i-Vu Open Link 1
What is the i-Vu Open Link?
The i-Vu Open Link is a BACnet device router that acts as a gateway between the BACnet IP network and a
BACnet MS/TP network. The i-Vu Open Link increases the capacity of an Open system, allowing individual
MS/TP networks (with up to 60 Open controllers each) to be connected via a common BACnet/IP backbone.
The i-Vu Open Link can also integrate third-party equipment, supporting BACnet MS/TP, BACnet/IP, Modbus
RTU, Modbus/IP, and LON FT-10 protocols. The i-Vu Open Link has one EIA-485 port for connecting to the
Open or third-party MS/TP bus, and one jumper-configurable EIA-232/EIA-485 port for connecting to a
Modbus or LonWorks network. It also has one 10/100 Base-T Ethernet port for connecting to the building
LAN and integrating to third-party IP control networks.

To wire for power
1 Make sure the i-Vu Open Link’s power switch is in the OFF position to prevent it from powering up before
you can verify the correct voltage.
2 Remove power from the power supply.
3 Pull the screw terminal connector from the controller's power terminals labeled 24V ac/dc and Ground.
4 Connect the transformer wires to the screw terminal connector.
5 Apply power to the power supply.
6 Measure the voltage at the i-Vu Open Link’s power input terminals to verify that the voltage is within the
operating range of 21.6 – 26.4 Vac or 23.4 - 28.6 Vdc.
7 Insert the screw terminal connector into the i-Vu Open Link's power terminals.
8 Turn on the i-Vu Open Link's power.
9 Verify that the Run LED (a dot in the lower right corner of the Module Status LED) begins blinking. The
Module Status LED will display 8 for about 5 seconds and then reverts to 0, until Open controllers have

NOTES
•If you cannot determine the media type or connections of the third-party device, contact your third-party
representative.
•Use the same polarity throughout the network segment.
•Repeaters are required for more than 31 devices. See your third-party device manufacturer's
recommendations.
•To reduce communication and data errors, terminate each end of an EIA-485 network with a resistor
whose value equals the network's characteristic impedance. Some third-party manufacturers provide a
built-in resistor that you enable or disable with a jumper. Make sure that only devices at the end of a
network have termination enabled.
EXAMPLE If an EIA-485 2-wire network's characteristic impedance is 120 Ohms, terminate one pair by
placing a 120 Ohm resistor across the Net+ and NET-connectors of the i-Vu Open Link. Terminate the
other pair by placing a 120 Ohm resistor across the + and -connectors of the furthest third-party
controller.
•A solid receive light on the i-Vu Open Link indicates a wiring or polarity problem.
Addressing the i-Vu Open Link
i-Vu Open Control hardware, when used in conjunction with i-Vu Open routers (i-Vu Open Link and i-Vu Open
Router), has a convenient feature of automatic addressing. To address the i-Vu Open Link for third-party
integration, using i-Vu/Field Assistant, go to Driver Properties > Protocols > Properties tab. Refer to the
appropriate protocol Integration Guide for further details.
The i-Vu Open Link needs two addresses, one for the Open network and one for the IP Network.

Notes
A router address Open network You set the i-Vu Open Link address on the
controller's rotary switches. (1 - 99)
NOTES
•The i-Vu Open Link address is also used to
auto-generate the BACnet device
instance/name for the router and the
MS/TP network number for the connected
Open network. See Configuring BACnet
device instance and network number.
An IP address IP Network Use the IP Address DIP switch to choose one of
the following:
•Use DHCP to obtain an IP address
•Assign a
custom
The default IP settings are:
IP address (default)
•192.168.168x, where x = router address
•subnet mask = 255.255.255.0
•default gateway = 192.168.168.254
To set the i-Vu Open Link address on the Open network
CAUTION The router address must be unique on the IP and Open network.
1 If wired for power, turn off the controller's power. The controller reads the address each time you turn it
on.
2 Use the rotary switches to set the address. Set the Tens (10's) switch to the tens digit of the address,
and set the Ones (1's) switch to the ones digit. Valid addresses are 1 - 99.
EXAMPLE If the controller’s address is 25, point the arrow on the Tens (10's) switch to 2 and the arrow
on the Ones (1's) switch to 5.

