Installation Guide

Note: Interval data configuration is dependent on the module's firmware version. See
Firmware Functionality on page 13 for more information.
The Cellular 500W remote 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 remote module operates using the 902 to 928 MHz in the ISM band
frequency band and does not require an FCC license.
Operating Modes
The Cellular 500W remote module has the following operating modes.
1. Factory mode
–
Cellular 500W remote modules are shipped from the factory in factory mode.
–
The module's transmitter is turned off.
–
The module's receiver is bubbling-up to listen for a programming command.
–
OpenWay Riva remote modules will attempt to read the register every hour.
–
Register Error Detected and Register Error alarm or event flags may be set when a
register is not connected.
–
If the Cellular 500W remote module reads a connected register, the module
automatically moves to run mode.
2. Audit Mode
–
Audit mode reduces the normal read latency time associated with standard modes of
operation and is often used after initial installation.
–
This mode is useful in Riva network installations where the normal bubble rate is very
slow.
–
Audit Mode remains active for 30 days and then reverts to the initial programmed mode.
–
Audit Mode is intended to be used once.
3. Run mode
–
OpenWay Riva remote modules normal operation mode.
–
The module's transmitted message is dependent on its factory settings for standard
consumption + messages (SCM+).
–
SCM+ Cellular 500W remote module default bubble-up rate is 10 seconds.
