¶ USB connection
With a JST-USB cable, you can connect to the display via the empty service port in the bikes wiring harness. You can then access it on a computer running SWTools (to adjust parameters, upgrade firmware, etc). When addressing the device, the credentials are guest:guest.
¶ Recovering the PIN
Once connected to the display, you can use term or emGUI to retrieve the PIN code from /permanents/pin/. This is useful if the PIN code has been forgotten.
¶ Teardown
This teardown of a Display v1 was done by Aubron on Discord:
- Display V1 has a siliXcon branded PCB (
ift2-ck1d) and appears to be a variant of SiliXcon VDS1 display (siliXcon is also the manufacturer of controller for Ösa/Kalk) - Pinout is not quite the same as the VDS1 pinout (shown below): no jumpers, and the cable that is completely disconnected (shown above) seems to be the USB terminals (pins 7-10 on the pinout).
Original siliXcon VDS1 pinout for comparison:
