TTx2 + Sega JVS I/O

[jkl]

Hi, I happen to have 2x Sega JVS Type 2 I/O, that are correctly recognized by Naomi and both seem to be in good working order.
But I'm not able to get them working with my TTx2 setup.
It's not a game problem, the TTx2 stop booting throwing a "No JVS I/O board found" and then suggesting me to connect one and restart.

The exact same TTX is perfectly working with a Sega Type 1 JVS I/O.

Is there anything I could do to set it properly or I'm fighting against an incompatibility?

Thanks to everyone who will answer.

Do you have a picture of the Type 2 Sega JVS I/O?

You will get that error if the system doesn't get a response from the I/O board. It could be an incompatibility but more than likely there is something else going on.

Sure, here it is.
To get it working with my naomi setup I just have to disconnect the jvs cable from ttx and put it into naomi.
Same I/O, same cable, same AC/DC adapter.

Thanks Niko!

Don't know if it's relevant, but I/O card is powered by external 5v only, no 12v rails.
It goes straight into the input card of ttx, the one with usb labeled jamma, rj port, 2 leds and 5 dipswitches.
1, 2 and 5 are on.
Just tried again: jvs type 1 goes hassles free into multi, jvs type 2 no I/O board error.

Thanks

Just curious why you are using this I/O Bd rather than standard JVS. We only used this I/O Bd with games that used a motor drive system to inface with that system.

I'm going to say this is probably just not compatible.

Many thanks guys!

@irepair Sega
Truth be told it has not been a "choice", my lack of knowledge and information led me to aquire those boards in the early beginning of my true arcade journey.
There's somewhere a comparative table / compatibility chart for I/O boards?

Can you take a picture of the JVS test screen on the NAOMI with your IO board connected so we can see what this device identifies as ?

Sure! Thanks!
Here they are (2 similar boards with same layout but clearly differently identified).

Thank you for those pictures, the capabilities look ok, must be something else which is going on.
