NT3T80BB Dual Serial Data Interface pack - pack type assignment
Pack Type
NT3T80AA
NT3T80BA
August 2006
SDI port assigned for applications that use an eight-bit data stream (that is,
MDR, SCCS, SMDI). These applications are non-ASCII based and the
equipment outputs and inputs 8 data bits. So the setting of 8-bit data is used
and the parity and stop bit settings match those of the equipment in the
application.
- OUTPUT: all eight bits are transmitted.
- INPUT: all eight bits are received and processed.
Note 4: For TBOS expanded alarm interface 1 start bit 8 data bits 2 slot bits odd
parity.
Note 1: Settings: 1 = ON, 0 = OFF, - = NOT APPLICABLE.
Note 2: At baud rates above 1200, caution should be used when interfacing with
equipment other than man-machine interface equipment. The rate of data transfer
associated with machine-machine interfaces can exceed the buffer capacity of the
I/O system, which can result in loss of data.
Note 3: 2400 baud required for TBOS alarms.
Note 1: Settings: 1 = ON, 0 = OFF, - = NOT APPLICABLE.
Note 2: Set the pack type switch (switch 1) to ON when the NT3T80BB is used
to replace an NT3T80AA. The switch should be set to OFF for all other
applications.