i-Vu Open Link 9
To choose an IP addressing scheme
Carefully plan your addressing scheme to avoid duplicating addresses.
•If there is a DHCP server on the network, and, if you have a single i-Vu Open Link or multiple i-Vu Open
Links that exist on the SAME subnet, use DHCP addressing. Skip to the section To obtain an IP address
using DHCP (page 9).
•If you have multiple i-Vu Open Links that reside on different subnets, you cannot use DHCP addressing.
Instead, give each i-Vu Open Link an assigned IP address. Skip to the section To assign a custom IP
address (page 9).
NOTE This network configuration also requires that you configure IP Broadcast Management Devices
(BBMDs. See To set up BACnet Broadcast Management Devices. (page 15)
By default, the i-Vu Open Link is set up for assigned IP addressing. The default IP address settings are as
follows:
•IP address = 192.168.168.x, where x = i-Vu Open Link address (rotary switch settings)
•Subnet Mask = 255.255.255.0
•Default Gateway = 192.168.168.254
To obtain an IP address using DHCP
1 Turn the i-Vu Open Link's power off.
2 Set the IP Addr DIP switch to OFF (DHCP).
3 Turn the i-Vu Open Link's power on. The DHCP server assigns an IP address to the i-Vu Open Link.
To assign a custom IP address
1 Obtain the IP address, subnet mask, and default gateway address for your router from the facility
network administrator.
2 Turn the i-Vu Open Link's power off.
3 Set the i-Vu Open Link's IP Addr DIP switch to ON. (Assigned)
4 Configure the i-Vu Open Link by setting the Router Config Mode DIP switch to (Console):
○ON if you use a terminal program, such as Hyperterminal
○OFF if you use Carrier software, such as BACview
NOTE The DIP switch on older models was labeled Hyperterminal.
5 Turn the i-Vu Open Link's power on.

Using Port S2
Prerequisite Computer must have a standard serial port.
1 Make sure that the Port S2 jumper is set for EIA-232.
2 Obtain a standard 9-pin serial cable. There are two different ways to connect the serial cable to Port S2:
○Connect an S2-DB9 converter (part# S2-DB9) into Port S2. Plug the 9-pin end of the serial cable
directly into the DB9 connector of the S2-DB9.
○Trim one end of the serial cable to expose the wires to be connected directly to Port S2 of the i-Vu
Open Link.
3 If you are using a trimmed cable, then terminate the TX, RX, and Ground wires of the 9-pin serial cable to
Port S2 on the i-Vu Open Link. See table below.
Serial Cable (9 pin)

TX (pin 3) RX (pin 2)
RX (pin 2) TX (pin 1)
Ground (pin 5) Ground (pin 5)
4 Follow steps 4 - 19 above to launch a terminal program and access the Router Configuration screen to
set the IP parameters.
5 Reset the Port S2 jumper to the EIA-485 position.
6 Cycle the i-Vu Open Link's power to accept the DIP switch settings.
Configuring BACnet device instance and network number
All BACnet Open controllers must have a unique device instance and name. These BACnet addresses are
automatically generated and usually do not require modification. However, sometimes you need to override
the automatic addressing assignments.
Autogenerated Addressing Scheme:
The i-Vu Open Link's rotary address setting determines the automatic BACnet addressing scheme for the
connected Open network.
Legend
16 = Carrier's BACnet Vendor ID
xx = Router's rotary address (router address)
yy = Open controller's rotary address (MS/TP MAC address)
For the router:
•BACnet Device Instance Number = 1600xx
•BACnet Device Instance Name = device1600xx

i-Vu Open Link 13
•BACnet IP Network Number = 1600
•BACnet MS/TP Network Number = 161xx
•Port S1 MS/TP MAC Address = 0 (fixed)
For the connected Open controllers:
•BACnet Device Instance Number = 161xxyy
•BACnet Device Instance Name = device161xxyy
•MS/TP MAC Address = yy
•BACnet MS/TP Network Number = 161xx (actually learned from the router, defaults to 16101 if no i-Vu
Open Link is operating)
If the BACnet automatic settings need to be changed, launch the Router Configuration utility using a terminal
program. See To assign a custom IP address (page 9) for instructions on connecting to and using a terminal
program.
To change the BACnet settings:
1 Enter the BACnet selection# from the menu. Type the new setting and click Enter. The new setting will
appear on the Router Configuration screen.
2 Cycle power to the router for the new settings to effect.
NOTE If the BACnet MS/TP network number of the router is assigned and not auto-generated, and the
Open controllers connected to that router are set such that their BACnet settings are auto-generated,
then the Open controller BACnet settings will be auto-generated based on the assigned MS/TP network
number in the Router:
Example A router's BACnet MS/TP network has been assigned to 200.
If the connected Open Controllers are using the auto-generate scheme, then their settings will be:
BACnet MS/TP Network Number = 200
BACnet Device Instance Number = 200xxyy
BACnet Device Instance Name = device200xxyy
MS/TP MAC Address = yy

