FCC INFORMATION
See Appendix F, CPR Information, for more information.
INSTALLING THE CELLNET PULSE RECORDER
The following includes information about installing the CPR endpoint.
Mounting the CPR
The CPR endpoint should be mounted above ground, outdoors, facing the nearest
concentrator.
Identifying the Register for Installation
Refer to the Gas Module Compatibility Chart for compatibility and specific parts
needed.
Connecting the PRECO Switch to the CPR
Install the PRECO switch on the gas meter index according to the instructions
included with the PRECO kit.
Route the cable from the PRECO switch to the CPR mounting location. Splice
the additional cable as necessary. When using additional cable, always match
colors: PRECO blue to CPR white (via green extension wire), PRECO red to
CPR red, PRECO white to CPR black (via black extension wire).
If you need to add cable for a remote wall‐mounted CPR, follow the
instructions here for removing the Molex connectors (if present) and splicing
additional cable. Prepare cable ends for crimping:
Using the cutting blade portion of the Wire Cutter and Stripper tool, cut
the wire at the Molex connector (if present) coming from the PRECO
switch. The wire attached to the PRECO switch contains three wires.

`ÉääåÉí=mìäëÉ=oÉÅçêÇÉê=jÉíÉê=jçÇìäÉ=fåëí~ää~íáçå
Press and hold the button on the RF Buster. Position the RF Buster less than
six inches away from the left side of the CPR. The RF Buster makes audible
beeps and the LED flashes to confirm transmission of the RF packets from the
endpoint.
Do not use a cell phone or any other RF device while conducting
this test.
If the RF Buster detects packets within one minute, the installation is good. If
the RF Buster does not beep, refer to ʺTroubleshootingʺ on page 7‐9.
Attach the cover using the four screws included in the hardware kit.
Clean the area and remove all disposable materials.
ENDPOINT REPLACEMENT
Please follow the instructions below to replace an endpoint:
Open the face of the CPR.
Write down the color translation.
Carefully cut any tie wraps.
Cut off Scotchloks near the crimp.
Unmount the CPR.
Disconnect the battery.
Proceed to ʺConnecting the PRECO Switch to the CPRʺ on page 7‐5.
TROUBLESHOOTING
RF Buster Does Not Beep When Testing
First, verify that the battery is properly connected, red wire to red wire.
Does the RF Buster beep and light the LED when the switch is initially
pressed? If not, the battery in the RF Buster is dead. Replace the RF Buster
battery, or use another RF Buster.
After activating the magnetic switch on the CPR, hold the RF Buster switch
on continuously. Point the LED end of the RF Buster toward the front of the
CPR. Hold the RF Buster between 6” and 12” from the front of the CPR. Wait
ten seconds. If the RF Buster does not beep, replace the CPR battery.

CHAPTER 9
GAS METER PREPARATION PROGRAM (GPREP)
The Gas Meter Preparation Program (GPrep) is a software tool that facilitates
Cellnet processes. It also runs with water CPR modules. The data captured by
GPrep is sent to RIMS to update the Cellnet and utilities databases. GPrep was
developed for ResGas, C&I Gas (Diaphragm), C&I Gas (Rotary), and CPR (gas
and water) modules to:
•
Disassociate Module IDs from Meter IDs ‐ “MRB (Material Repair Board)
Mode” This feature most commonly captures the record of disassociation
when removing a module from the field.
•
Validate the programmed LAN Address with the Power LAN Address label
and verify that the operational programmed parameters match those
required. ‐ “Inspect Mode”.
This feature is most commonly used when receiving meters from the factory
with Cellnet modules already installed (OEM Meters) or when receiving
Cellnet retrofit modules directly from Cellnet’s manufacturer. Different
utilities use different sampling procedures. The meter shop should verify a
percentage of inbound modules to ensure that the LAN Address that is
programmed into the gas module and matches the LAN Address on the label
outside of the module housing. The modules can also be inspected to verify
that the correct Meter ID format was used, that the rollover point is correct,
and that the meter constant is correct.
•
Program the module with operational parameters, including the meter‐
specific values such as meter ID, rollover point, meter constant, and dial
index reading (which for gas meters can be non‐zero) ‐ “Program New or Re‐
Program Old Mode”.
This feature is used when assembling Cellnet modules on meters in the meter
shop and in the field (for the O&M Processes).
•
Save the inspection, programming, MRB disassociation record and index read
results in separate files for delivery to Cellnet and the utility.
This can be an automatic process or you can turned it off for a particular
feature when it is not necessary to save the results.
Each of these functions are steps in Cellnet processes. You should fully understand how
data flows within the Cellnet network and what data needs to be captured from or
programmed into a module before using this software.
You can use GPrep in a meter shop, at a fixed location, or in the field. You can use
a PC or laptop computer. Closely monitor GPrep usage, and make the data files
easily accessible. GPrep is often used with operations and maintenance (O&M)
`ÉääåÉí=d~ë=jçÇìäÉ=~åÇ=jÉíÉê=fåëí~ää~íáçå=dìáÇÉ
VJN
d~ë=jÉíÉê=mêÉé~ê~íáçå=mêçÖê~ã=EdmêÉéF
processes. This chapter assumes that the user fully understands these O&M
processes, and at which steps in these processes GPrep captures data and
programs it into Cellnet modules.
GPrep requires selective functionality depending on the site where it is in use, so
there are administrative privileges for configuring options during software
installation and setup.

