USB Plus Series
The USB Plus Series of products are fully compliant with standard USB ports. The PlusPower ports allow for the
attachment of USB devices that draw more than 500 mA, which is the maximum power provided by standard USB
ports. This additional power enables USB PlusPower peripherals to function properly without requiring their own
individual power supplies. These ports also have a cable locking mechanism to ensure a secure connection to
downstream PlusPower peripherals.
Edgeport
®
/42+
The Edgeport/42+ offers four PlusPower USB ports and two RS-232 serial DB-9 ports, allowing for the connection
of PlusPower USB, standard USB, and legacy serial devices in a single box. USB Port 1 supplies 24 VDC, and Ports
2 through 4 supply 12 VDC (in addition to the standard 5 VDC available in all of the PlusPower ports as shown in
figure 1 below).
Cabling the Edgeport/42+
Note that Windows NT 4.0 users must install the drivers before connecting their Edgeport/42+. The Edgeport/42+
operates as a self-powered hub, requiring a power supply to function. For more information about hubs, see the
“Understanding Hubs” section on page 13.

, plug the Type A end of the USB cable into the lower
section of one of the Edgeport/42+ USB PlusPower slots and the Type B end of the USB cable into the peripheral.
2c) To connect a PlusPower USB device to your Edgeport/42+
, plug the type A end of the USB PlusPower cable
into one of the Edgeport/42+ USB PlusPower slots (ensuring that the voltage key on the cable matches the voltage
key of the port) and the other end into the peripheral.
