Hi,
Hope someone can help me out…
I want to controll a device with rs232 with a usb to seral converter.
When i operate the device i get feedback from the device in the log…
When i want to send a command i need to add a at the end…
somehow i cant get this to work… I tried every know variant: \r, \r, 0xD \0xD,,<CR>,…
no luck…
anybody got a hint on how to get this to work?
Thanks!
Hi Mathias
I don’t work with that binding. But I think you should provide some more details what kind of device you like to control, and what you have configured (item aso.), in order to get help.
And I think it is related to the specs of your device, what end character is needed.
Cheers
Stefan
Hi Stefan,
Thans for your quick reply…
The device i want to controll is an amplifier with rs232 controll…
I need to send “set master 50” to set the volume to 50
I have an Item “String Champ {serial=”/dev/ttyUSB0@19200"}"
When i change the volume on the amp my log shows that the string “champ” changes
So i do have connection with the amp.
but i cannot sent a command to the amp and i think it has to do with the at the end…
Cheers
Mathias
Hi Mathias
would be good to have the log from the binding in DEBUG mode. To see what the amp sends.
Maybe you would need a \n - but it is really difficult as I have no idea what it expects to receive.
Do you by chance talk about Audac AMP523MK2?
taken from the manual at audac website:
Example
Set volume in zone 2 to -30dB
Command #|X001|F001|SV01|30|58ab|return
Answer #|F001|X001|SV01|+|ead6|return
Update #|ALL|X001|V01|30|aa95|return
where SV01 refers to Master Volume
Important
hope that helps
Cheers
Stefan
So for the reference
Not sure if the changes got added to the serial binding, check this thread out.