GPrep Administrator ‐ is the local expert on GPrep. The Administrator is
familiar with the entire functionality of GPrep. The Administrator knows
how to configure all internal files, and how to grant certain permissions.
The Administrator knows how to clean all files of bad records and
supersedes. How to archive all files and e‐mail them to the appropriate
database administrator or RIMS analyst and how to train the day to day users
of GPrep. This person has the daily task of maintaining GPrep and its files.
•
GPrep User ‐ needs to know the fundamentals of GPrep. They need to know
how to log in, how to marry a meter with a module, and how to inspect a
module to ensure that it is properly programmed, and what to do if it is not.
Roles
PROCEDURES FOR GPREP ADMINISTRATOR
Verify your tools. GPrep does not operate without all of the tools listed in the
Required Tools section.
Unzip GPrep files to your PC or laptop.
Before copying files go to “View” on the menu bar of your PC, select “Folder
Options”. Under a section titled “Advanced Settings” there is a folder called
“Hidden files”, under that folder choose “show all files”, then click on the OK
button.
Customize GPrep.
The GPrep installation folder contains a file named GPREP.INI. This file
defines all configuration parameters in its [Control] section and
maintains settings from the last GPrep run in its [Default] section.
•
If this is a new installation, GPREP.INI must be copied to the GPrep
installation directory.
`ÉääåÉí=d~ë=jçÇìäÉ=~åÇ=jÉíÉê=fåëí~ää~íáçå=dìáÇÉ
VJP
d~ë=jÉíÉê=mêÉé~ê~íáçå=mêçÖê~ã=EdmêÉéF
•
If this is an upgrade, then you can use the existing GPREP.INI file to
modify any configuration parameters as necessary.
Edit the GPREP.INI file using Notepad or any other ASCII file editor.
Follow the instructions in that file to specify the required pattern for
Meter IDs, file(s) for logging operations, menu selections that are
available to the operator and the maximum memory used to track
previous log file associations.
If you run GPrep in different modes and/or it requires different configuration settings at the
same operator station, then install multiple copies of GPrep in different directories.
Following is an example of a GPREP.INI file.
; The Default section remembers GPrep settings from the last run. These
should
; not be changed manually.

Save your updates to the GPrep.ini file. GPrep is ready to use.
DATA TRANSFER
A local RIMS analyst performs this process. The RIMS Analyst uploads MRB and
Program files to the server via FTP.
Server Side Process
The person using GPrep, or the local administrator, posts the program log and
MRB files to Cellnetʹs FTP Server. You can use any SFTP Tool to post files from
gas and water processes. The GPREP.ini file determines the name and path of the
files generated in the local machine. Each Utility shop location can post multiple
files, as long as each file is uniquely identified . The local site can use any logic to
name these files, preferably to include date and time.
Once these files are posted, the DES server validates file format and cleanup
activities by eliminating duplicate entries and storing the program logs and MRB
data in staging tables . The server emails subscribers from source location . RIMS
CRON runs nightly, processing meters and updating the latest associations to
OCDB.

