Figure 4: GPIO Mode Control Wiring Diagram
Network Mode Control Source
If the unit is set for this mode control source, it then accepts command macros from over the network, signalling it to move to 3D or 2D
mode. This method is intended for controlling the unit and the optional motorized mount connected to it over the network, by a projector
or digital cinema server.
The unit’s network settings must first be configured so that it becomes accessible over the network. For information on how this is done
see section
Unit’s Initial Network Settings Configuration
. Once the unit’s network settings have been properly configured, its mode can
be controlled by sending string macros to its IP address on port 1000.
Macros are simple strings sent to the unit’s IP address and take the following form:
<command>parameter</>
Examples:
2D mode command macro string:
<mode>2D</>
3D mode command macro string:
<mode>3D</>
The 2D and 3D macros are not the only ones which are accepted by the XPAND Trinity 3D Superlight Polarizer however they are the two most
typically used ones.
Table 2 below summarizes all string macros which are recognized. Most are accepted no matter which mode control
source is selected whereas some only have effect if Network Mode Control Source is set.
The Trinity Polarizer accepts up to 8 commands in one string:
<command1>parameter1<command2>parameter2 … <command8>parameter8</>
Below example shows a string macro made up of two commands - the command to set the mode control source to Network and then set
the unit to 3D mode:
<modctrls>n<mode>3D</>
Command Parameter Value Description
mode 2D / 3D
Sets the currently active mode based on the input parameter value.
Note: This command only takes effect if the “Network Mode Control Source” is selected. If “Frame
Sync” or “GPIO” mode control sources are selected, the command is ignored.
syncpol norm / inv
Sets polarity of 3D sync signal and thereby determines whether high level of the 3D frame synchro-
nization square signal corresponds to the left eye 3D image or the right one.
modctrls f / n / g
Sets the active mode control source.
f – Frame sync mode control source
n – Network mode control source
g – GPIO mode control source
