Instruction Mode

 Into set up mode：

Transmit value=0x01+0x02+～+7E+0x7F,total=127Bytes.

Receive value =0x01+0x02+～+7E+0x7F, total=127Bytes，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 = nothing, it stop 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 11Bytes, the first six characters is product

name and last four characters are firmware (the contents will be a little

different in different version).

 Recover parameter：

Transmit value =0xFF FF FF 55 AA BB FF

Receive value = nothing

 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 =0x03 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 31Bytes, 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 transit 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 first Byte shows FE,

after it finish the update.

 It is 31Bytes in total, change every parameter.

 The first Byte: the starting parameter, 0xFE

 The second Byte: interface speed rate, set up range 00～07, the
