Breakout cable schematic for Pulsar 2

[bimole]

Hi,

I've purchased a Pulsar II without the breakout cable for the 26 pins high density sub-D.
I'm looking for builing my own one.

I've found this :

It seems there are 2 possible breakout cables, one with balanced XLRs and one with unbalanced RCA plugs.
How can I identify the right version corresponding to the daughterboard I have ?
On this daughterboard are 2 NE5532 opamps (for line IN and OUT probably), the AK4524VF 24bits/96kHz CODEC, an SN75179B differential driver (probably for AES/EBU), a CNY75B opto (probably for the MIDI current loop), and a "big" QuickLogic QL4009-0PF100C FPGA.

Maybe both cable versions are working ?

Your help is very appreciated !

Hi,

Thank you so much for the link!
Here is a picture of my I/O plate :

From the information in the related topic, that should be a classic I/O board, corresponding to the RCA/unbalanced breakout cable.
The proper wiring should be this one :

Am I correct ?

yes, i believe so. that uses the "project" cable pinouts on the page you linked.

I‘d like to add your photo to the other topic, so we have pictures of both types there. Is that ok?

[bimole]

Yes, absolutely no problem. Hope it can help other people
I will post other picts when the cable will be made and working.
