BOLDscreen 32 AVI : Getting Started
6
Installation
1.
You may have received a new SD card for use with your existing BOLDscreen 32. This
contains a firmware upgrade and new set of FPGA logic files to support the AVI. Your
monitor must be used with the new SD card
–
just switch the monitor off and replace the
original SD card with the new one, then switch the monitor on again. When the monitor
restarts, the upgrade will be loaded. The upgrade supports the Power Off and Mirror
Mode features that you can select on the AVI front panel.
2.
Situate the AVI in the control room so that the fibre cable connected to the BOLDscreen
32 can reach the rear of the AVI and so that you can easily access the front panel. Do
NOT take the AVI box into the MR room.
3.
Connect the fibre cable from the BOLDscreen 32 directly to the connector marked
“BOLDscreen 32” on the back of the AVI unit. You do not need to
use the DVI fibre
transmitter if one was originally supplied with your BOLDscreen. The AVI contains an
embedded dual-link DVI video to fibre optic converter. Please return the Ophit TX dual-
link DVI to fibre converter module that was originally supplied with the monitor to CRS.
4.
Turn on the power to the BOLDscreen 32.
5.
Optionally, connect a clone monitor to the HDMI output on the rear of the AVI box via a
standard HDMI 1.4 (or above) cable. This monitor should be situated in the control
room, NOT in the MR room.
6.
Optionally, connect your MRI headphones amplifier to the S/PDIF output on the rear of
the AVI with a standard audio optical fibre (Toslink) cable.
7.
Connect the power supply unit barrel connector to the rear of the AVI. Connect the
power cord to the power supply unit and to a suitable wall outlet.
Operation
1)
Connect a suitable video source to one of the four HDMI inputs or the DisplayPort input.
Connect other inputs as necessary.
2)
Configure the output resolution on the source. The native, recommended video input
mode is 1920x1080 at 120Hz, but 1920x1080 at 60Hz is a good choice too. The AVI box
will re-scale other resolutions.
3)
Press and hold the power button on the front of the AVI unit for three seconds to wake-
up the AVI from low-power mode. The power button indicator will change from slowly
pulsing to blinking.
4)
Press the appropriate input select button to choose which input source will be displayed
on the BOLDscreen 32. The same image will also be shown on your clone monitor (if
connected) and the corresponding audio will be played through your MRI headphones
(if connected).
5)
Press the power button once to send video the BOLDscreen 32. It may take several
seconds for the BOLDscreen to switch modes. You may also briefly see the status screen
during this time. The power indicator will be continuously illuminated.
6)
If required, toggle the mirror-mode on and off by pressing the Mirror Mode button on
the front panel of the AVI box. This toggles left/right inversion of the image. This is
useful for presenting correctly-oriented images to patients as they view the BOLDscreen
