Wasn't too sure where to put this post so sorry if its in the wrong place

I have the VEO Wireless Observer Camera. The only way to set it up is using the RS232 serial cable.
I dont have it

The cable has a 3.5mm male jack plug on 1 end and he RS232 on the other end.
I have bought 1 cable but it does not work so i am assuming its a specific cable for the camera i.e.
the wiring for the pins must be different to what i bought.....
I am hoping that someone here might have a broken VEO and still has the cable, failing that, if it aint
broke, or you just dont want to part with the cable, then perhaps you can assist with making a pin
wiring diagram for me?
I know its a very long shot but i have tried everything else i can think of, including contacting VEO but
it looks like they have closed down, even eBay has turned up a blank, although thats where i bought
the serial cable from, but it was for a ICOM scanner, that was another longshot
