To Program the OpenWay Gas Module
1. Make sure the 2.4GZ OpenWay Gas Module is within 10 feet of the programming
device.
2. Verify that the programming software is running.
3. Verify that red LED on ZigBee dongle is on.
4. Hold the magnet under the 2.4GZ OpenWay Gas Module for 5 seconds and then
remove it. You will see three red blinks from the LED. This signifies that the 2.4GZ
OpenWay Gas Module is searching for a programming device. Within a few seconds
the red LED will blink five more times. The programming device will indicate
programming success or failure.
a) If five red LED blinks are not seen on the 2.4GZ OpenWay Gas Module, hold the
magnet under 2.4GZ OpenWay Gas Module for 5 seconds.
Chapter 2 American Meter Installation
18 2.4GZ OpenWay Gas Module Installation Guide
b) If 5 red LED blinks are seen on the 2.4GZ OpenWay Gas Module, but the
programming device indicates that programming failed, verify the following (1)
2.4GZ is within 10 foot range of programming device and (2) programming
software is using correct security key. Repeat holding magnet under 2.4GZ for 5
seconds.
When the 2.4GZ OpenWay Gas Module has been programmed to normal mode, it is ready
to commission to an OpenWay CENTRON meter. If an OpenWay CENTRON meter is
within range of the 2.4GZ OpenWay Gas Module, the red LED on the 2.4GZ OpenWay Gas
Module will blink three times, indicating that it is looking for all available OpenWay
CENTRON meters.
After choosing the OpenWay CENTRON meter with the best signal, the 2.4GZ OpenWay
Gas Module will blink five times to indicate successful commissioning to the meter. The
timing for this could be as quick as one second after being programmed. If within two
minutes of successful programming, the five blinks are not seen, make note of the
installation for further investigation.
NOTE Itron will be moving to this programming solution in 2008
1. Using the FC200 and Belt Clip radio, program the reading of the index that was on the
meter into the OpenWay Gas Module assembly.
During programming, the OpenWay Gas 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 OpenWay Gas Module assembly can be read
to the nearest cubic foot.
2. Slowly turn the OpenWay Gas Module drive wriggler two turns in the direction
indicated on the index drive rate. This lets you verify the module is counting properly
after assembly.
IMPORTANT Do not turn the drive wriggler faster than one turn per second.

2.4GZ OpenWay Gas Module Installation Guide 21
• For Two-Foot Meters: Align the OpenWay Gas Module assembly wriggler
with the meter drive slot (as shown below). It is acceptable for the pin on the
module wriggler to be installed inside or outside of the meter drive slot. For
ease of assembly, Itron recommends that the pin on the OpenWay Gas Module
wriggler be installed outside of the meter drive slot.
3. Gently place the OpenWay Gas Module assembly on the meter. Align the four screw
holes on the module assembly with the holes on the meter.
4. Turn each screw 1/4 to 1/2 turn after it contacts the cover. Use the 1/4 - 20 x 5/8-inch
