Firmware Update
From time to time, Key Digital may provide firmware updates for the KD-VPHD3. These updates
are optional, and should only be performed as instructed by Key Digital. Below is the procedure for
updating the firmware. Please note that incorrect update processes can result in an unusable unit.
Follow the detailed directions carefully.
Firmware Update Procedure
Check our web site at www.keydigital.com for the latest firmware update ZIP file. Download
and unzip the firmware ZIP file to any directory on the PC. All of the unzipped files that are
created must be located in same directory on the PC.
Be sure power is disconnected to the KD-VPHD3 unit.
The power supply must be
disconnected (either from the back of the unit or from the wall outlet) to have a
complete power shutdown - reset.
With power disconnected, set the rear-panel slide switch (see page 5 number 12) to
program mode “Mode A”.
Do not yet apply power to the unit.
Connect an RS-232 cable to the COM1 serial port on the PC, and the other end to the
RS-232 port on the rear panel of the KD-VPHD3 unit. Make sure that no other devices are
using the COM1 serial port on the PC. Use of laptop computers has proven less reliable
than desktop systems. Please refrain from updating the firmware with laptops.
Apply power to the KD-VPHD3 unit.
The power supply must be reconnected to the unit.
Double-click the ‘isynchd.bat’ file from within the ZIP folder. The command mode window
should pop up. Monitor this pop-up window to verify the update progress.
If an error occurs, check the RS-232 connection and repeat all of the above steps.
When the update is complete, disconnect the RS-232 cable between the unit and the PC.
Disconnect power from the KD-VPHD3 unit.
The power supply must be disconnected
(either from the back of the unit or from the wall outlet) to have a complete power
shutdown - reset.
With the power disconnected, set the rear-panel slide switch to “Normal” mode.
Turn on power to the KD-VPHD3 unit.
Power supply must be reconnected to the unit
first; then push the ‘On” button on the front panel.
The firmware update is now complete, and the KD-VPHD3 is ready for operation. Upon
boot-up, the LCD will display the new firmware version
