Steps 2 and 3

Step 2: Troubleshoot the interrupter

The interrupter is powered over USB and can be controlled using our 1T Panel software available for download at onetesla.com/downloads. You will need a mini USB cable to connect to the interrupter. It behaves like a MIDI device and can also be controlled via other MIDI software. See Appendix A for a description of 1T Panel.

The interrupter has two modes: Live mode (switch to the right) and Fixed mode (switch to the left). Note: every time you want to switch modes, you need to power cycle (unplug and plug back in) the interrupter.

Place the switch in the Live mode position (right-hand side). This places the interrupter into MIDI mode. Using a mini USB cable, connect the interrupter to a computer. Confirm that the USB device is recognized and does not throw an error. Use 1T Panel to raise and lower the power and confirm that the LED in the fiber optic transmitter raises and lowers in brightness accordingly.

If it doesn’t work

USB device is not recognized or drops out...
  • Confirm the ATtiny is installed in the correct orientation.
  • Check all parts carefully for correct values and orientations.
  • Check your soldering for bridges and/or cold joints.
  • Unplug all other USB devices.
  • If the interrupter drops out when you handle the USB cable, check your soldering of the USB connector.
  • Try a different computer to compare results.
  • (early kits) Replace your 3.3V Zener diodes with 3.6V Zener diodes. If using a USB 3.0 port, you can omit the Zeners altogether.

 
Interrupter doesn’t respond to software...
  • Ensure that the software you’re using is transmitting on MIDI channel 0.
  • Ensure that the software you’re using is outputting to the appropriate USB port.
