i want to do some dynamic labelling on a job with dlts but i am un shore what serial strings to send to the pc interface. I am using crestron to send the strings. When i use dignostics utility i send a label and read it via crestron but wen i get crestron the send the string back the label doesnt change on c-bus and toolkit log records a string error is there something special i need to do to the pc interface to send strings.
