help to connection sega alls to an aime card reader

[naunaure]

Hello,

I just bought a sega Alls . When starting the Alls, i had to first replace my I/O 3 with a I/O 4 because the card does not continue loading.
My first question :
Do you know out of the three I/O leds, one is flashing ?

Now, i encounter a second and final error.
The Alls system must be connected to an AIME reader.

I got one but my problem is connecting the Alls to this reader AIME.
If anyone can !!give me some guidance on the wiring..

I know I have a connection with THX ...., and I think the red is powerboat how many volts ?

thanks for you replies..

So, I answer myself...

I wired the player in 5 volts, a red LED lights up inside, then, I wired the wires as explained in a post that I had on arcade project but the player is still not recognized..anyone have an idea?
Bad wiring, poor power supply,...
