PHY root menu

The root menu offers the possibility to enter a payload and send the frame in physical layer

mode, as represented Figure 10.

Figure 10. PHY root panel

On this panel, three main actions can be done:



PD_DATA.Request: command to send data at the PHY level



PD_DATA.Confirm: forces generation of a confirmation message (if automatic event is

disabled)



PD_DATA.Indication: forces generation of an indication message (if automatic event is

disabled)

Data shall be specified in the hexadecimal or ASCII format, selecting the proper button.

Note that, in case of the Hex format, if the payload is entered manually, the payload length

must be even (each character corresponds to 4 bits, allowed characters are “0 - 9" and

“A - F”).

A random payload may be generated clicking the “Generate Random” button. In this case, if

the Max Payload Size option is checked, the random payload has a fixed length as specified

in the text box, otherwise a random length is generated and used (length is always less or

equal to the specified maximum).

When the PD_DATA.Request command is executed, messages are logged into the trace

window.
