The DS2000 is not too different then the DSX. You can use the DS2000 cards in a DSX.

If you get the programming cable and have a laptop it is would be a piece of cake to a DSX person.

The software is essentially the same as the DS1000 software.

The only issue I see is if it is a hardware problem, but of all of the DS2000s I put in I have never had a card go bad. I have only had the intramails go bad
