At one time the Casino Floor was Daisy Chained (The SDS lines came from MIS to a bank of games then to the next bank of games. Without an up-to-date map of the SDS lines on the floor, Troubleshooting SDS problems were very hard and time consuming.

Now most of the Casino Floor is Daisy Chained in the SDS boxes. Helps to reduce the time it takes to troubleshoot the lines. In one location you have access to the entire SDS line. Easy to isolate down to the bank of games, without having to wait and or tie-up security.

In the Slot Shop is a book describing the SDS Lines and the SDS Boxes, and where the SDS boxes are located.
