TVP-500F Installation Manual
9 Firmware and Startup Picture update
The internal software of TVP-500F (the firmware) can be updated. This may be necessary to fix errors in
previous releases of the firmware, or to enhance functionality. The similar procedure is used to update the
“logo picture” that can be shown by TVP-500F for a predefined time after power on.
For the update procedure the serial port of the TVP-500F must be connected to the RS-232 (“COM”) port
of a PC-compatible personal computer, running MS-Windows 98, 2k, or XP operating system.
Update procedure
1.
Connect the Plasma to a PC using a 9pin-to-9pin RS232 cable.
2.
Use the AXLdr.Exe utility to upload firmware or logo picture. This utility is a Win32 command
line (console) application. It can be run from within any application that allows specifying
command line (the simplest example is Windows Start\Run dialog). The command line syntax is:
AXLdr.Exe
<port_number>
<filename>
where
<port_number>
is a COM port number to which the TVP-500F is connected (1-based,
that is, for COM1 this number is 1).
<filename>
is the path and name of the file to be uploaded. Must be either *.BMP file
(bitmap) or *.ATF (TVP-500F firmware) file.
Example command line to load new bitmap file or to update the Firmware:
C:\TVP500F\AXLdr.Exe 1 logo1.bmp
C:\TVP500F\AXLdr.Exe 1 TVP500F.ATF
In this case, COM1 port is used to upload the new logo (logo1.bmp) or the new FW (TVP500F).
After the successful update, the TVP-500F firmware will restart automatically.
Note: to upload a file or a newer Firmware to TVP-500F, the loader (AXLdr.exe) and the file must
be stored in the same directory.
If the loaded firmware image is not valid (its header or checksum do not match the expected), this
firmware will not be loaded upon startup. Instead, the unit will remain in bootblock, which will wait
for the new firmware image to be uploaded again. This is indicated by LEDs “alternate” blinking
low/high/low/etc.
File format for logo picture BMP file
AXLdr.Exe supports conversion and loading of standard 24-bit unpacked RGB MS *.BMP files. The
recommended picture size is 852x480 pixels (width is 852 pixels, height is 480 pixels). Only one
picture can be uploaded and used as logo.
