
Instruction Mode

Into Set-up mode
Transmit value = 0x01+0x02+~+7E+0x7F, total=127 Bytes.
Receive value = 0x01+0x02+~+7E+0x7F, total=127 Bytes, and it transit 0x53
hint notes every second to tell user that it is on instruction mode.

It needs to be in the set-up mode to read or amend any parameter.

Exit Code mode
Transmit value = 0xFF FF FF 55 CC
Receive value = None, it stops transit back 0x53 hint notes every second.

It needs to be in the set-up mode.

Read in Product Name and Model
Transmit value = 0xFF FF FF 55 AA BB FD
Receive value (no character) =TRW-V8_V001

It has information total in 10 Bytes, the first 6 characters is product
name and last 4 characters are firmware.

Recover Parameter
Transmit value = 0xFF FF FF 55 AA BB FF
Receive value = None

Delete the original parameter, and recover back to the new set code
that is written in when it is out from factory.

Read in Inside Parameter
Transmit value = 0xFF FF FF 55 AA BB FE
Receive value = 0xFE03 00 00 00 00 05 06 9F 50 07 00 00 FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF (this is the out from factory
mode)

It has information that totals in 32 Bytes, it is set inside parameter at
present.

Set Inside Parameter
Transmit value = 0xFE 03 00 00 00 00 05 06 9F 50 07 00 00 FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF, it transits 32 Bytes in total.
Receive value = 0xFD 03 00 00 00 00 05 06 9F 50 07 00 00 FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF FF FF, it is 32 Bytes in total transit
back. It means it is same as the inside parameter if the 1
st
Byte shows FE,
after it finish the update.

It is 32 Bytes in total, change every parameter.

The 1
st
Byte: The starting parameter, fixed to 0xFE

The 2
nd
Byte: Checksum, stop bits, interface speed rate, set up range
00~07, the beginning rate is 9600bps.
