To start the backup, select the PC Backup button.

A popup will appear letting you know the i-Vu server will stop while it backs up all the data. That includes trends, logs, alarms, equipment and view files as well as setpoints. The only thing not included in the i-Vu servers IP info.

Open Windows Firewall

Step 1: Open the Control Panel. Hold down the Windows key ( ) and press "X". Select "Control Panel" in the menu

Step 2: Open Windows Firewall Settings. In the Control Panel select "System and Security" ...

Step 3: Enable the Firewall. Ensure that both the private and public network firewalls are turned on.


In Windows 10, the Windows Firewall hasn’t changed very much since Vista. Overall, it’s pretty much the same. Inbound connections to programs are blocked unless they are on the allowed list. Outbound connections are not blocked if they do not match a rule. You also have a Public and Private network profile for the firewall and can control exactly which program can communicate on the private network as opposed to the Internet.

The easiest way to tell if the battery in an AOpen box has failed is that it does not recover from a restart or power cycle. Connecting a monitor to it in this state will yield a message stating “No keyboard found”.

NOTE: This should not be done on products under warranty. Replacing the battery will void the warranty. If the i-Vu box is still under warranty, request an RMA or contact your HAVC controls  contractor.


Battery replacement steps :

1. Completely disconnect all cables from the i-Vu box.
2. Remove the plastic lid by gently prying the lid from the side of the Aopen box using a small screwdriver. 3. Unscrew the four screws on top of the CD player.
4. Lift the metal cover straight up to remove the CD player.
5. Locate the CR2032 battery and note its polarity relative to its orientation and then replace the battery with a new one keeping the same polarity and orientation.
6. Replace the CD player, screws and cover.
7. Connect the keyboard, monitor and power.
8. Turn the unit on while tapping the Delete key on the keyboard. This should take you into the BIOS Configuration screen which contains a text menu with a blue background.
9. Using the key to confirm and to go back, configure the following settings: 
    a. Under Standard CMOS Features 
        i. Set the time. 
       ii. Set Halt On to: All, But Disk/Key 
    b. Under Advanced BIOS Features 

        i. Set First Boot Device to CDROM (or Removable, if it is a newer server with no Optical drive) 

        ii. Set Second Boot Device to Hard Disk 
c.Under Power Management Setup 

         i. Set AC PWR Auto Recovery to On 
10.Select Save & Exit Setup and hit again at the confirmation prompt.
11.Immediately unplug the keyboard.
12.The i-Vu server should restart and load as expected.

An MS/TP network can consist of multiple network segments.

Each segment of an MS/TP network must:

• Be wired in a daisy-chain configuration

• Be no longer than 2000 feet (610 meters)

• Have 32 or fewer devices (controllers and repeaters)

• Have one of the following:

○ The End of Net switch set to Yes on the Open controller that is at the end of the network segment. This adds bias and prevent signal distortions

MS/TP communications wiring

Avoiding noise

Avoid running communication wires or sensor input wires next to AC power wires or the controller's relay output wires. These can be sources of noise that can affect signal quality.

igniters Large contactors
transmitters Fluorescent lights
Variable speed drives Parallel runs with power lines
Transformers Video display devices

*If noise is a problem and you cannot move the wiring, use ferrite clamp-on chokes on the cabling to improve signal quality


Troubleshooting an MS/TP network

If you can not discover a controller or have no communication to a device or devices on an MS/TP network:

Verify that the entire segment uses the same baud rate

Verify device check address.

Verify the following aspects of wiring

The shields on all controllers are connected properly. The shield must not touch the metal housing or tie to earth ground.

The cable's outer jacket is not stripped more than one inch. If so, the wires may have become untwisted, causing signal reflections.

The wires are connected correctly to the terminal blocks.

White wire to Net+ (typically, terminal 1 on a controller)

Black wire to Net- (typically, terminal 2 on a controller)

Shield wire to Shield (typically, terminal 3 on a controller)

Verify that your network meets the MS/TP network requirements and the Network segment requirements.No more the 32 devices without a repeater and end of line resisters at both ends.





Addressing summary

16 = Carrier's BACnet Vendor ID
xx = Router's rotary address (Router Address)
yy = Open controller's rotary address (MS/TP MAC Address)


BACnet IP network number = 1600
BACnet device instance number = 1600xx
BACnet device instance name = device1600xx
BACnet MS/TP network number = 161xx
MS/TP MAC address = 0 

Open controllers that are connected to the router:
BACnet device instance number = 161xxyy
BACnet device instance name = device161xxyy
MS/TP MAC address = yy
BACnet MS/TP network number = 161xx (supplied by the router, defaults to 16101 if there is no router.)
If a router’s MS/TP address is set to 200 and the connected Open controllers are auto-generated, 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

Ivu-Open routers are for Carrier Open BACnet MSTP controllers, and the Ivu Open Link will allow for third party integration points of up to 500 points non Carrier.
