Instruction Mode
Into set up mode
:
Trans mit value=0x01+0x02+
~
+7E+0x7F,total=127Bytes .
Receive value =0x01+0x02+
~
+7E+0x7F, total=127Bytes
,
and it trans it 0x53
hint notes every s econd to tell us er that it is on ins truction mode.
It needs to be in the s et up mode to read or amend any parameter.
Exit code mode
:
Trans mit value = 0xFF FF FF 55 CC
Receive value = nothing, it s top trans it back 0x53 hint notes every s econd.
It needs to be in the s et up mode.
Read in product name and model
:
Trans mit value =0xFF FF FF 55 AA BB FD
Receive value (no character) =TRW-V8_V001
It has information total in 11Bytes , the firs t s ix characters is product
name and las t four characters are firmware.
Recover parameter
:
Trans mit value =0xFF FF FF 55 AA BB FF
Receive value = nothing
Delete the original parameter, and recover back to the new s et code
that is written in when it is out from factory.
Read in inside parameter
:
Trans mit value =0xFF FF FF 55 AA BB FE
Receive value =
0xFE03 00 00 00 00 05 0E 1D 48 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 s et ins ide parameter at
pres ent.
Set inside parameter
:
Trans mit value =
0xFE 03 00 00 00 00 05 0E 1D 48 07 00 00 FF FF FF FF FF FF FF
FF FF FF FF FF FF FF FF FF FF FF FF
,
It trans it 32 Bytes in total.
Receive value =
0xFD 03 00 00 00 00 05 0E 1D 48 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 trans it back. It
means it is s ame as the ins ide parameter if the firs t Byte s hows FE, after it
finis h the update.
It is 31Bytes in total, change every parameter.
The firs t Byte: the s tarting parameter, fixed to 0xFE
The s econd Byte:
checks um, s top bits , interface s peed rate, s et up range
00
~
07, the beginning rate is 9600bps .
