quick install
1. Turn off all power to the energy meter and the equipment in which it is installed.
2. Discharge static.
3. Slide the H8186-CB into the channels on either side of the energy meter until the
male connection on the meter clicks into place.
4. Insert the communication terminal onto the RS-485 communication terminals.
5. If the demand subinterval feature is used, wire it into the end of the demand
subinterval terminal.
6. Replace the voltage terminal into the energy meter.
H81xxCB Series interfaces are sold as open devices.
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.

H8186-CB Energy Meter Communication Board is an optional field-installable board
for the H8163 Energy Meter that provides a simple, cost-effective way to network the
H8163 Energy Meter to an existing control/data acquisition systems via BACnet-
MS/TP communications capability. The H8186-CB is designed as a plug-and-play
accessory for the H8163 energy meter.
The H8186-CB features field selectable parity (odd/even/none). It works with 2-wire
and 4-wire systems, and it has a field selectable baud rate (9600, 19200, 38400).

Communication DIP Switches:
Use these DIP switches to set the H8186-CB
wiring type, baud rate, and parity.
9.
RS-485 Communication Terminals:
Insert the RS-485 connector into these
terminals. See the Wiring Diagram section of this guide for instructions on wiring
the connector for 2-wire or 4-wire communications.
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 manufacturers instructions.
This section describes the communications settings you must make to the H8186-CB.
When daisy-chaining devices, follow these guidelines:
You can connect up to 63 H8186-CB devices on a single daisy chain.

Each H8186-CB device on the daisy chain must have a unique address.

Before connecting the H8186-CB to the RS-485 communication wires,
set the address according to directions in Selecting the Network Address
DIP Switches on this page. If you assign the same address to two devices,
neither device will communicate.
Set the wiring type, baud rate, and parity according to directions in

Selecting Wiring Type, Baud Rate, and ParityCommunication DIP
Switches on this page. The settings for each H8186-CB must match the
other devices on its daisy chain.
For RS-485 cables, use shielded, twisted-pair wire (Belden Cable 1120A or

equivalent).
Terminate the last device on the daisy chain. If the H8186-CB is the last

device, per the RS-485 standard (120 ohm nominal impedence).
Selecting The Network Address DIP Switches
Use the Network Address DIP switches to select the network address. Each H8186-CB
on a daisy chain must have a unique network address (from 063). Devices with the
same address will be unable to communicate.
Always set the address before you install the H8186-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, page 8 lists DIP switch posi-
tions for specific addresses.

Selecting Wiring Type, Baud Rate, and Parity Communication DIP Switches
Use the communication DIP switches (pictured below) to set the H8186-CB wiring
type, baud rate, and parity.
The figures below list the baud rate and parity switch settings and the locations of
the switches that control wiring, baud rate, and parity.

Daisy Chain Maximum Distances
The maximum number of devices capable of being supported on a single daisy chain
is determined based on the combination of baud rate, the length of the daisy chain,
and the types of RS-485 devices (2-wire/4-wire) on the daisy chain. The RS-485
interface will support daisy chains that fall within the specifications shown below.

Wiring the Connector
Remove the connector from the RS-485 communication terminals of the H8186-CB
(see Wiring Diagram section). To wire RS-485 communications, follow these steps:
1. Wire the communications connector for either 2-wire communication or 4-wire
communication (see Wiring Diagram section).
NOTE: The Wire Type setting in the communication DIP switch must match this
wiring type (see settings diagram, previous section, for communication DIP switch
settings).
2. Use a small, flat-blade screwdriver to tighten the connector screws.
3. Replace the connector on the RS-485 communication terminals of the H8186-CB.
4. If the H8186-CB is the last device on the daisy chain, terminate it, to ensure
reliable communication per the RS-485 standard (120 nominal impedence).
