I have a use case where the clients drivers will need to be able to plug in their iPads to DEX enabled vending machines and pull a DEX file. Motorola cells a bunch of hand held devices to do this. We want to be able to do it with the iPad if possible. The standard cable is RCA jack to Serial portconnector. I know we can get a serail port to iPad connector but not sure how we would be able to send a recive to the machine. The DEX file format is open source. Has anyone done this or anything like it. Any ideas? Guess maybe we could write an IOS application to do this and grab data from it. Really not sure where to look next.
