The H8126-CB Energy Meter Communication Board is an optional field-installable
board for the H8163 Energy Meter, providing N2 communications capability. The
H8126-CB also enables the energy meter to provide true kW & kVAR demand
information.
The easy-to-install H8126-CB provides a simple, cost-effective way to network the
H8163 Energy Meter on the N2 bus.

INSTALLATION GUIDE
CAUTION! Danger of
explosion if battery is
incorrectly replaced.
Replace only with the
same or equivalent type
recommended by the
manufacturer. Dispose of
used batteries according
to the manufacturer’s
instructions.
RS-485 LED (TX):1. Red LED; blinks to indicate that the H8126-CB is transmitting
data to the master.
RS-485 LED (RX):2. Red LED; blinks to indicate that the H8126-CB is receiving data
from the master.
LED from Main Board (RX):3. Green LED; blinks to indicate that the H8126-CB is
receiving data from the main board.
LED from Main Board (TX):4. Green LED; blinks to indicate that the H8126-CB is
transmitting data to the main board.
“ALIVE” LED:5. Green LED; should blink once per second to indicate normal
operation of the H8126-CB.
N2 Network Address DIP Switches:6. Use these DIP switches to set the network
address for the H8126-CB. See the Settings table on page 3 for more information.
Connection to Energy Meter: Install the H8126-CB in the energy meter by
7.
inserting this connector into the connection slot at the top of the energy meter.
Communication DIP Switches:8. N2 factory default
RS-485 Communication Terminals: 9. Insert the RS-485 connector into these
terminals. See Wiring Diagrams on page 4 for instructions on wiring the connector
for 2-wire or 4-wire communications.
End of Demand Subinterval Terminal:10. Use this terminal as the input
connector for “end of demand interval” signal from the utility or other source. An
interposing isolated relay should be used as the dry contact for this
terminal, as pictured below. Do not apply voltage to this connection.

INSTALLATION GUIDE
InstallatIon
This section describes the communications settings you must make to the H8126-CB.
When daisy-chaining N2 devices, follow these guidelines:
Connect up to 63 H8126-CB devices on a single daisy chain. •
Each H8126-CB device on the daisy chain must have a unique address. •
Before connecting the H8126-CB to the RS-485 communication wires,
set the address according to directions on this page.
For RS-485 cables, use shielded, twisted-pair wire (Belden Cable 1120A or •
equivalent).
Terminate the last device on the daisy chain. If the H8126-CB is the last •
device in a daisy chain, terminate it to ensure reliable communication per
the RS-485 standard (120Ω nominal impedence).
Selecting The Network Address – DIP Switches
Use the Network Address DIP switches to selec t the network address. Each H8126-CB
on a daisy chain must have a unique network address (from 1 to 63). Devices with the
same address will be unable to communicate.
Always set the address before you install the H8126-CB in the energy meter and
before you connect the energy meter to the daisy chain.
Each of the six DIP switches has a unique address value. The N2 Addressing section on
page 6 lists DIP switch positions for specific addresses.

Wiring the Connector
Remove the 5-pin connector from the RS-485 communication terminals of the 1.
H8126-CB.
Wire the communications connector as shown on page 4 (2-wire communication).2.
Use a small, flat-blade screwdriver to tighten the connector screws.3.
Replace the connector on the RS-485 communication terminals of the H8126-CB.4.
If the H8126-CB is the last device in a daisy chain, terminate it to ensure reliable 5.
communication per the RS-485 standard (120Ω nominal impedence).
