7.8 PD protocol monitoring
On the hardware, you need to use two CC lines, the connection method is:
PD charger-CC line-FNB38-CC line-PD electrical appliances
In order to avoid losing data, you can use the HID interface to provide power.
When connecting, first connect the charger, FNB38 will automatically judge the
communication CC line and switch to the corresponding interface to monitor.
On the software, select PD monitor and short press OK button. If CC line is not
detected, it will return to the selection page; if CC line is detected, enter PD
monitor page 1 (see Figure 18).
Tip: PD monitoring only judges and switches to the corresponding CC line when
entering. If it has been entered successfully and then HID power supply is removed,
then the CC line connected to the charger is unplugged and inserted reversely. Because
the communication CC line is different, it cannot be monitored. Flip the CC line,
or exit the monitor and re-enter. When the monitoring function is not normal, you
can also go to page 2 to reset the monitoring information.
Because the CC line usually only has a single-sided CC, the two CC lines need
to be communicated with the CC line pair to monitor successfully.
