Ethernet
Connects the CCU/Repeater to the Ethernet backhaul. Also used to connect the CCU/Repeater to a
router for initial collector setup. Mating weatherproof cables are available from Itron. These cables are
sealed industrial ethernet circular IP67 connectors (CONEC)
Note A waterproof cap seals the Ethernet port from the elements in the field. Be sure to securely
attach the cap once the collector is installed.
8
Ground lug
The ground lug is provided on both the CCU and the Repeater and should be attached to earth ground
if no ground is available in the three conductor power cable or when using a photocell adapter. This
ground helps protect the internal circuitry from high voltage transient events. The ground lug accepts
AWG minimum wire size 14, and maximum wire size 4.

Status indicator
This indicator displays the current operational status of the CCU/Repeater. See Status Indicator on
page 61 for more information.

Removal of this door allows access to the replaceable battery pack.
External GPS/WAN Antenna System
The external antenna CCU/Repeater configuration uses a GPS/WAN antenna kit that is
connected to the CCU/Repeater by one or two separate pieces of coaxial cable. Cables are
not included in the kit.
• The WAN antenna is only connected in CCU installations that use a wide area
network backhaul system.
• The GPS antenna is used in all deployments of this system.
The antennas must be installed in a location that allows reception of GPS and WAN
signals.
Itron recommends using a handheld GPS unit to verify that your GPS antenna mounting
location can receive a signal from at least three satellites.
For more information, see GPS and WAN Coverage on page 8.
Caution The external GPS antenna must be oriented vertically when installed, and it
must have an unobstructed view of the sky to properly receive a GPS signal.
