Hi, I got an CDTV keyboard recently which I want to connect to my DBox (w/PCKey 1200).

I searched a lot before I post here but didn't find 100% the accurate conversion.
I know for sure (from websites+BBOAH) that the PS2 connector of CDTV pinout is this:
- 1: Ground
- 2: Data
- 3: Clock
- 4: +5V
- 5: Unused
- 6: Unused

What is the correct rewiring for me to perform in order to make it work?

I found an article about CDTV to CD32 rewiring...

To modify the CDTV keyboard to connect to the CD32...
- Cut the plastic pin from the connector.
- Open the case.
- Find the connector where the cable is located.
- Switch leads 1-4 and 2-3.
- Close the case.


...but I don't know if CD32 keyboard is same as 4000 meaning it should work just fine as it is with PCKey1200.

Cheers

I thought the cdtv keyboard is same pinout as an a4000 keyboard ???

both use a 6pin mini din, the CD32 is different as it also has serial signals in its AUX port

The CD32 keyboard & A4000 Pin out are identical & according to the BBoAH the Interface can accept PC or Amiga Keyboards, I think you just need to mod the wiring as you've stated from CDTV to CD32 & it should be fine. & use a std PS/2 to 5 Pin Adapter (PC type is fine)


:D

Thanx mate, I'll try the rewiring that I wrote once I receive the keyboard and will report back.

TheCorfiot is right though. In BBoAH the pinouts for CD32 and A4000 are identical so I think it will work.

Of course the A4000 does not have the serial connections as my good friend Zetro pointed out.

I would dig a little deeper regarding the CDTV mod to CD32, pin out, check out Finger's thread (see at bottom of this screen), he seemed to acomplish the mod by just resiting 1 connection???

Importantly though just don't get the +5V/Gnd connections wrong, other misconnections will not cause damage but +5V to the KB on the wrong pin could fry it.


BTW why not use a nice modern Cheap PC Keyboard seeing as you have the Interface converter?

Just for informational purposes...

The rewiring that I read and performed works like a charm...
Just rewire 1 with 4 and 2 with 3 on the keyboard connector (inside of keyboard) and you're done.
