TDC-0832-001 2.4ZR OpenWay® Range Extender Installation Guide 17
Proprietary and Confidential
If communication stops or you cannot establish communication between the range extender and the
CENTRON meter or the gas module, try one or all of the following solutions.
Use a handheld computer loaded with Endpoint-Link or FDM software to check the configuration settings
of the gas module and the range extender. These settings should match.
Repeat the steps in Configuring the 2.4ZR Range Extender on page 7.
Repeat the steps in Linking to a CENTRON Meter on page 11 and Linking to a 2.4GZ OpenWay Gas
Module on page 12.
Important The order you perform the magnet swipes when setting up RF paths is critical. The path
between the range extender and the electric meter must be established first. The gas module must have a
magnet swipe during the install window, to establish its connection to the range extender.
If communication continues to fail, contact Itron to replace the 2.4ZR OpenWay Range Extender.
Magnet Swipe Outcomes
A magnet swipe causes one of four possible outcomes:
1. If the range extender is swiped with the programming magnet while it is in Sleep mode and a handheld
computer is not present:
Both range extender LEDs blink three times to indicate the range extender is searching for a handheld
network.
If a handheld network is discovered, the range extender follows the CENTRON meter's join sequence.
If the range extender does not successfully join a CENTRON network, the range extender
enters Sleep mode.
If the range extender joins with a CENTRON meter but a 2.4GZ gas module does not join through the
range extender, the range extender enters Sleep mode.
2. If the range extender is swiped with the programming magnet while in Sleep mode and in the presence of
a handheld:
Both range extender LEDs blink three times to indicate the range extender is scanning for active
networks.
If a handheld network is found, the range extender attempts to join the network.
After the range extender joins the handheld network, both LEDs blink five times.
At the end of the range extender's Handheld mode, the range extender may be immediately placed into
Sleep mode by the handheld, or the range extender will enter the discover network process (join
CENTRON meter sequence) by default. If a network is not discovered, the range extender enters Sleep
mode. If the range extender does not successfully join a , the range extender enters Sleep mode. If the
range extender joins with a CENTRON meter but a 2.4GZ gas module does not join through the range
extender, the range extender enters Sleep mode.
