Using the 13-Sensor Flex Cables¶
Follow this procedure to connect and test the flex sensor cables:
- Be sure to update the JSON configuration file as described in the First Use section before proceeding.
- The flex cable connectors are located on the core module on the top and bottom of the board, nearest the USB connector:
- Before inserting the flex cables, verify that the black locking latch on both flex connectors is in the UP/UNLOCKED position as shown in the image above.
- Remove the flex cables from the panel. EXERCISE CARE IN REMOVING THE CABLES AS THEY CAN BE EASILY DAMAGED.
- The cables are difficult to manage after they are removed so you may want to tape them to a piece of cardboard or something similar for testing as shown below. NOTE: The center sensor in each cable assembly is non-functional.
- The flex cables must be inserted into the flex connectors with the cable contacts facing away from the core module:
- Be sure to insert both cables completely into their connectors and press the locking latches toward the core module to close (only the top cable is shown inserted).
- Your completed assembly might look like this:
- Position a Valve basestation within line-of-sight of the flex cable sensors. The preferred location is 5 to 10 feet away and approximately 5 feet above the sensors. You can use a Gen2 basestation or a Gen1 basestation (if using a Gen1 basestation, verify it is in mode A).
- Connect the core module to the computer with the USB cable, wait for the USB connection tone, and launch
lighthouse_console.exeas described in the First Use section.
- At the
lh>prompt, type the command
sensorcheckand press ENTER as shown below. NOTE: If lighthouse_console does not recognize the
sensorcheckcommand, update your SteamVR™ HDK software to the latest version.
- The sensorcheck command will display basestation “hits” on each sensor as shown below. To stop the test, type the
sensorcheckcommand again and press ENTER.
- In the sensorcheck output, you will note that SensorID 12, SensorID 13 and SensorID 26 do not have data. SensorID 26 will not have data because it is not a valid sensor location since the Shoto HDK only has 26 sensors total (0 through 25). SensorID 12 and SensorID 13 do not show data because they are the non-functional sensor locations on each flex cable.
