FCC Notice
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interfer-
ence by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
RF Exposure Information
This equipment complies with the FCC RF radiation requirements for uncontrolled environments. To maintain compliance
with these requirements, the antenna and any radiating elements should be installed to ensure that a minimum separation
distance of 20cm is maintained from the general population.
Professional Installation
In accordance with section 15.203 of the FCC rules and regulations, the MIU must be professionally installed by trained utility
meter installers. Changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.

Industry Canada
This Class B digital apparatus meets all requirements of the Canadian Interference Causing Equipment Regulations. Opera-
tion is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
Cet appareillage numérique de la classe B répond à toutes les exigences de l'interférence canadienne causant des règle-
ments d'équipement. L'opération est sujette aux deux conditions suivantes: (1) ce dispositif peut ne pas causer l'interférence
nocive, et (2) ce dispositif doit accepter n'importe quelle interférence reçue, y compris l'interférence qui peut causer l'opéra-
tion peu désirée.

Enhanced E-Coder)R900iInstallation and Maintenance Guide 1
1 Product Description
This section provides a general description of the Enhanced E-Coder®)R900i™ register
(subsequently referred to as E-Coder)R900i). The E-Coder)R900iby Neptune is an inte-
grated register that contains both the E-Coder®and R900®technologies in one register that
collects meter reading data. It then transmits the data for collection by the meter reader. A
Neptune walk-by, mobile, or R900 Gateway fixed network data collection system receives
the data and stores it to be downloaded into the utility billing system for processing.
The E-Coder)R900iis easily installed and operates within an RF band which does not
require an operating license. The E-Coder)R900imeets FCC regulations part 15.247
allowing higher output power and greater range. The E-Coder)R900iuses frequency-
hopping spread spectrum technology to avoid RF interference and enhance security. The
transmitted data is updated at 15-minute intervals and transmits a mobile message that
includes the meter reading data and the unique 10-digit E-Coder)R900iID every 14
seconds. This allows the meter to be read by a handheld unit (HHU) or mobile data
collections unit. The E-Coder)R900ialso transmits a high power fixed network message
every seven and one-half minutes on an interleaved basis to an R900 Gateway.
The E-Coder)R900iis designed to offer advantages to utility organizations of all sizes:
• Increases meter reading accuracy
• Eliminates hard-to-read meters
• Protects utility liability by increasing meter reader safety
• Requires no external wiring or programming
• Provides enhanced 8-digit AMR meter reading
• Provides proactive customer service benefits (leak, tamper, and backflow detection)

Product Description
2 Enhanced E-Coder)R900iInstallation and Maintenance Guide
E-Coder)R900iProgramming
The E-Coder)R900iis NOT field-programmable. At the factory, each of
the following items is programmed into the MIU:
• Serial number - Each MIU is given a unique 10-digit serial number/
identification number.
• Meter size and change gear information.
RF Protocol Error Detection
The RF protocol is comprised of a header, data packet, and an error
detection mechanism that reduces the erroneous data.
RF Frequency Control Algorithm
The MIU's frequency-hopping spread-spectrum has a sequence of at
least 50 different channels for transmitting data. Associated with the 50
channels are 50 frequencies that are pre-selected in a pseudo-random
manner. These 50 frequencies are coded into the software.
RF Transmission Period and Randomness
The random period generation uses the same random seed created for
the channel definition to generate the transmission randomness. The
randomness algorithm is defined so that no two consecutive
transmissions from two MIUs interfere with one another.
Inside and Pit Versions
The E-Coder)R900icomes in a pit version with a roll sealed metal body
and the inside version comes in a laser sealed plastic body.

3 General Installation Guidelines
This section describes tools, materials, and general installation information for the
E-Coder)R900i.
Tools and Materials
Table 1 shows the recommended tools you need to successfully install the
E-Coder)R900i.
Safety and Preliminary Checks
Observe the following safety and preliminary checks before and during each installation:
• Verify that you are at the location specified on the site work order.
• Verify that the site is safe for you and your equipment.
• Notify the customer of your presence, and tell the customer that you need access to the
water meter.
• If the site work order does not have an MIU ID number on it, write in the ID
number(s) of the MIU you are about to install. If the site work order already has an
MIU ID number on it, verify that it matches the ID numbers on the MIU you are
about to install.
It is possible that some items do not apply to your specific installation, or the list does not contain
all required tools or materials.
