4. Press “Browse” button to select the corresponding SW bin file to upload
5. Press “Upgrade” button to start downloading the SW and wait the gauge displayed “100%”
that means the SW has been successfully downloaded.
In the meanwhile, all operations such erasing flash and so… are parsed into the debug
window script.
6. Once the SW is downloaded, switch-off/on the chassis board and wait few seconds for
Eeprom update.
Appendix p
“Serial Command Protocol for MTKxx”
1. A serial protocol for driving MTK µchip through external +3.3VDC serial device (USB or
COMx) is available. It may facilitate manufacturing process. Thus, both P201 connector from
chassis board or either VGA input can also be used using pin12 (RXD) & pin15 (TXD) just
taking care that “Factory Key” from Factory Menu is enabled.
2. The required serial port settings are as below
• 115200 bps
• 8 data bit
• 1 bit stop
• none parity
3. The command format is like hereafter described into BNS representation:
• 0xBB + Command + Data[[..] + ..] + 0xEE
Both 0xBB and 0xEE bytes are mandatory and used as header and footer of the
transmitted frame. Apart from INIT frame that is described further, all sent bytes need to be triggered
before by an additional one as 0x50. So a complete frame might match following one:
• 0x50+0xBB+0x50+Command+0x50+Data[[..]+0x50+..]+0x50+0xEE
4. At first time, it might be required to initialize MTK µchip by using once below INIT command
(without any triggering byte):
• 0x02 + 0x00 + 0x00 + 0x13 + 0x01 + 0x00
5. A none exhaustive list of commands is already available.
Appendix q
“ WARM/COOL Relative Matrix Offsets”
1. These offsets should be done in the production by AOE.
