Installing and pairing the wUIU to a wireless extender (WEX)
In some installations, it may be necessary to increase the signal between the wUIU and the meter.
This is achieved by installing a Wireless Extender (WEX) between the meter and the wUIU, to ensure
consistent communication between the devices.
It is recommended that the distance between the WEX and the meter should not exceed 20 metres.
The WEX can be mounted on an exterior wall or light pole; and the device is powered via the mains
source (220-240V).
Once connected, the WEX can increase the signal to the wUIU to some 200 metres line of sight.
Following installation, it is necessary to pair the WEX:
Previously unpaired wUIU
A previously unpaired wUIU will show the following
display, once powered.
Enter the serial number of the WEX. As you enter the
digits, the display will scroll to the left.
When all 11 digits of the WEX serial number have been
entered, you will again see the following display.
Enter the 11 digit meter serial number. As you enter the
digits, the display will scroll to the left. When all digits have
been entered, the WEX starts communications.
If the pairing with the WEX is successful, the following will
be displayed.
If the pairing with the WEX is unsuccessful, the following
will be displayed. Check and confirm the WEX serial
number.
