Transmission Modes
The Cellular 500W pit module is an IPv4/IPv6 compliant device that operates in Mobile Mode or
OpenWay Riva Network Mode.
In Mobile Mode, the module transmits every ten seconds over multiple RF channels to report on:
■
meter register value
■
cut cable or communication error events or alarm(s)
■
reverse flow (encoder version selected)
■
system leak status
■
low battery indicator
In OpenWay Riva Network Mode, the module supports a configurable interrogation cycles daily.
Each interrogation collects hours of interval and event data as a function of the programmed
configuration.
Note: Interval data functionality is dependent on the module's firmware version. For more
information, see Firmware Functionality on page 13.
The Cellular 500W module also sends a local access beacon message every 60 seconds that
allows users to gather contingency readings locally when needed.
Caution: If you perform a Switch to OpenWay Riva Network Mode or Switch to
Mobile Mode operation, it results in a loss of interval data.
The Cellular 500W module operates using FCC licensed spectrum defined by 3GPP ranging
from Band 4 (744-787 MHz) and Band 13 (1710-2155) operation 612054.
Operating Modes
The OpenWay Riva pit module has the following operating modes.
1. Factory Mode
–
Pit modules ship from the factory in Factory Mode.
–
The pit module's transmitter is off.
–
The pit module's receiver listens for a programming command.
–
The pit modules attempt to read the register every hour.
–
Last Good Read and Extended event or alarm flags may be set when a register is not
connected.
–
If the pit module reads a connected register, the pit module automatically switches to
Run Mode.
