Cambridge 640A V2 with DAC module Musical Fidelity V-Dac V1

[rhdd]

Hello

I modified my amplifier Cambridge 640a V2 & I install inside the amplifier a dac module from Musical Fidelity V-Dac V1 (Usb-Optical-Coaxial Inputs)
I need space for this Dac and I remove the A-Bus PCB Board, and I disconnect on Input PCB Board, connectors CN9 and CN10 (From A-Bus PCB Board)

The amplifier working fine, but like you, the remote control is not working !!!!!!

I am not a specialist of electronic systems
Do you have a solution to solve may problem, because I saw in the past you have same trouble
Let me know
Regards
