To comply with FCC RF exposure compliance requirements, the antenna used for this
transmitter must be installed to provide a separation distance of at least 20 cm from all persons
and must not be co-located or operate in conjunction with any other antenna or transmitter.”
As such, the radio component of this device is intended only for OEM integrators under the
following two conditions:
Warning
1. The antenna must be installed such that 20 cm is maintained between the antenna and
2. The transmitter module may not be co-located with any other transmitter or antenna.
As long as the two conditions above are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end product for any additional
compliance requirements required with this module installed (e.g., digital device emissions, PC
peripheral requirements).
In the event that these conditions cannot be met (for example, co-location with another
transmitter), then the FCC authorization is no longer considered valid and the FCC ID cannot
be used on the final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be
installed such that 20 cm may be maintained between the antenna and users (for example
access points, routers, wireless ASDL modems, certain laptop configurations, and similar
equipment). The final end product must be labeled in a visible area with the following:
“FCC ID: F9X2400B”.

ECR-2400 Node Hardware
2.1 Overview
The ECR-2400 node is an under-the-glass board designed for installation in an
ECR-2400 meter. The node plugs into the meter and provides an easy and
reliable way to enable meters to automatically form a wireless mesh network.
This section describes the procedures to integrate an ECR-2400 node with a
ECR-2400 meter.

Figure 2.2 below is a simple diagram of an ECR-2400 node. The primary
components of the node are:
• the meter interface connector - connects the node to the meter
• the AC power connection - supplies power to the node
• the node’s serial number - the node’s unique identifier
• LEDs - red and green lights displaying node’s operating status

Each ECR-2400 node is uniquely identified with a serial number . This number is
displayed on the label and is contained on the bar code. In addition, the number
is also embedded in the node’s software. This serial number is the number
displayed on the Field Tool and Network Manager to identify the node.
During installation, it is important to note the Eka Serial Number and the serial
number of the meter in which it is installed in the event that the node and/or
meter require troubleshooting.

begin operation.
2.2.1 What the Blinking Lights Mean
2.2.1.1 The Green LED
During the initial boot up the green LED may blink unevenly. However after 10
seconds the green LED should begin blinking at a steady r ate of 1/2 second on
and 1/2 second off. This is considered the node’s “heartbeat.” If the green light
fails to come on, is a solid green, or flashes at any other rate, the node has
malfunctioned and the node must be replaced.
2.2.1.2 The Red LED
During the initial boot up the red LED may blink unevenly. During system
operation the red LED will be a solid red whenever it is communicating with any
other Eka node. If the red light flashes continuously, the node has malfunctioned
and the node must be replaced.

be used on the final product. In these circumstances, the OEM integrator will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be
installed such that 20 cm may be maintained between the antenna and users (for example
access points, routers, wireless ASDL modems, certain laptop configurations, and similar
equipment). The final end product must be labeled in a visible area with the following:
“FCC ID: F9X2400B”.
The radio component is an integral part of the Eka module and cannot be removed.

3.2.1 What the Blinking Lights Mean
3.2.1.1 The Green LED
During the initial boot up the green LED may blink unevenly. However after 10
seconds the green LED should begin blinking at a steady r ate of 1/2 second on
and 1/2 second off. This is considered the node’s “heartbeat.” If the green light
fails to come on, is a solid green, or flashes at any other rate, the node has
malfunctioned and the node must be replaced.
3.2.1.2 The Red LED
During the initial boot up the red LED may blink unevenly. During system
operation the red LED will be a solid red whenever it is communicating with any
other Eka node. If the red light flashes continuously, the node has malfunctioned
