Getting Started

The 100G is Itron's latest high-powered gas encoder-receiver-transmitter (ERT) module.
ERTs are meter-installed devices that transmit meter data using radio communications. That information may be received by a reading device that is within transmission distance, meaning that multiple devices may receive data from a single endpoint. Itron's 100G ERT is a high-powered device with a wide transmission distance.
This installation guide shows you how to install the 100G ERT module on meters from a variety of manufacturers. To ensure you have a meter that is compatible with the 100G ERT module, please see the

Transmission Modes

Once installed, the 100G ERT module has two standard available transmission modes:
Meter Compatibility List on page 2.
Fixed Network Mode In this mode, a 100G ERT module transmits a high-powered
RF message every 60 seconds.
Mobile and HandHeld Mode In this mode, a 100G ERT module transmits a medium-powered RF message every 15 seconds.
An FCC license is not required to read 100G ERT modules.

2. Detach the index cover from the meter by removing the four screws holding it in
place.
3. Examine the index cover screws you just removed. Verify that they are 5/8-inch long
and are not corroded.
If the screws are 5/8-inch long, and are not corroded, keep them for later use.
If the screws are an incorrect length or are corroded, dispose of them properly.
Use 1/4 - 20 x 5/8-inch screws as described in
Replacement Screws on page 6
instead.
TIP You can use the index cover you just removed as a temporary storage location for screws.
4. Unscrew one index mounting screw completely.
Hold one hand beneath the index to catch the screw when it falls out of the index assembly. If it does not fall out by itself, be sure to remove it.
5. Unscrew the other index mounting screw.
100G Installation Guide 7
Chapter 2 American Meter Installation
While removing this screw, pull the index away from the meter to keep its backplate (1) against the back of the screwhead (2). This prevents the screw from falling out prematurely.
6. Remove the screw from the index once it is completely free of its hole.
7. Set the index aside for the moment. Place it where it will not be damaged; get filled
with dirt, rain, or snow; or fall to the ground or floor. The index will be used later in this procedure.

To Program the ERT Module

1. Using the FC200/SR, program the reading of the index that was on the meter into the
ERT module assembly. Be sure to hold the FC200/SR unit by the battery pack and within a few inches of the ERT during programming and reading; this will ensure proper communication between unit and the ERT.
During programming, the 100G ERT module is programmed to the
feet
; the last two digits (the tens and units) are programmed as zeros (0). Once programming is complete, however, the ERT module assembly can be read to the nearest cubic foot.
2. Slowly turn the ERT module drive wriggler two turns in the direction indicated on the
index drive rate. This lets you verify the ERT module is counting properly after assembly.

4. Attach the right-hand mounting screw to the index and meter, just far enough to hold
the index in place. Use one 6 - 32 x 5/8-inch screw for this step (you can use an original mounting screw if it was the correct size and not corroded; otherwise, use the correct size
Replacement Screw see "Replacement Screws" on page 19).
5. Install and tighten the left-hand index mounting screw.
6. Tighten the right-hand index mounting screw completely.

7. Slide the ERT cover over the index and backplate.
8. Verify that the cover is installed correctly; the cover's clear window should be over
the backplate label.
Once combined, the ERT backplate, meter index, and ERT cover create an "ERT Module Assembly."
Next, program the ERT module.

Program the ERT

Once the ERT module has been assembled, the ERT must be programmed using the FC200/SR with EndPoint-Link software. See the
(TDC-tbd-xxx
) for more information.
EndPoint-Link ERT Programming Guide
IMPORTANT You must perform the following programming procedure for the ERT module to function properly.
When programming the ERT module, you must take note of the drive rate shown on the index of Sensus meters. Sensus meters have a 2-foot drive rate, as indicated in the example below (1).

To Program the ERT Module

1. Using the FC200/SR, program the reading of the index that was on the meter into the
ERT module assembly. Be sure to hold the FC200/SR unit by the battery pack and within a few inches of the ERT during programming and reading; this will ensure proper communication between unit and the ERT.

During programming, the 100G ERT module is programmed to the nearest 100 cubic feet
; the last two digits (the tens and units) are programmed as zeros (0). Once programming is complete, however, the ERT module assembly can be read to the nearest cubic foot.
2. Slowly turn the ERT module drive wriggler two turns in the direction indicated on the
index drive rate. This lets you verify the ERT module is counting properly after assembly.
IMPORTANT Do not turn the drive wriggler faster than one turn per second.
3. Read the ERT module assembly using the FC200SR. Consult the
Programming Guide
(TDC-tbd-tbd) or other applicable instructions for details on how
EndPoint-Link ERT
to read an ERT.
If this reading is higher than the one you programmed in step 1 above, the ERT
module assembly is counting correctly.
If the ERT module assembly reading is
in step 1, replace the ERT module with a new one.
not higher than what was programmed

Attach the ERT to the Meter

After the ERT has been programmed and is reading correctly, it must be attached to the meter. Follow the steps below to do this.

Chapter 3 Sensus Meter Installation

To Attach the ERT to the Meter

1. Gently place the ERT module assembly against the front of the meter as shown. Make
sure all four mounting screw holes in the ERT module assembly line up with the corresponding holes on the meter.
2. Insert the top-right cover mounting screw. Tighten the screw just enough to hold the
ERT module assembly in place. Use the 10 - 24 5/8-inch screws for this and the following step (you can use the original mounting screws if they were the correct size and not corroded; otherwise, use the correct size as described in on page
19).
