I built the interface for my Aladin, and the bits were small enough to fit inside the case of an over-size 9-pin D-Type connection. The other option is RS (or Maplin) do little ABS enclosures which you could use (about the size of a small TV remote control).
Try this bit on the RSWWW web site; http://makeashorterlink.com/?T56B3298
(The URL is huge so I've used makeashorterlink)
Hope this helps.
Bollocks. The RSWWW site times out (so you probably saw nothing?).
Go to; http://www.rswww.com
Click 'Electrical' in the All products submenu
CLick 'Enclosures - Metal and Plastic'
Click 'Hand Held Enclosures'
And you're there. The one I thought may be useful is the Large Smart case with the cable gland - and could build the suunto interface into the top of the case.
Here's the URL for you all; http://www.muenster.de/~matthias/aladin/building.htm
I built the interface like shown, and I have tested it on;
Aladin Pro Nitrox
Aladin Ultra Pro
and it works. He also has a link to the software.
Note - the communication happens between when you choose logbook mode and when the 1st dive appears. If it's all connected, you put the PC into read mode, change the Aladin into logbook and select the 1st dive. The aladin will pause for a second and the PC will read the dives in.
You must make sure that your PC time is 100% OK as it uses the current time to adjust back to the dives stored (they're stored as being current time minus x seconds)
Also, your dives abroad will need to have time adjusted as it will assume all dives are local.(but all these downsides happen with the memomouse too).
The windows software won't read from the interface, but the DOS one will, so use the DOS one to download the dives, and then open the logfile in the windows one.
