the analog signal from each smart transmitter goes to an indi-
vidual input channel (point-to-point). Because the inputs are
analog point-to-point, the FBS module can interface any com-
bination of devices while it is in this operating mode. For exam-
ple, in addition to FSK smart transmitters, baseband smart
and conventional transmitters can input process data but can-
not communicate with the FBS module. The NTAI05 termina-
tion unit or NIAI04 termination module provides point-to-point
termination. Dipshunts select the type of input signal for each
channel. Function code 133 must be configured in the MFP or
MFC device for every five analog inputs from each FSK device.
Baseband Analog Point-to-Point Mode
The baseband analog point-to-point mode emulates the opera-
tion of the IMASI02 Analog Input Slave Module, which was the
predecessor to the FBS module. When operating in this mode,
the FBS module can interface any combination of Bailey -Fis-
cher & Porter FSK smart transmitters, baseband smart trans-
mitters, conventional transmitters and other analog inputs.
The FBS module inputs analog process data point-to-point and
communicates to the baseband smart transmitters (Fig.
Examples of these transmitters are the BC smart pressure
transmitter, EQ2 smart temperature transmitter and smart
pH/ORP/pION transmitter. The NTAI05 termination unit or
NIAI04 termination module provides point-to-point termina-
tion. Dipshunts or dipswitches select the type of input signal
for each channel. Function codes 132 and 133 must be config-
ured in the MFP or MFC device for every five analog inputs
from each baseband transmitter.
