5.1. Using without connecting to a host
When the Hub is switched on and is not connected to a local host computer it is automatically
configured to charge devices using its intelligent charging algorithm. Connect the devices to be
charged to any of the available ports (not the Host Port) using USB - compliant cables.
Once the devices are connected, the algorithm will detect the highest charge rate allowable for each
attached device. Charging at the optimum rate (up to 2.4)A specified by the manufacturer will
commence once profiling is complete. Depending on the state of charge of the device attached, this
may take tens of seconds.
5.2. Using when connected to a host
5.2.1
Connecting the Hub to a host computer
You can use either Thunderbolt™ host port on the rear of the hub to connect to your host system;
there are two ports on the rear, so you can use one port to connect the host and the other port to
daisy chain multiple hubs.
5.2.2
Charging
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. If the attached device complies with USB-IF Battery Charging specification BC1.2 and
supports Charging Downstream Port (CDP), the hub can provide high-speed charging at 2.4A. If the
connected device does not comply with BC1.2, the charge current will be limited to 500mA 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. You can disable CDP through NVRAM settings either by going through the advanced
settings and turning "Sync charge" off or through the API and disabling it via code. For example, the
instructions would be below using the command line.
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_unlock\nsettings_reset\n-
settings_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")
