End of message tests
You can simulate a condition where an end of message bit is placed improperly. The end
of message bit should be placed in the last block of the message. However you can place
the end of message bit in a block that is not the end of message and therefore cause an
incomplete message to be sent since the target device is suppose to ignore additional
blocks once the end of message bit is processed.
To simulate end of message anomolies:
1. Enter the following command to simulate an end of message anomoly.
CEC1:CECT:EOMS 2 //indicates that the end of message bit will be
placed in the second block of the message.
CEC1:CECT:EOMS 1 //indicates that the end of message bit will be
placed in the first (header) block of the
message.
