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

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
dierent 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 eect once you press SET, but you may need to restart
