Communications Diagnostics
The following example of a communications DUMP mode printed out. The printout displays hexadecimal data
The blank lines between the lines of data are where serial port and Bluetooth data handling errors get logged. The errors are:
•F = Frame Error
•P = Parity Error
•N = Noise Error
•O = Data Overrun Error
To exit the diagnostic mode and resume printing, turn off and then turn on the printer. An alternate method for exiting the diagnostic mode is to press the Feed button as many times as it takes to clear the printer’s command buffer and print ‘Out of DUMP’ on the label.
