Failsafe Firmware Update
If your TriCoder firmware update is interrupted, you may end up with a TriCoder that will not function properly. If you have a 5000
version TriCoder, you can perform the failsafe update by either USB or serial port. If your firmware update fails, you must use the
following failsafe firmware update procedure:
1. Take the battery door and/or handle off of the back of the TriCoder.
2. Remove the NP-120 Li-ion Battery from The TriCoder
3. Locate the small switch in the right hand corner and slide the switch down.
4. Plug the battery back into place – noting that it can only be inserted one way and with the battery contacts facing the battery
connector.
5. Press the power On button on the TriCoder. The screen may not light up or come on at all since the firmware is presumably bad .
o Select the Firmware file for the TriCoder
o Follow the steps in the Software to update the Firmware.
o When the software completes the firmware update remove the Battery and return the Switch to the normal position.
o Re-Install the battery door and/or Handle and you will be ready to use the TriCoder again.
