EMC CX200 SPS cable pinout

Hi, I am using an old CX200 SAN in my VMware lab.  Works fine, but during the last move, the SPS battery sense cable went missing.  It is an RJ12 modular plug to DB9 serial type connector.  I have the shielded RJ12 and DB9 connectors and shielded cable which I bought as I had found the pinout for this cable on google.  Now searching on it, I can't find it again.  If anyone can tell me the pinout of this cable RJ12 to DB9, I would most appreciate it.

well, it can't be the second one as the RJ12 only has 6 pins.  The first one maybe, but as I remember it, there were only about 3 connectionos made between the two connectors.  I have asked on EMC forums so if I get an answer and it corresponds that the first solution would work I will mark your answer as correct.  As I don't want to damage anything, I want to get a at least one confirmation before I wire it up.

Do you still have the cable?

You can reverse Engineer and find the pinout.

You won't do any damage if you get the cable wrong - it just won't work.  I have a copy of this - let me have a bit of a dig.
