Stereo Phone Jack
f
smin
24 – 160*
Sets the minimal frequency of 3D sync signal at which the system operates in 3D mode. This value
is only used if “Frame sync” is set as mode control source. For “Network” and “GPIO” mode control
source this frequency is hardcoded to 20 Hz.
f
smax
24 – 160*
Sets the maximum frequency of 3D sync signal at which the system operates in 3D mode. This value
is only used if “Frame sync” is set as mode control source. For “Network” and “GPIO” mode control
source this frequency is hardcoded to 160 Hz.
gpiopol
norm / inv
Sets the polarity of the GPIO input signal.
* Parameter f
smin
must be lower than f
smax
Table 2: Recognized Network Command String Macros
Note that there is a known issue when connecting the Trinity Polarizer to Doremi and NEC digital cinema servers which must surround the
string macro with “\w” (without quotes) to ensure proper operation. This introduces a short delay when sending the macro over the network
which gives the unit enough time to receive the command before the server disconnects. An example of a macro which puts the unit in 3D
mode if the “Network Mode Control Source” is already selected is “\w<mode>3D</>\w” (without quotes).
Motion Control Output
In a typical setup the Trinity Polarizer is mounted onto a motorized mount unit which can automatically move the unit in front of and away
from the projector. The “Motion Control Output” on the unit is intended for connecting it to such a mount. It is through this port that the unit
signals the mount to move it away from the projector when operating in 2D mode and to move it in front of the projector when in 3D mode.
The “Motion Control Output” is an open collector, optically isolated output - see diagram
in Figure 5
. By default the output is open when
in 3D mode and closed/shorted when in 2D mode. This polarity can however be reversed by using the PC-based configuration utility. See
