EMU-2
™
Technical Manual
24
This method is particularly useful for implementing dynamic and/or tiered pricing in
deployments where the price cluster has not been enabled in the meters. Note that this
feature is only available as a special factory option.
Meter Input
The
EMU-2
™ issues a GetCurrentPrice command to the meter every 2 minutes. If the
meter responds with a PublishPrice Command with pricing information, this new Price
value will override any value that has been input manually or via text message. This
makes migration to full in-meter pricing transparent and painless.
Serial Port Input
In addition to the three techniques listed above, pricing information can also be
programmed into the
EMU-2
™ through the USB serial port. This allows complex block
pricing schemes, with up to four tiers and programmable block thresholds to be
downloaded to the unit. The details of how to use this feature can be found in a
separate document: the
EMU-2
™ Block Pricing Programming Guide.
