Dallas 2751 Battery Mngt. IC

Hello,
I am attempting to use a Maxim 2751 analogue-to-digital-converter IC (Dallas 1-wire communication) and a Basic Stamp 2p to accurately track the conditions of battery packs under charge and load conditions. I hope to daisy-chain up to 25 of these 2751's together to simultaneously check 25 batteries. This project is to be integrated into a factory's production line to make sure the batteries being sent out are o.k.
I believe I am reading the 2751's unique device address already.
Has anyone ever seen or written the BS2 code necessary to poll different 2751's (or a 2760) on the same 1-wire buss and get their voltage and current back to the Basic Stamp. I am currently trying to make sense of the 2751's data sheet, but of course there is no examples with PBasic.
I know OWIN and OWOUT commands are the main ones involved, but any example of code I can try to decipher the data coming into the stamp (real-time voltage/current) from the 2751, or a link to somebody's website with any info would be greatly appreciated.
Thank You
