I see there are two power input por ts. How do these work?
The Primary DC Input is where you plug the power supply provided with the camera. You
can optionally connect a backup source of power, often a battery, to the secondary backup
input.
With the backup power connected, if there is a loss of power on the primary input, the
backup power will immediately take over. This protects images stored in the camera's
high-speed memory from accidental loss.
When the power switch is set to AUTO, there is no drain from the connected battery
unless a loss of primary power causes the power input to switch to the backup source.
See next FAQ for more information on this.
In case of primary power loss, the backup battery port will not only protect images saved
in memory, but can provide sufficient power to power all camera operations until the input
voltage drops below the minimum required, ~20VDC.
If primary power is restored, that becomes the power source for the camera and the
battery port reverts to backup mode.
How does the AUTO/ON/OFF switch work?
When a 20-28V power source is connected to the Backup DC only, and the switch is set to
AUTO, the camera WILL NOT power up. Connect power to the Primary DC input and the
camera will power up. In this situation, if there is a loss of primary power, then the backup
power will be used to maintain camera operation and protect any stored data.
AUTO is required when a camera is positioned in a hard-to-reach location and requires
a battery backup. This allows for the primary power to be switched on remotely without
drain on the battery until the event of an actual primary power loss.
When the switch is moved to the ON position, the camera will power up whether a
20-28V source is connected to the Primary or Backup DC inputs, or both. When both
are connected the camera always uses the Primary source first before switching to the
backup in the event of a power loss, or if it is a battery dropping below 20V.
ON is typically the better position when using batteries for primary power, as it will allow
them to be switched out without interruption.
Which Phantom power supplies work with T-Series cameras?
The camera ships with a 280 Watt power supply (PSU) and 3-pin XLR to Fischer cable for
power. This is the same PSU that is used with Flex4K and UHS (vXX12/40) series cameras.
Note that early T1340 cameras shipped with a 160W PSU, however Vision Research
switched this to a 280W to be consistent across the T-Series product family.

Do T-Series cameras suppor t the use of Canon EOS lenses
with software control for aper ture and focus?
Yes, an optional Canon EOS lens mount is required, part #VRI-MNT-TSERIES-EOS. Vision
Research can only guarantee compatibility with the lenses listed on the tested Canon lens
compatibility list, which can be found in a FAQ on the phantomhighspeed.com website.
Can the camera be positioned ver tically?
Yes, it can when using the side-mounting bracket designed specifically for T-Series
cameras. Sometimes vertical framing will be beneficial, as it allows for higher frame rates
requiring the full width of the sensor instead of the full height.
It is important to not rest the camera on its side and block the fan compartment, as
constant airflow is required during normal operation. The vertical mounting bracket adds
two 1/4x20 and 3/8" mounting points to the side, while raising the camera to ensure proper
clearance below the fans.
Note that the distance from mounting surface to optical center is not identical to the base
when using the T-Series side mount.

Restoring the factor y defaults
If the camera is stuck in an unusual state it may be useful to restore the camera's factory
defaults. This returns the capture parameters, image processing, video modes and image
calibration back to the original settings.
Factory Defaults can be set in the Nucleus program within PCC, or via the 'Settings' menu
of the OCC. Select 'Factory Defaults' / 'OK'. It will take approximately 20 seconds for the
camera to return to an operational state.
Is there an Optical Low Pass Filter for the T1340?
An Optical Low Pass Filter (OLPF) is an added filter that goes in front of the sensor, meant
to reduce aliasing caused by the bayer pattern of color CMOS sensors, typically with a
pixel size of 10 microns or less. It is a feature often found in cameras used for cinema
applications.
There is no OLPF option for the T-Series cameras. An OLPF is not universal, it is not
possible to use the OLPF designed for a different camera model (like Flex4K) as it will have
no positive effect on the image.
