BH8-262 Firmware Update

The BarrettHand™ firmware resides on board the electronics located inside the hand. BH8-262 hand firmware is stored in RAM that receives its power from the Power Supply when the system is turned on and from an embedded super capacitor when powered down. This super capacitor is designed to maintain the firmware in RAM for two days. However, especially in humid weather, the memory will begin to degrade after two days and eventually will be cleared. Since degraded memory may result in erratic control, please reload firmware if the hand has been turned off for several days. When the firmware has been cleared or degraded, it will need to be reinstalled. The latest version of firmware should be uploaded to the hand whenever new software is installed on the host computer to ensure proper operation.

The download process takes only a few minutes, as follows:

  1. Verify the BarrettHand™ is plugged into the Power Supply.
  2. Verify the host computer is plugged into the Power Supply.
  3. Verify the Power Supply is attached to a power source.
  4. Run the BarrettHand Control GUI from Windows or Ubuntu.
  5. Select the Hand model number and either CAN or Serial depending on your connection.
  6. Open the appropriate file according to Table 1.
  7. Press the Upload firmware button in the Upload Firmware box.
  8. Follow the on-screen instructions:
    • BH8-262 users: Cycle power: Switch the Power Supply off, wait 5 seconds, and then turn it back on. The upload begins automatically.
    • BH8-280 users: Have the Hand powered for 5 seconds and then click OK to begin uploading firmware.
  9. After uploading the file, the BarrettHand™ is ready for operation.
  10. Initialize the software by pressing the Initialize Library button. Check that new firmware is version is reported correctly in the GUI.
