DCS Loader not working on my MAC

What version of Parallels are you using? Is it fully Snow Leopard compatible?

Barry, Its version 6, a little over a year old. I find it weird that the serial port utility has no problem seeing the TIU but not when trying to download to it. The DCS set is only a few months old and has USB. The serial utility sees the TIU if I use USB to USB or USB to serial port through an adapter.

I had a similar issue with real Windows.  My Rev. L TIU was recognized using the serial port, but I couldn't load anything.  The USB interface worked fine, so that's what I use.  The same serial<->USB adapter worked fine for my Legacy command base.

Hi Pete,

My laptop has a VERY similar configuration.  MacBook Pro with Snow Leopard running Win XP in a virtual machine with Parallels 6.  The loader software works fine on my system with both USB to Rev. L TIU's and USB->Serial adapter for all other TIU's.  It will work fine once we get you set up properly.

What process are you attempting when the loader software fails to find the TIU?

If you have a bad telephone cable connection while trying to load firmware on the remote the loader software will act like it can't find the TIU even though the TIU connection is fine.  Even if your TIU is already updated to v4.20 I suggest trying to re-load the TIU firmware.  That's the simplest process for the DCS loader software to perform and it will test the TIU connection without any other complications.

Dave, I was wondering if the telephone cable might be the problem. Its one I had laying around but not used to do updates with. It has 4 wires on both ends but they are mirror images of each other 1 to 4, 2 to 3, etc. Is this how they should be wired or should it be 1 to 1, 2 to 2? Not easy prying this info from MTH. BTW I was first trying to update to 4.2.
