Notes:

  1. Part number in bold are McAir compatible.
  2. Direct Coupled (Short Stub): Transformer to be used when Stub distances to Data Bus are 1 foot or less.
  3. Transformer Coupled (Long Stub): Transformer to be used when Stub distances to Data Bus are 20 feet or less, also requires the use of a coupling transformer. (1:1.41 ratio)
