1.7.5 Resetting Totals via the Network

Totals are held in non-volatile memory within the display. Each total (ow or auxiliary

input) has a corresponding output variable that transmits the information from the display

to the network. There are two ways to remotely reset totals in the display. This can be

done using individual input variables to command the display to reset specic totals or it

can be done using the nviRequest variable. Using nviRequest allows you to reset each total

individually or all totals simultaneously with one command. See sections 1.7.3 and 1.7.4.1

for specic instructions on how to reset totals.
