4.2 Remote Control and singalizing
The PROSWTICH-8 has a 10 pin Phoenix like connector at the back. A simple momentary contact closure
will select the corresponding input. PIN 10 is common for contacts 1-8.
Pin 9 signalizes with 4V that a DVI/HDMI source has been connected, in case of a VGA source the PIN
carries 0V signal level.
A typical control system can detect this change and will allow you to control your display to toggle with the
PROSWITCH-8 between DVI and VGA input.
Another option would be to use the SPATZ DIGISCALE and convert VGA and DVI input signals to DVI or
VGA and scale them to the native resolution to the connected display.
4.3 RESET
The
PROSWITCH-8
is a complicated technical device that may not work as it should because certain
button combinations or serial commands have compromised its internal computer.
In these cases we recommend to repower the unit and remove and replug the mains. It this is not helping
to solve the issue it may be necessary to RESET the unit.
Use the navigation buttons until you reach „Reset to Default „ and then press the right button, when the
Cursor is blinking press the DOWN button for min. 3 secs.
The unit is restarting and shows the current firmware on the LC-display.
After a full RESET all EDID memories hold the Default EDID setting which is a SingleEDID that holds the
1280x720p setting that is widely compatible with most modern displays.
4.4 Firmware Update
It is very simple to update the firmware of the
PROSWITCH-8
. Just download the firmwareupdate *.txt
File from
www.spatz-tech.de
or
www.spatz-tech.com
.
The firmware is a simple text file that you can write into the unit using the Hyperterminal communication
software that is part of any Windows operating system.
We also provide a configuration file for Hyperterminal so your serial port settings are matching those of the
PROSWITCH-8 (57600,8N1).
Once you have launched the program and are connected to the unit, you may verify proper communication
by either sending serial commands by typing them in the hyperterminal or replug power which forces the
unit to send some status messages.
Once you have verified you have a serial communication established you have enter the DEVICE GROUP
and navigate to „SoftwareDownload“. Right button engages verifying with blinking cursor, now hold the
DOWN button for min. 3 sec.
The unit will now run in the update mode, you should have seen status messages in the hyperterminal
windows and the display brightness has been reduced.
Now you can upload the new firmware by executing „send text file“ and selection the *.txt file that you have
downloaded from our website.
In no circumstance should you remove the powercord while updating the unit as the unit will delete the
firmware memory at some point. If that ever happens you will only be able to perform the update again
but the unit might not work properly anymore. Just repeat the above steps !
