I am currently trying to receive a Hex as ASCII message from an instrument over RS232 on a V700. Currently to simulate I have been sending the expected messages over serial, but in the future the data will be constantly streaming. The Index of Received from the Scan Protocol keeps giving me a -1, indicating an invalid message and I can't seem to understand why. Anything should help at this point.
The measurement packet contains 24 bytes, 2 bytes for the beginning, 1 byte for the checksum, and 1 byte for the end of packet, as indicated by the instrument and reflected in the Scan Protocol.
