BACnet Diagnostic Utility
The MS/TP ReadBack diagnostic utility is provided as a helpful
tool to verify connection between the Model 340BN transmitter
and BACnet
network when installing a transmitter or while trouble-
shooting faulty communication between an individual node and
the master controller. To use this utility, the Model 340BN trans-
mitter must be connected to a PC or laptop and the BACnet
network as outlined below.
1.
Connect the PC to the Model 340BN transmitter using
the Badger Meter Model A301 communications cable.
Plug the RS232 connector on the Model A301cable to
the 340BN socket labeled D.I.C. Comm Port, taking care
to properly align the tab on the plug and socket to main-
tain polarity. Plug the DB9 connector on the opposite
end of the Model A301 cable to an available PC com-
munications port. If a cable with a DB9 connector is
not available, a USB to DB9 adapter (e.g. IOGEAR
GUC232A) can be used.
2.
If not already installed, connect the Model 340BN trans-
mitter to the BACnet network. Connect all three Model
340BN network terminals (+), (-), and REF to the
BACnet buss if the transmitter is the final node in a
given network. Otherwise, connect only terminals (+)
and (-) to the BACnet buss. Confirm the correct posi-
tion of jumpers on the Model 340BN transmitter. For
the final transmitter in a given BACnet network, NT, PU,
and PD jumpers should be in “open” position. Other-
wise, NT, PU, and PD should be in the “closed” posi-
tion. Please refer to the Sample Wiring Diagram to
BACnet Network found on page 5.
3.
Open the Badger Meter Combo PC Software.
4.
Follow steps 5 through 7 found on page 6 to open the
Model 340BN Main screen.
5.
From the Main screen, select MS/TP ReadBack.
This will open the MS/TP Check screen as shown below.
