serial.txtS
The serial diagnostics allows the user to test the selected COM port by displaying sent (black
text) and received data (red text).
The <F1> “Start Hardware Test” transmits 10 characters. It reads back a byte based on the CTS
signal. For this test an external Adapter with shorted pins is necessary. Note that serial data dis-
play is only available with serial data transmission configured as “Standard” or “CT01 3964R”.
The Clear Screen <F2> soft key will clear the displayed bytes
The <F3> soft key toggles the transmission record display between ASCII and hexadecimal.
