Typically, the largest component in a system is the data logger box. This photo is a 38-channel professional system; however, it is relatively compact and only weighs a few pounds. A weekend racer may have a similar box size but only have one fourth of the cables connecting to the box. This team developed an aluminum plate that is quickly attached to the rollcage with hose clamps. The rubber feet under the box assure a long and trouble-free life for the logger.
