers
  3. If the wiring is slightly off or the data lines aren’t twisted properly, Windows might detect something but not know what it is. Expand Universal Serial Bus controllers and look for anything labeled Unknown USB Device (Device Descriptor Request Failed).
Keep the Device Manager open and unplug/replug the USB adapter. The list will refresh; watch to see if any new devices appear or disappear.
If the camera disconnects shortly after being plugged in, check the Linux kernel log (sudo dmesg -w) for errors like these:
This error can have more than one cause. Check each one below.

Bad Firmware

Corrupt or outdated firmware can stop the camera from initializing. Update the camera firmware with the DWE Firmware Loader:

exploreHD Firmware Update

Update the firmware on exploreHD series cameras.

Bad Cable

A damaged or incorrectly wired cable can corrupt the USB signal. Make sure that the wiring is correct and that the data wires are twisted:
