Foil keyboard fail

Another problem happend....
The keyboard foil for roland R706+Lv is not working at all
But when i tried on another machine it worked normaly
It is because the mms is not installed yet or another cause
I sent the CPU picture, and can anyone explain what the green light mean ( in red circle )
Any sugestion

Nb : is the orange light code for mms not actived

 

Hi sir;

Please measure carefully the Regulated power Supply in tolerance, otherwise, will NOT work.

 

The keyboard has no connection to the MMS. It works with it and without it. The green LED in the picture is on the communication board. Token ring. I'm sure you don't have a network set up between the machines. This diode has no connection to the keyboard.
The keyboard may not work if:
1 It is not connected to COM1
2. There is no 5V power supply
3. The driver is not loaded.

 

Can you tell me the name of the driver is and where i can find

 

The driver is installed automatically during the console software installation.

 

Maybe because i havent installed the sps-mms config..??? ( disk in picture attach )

 

Installing MMS SPS is a separate procedure. MMS config alone cannot be installed.
