/4+ and Hubport/4c+
Hubport/4+ and Hubport/4c+ (compact) are externally powered hubs that connect to a standard USB upstream port.
They both offer four downstream USB PlusPower ports that are compatible with both standard USB and PlusPower
USB devices. Port 1 supplies 24 VDC, and Ports 2 through 4 supply 12 VDC (in addition to the standard 5 VDC
available all of the PlusPower ports as shown in figure 1 on page 1). All of the ports are keyed for their specific
power rating and have cable locking mechanisms to ensure a secure connection to PlusPower peripheral devices. See
Figure 1 on page 1 for a diagram of the different keys.