the controller loses power during occupancy.
On a Time Synch signal, update the controller clock only if the
controller time differs from the signal time by more than this
value.
Time Synch Sensitivity
(seconds)
BACnet COV Throttling
Under normal circumstances, COV Throttling should be enabled to
prevent excessive network traffic if an object's COV Increment is
set too low. See EXCEPTION below.
Enable COV Throttling
When enabled, if an object generates excessive COV broadcasts
(5 updates in 3 seconds), the module driver automatically throttles
the broadcasts to 1 per second. Also, if the object's value updates
excessively for 30 seconds, an alarm is sent to i-Vu/Field Assistant
listing all objects that are updating excessively. A Return-to-normal
alarm is sent only after all objects have stopped updating
excessively.
EXCEPTION
In rare circumstances, such as process control, a
subscribing object may require COV updates more frequently than
once per second. For these situations, clear this checkbox, but
make sure that your network can support the increased traffic.
You also need to disable the
Excessive COV
alarms under the
driver's
Common Alarms
.

i-Vu Open Link 15
To set up BACnet Broadcast Management Devices (BBMDs)
If your system has multiple routers that reside on different IP subnets, you must set up one router on each IP
subnet as a BACnet/IP Broadcast Management Device (BBMD).
Every subnet with a router must have a BBMD configured in order for broadcasts from controllers on that
subnet to reach the rest of the routers on the network.
NOTE If the i-Vu appliance is on a separate subnet than the rest of the routers, the internal router must be
assigned an IP address and configured as a BBMD.
Use the BBMD Configuration Tool to:
•Define the Broadcast Distribution Table (BDT) in each BBMD
•Enable an i-Vu Open Control System to find routers that are on different subnets
•Allow controllers on one subnet to communicate with controllers on other subnets
•Enable i-Vu to see, upload, or configure controllers on different subnets
NOTE In this document, the term "router" refers to the i-Vu Open Router or the i-Vu Open Link.
1 Assign an IP address, subnet mask, and default gateway for each i-Vu Open Link on the IP network. See
Addressing the i-Vu Open Link (page
To set up BBMDs using the BBMD Configuration Tool
7).
2 Acquire the BBMD Configuration Tool from the Tech Tools DVD or from the Carrier Control Systems
Support Site http://www.hvacpartners.com/. This is a stand-alone executable file and no installation is
necessary.
3 Make a list of the IP addresses for each router that will function as a BBMD in your system.
In the above illustration, the i-Vu Open Link, address 172.18.1.2, must be configured as a BBMD for the
172.18 subnet, while the i-Vu Open Link, address 172.16.1.15, must be configured as a BBMD for the
172.16 subnet.

Installation
16 i-Vu Open Link
CAUTIONS
○Multiple BBMD's on an IP subnet disrupt BACnet communications. Define only one BBMD per
subnet.
○Unless explicitly modified, the UDP Port for BACnet/IP is 0xBAC0 (47808). Do not change this
parameter unless you made a change in the router.
4 In a text editor such as Notepad, create a list of the routers that will be BBMD's. List each IP address on
a separate line. (Maximum of 50 IP addresses per file)
5 Save the file to your folder of choice with a .bdt extension instead of .txt.
NOTE ".bdt" is a Broadcast Distribution Table file.
6 Open the BBMD Configuration Tool.
7 In the IP Address or Host Name field, type the IP address of the router that functions as the BBMD
(BACnet Broadcast Management Device) for its subnet.
8 To check if the router has an existing BBMD table, click Broadcast Distribution Table Read button.
9 If the Broadcast Distribution Table contains IP addresses that are not in your .bdt file, verify that they are
valid BBMD's and, if so, add them to your .bdt file.
NOTES
○The BDT's in each BBMD must be identical. Be sure to repeat this entire process whenever a BBMD
is added.
○If needed, disable the checkbox next to Show Broadcast to limit the amount of scrolling text that is
displayed.
10 Click the Broadcast Distribution Table Browse button and select the .bdt file that you made in step 4.
11 Verify that the appropriate IP address is still in the IP Address or Host Name field.
12 Click the Broadcast Distribution Table Write button.
13 Click Read again to verify that the new .bdt file was written to the router. See example below.