•
Inspect: Verifies that the programmed LAN Address has the same value as
the Power LAN Address label. In addition, “Inspect” permits validating the
other pre‐configured operational parameters. Discrepancies are noted
through message windows and the results of inspections are captured in
associated files.
The unique meter ID format for a given utility is defined in the “.ini” file. Any
discrepancy in the meter ID format is noted in a message window, which
prompts the operator to re-enter the meter ID prior to module programming. The
association record of meter ID, module LAN Address, date, operator’s name, and
result of operation is captured in the file “programlog.txt”.
•
Program New: provides the capability to program a new meter for a specified
rollover point and a meter constant for a specific utility meter ID format.
•
Re‐Program Old: provides the capability to program a meter with a non‐zero
index. This option was designed for utility meter shops to reprogram meter‐
modules pulled from the field or program a non‐zero index read. All other
features for this option are similar to the Program New mode. The
“programlog.txt” file also includes the index read entered during the
programming step as the field “opening read”.
•
MRB: captures the disassociation record for meters returned from the field.
This option is mainly designed for meter shop use during the O&M phase.
The following screens show how the operator has the option of choosing inspect,
program new, and index read when ResGas is chosen as the Meter Type.

MODULE INSPECTION
This feature is most commonly used when receiving meters from the factory with
Cellnet modules already installed (OEM Meters) or when receiving Cellnet
modules from Cellnet’s manufacturer. Different utilities use different sampling
procedures. Cellnet recommends that the meter shop verify a percentage of
inbound modules to ensure that the LAN Address that is programmed into the
module matches the LAN Address on the outside of the module housing. The
modules can also be inspected to verify that the correct Meter ID format was
used, that the rollover point is correct, and that the meter constant is correct.
Different modes of operation for ResGas modules are provided in detail. All other meter/
module types follows the identical functionality and operations, except as noted for Water
CPR.
Select Inspect from the Mode drop down window in the main menu. The
following screen displays.
Figure 9.8 GPrep “Inspect Mode” screen
There are two distinct sections on the screen. The top section is the LAN Address
field where the module power LAN label is either scanned or typed.

GPrep does not allow the operator to continue with this function.
If the current parameters do not match the predetermined values, a warning message
displays. (This is normal for new modules because a module coming from the
manufacturer is programmed with test parameters).
Module PCB ID (board ID) is populated during manufacturing. Upon verification of module
inspection, this value is saved in combination with the module Power LAN Address in the
Inspect file along with date, operator’s name and location of inspection.

Figure 9.10 “Inspect Mode” With Power LAN Scanned In
GPrep compares the Module ID entered in this field with the LAN Address
programmed into the module. If the populated field matches the programmed
value, a message displays “address verified”. If the entered value does not match
the programmed value a dialog box displays, stating the “LAN Address does not
match the programmed value” and instructs the operator to reenter the power
LAN label value, due to a misinterpretation or mis‐entered value. GPrep instructs
the operator to route the module to MRB for further disposition if the entered
values do not match again.
If the result of the inspection is verified, a record in the “inspect file” is created showing
that the module Inspection is successful. It also captures the PCB ID of the module in the
same record.
If the power LAN value does not match the programmed value, a record is also
generated in the “inspect file” showing the inspection has failed. Modules that fail
inspection must be segregated and routed to MRB.

MODULE PROGRAMMING
There are two modes for programming the modules. Program New is used when
a module is installed on a new meter with an index that reads zero, and Re‐
program old is used for programming a module that is being installed on a meter
that has an index with a value other than zero. This value is programmed into the
module to log in the starting read for a meter to be installed.
(An example of this is a periodic meter check in which a meter is taken from a
residence, inspected and then re‐deployed again into another residence).
Program New
Select Program new from the mode drop down window in the main menu.
The following screen displays.
There are two distinct sections in this screen as well. The top section contains the
following fields which can be modified by the user:
•
Meter ID field
If you are programming a Water CPR module, Device ID replaces Meter ID. A CPR module is
programmed with 10-digit left-justified(zero) Module ID as MeterID. Water CPR
programming also captures optional Encoder ID information.
•
LAN Address
•
Roll‐over point
•

The value entered in the dial field is programmed into the module as the starting meter
read at installation. Consumption is based on the initial read programmed into the module.
It is very important to be accurate on the dial index read. Note also that the dial field
requires the number of digits that correspond to the roll over point.
Example: If the roll over point is set at 10,000, then a four digit dial read would need to be
entered.
The index must have four dials if the roll over point of 10,000 is correct. Otherwise, the roll
over point must be changed accordingly. If the index read number contains more digits
than the corresponding rollover point, GPrep displays the following message prompting the
operator to reenter the index read and a blinking message in the main screen “dial
rejected” is also displayed.

