16 Device Information and Setup
Configuring Serial Communications
MENU → SETUP → RS-232 Serial or RS-485 Serial or Serial Comm
You can operate the flow meter remotely via its data connection for easy streaming and
logging of all data. Before connecting the flow meter to a computer, ensure that it is ready
to communicate with your PC by checking the options in this menu.
For more on how to issue commands from a computer, see page 18.
Unit ID
SETUP → RS-232 Serial or RS-485 Serial → Unit ID
The unit ID is the identifier that a computer uses to distinguish your device from other, similar
devices when connected to a network. Using the unit ID letters A–Z, you can connect up
to 26 devices to a computer at the same time via a single  port. This is called polling
mode (page 19). Unit ID changes take eect when you select SET.
If you select “@” as the Unit ID, the flow meter will enter streaming mode when you exit
the menu (page 19).
Modbus RTU Address
SETUP → RS-232 Serial or RS-485 Serial → Modbus Address
The Modbus address is the identifier that a computer or programmable logic computer (PLC)
uses to distinguish your device from other devices when connected to a Modbus network.
Values of 1247 are available for use.
Baud Rate
SETUP → RS-232 Serial or RS-485 Serial → Baud Rate
Baud rate is the speed at which digital devices transfer information. The flow meter has
a default baud rate of 19200 baud (bits per second). If your computer or software uses a
dierent baud rate, you must change the flow meter’s baud rate in the BAUD menu to ensure
they match. Alternatively, you can change your computer’s baud rate in Windows® Device
Manager. Baud rate changes take eect once you press SET, but you may need to restart
the software for it to recognize the change.
