cordingly (see the router’s user manual for more information). However, depending on your network’s configuration, IP address
reservation may need to be done elsewhere on the network.
7. After step 5, the XPAND Passive 3D Polarization Modulator Configuration Utility should still be connected to the modulator and its IP
address can now be updated with that acquired in step 6. To do so press the “Change Network Settings on Device” button. This enables
changing of network settings on the connected modulator, including its IP address. Enter the new IP address from step 6 in the “Device
IP” field. If the modulator and the device which will be controlling it are on the same subnetwork then the network mask should be set
to 255.255.255.0 and the default gateway setting is not critical. However if they are on different subnetworks, the mask and default
gateway should be configured properly based on your network’s structure. Consult your IT department for help.
8. To send the new IP and other network settings to the modulator press the “Confirm New Network Settings” button.
Warning! If you
assign an invalid address to the modulator you will no longer be able to access it over the network! You will be able to ac-
cess it again by connecting it directly to your PC as described in step 5b) if setting the PC’s static address so that the first
three numbers are the same as those of the modulator’s IP which you have just set. So if you set the modulator’s IP address
to 1.2.3.4 you will only be able to access it directly from your PC as described in 5b), if setting the PC’s static IP address to
1.2.3.* (excluding 1.2.3.4).
9. Since the modulator’s IP has now been changed a new device must be added to the list of known devices inside the configuration utility.
Click the “Add new device” link and enter a device name, its new IP and make sure the port is set to 1000. An attempt to connect to
this device will then be made. If you were configuring the modulator by direct connection with a crossover cable this attempt will fail
and you have to connect the modulator and the PC to their respective networks (make sure to first reset you PC network settings you
may have changed in step 5b).If an automatic connection attempt is not made by the utility, initiate it manually by clicking the “Get
Device State” button.
Once a successful connection is made, device information read from the unit will be updated in appropriate fields of the configuration utility.
Note:
The network may require some time to refresh its list of known devices and accept the new IP address for the modulator. If reconnec-
tion fails, try waiting a minute or two before trying again. You can also disconnect the device from the network during that time.

Parameters listed below are more a function of the DCI server and/or the projector than a function of the modulator so given values should
be taken as reference and modified if the expected results are not obtained:

Modulator Configuration Using the PC Based Configuration Utility
Overview
The XPAND Passive 3D Polarization Modulator Gen2 features a PC-based setup and configuration utility which can be used for changing
advanced settings on the unit. The modulator’s default settings enable it to work out of the box so no configuration is required. However,
based on the system with which the modulator is used, some settings may need to be changed to ensure desired operation.
The PC configuration utility is subject to updates so make sure to check the help file bundled
with each release for up to date information about its features and functionality!
As shown in below image, the configuration utility is made up of six parts:
(1) Device Selection - Selecting and connecting to a modulator.
(2) Device Network Settings - Modulator’s network settings information and control.
(3) Device Information - General information about the connected modulator.
(4) Device General Settings - Information and control of connected modulator’s general settings.
(5) Device Mode Control Settings - Information and control of connected modulator’s settings pertaining to its mode control source.
(6) The Menu Bar - Additional features related to the configuration utility and connected modulator.
