The driver manual is incorrect. For your device, the default driver that comes with OS X does not contain the appropriate information. You need to install it.
The default one contains info that lets certain devices work, however this does not include any of the dive computers. So, the solution is to just install the driver off their website, which does contain that. It's a little annoying that Apple didn't include support for all of the devices, but it's easy enough to fix.

Thanks Nick! I installed the driver and it worked.
