Modification

The first step is lifting 4 pins which correspond to 5V and GND in the connector (Figure 3), so they
don't supply power to the mainboard of the CHA when the controller is powered on. They can be
lifted by heating the pin with the edge of the soldering iron and pushing with a needle or any other
object with a thin edge.
In the Figure 3, you can see the circle pads on the board, which must be connected to the following
points of the HUB (Figure 4) and the relay (Figure 7). In order to manipulate the relay, I advise
soldering on the bottom side.
[5V] – [K1M]
[GND] – [K2M]
[D1-] – [K3M]
[D2-] – [K4M]
[D1+] – [HD1+]
[D2+] – [HD2+]

Regarding the HUB (Figure 4), the following points must be connected to the ones in the relay (Figure
7). In order to make sure the points with the "In-" prefix are distributed like that on your hub, you
can measure continuity between [Vcc] – [In-Vcc], and [GND] – [In-GND].
[HD1-] – [K3ON]
[HD2-] – [K4ON]
[In-Vcc] – [K1ON]
[In-GND] – [K2ON]
