I got 10 PCB's left over, if anyone is interested in a bare PCB send me a PM.

The SBL wire is pulled up to 5V with a 270 ohm resistor, through a diode. This is the recessive state and it represents a 1. In the
dominant state, the SBL wire is pulled down to 0V, and this represents a 0. Note that the transmitting circuit will not achieve 0V;
1V is more likely.
Of course, the recessive and dominant states are simultaneous on both wires.
To summarise:
The recessive state is typically represented by SBH = 0V, SBL = 5V. The recessive noise margin is 5V, and impedance
(oversimplified) is 135 ohms.
The dominant state is typically represented by SBH = 4V, SBL = 1V. The dominant noise margin is 3V, and impedance
(oversimplified) is 15 ohms.

So I tried buzzing the connections and couldn't make sense of the results until I discovered that the DWIZ-ADAPT has active components within it, presumably these are level shifters to reduce the 24V connections to a safe level. The DX-HHC works but says that the chair isn't powered, so I guess I have been sold a broken unit or DWIZ-ADAPT.
The RHINO2 programming adapter will plug directly into an off-board charger socket or into the 4-pin Molex Mini-Fit Junior connector with the use of the AMP programming adapter.

So my issue is probably just having a blue adaptor instead of an orange one?

This adapter MUST use a win chip head CH340/341 or HL340 NOT a Prolific chip.
You will see 340 embossed on the RS232 end of the cable.
