Universal Serial Bus Port 50
Universal Serial Bus Port 6
The pen tablet provides a Universal Serial Bus (USB) port that is compliant with the Universal Serial Bus
Specification Revision 1.0. The USB port is a powered USB hub and can support concurrent operation of up
to 127 devices. The Stylistic 3500 pen tablet functions as a USB host and supports high-power,
bus-powered functions as defined in the USB specification. System resources for the USB are assigned by
the operating system, no software configuration is necessary; however, it may be necessary to install
drivers and application software to support your USB device.
The Stylistic 3500 port replicator and mini-dock provide one USB port. The pen tablet can supply a
maximum of 500 mA at 5 volts (or a 5-unit load as defined by the USB specification) on each USB
connector (for a total of 1,000 mA using both USB connectors, one on main unit and the other on the port
replicator, or mini dock, or high usage cradle, or wall mount cradle).
Ensure that your USB configuration does not exceed this maximum load. Note that the conductor gauge
and length of your USB cabling will affect the voltage drop and signal propagation between USB devices.
Refer to the Universal Serial Bus Specification for details on cable requirements or contact your cable
vendor. Also note that some USB devices are self-powered and do not draw power over the USB cable.
Contact pin assignments for the USB port are shown in Table 6-5.
