How can i get data and states of my unit (BK AVR 505) over 232. The protocol is somewhat confusing to me. Once the receiver sends me a string of data how can i pull that data out of the string ?

Example If i need feedback for volume level.

Does anyone know the commands?

That should have been covered in Programming I.

You get the string data from a DATA_EVENT.

If you go to the help menu and search for it, you'll see the syntax and whatnot.

hope that helps

As Eric says, you can use the string handler in the data_event or alternatively you can create a buffer and then parse the result to gain the information you need.

It is well worth the time spent in learning how to parse a string using the tools available in Netlinx - there are many ways and very few are "wrong" - searching on these forums for parsing will give you many a pointer.

Look at LEFT_STRING, MIDSTRING & REMOVE_STRING for starters

CODE

PROGRAM_NAME='AVR505 Sourve'

Define_Device
dvtp = 10001:1:1
dvBK = 5001:1:1



DEFINE_START
data_event [dvBK]
{
String:
{



What do i type here to get the data from the string?
