To set the IP address
You must define the TV-UCXP683T-V's IP addressing (IP address, subnet mask, and default gateway) on the
controller setup Ports tab so that the controller can communicate with the i-Vu Server on the IP network.
Use one of the IP addressing schemes described below with the associated instructions that follow.
Use a...
If...
DHCP IP Address
generated by a DHCP server
The IP network uses a DHCP server for IP addressing
Custom Static IP Address
from your network administrator
You do not use a DHCP server and the answer to any of the
following questions is yes. Will the i-Vu® system:
•Share a facility's existing IP data network?
•Be connected to the Internet?
•Have at least one device located on the other side of an IP
router?
•Be connected to any third-party IP devices?
NOTE Carefully plan your addressing scheme to avoid duplicating addresses. If third-party devices are integrated
into the system, make sure your addresses do not conflict with their addresses.
To set a DHCP IP address
1 On the controller setup Modstat tab, find the controller’s Ethernet MAC address and write it down.
2 On the Ports tab under IP Port, select DHCP.
3 Click Save.
4 Write down the IP Address.
5 Give the DHCP network administrator the IP address and Ethernet MAC address and ask him to reserve that
IP address for the controller so that it always receives the same IP address from the DHCP server.
To set a custom static IP address
1 Obtain the IP address, subnet mask, and default gateway address for the controller from the facility network
administrator.
2 On the controller setup Ports tab under IP Port, select Custom Static.
3 Enter the IP Address, Subnet Mask, and Default Gateway addresses that the network administrator gave
you.
4 Click Save.

12
To set the Port S1 address and baud rate
The address should be in one of the following ranges based on the port's use:
•For MS/TP Master, the range is 0 to 127.
•For MS/TP Slave, the range is 128 to 255.
•For Modbus, the range is 1 to 247.
You set this address on the TV-UCXP683T-V's controller setup pages.
The TV-UCXP683T-V can automatically receive or establish the baud rate on an MS/TP or Modbus serial network.
When you configure a device on the network for autobaud and then power it up, the device detects the incoming
baud rate on the network and sets its baud to match.
Autobaud does not work unless there is a device on the network, whether Carrier or third party, that has the baud
rate already set. You can manually set the baud rate on more than one device, as long as the rate is the same for
every device.
NOTE The discovered autobaud rate stays intact during power cycles.
MS/TP
For MS/TP on Port S1, set up autobaud or the baud rate
•On the controller setup pages > BACnet tab > Port S1
•In the i-Vu® interface, on the navigation tree, right-click your TV-UCXP683T-V > select Driver Properties >
BACnet Controller Properties > MS/TP Configuration on Port S1. See BACnet Controller Properties (page 41).
NOTES
•If not using autobaud, enter the identical baud rate for all devices on the same MS/TP network segment.
•If using autobaud, we recommend you set the baud rate manually on the router for the MS/TP network
segment.
Modbus
For Modbus Serial on Ports S1, set up autobaud or the baud rate
•On the controller setup pages > Modbus tab > Modbus RS-485 > Port Configuration
•In the i-Vu® interface, on the navigation tree, right-click your TV-UCXP683T-V > select Driver Properties >
Communication Status > Modbus Serial.
NOTE For details on setting up your network, see the Modbus Integration Guide.
NOTE If you set Autobaud or make other changes in the controller setup pages, you must upload the changes to
the system database the first time you access the controller in the i-Vu® interface. This preserves those settings
when you download memory or parameters to the controller.

network. You can configure them and assign addresses to each one using one of the methods described below.
NOTE For this discovery tool to work, the controllers must reside on the same subnet and be downloaded with
drv_fwex_107-xx-xxxx or later.
Method 1: To address when you know the serial numbers
1 Connect one i-Vu® XT or TruVu™ device on the IP network to the Service port. For details, see Addressing the
TV-UCXP683T-V through the Service port (page 9).
NOTE This device is referred to as the "connected controller".
2 Browse to the Service Port address (http://local.access or http://169.254.1.1).
3 On the Ports tab, set the device's IP Address, Subnet Mask, and Default Gateway.
4 On the controller setup Local Network tab, verify that the device's address information is displayed at the top
of the page.
5 On the Local Network tab, click the Clear All button to erase the Local Devices table if there is information in
it.
6 Click Discover. The table finds and lists the first 256 unconfigured devices on the same subnet. The table is
sorted by serial number.
NOTE A maximum of 256 i-Vu® XT or TruVu™ controllers can be discovered and displayed in the Local
Devices table. If you have more than 256 controllers on your network, configure some or all the controllers in
the table and click Clear. Check Only Unconfigured and click Discover again. A count appears above the table
to report the total number of controllers and the discovered number.
7 To configure devices:
○One at a time - Enter the IP Address and Location or name (optional) of each device you wish to
configure. When you enter the IP address, that device inherits the original device's subnet mask and
default gateway.
○Multiple devices simultaneously - Select the devices you want to address, enter the starting IP address in
the field under the Address heading, and then click Assign. The selected devices are automatically
assigned sequential IP addresses.
NOTE To change the IP Address, the device's Mode must be Custom Static.
For more details about discovering and configuring your devices, see Local Network tab (page 51).

Method 2: To address when you do not know the serial numbers
You will need physical access to each device so that you can press the DSC button on the bottom right of the TV-
UCXP683T-V. This allows you to identify the device on the controller setup Local Network page.
1 Connect to the Service Port of one i-Vu® XT or TruVu™ IP device on the network. For details, see Addressing
the TV-UCXP683T-V through the Service port (page 9).
2 Browse to the Service Port address (http://local.access or http://169.254.1.1).
3 On the Ports tab, set the device's IP Address, Subnet Mask, and Default Gateway.
NOTES The other devices that you configure inherit this device's subnet mask and default gateway.
4 On the Local Network tab, click the Clear All button to erase any pre-existing data in the Local Devices table.
5 On the controller you want to address, press the DSC button on the bottom right. When pressed, a row
appears in the Local Devices table on the Local Network tab. The row has a blue dot to indicate which
controller has just had the button pressed.
6 In the row for the identified controller, enter the Address and Location (optional).
7 Repeat steps 3 and 4 for each controller that you want to address.
8 For more details about discovering and configuring your devices, see Local Network tab (page 51).
NOTE To physically identify a device that is displayed on the Local Devices table, you can click the Blink button,
which causes that device's Net and Sys LEDs to flash light blue for 10 seconds.
The following are two possible methods you could use to identify and assign a network of controllers' addresses
after following steps 1 - 4 above.
•Two technicians can work together if they are communicating throughout the process. The first technician
physically travels around the building to each controller, tells his co-worker exactly where he is, and then
presses the DSC button. The second technician, who is sitting at a computer connected to the controller,
watches for the blue dot to show up on the Local Devices table on the Local Network tab, where he can enter
the appropriate addressing and identifying information.
•One technician alone can address the controllers on a mobile device showing the Local Network page by
plugging the Carrier wireless service adapter into a controller's Service Port. Then, with the computer, move to
each controller within 100 ft. of the adapter. Pressing the DSC button on the controller displays a blue dot in
the table where the addressing information can be entered.
