Certain available software has built in support for the board. Fritz(most versions) supports the DGT board out of the box. Babaschess - a FICS client - supports the DGT board. DGTprojects also offer support for developers and though it's been some years since investigating (http://www.dgtprojects.com/site/index.php/dgtsupport/developer-info/information), I imagine the resources are quite substantive.
Using the board was at one point the only way my wife could enjoy playing chess since her eyesight is only nominal at best.
It truly does feel like you're playing OTB and making the move for the software on the board becomes second nature after a while. If you can afford it, it's a great investment and will start conversations any time you mention it.
If you decide on one - I would recomend getting the latest edition of Fritz as well or investigate with your retailer for other alternative playing programs.
So, I'm a pretty tech savvy fellow but when it comes to chess I'm pretty lost. I don't have database software or top end chess analysis engines. I've been looking to get a chess table or a new board. The DGT boards blow my mind. Mostly because I see a big gap in my otb play compared to my online play. I think it would be awesome to be able to play on chess.com against opponents with a real board. My question is, what all does it take to get a dgt board to operate with chess programs/ online browser play? Any advice would be well appreciated. (I'm looking at buying the set and board used at the channai Championship.)
