The specification of the bridge cable we provide:

  • For the UHK 60: 11cm collapsed – 30cm expanded, or 0.35 – 1 foot, cross-over wiring
  • For the UHK 80: 13cm collapsed - 45cm expanded, or 0.45 - 1.5 feet, straight-through wiring

The bridge cable is not necessary for the UHK 80 because it's a fully wireless keyboard; however, it's useful if you want to permanently power the halves from a single USB cable.

Even though we don't offer an alternative bridge cable, you should be able to make, get made, or purchase one easily and cheaply. The following criteria apply:

  1. The cable must utilize 4P4C jacks on its end.
  2. The cable must feature 4 wires to connect each of the 4 pins of the jacks.
  3. The cable should be as short as possible for the UHK 60. The longer the cable, the higher the chance it'll cause your UHK 60 to malfunction. If you need a long cable, use a straight cable instead of a spiral cable to minimize overall length. Then, you can go as long as about 3 meters.
  4. Depending on your UHK model, the jacks' wiring must be cross-over for the UHK 60 or straight-through for the UHK 80.
