For additional programming instructions for the faceplate buttons, see Chapter 5 in the
Shark® ST40
Meter Installation and Operation Manual
, (see page QS-1 for the download link).
In addition to faceplate programming, you can program the meter using CommunicatorPQA
TM
soft-
ware. Use either the RS485 port or the USB port to make the physical connection to your PC. Note that
your meter will have either RS485 OR Ethernet; it will always have a USB port. For Ethernet communi-
cation, connect first via the USB port and then see the ST40 User Manual for instructions on setting up
Ethernet communication.
Connect through the RS485 Port:
The ST40 meter’s RS485 port uses standard 2-wire,
half duplex architecture. When the meter is powered
up, for 10 seconds you can connect to it using the fac-
tory default settings - this is one way you can always
connect to the meter. The factory default settings are:
Device Address:1
Baud Rate:9600
Protocol:Modbus RTU
Connect through the USB Port:
The ST40 meter has a standard Micro USB port. Con-
nect the meter to the PC, using the USB cable. The meter’s connection uses a Micro USB plug.
