SilverFox HomeOne and B8J controllers


 B9 on BMW R1200GS 2010

Mechanical installation:

Slide the plastic adjustment ring on to the 22 mm handlebar. By rotating the adjustment ring you can move the controller forwards or backwards on the handle bar. Clamp the device on the adjustment ring evenly with two M4 screws.


You need to move your mirror-clutch assembly just few millimeters to get the needed space (9 mm) for SilverFox clamp arm.​​

Connect the power cord to the fuse protected 12VDC output of your bike (Operating voltage range 5-24VDC). Double check to make sure to connect the cords are correct; Brown wire to negative (-) and White wire to positive (+).  

HomeOne has both Bluetooth and wired data connectionConnect Yellow wire to your unit TX wire and Green to RX wire. At the moment DMD T865 tablets support the wired connection. Make sure the wires are connected right before power up the unit. TX/RX don't like 12V at all!

New H1 (from 5/2024) units are supplied with M12 connectors to plug&play with T865 harness. And with extra cable strip for just 12VDC power feed for other systems.
