A unit configured to its factory default settings has a default static IP address of 192.168.0.250 and a network mask of 255.255.255.0.
Such configuration will make the device accessible on any local network which uses an IP address range of 192.168.0.* and on which the
192.168.0.250 address is not yet used. Many routers use this address space by default so chances are that the unit will be accessible out
of the box if connected to such a network.
However there is also a high chance that the network on which the unit is connected does not use the proper range of IP addresses and so
the unit’s default static IP is not supported. In such a case the Trinity Polarizer can be accessed by directly connecting it to a PC using an
Ethernet crossover cable supplied with the unit and properly configuring the network settings on the PC.
The following steps need to be taken to make an initial connection to the unit and configure its network settings:
1. First, try connecting the unit directly to the local network to which it will be connected during normal operation.
2. Download the Configuration Utility from XPAND’s website, install it on your PC and run it.
3. Select “Factory default device” from the “Select Device” drop-down list. This list contains all devices known to the utility and should only
contain the “Factory default device” after a fresh install.
4. After confirming the selection an automatic attempt to connect to the unit will be made. This is indicated in the status bar at the bottom
of the utility which should read “Please stand by. Retrieving device data...”. If an automatic connection attempt is not made by the utility,
initiate it manually by clicking the “Get Device State” button.
5. Two situations are possible after initiating a connection:
a. If the application successfully connected to the unit, then information about it will be displayed by the application and the status
bar will read “Device found. Application idle.”. In this case the unit’s default IP is within the network’s IP range and it is accessible
on that network. If you plan on using only one unit on this network then the IP can be left unchanged but must be reserved on
the network to avoid it being assigned to another device when the unit is powered off or disconnected from the network. Consult
your IT department on how to reserve an IP address on your local network. Chances are that this can be configured on the router
however configuration elsewhere on the network may be required.
Once the IP is reserved, network configuration is finished.
If however more devices will be connected to the same network, this unit’s IP must be changed since each device requires a unique
IP. Proceed to step number 6.
b. The application failed to connect to the unit (status bar reads “Device not found on LAN.”). First try to connect a few more times
manually by pressing the “Get Device State” button. Also try restarting the device by unplugging it from power, waiting for 5 s
and then plugging it back in. If this does not help, then the default IP address of the unit probably does not match the available
IPs allowed by the local network to which it is connected. To establish a connection with such a unit a direct connection with
your PC is needed:
»
Unplug the network cables from the unit and from the PC.

On your PC, change your network settings and assign your PC a static IP address of 192.168.0.50 and a network mask of
255.255.255.0. It is important that the IP address has the first three numbers equal to the first three numbers of the unit’s IP
address. These numbers are 192.168.0 when it is configured to factory default settings. For Windows 7 PC reconfiguration can
be done by following below steps:
› Go to
Control Panel -> Network and Sharing Center -> Change adapter settings
› Right-click on
“Local Area Connection”
and select
“Properties”
› Select
Internet Protocol Version 4 (TCP/IPv4)
and click on
“Properties”
› Remember the settings shown in the
General
tab. You will need to restore them once you finish configuring the unit.
› In the
General
tab select
“Use the following IP address”
and enter an IP of
192.168.0.50
, and a network mask of
255.255.255.0
. The Default gateway field can be left empty.
› Also select the
“Use the following DNS server addresses”
but leave the fields empty.
› Click
“OK”
and then
“Close”

Connect the Trinity Polarizer to the PC using an Ethernet crossover cable which is supplied with the unit.
»
From the configuration utility retry connecting to the unit. Only proceed to step 6 once a successful connection has been made.
6. At this step a successful connection has been made to the Trinity Polarizer unit by using the PC-based configuration utility. Its IP address
now needs to be changed to a valid IP for the network on which the unit will be located during normal operation. First, one such IP
address must be found.
»
If possible, you should consult your IT department and have them assign and reserve a free IP address which can be
permanently used by the Trinity Polarizer unit.
»
Alternatively you can try and reserve an IP for the unit yourself by properly configuring the network. In some cases all that is
needed is reserving the IP address on the router, if the unit is connected to one and the network is configured accordingly (see
