General Programming
Command Programming
Commands under RS232 connection mean using 0x20-0x7D
（
the displayable characters
）
to express all
commands information.
Con fi guration State 1
、
The engine should be in con fi guration state when programming functions under RS232 connection.
In the state, the engine would only accept and execute the commands from communication and feed
back.
Sending certain command to the engine will make it enter or quit the con fi guration state. Or if in
con fi guration state the engine hasn
’
t received new information for fi ve seconds, the engine will quit the
state automatically.
Express Regulation 2
、
Sending
“
$$$$
”
and receiving
“
@@@@
”
mean entering con fi guration state successfully.
①、
Sending
“
%%%%
”
and receiving
“
^^^^
”
mean quitting con fi guration state successfully.
②、
Receiving
“
^^^^
”
in con fi guration state means that the engine has quitted the state automati-
③、
cally.
In con fi guration state, every command begins with
“
#
”
and ends with
“
;
”
.E.g.
④、
“
#99900030;
”
In con fi guration state, if the command is executed successfully, the Host will receive a com-
⑤、
mand which begins with
“
!
”
and ends with
“
;
”
. E.g.
“
!99900030;
” 。
In con fi guration state, if the command is invalid or executed unsuccessfully, the Host will
⑥、
receive a command which begins with
“
?
”
and ends with
“
;
”
E.g.
“
?99976543;
”
In con fi guration state, if commands of query type are executed successfully, the host will receive
⑦、
“
! xxxxxxxx
； ”
as well as the feedback which begins with
“
&{
“
and ends with
“
|
”
. In the last
nine characters in feedback, such as
“
|BF7974B7
”
,
“
|
”
is the separating character which separates
the feedback information and check value. And other eight characters
“
BF7974B7
”
are CRC32
’
s Hex
value and arranged from the highest position to the lowest. The feedback information is placed between
“
{
“
and
“
|
”
. E.g.: Sending
“
#99900301;
”
and receiving
“
!99900301;&{Firmware v1.7.5;Decoder
v1.00.023.C6;|FD25430B}
”
If feedback information may have undisplayable characters, it will be expressed in hexadecimal nota-
tion. Two characters represent a character value. E.g.
“ ＆
{AAAA100423C5008001FF400001FF400001FF400001FF400001FF4000000040800000

F400006FF400006FF400006FF400004FF400004FF400002FF400004FF400004FF400004F

”
In con fi guration state, if a command is with parameters, it will be composed following the rules
⑧、
which command system de fi ned. For example, the command string which has 0x0D and 0x0A as ending
character and be saved is
“
#99904112;#99900000;#99900015;#99900000;#99900012;#99900020;
” 。
