Product Description：
The Serial Data Interface (SDI) and Dynamic Data Interface (DDI) are two distinct microprocessor
interfaces between a host system and a 3300 rack. The Serial Data Interface collects static data
and status values from the monitors within the rack. By using proper third party software, the
values obtained from the rack can be viewed and stored. The Serial Data Interface connects
the rack to an Allen-Bradley computer or Honeywell monitor system. The Dynamic Data
Interface allows a host computer using TDM 2 software to obtain static data, status values, and
steady state dynamic data from the buffered transducer outputs of the monitors within the rack.
The SDI and DDI are options available with the 3300/03 System Monitor.
The SDI and DDI are
located within the System Monitor slot of the 3300 rack. The DDI option also includes the SDI
option, but the SDI is available as a separate option. The system can function simultaneously as
a SDI and DDI.
