Troubleshooting
Changing the output frame rate
Most monitors and HD televisions can display all the many
different standards of HD signals, however some cannot.
If your monitor/TV does not display the image from the
EVO Cam you should try the following: ensure EVO Cam
is turned off. Press and hold the Overview and power
buttons until 4 quick beeps are heard. This will change
between 50Hz and 60Hz modes and display the selected
frequency. Press any key to continue using EVO Cam.
Taking care of your EVO cam
Do not touch the lens. Dirt on the lens will appear as a
blurred or dim image or as fuzzy spots on the screen. If you
believe the lens is dirty, it can be cleaned with a soft, dry
cloth applying minimal pressure. As the lens is polished and
coated, do not use a wet or coarse cloth, avoid detergents
and abrasive substances or solvents to clean it.
Never look directly at the LED light source for any
prolonged period of time.
Use only the supplied power supply and inspect the
cabling regularly for damage.
EVO Cam contains a small battery to enable
time and date settings to be retained while the
unit is powered off. Should the battery need
replacing please contact you Vision Engineering
representative who will be able to advise you.

FIRMWARE UPGRADE
www.visioneng.com/support
13
FIRMWARE UPGRADE
Firmware upgrade
EVO Cam includes a Firmware Upgrade Function
allowing users to install new versions of the rmware.
`Make a directory called “Upgrade” in a USB memory
stick. If the directory already exists then delete all the
.bin les from that directory.
`Copy the two upgrade les to this “Upgrade” directory.
The les should be in the format “ARMxxxx.bin” and
“FPGAxxxx.bin”. The “xxxx” shows the version number.
`To enter the Firmware Upgrade Function, power up
the system with the front panel Zoom In and Zoom
Out buttons pressed.
`The system will make a sequence of 5 beeps upon
entry to the Firmware Upgrade Function.
`A beeping sound will be emitted until a USB Flash
Drive is detected. If no drive is detected the system
will timeout after approximately 20 seconds and turn
on normally.
`To exit the Firmware Upgrade function before the USB
drive is detected, simply power cycle the system by
pressing the Power Button.
`When the USB memory stick is detected, the Firmware
Upgrade Function searches the “Upgrade” directory
for the 1st le with the name format “ARMxxxx.bin”
and upgrades the ARM processor.
`The Firmware Upgrade Function then searches for
the 1st le with the name format “FPGAxxxx.bin”
and upgrades the FPGA Firmware.
`NB:- The Firmware Upgrade Function will use the 1st
le with the correct name format it nds. Therefore
it is recommended that you only have the rmware
version that you want to install in the “Upgrade”
directory and not multiple versions.
`During the upgrade process beeping sounds will be
emitted indicating progress.
`When the upgrade is complete the system will
automatically restart with the new version.
Lighting controller rmware update
In addition to the standard upgrade, the light control
can be upgraded with new rmware. To upgrade the
light control rmware:
Copy the EVOLxxx.bin into the Upgrade directory on a
USB drive.
Power off the system, then press and hold the Menu,
Zoom in and Power button until 4 quick beeps are heard.
The system will start normally until the USB ash drive is
detected; it will then enter the light control upgrade mode
and display “UPGRADE IN PROGRESS” and emit a number
of beeps whilst the upgrade is uploaded and applied.
When the upgrade is complete the unit will emit a longer
beep and briey display “UPGRADE FINISHED”.
Use the illumination controls to re-set the illumination
level after the upgrade.
Important
If the USB memory stick is removed during the upgrade
process or contains a corrupt le, the system will not
restart and the upgrade process will have to be repeated.
