INSTALLATIoN GUIDe

oPeration

H8186-CB energy meter communication board is an optional eld-installable plugand-play accessory board for the H81xx energy meter that allows networking the H81xx to an existing BACnet MS/TP control/data acquisition system. It features eld selectable baud rate (9600, 19200, 38400).

configuration

This section describes the communications settings you must make to the H8186-CB. When daisy-chaining devices, follow these guidelines:

• 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 baud rate according to directions in “Selecting Baud Rate — Communication DIP Switches.” 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).

• If the H8186-CB is the last device, terminate it per the RS-485 standard (120 Ω 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 0 to 63). 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 6 lists DIP switch positions for specic addresses.

Network Address DIP Switch Values

Switch Value

1 1

2 2

3 4

4 8

5 16

6 32

In this example, the network address for the device is 40. Switch 4 and 6 oer the only combination of values that total 40.

This gure illustrates how to set the switches. Up is ON; down is OFF.

Selecting Baud Rate – Communication DIP Switches

Use the communication DIP switches (pictured below) to set the H8186-CB baud rate.

The gures below list the baud rate switch settings and the location of these switches.

them in the OFF position.

This example illustrates the default switch

settings for a 2-wire device that uses 9600 baud rate.

Parity function is not applicable to this model;

leave these switches in the OFF position.

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 on the daisy chain. The RS-485 interface will support daisy chains that fall within the specications shown below.

2-Wire Daisy Chain Maximum Distances

Baud Rate Maximum Distances

1-8 Devices 9-16 Devices

9600 10000 ft. (3048 m) 4000 ft. (1219 m)

19200 5000 ft. (1,524 m) 2500 ft. (762 m)

38400 2500 ft. (762 m) 1200 ft. (380 m)

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 2-wire communication (see Wiring Diagram section). The Wire Type setting in the communication DIP switch must match this wiring type (set Switch 2 to the ON position; see Selecting Baud Rate section).

2. Use a small, at-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 Ω nominal impedence).
