• Remove the meter from service prior to installing the antenna isolation kit and/or remote external
antennas.
• Be aware that dangerous voltages exist at several points within the meter when this product is installed on
a meter socket.
• Always disconnect power before meter disassembly, soldering, or replacing components.
The S4e meter is connected directly to line potential. Due to the possibility of the potential lines being reversed,
points accessible with the cover off may be at line voltage.
LINE POTENTIAL IS PRESENT ON THE INCOMING CONNECTORS ON THE MEASUREMENT BOARD
INCLUDING THE BATTERY CONNECTOR.
The connectors have full-length insulators crimped onto each connector, which are shielded by the housing.
However, pulling the connector loose will expose the battery terminals, which may be at line potential. The option
board is connected directly to the main board and may be at a high potential. A Mylar shield prevents touching the
option board. Removing the Mylar shield exposes line voltage. The above warning label affixed to the meter
frame identifies hazards in the meter.

Introduction
The S4e Cellnet endpoint brings accuracy, reliability, and low-cost wireless communications to polyphase metering
applications. Leveraging the Cellnet Solid-State Meter Module (MFMM), the S4e Cellnet endpoint transmits 5
minute interval data with 4x redundancy. Some highlights of the S4e Cellnet endpoint are:
• Reliable polyphase AMR
• Advanced metering capable (Demand, TOU, LP)
• Under-cover wireless communications
• Tamper detection
• Outage notification
• High reliability and accuracy
• Field proven
• Economical price
System Overview
The Cellnet MFMM is a one-way radio frequency communication device that broadcasts using direct sequence
spread spectrum technology over the unlicensed 902-928 MHz frequency band. The Cellnet MFMM also
incorporates an interleave broadcasting technology. Every five minutes, it broadcasts a higher power signal that
carries for about ¾ of a mile. Between these broadcasts, the MFMM also broadcasts every four seconds at a
reduced power that carries for 1,200 feet.
Data can be collected in two ways. The first way employs a drive by solution known as Forerunner. With the
Forerunner solution, information is collected using a receiver that is transported using an automobile. The receiver
is capable of collecting both low power and high power signals, and is designed to be transported up to 30 MPH. If
a customer base becomes dense enough, the Forerunner solution allows for the upgrade to a fixed network.
With a fixed network, the Cellnet MFMM transmits static data and meter data to the Infinet Gateway(s). The
Gateway acts as a concentrator and retransmits information to the Infinet Take-Out point (TOP) point via a WAN,
where it can be moved to a secure IP network.

The Cellnet MFMM transmits static data (ID, type, address, etc) and meter data to the Infinet Gateway(s). The
Gateway acts as a concentrator and retransmits information to the Infinet Take-Out point (TOP) point via a WAN,
where it can be moved to a secure IP network.
This is similar to Landis + Gyr’s Forerunner solution. With the Forerunner solution, information is transmitted from
the meters much in the same way. However, information is collected using a receiver that is transported using an
automobile. If a customer base becomes dense enough, the Forerunner solution allows for the upgrade to the
fixed-point receivers.

S4e Meter Overview
All S4e meters include wide-dynamic voltage application capability, forms reduction, Service Scan automatic service
recognition, and GyrBox installation diagnostics and monitoring. The S4e is available with several register types,
providing the right functionality for any metering application. The S4e Cellnet MFMM can be ordered with the
following register configurations, however they can not be accessed using the Cellnet MFMM:
AX Active energy, Demand or TOU
AXR 32K Active energy, with a 32K byte load profile recorder
AXR 128K Active energy, with a 128K byte load profile recorder
RX Active and reactive measurement, Demand or TOU
RXR 32K Active and reactive measurement with 32K byte load profile recorder
RXR 128K Active and reactive measurement with 128K byte load profile recorder
An optional input/output board provides up to 2, form C, solid-state relays and up to one external inputs for recording
pulses from a remote source. The 4 relay option board is not available with the S4e Cellnet MFMM meter. One
external input can also be used for real-time rate changes or self-read actuation. The board can be easily added in the
field without the need for special tools or soldering.
For additional information on the S4e meter, consult the
S4/S4e Solid State Meter Instruction/Technical Manual.
Cellnet Module Overview
The S4e meter is modular in its design. The Cellnet MFMM occupies the communications board slot in an S4e meter.
<Insert Cellnet MFMM Picture>
Configuration of the Cellnet Module
The S4e Cellnet MFMM meter is programmed using 1132Prog/1132Com. The Cellnet MFMM module is factory
programmed with a unique LAN Address. It is programmed using RadioShop either serially or over the air.
Meter Setup
The Cellnet module relies on certain inputs from relay 4 for its operation. As a result, there are a few minimum
programming requirements for the S4 (using 1132Prog). The load control relay activates the relay upon power
up. This relay triggers the Cellnet MFMM module to power up. If the meter is not programmed as shown below,
the Cellnet MFMM module will not power up. A special tool, Cellnet MFMM Radio Tool, was developed to query
and reboot the Cellnet MFMM module.
Relays:
Set Relay 4 to Load Control (“LC”), “Used” in Normal Mode and Normal Off State to “Closed”.

Meter Installation
Step 1. Installing S4e Cellnet MFMM Meter
If existing meter is present, follow company procedures for meter removal and installation. (Note: Meter removal
and installation should only be performed by a properly trained technician.)
When the radio is reading information from the meter, the S4e will flash P/R on the display, as shown below.
Step 2. Verifying the S4e Cellnet MFMM Communicates Over the Network

Use of External Antennas
S4e Cellnet MFMM equipped meters are manufactured with an internal antenna. However, some meter locations
have less than optimal RF reception. Many meter services are ungrounded. Examples of these types of services
include single-phase form 2S, as well as floating 3-wire delta services, 12S and 45S/5S. To improve the reliability
and safety of these floating services, Landis+Gyr has developed an interface for remotely mounted antennas that
allows RF reception under these service conditions. The High Voltage antenna coupling system protects Cellnet
MFMM components from transients reaching up to 7,000 volts. The Landis+Gyr External Antenna Isolation
Solution needs to be installed in the S4e meter in accordance with Landis+Gyr Specifications. Contact the factory
for more information regarding ordering and installing approved external antenna solutions. See the diagram on
the next page. THIS IS FROM THE UTILINET MANUAL. I AM UNSURE ON HOW THE CELLNET’S ANTENNAS
DIFFER.
