This section provides brief descriptions and procedures for:
• Communicating with the meter
• Programming the meter (firmware)
• Resetting the meter
• Replacing meter components
Meter Communication
Linking with meter is accomplished by various means. This section provides brief descriptions of
the means to communicate with APX meters for data transfer, programming and configuring,
and meter updates.
To communicate with APX meters, use an ANSI Type 2 optical probe with any of the equipment
listed below.
• Laptop or Work Station with a Microsoft Windows operating system and loaded with
iConFig or some other software for communicating with electricity meters
• A supported hand-held device used to read billing information from meters.
Infrared Port
The infrared port was designed to accept an ANSI C12.18 Type 2 optical probe. The port can
communicate up to speeds of 19200 bps, and complies with the protocol specified in the ANSI
C12.18-1996 standard.
Remote Communications
Installing an optional AMR Module enables remote meter communications. For more
information, refer to the documentation that came with the AMR Module.
Updating the Firmware
The firmware is stored in flash memory and can be easily loaded into the meter through its
optical port. If it becomes necessary to update the meter’s firmware, Sensus Metering strongly
recommends that all billing and meter data be backed up prior to the installation process.
To update the meter’s firmware, an Action can be created and executed using iConFig. Refer to
iConFig Start-up and User’s Guide for instructions on performing a firmware upgrade.
Resetting the Meter
It may be necessary to reset the meter:
• In the event that a meter is malfunctioning or fails to perform as programmed and/or
configured
• After removing a meter from service (depending on the standard procedures of the utility)
