5.2. Using when connected to host
5.2.1 Conexión del hub a un equipo host
Connect the PDS-C4 to your host system using a USB 2.0 tipo C cable. El uso de un cable de host
incorrecto puede dar lugar a que el hub y todos los puertos posteriores no sean reconocidos
por su host.
5.2.2 Cargando
When the Host Port is connected to a local computer, the hub defaults to Sync mode and
charge currents are determined according to USB Implementers Forum (USBIF) Super-Speed
USB3 specifications. Si el dispositivo conectado cumple la especificación de carga de batería
USB-IF BC1.2 y admite el puerto posterior de carga (CDP),
el hub puede proporcionar carga de alta velocidad a hasta
high-speed charging at 3 A. If the connected device does not comply with BC1.2, the charge
current will be limited to 500 mA in compliance with USB specifications.
If you wish to limit the charging to your devices whilst connected to your host system then you
can disable CDP on all ports by inputting the following commands.
The CLI commands for turning off the sync charge options, with a 1 or 0 per port.
settings_unlock
settings_reset
settings_set sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
settings_set alt_sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
reboot
This can also be done via the API if this is easier. Just supply that string (joined with \n) like:
cbrxapi.cbrx_connection_set(handle, "Settings", "settings_unlo-
ck\nsettings_reset\nsettings_set sync_chrg 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0\nsettings_set alt_sync_chrg 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0\nreboot")
Note that settings_reset clears any previous settings, so if you need to retain something else, it
would be better to issue settings_display first, which gives you the entire settings which you
can then modify and re-issue in entirity.
