Audio Control
Functions
connected to the
Local BT I/O
card The local BT card was typically used to support the following monitor and control points when
used with audio systems, these points have similar, but not direct functionality on the 4100U/
4100ES.
When these points are encountered in 2120 SMPL programming, they must be re-programmed (or
removed) for compatibility with 4100U/4100ES audio equipment.
