MODBUS Parameters
(Not required unless MODBUS is utilized)
There are 4 items of information that may be entered on
this screen. They are baud, parity, framing mode, comm
port designation, figure 52.
• 1st press the Enter / Select key and the baud rate
window will begin to flash. Next use the Up Arrow or
Down Arrow key to increment the value to the
required baud rate of your Modbus system. Available
baud rates are 1200, 2400, 4800, and 9600.
• Next press the Enter / Select key and the parity
window will begin to flash. Next use the Up Arrow or
Down Arrow key to increment the value to the
required parity of your Modbus system. Parity options
are odd, even, and none.
• The 3rd pressing of the Enter / Select key will bring
you to the framing mode window will begin to flash.
Next use the Up Arrow or Down Arrow key to
increment the value to the required framing mode of
your Modbus system. Available options are: RTU or
ASCII.
• The final time you press the Enter / Select key, the
comm port selection can be made. The N-300 has two
comm ports. Use the Up Arrow or Down Arrow key
to increment the value to select one of three options:
MODBUS Parameters
. . No Comm Port is used for Modbus;
ONLY Comm 2 is avaailable for Sentry4
1 . Comm 1 will be used for Modbus; and
Comm 2 is available for Sentry4.
1 2 Both Comm 1 & Comm 2 will be used for Modbus;
NO Comm is available for Sentry4.
Conclusion
This concludes programming the N-300 controller in
Proportional-to-Flow Mode. If this NJEX System is the
only unit that will be initialized at this time,
Section 7,
page 39 , Calibrating Signal Inputs, will contain the next
appropriate information on the NJEX 7300 based on
Proportional-to-Flow Mode operation. If other NJEX
units will be operating in Proportional-to-Time Mode then
proceed to the following Section 6.