MOST COMMONLY ASKED QUESTIONS
What does GPrep stand for?
Gas TOMM Preparation
What is GPrep used for?
GPrep is a tool that is used in the Cross Dock or meter shop to program gas or
water CPR modules without the use of a handheld. It is also used to
disassociate gas or water CPR modules from meters.
What is programmed into the module?
In the ʺProgram Newʺ and ʺRe‐Program Oldʺ modes, field operating
parameters are programmed into the module. Meter ID, Rollover Point, Dial
Read, and Meter Constant are the only parameters that can be changed by the
operator.
How does a meter constant work?
A meter constant is a multiplier that converts the pulses/turns of the module
into cubic feet. The reason for the meter constant to be .02 on a meter with a
2ft drive is that for every rotation of the drive dog there has passed 2 cubic ft
of gas. This is equivalent to 2% or .02 or 2/100ths of 1 point on the smallest of
the four dials, which measures hundreds of cubic feet. For every 50 rotations
of the 2‐ft dog dial 100 cubic feet of gas has passed. For every 50 rotations, the
1,000 dial has increased 1 point (100 cubic feet) and our module (if it happens
to transmit at that moment) sends out a packet with a count of 50. OCDB
multiplies the 50 by the meter constant .02 to get a read of 1, which we pass on
to the utility as a read of 1 for that meter. Therefore, if the meter constant were
falsely set to .01 the 50 rotations would be multiplied by .01 and would only
show that the meter used 50 cubic feet of gas.
Why donʹt you program the meter ID from the front of the meter into the
module?
The “Utility Billing ID” gets programmed into the meter; this is not usually
the same as the Meter ID.
What is a rollover point, how is it used, why is it important to make sure that
it is right?
The number at which the dials of a meter turn over and start at zero again.
For a four dial meter the numbers on the dials cannot go over 9999, therefore,
the rollover point is 10000, for 5 dial meters the rollover point is 100,000, etc. It
is important to program the correct rollover point into the module so that our
system read matches the dial plate.
What screen should I use in the sampling process?
There are several different types of sampling done by the meter shop. The
most common are sampling of Cellnet‐ready OEM meters, and sampling
modules from a Cellnet manufacturer, which are done using the “inspect”
mode.
Who is responsible for transferring the data files, how often, who writes the
scripts to pick up the data from the server?
The local database analyst is usually responsible for transferring the data
from GPrep to RIMS. He/she should do this daily (as long as there is data to
transfer). Someone in the database group writes the script to automatically
pick up this data daily.

How soon does the data get updated in each system after a module is
programmed?
A CRON job runs nightly that picks up the data that is put on the Cellnet
server and transfers it to RIMS. At a minimum there is a one day delay.
10 Why shouldn’t I take GPrep to the field?
Data management becomes difficult when the PC that GPrep is being used on
is not at a fixed location. The data that is captured by GPrep is time sensitive,
customer account information and should be copied and transferred daily.
The equipment that is used to operate GPrep is not made to be used outdoors.
If GPrep is taken to the field, it is vital that the data be transferred as soon as
possible upon return.
11 What data is captured by GPrep?
There is currently no screen that captures both the closing and opening reads
on a module (as needed for index changes). MRB mode should be used to
disassociate the module from the meter and capture the closing read.
Program‐old should then be used to re‐program the module with the new
index read.
12 What are some troubleshooting steps if GPrep is not working?
–
If you are using the shooter box, check the AC power, module plugged in,
shooter box turned on, correct DB9 to DB9 (RS232) cable (Non‐Null
Modem), correct COM port, ensuring that you are using the correct meter
type and mode, ex. ResGas v. commercial.
–
If you are using USB one way programming cable, refer to the 1‐Way
Module Programming Cable PC/Laptop Getting Started Guide.
13 What are the benefits of using re‐program old all of the time as opposed to
program new?
While some programs do this, there are no real benefits. It is a little easier to
prepare the programlog to send, but involves extra work for the end user.
14 What does it mean when a file is superseded?
Someone made a mistake and had to re‐enter a meter ID or LAN Address.
15 Who is responsible for cleaning these files (removing supersedes, converting
into an Excel spreadsheet, etc.)?
Typically someone designated by the utility performs this task before sending
these files to the database analyst.
16 Who should I contact if there is a problem?
First you should contact a local database analyst. Then try Cellnet Customer
Support at customersupport@cellnet.com.
17 When using different screens, why does the phrase “parameter reject” flash
yellow when I plug in a module that has just come from the manufacturer?
When modules are being made there are test parameters programmed in that
allow the manufacturer to make the module transmit more frequently than
every 15 minutes, and allows other tests to be run on them for quality
reasons. GPrep (or a handheld) replaces these test parameters with field
parameters.
