RS232 communication issue by sending Ascii

[Albert.lu]

Hello All,

Now I am working on a project about zigbee which is powered by 24V AC.so I need to control the AC power which can be communicated by RS232.

Most of setup steps are set succussfully,except send "D0:0650:0400:0600:2200:0150:0500:4600:0100:0:0/  "

I tried many solutions to write this string, convert into Hex then send,or send this string separately,send D0 first,then send :650 etc...

However,sometimes the eqipment can be controlled,sometime it can not.

Any hints are appreciated,thanks

Most of setup steps are set succussfully

... and what error do you get on the odd one?

Hi Albert,

what you named "protocol" is just example data without any explanations.

Your "D0:..." string looks ok, it's just plain ASCII data. This "OK" answer is also plain ASCII.

Don't you have a more detailed manual with some real protocol descriptions? If not ask your vendor for this manual!

Hi GerdW,

The communication protocol is written by Chinese which is attached.

发：means send command

收：means receive response

Please take a look at "2.参数设定" ，only this step always get error after write "D0:0650:0400:0600:2200:0150:0500:4600:0100:0:0/" ,not get "OK/" response.

There is no issue on write/read others steps except "2.参数设定 ".

Thanks

Best regards

Albert

You should post to the Chinese board unless you can provide an English version of the manual.
