WHY UPDATE THE STANDARD?
The revised specification will result in improvements and enhancement to the existing 1451.2-1997 standard so that future implementation of the standard will be easier and less expensive to accomplish and provide additional capabilities not included in the original standard. Changes will include the addition of alternate physical layers to utilize existing, widely available, low cost data transfer methods in order to reduce the cost and complexity. Additional enhancement suggestions to this standard will be evaluated in the working group and included as appropriate. Furthermore, various corrections, identified by users since the original publication of this standard, will be included in the revised standard as appropriate.
