USB Port Connector (J5)
USB provides an expandable, hot-pluggable Plug and Play serial interface that ensures a
standard, low-cost connection for peripheral devices. Devices suitable for USB range from
simple input devices such as keyboards, mice, and joysticks, to advanced devices such as
printers, scanners, storage devices, modems, and video conferencing cameras. USB 2.0 has a
raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1,
which tops at 12Mbps.
USB port 1 is available on the front panel using a standard connector as shown in Figure 2-10
below. The other two USB ports USB-2 and 3, are routed out the VMEbus P2 connector and can
be accesses either directly off the VMEbus P2 connector using the pin assignment shown in Fig.
2-10. The USB +5 V supplies are protected with a polyswitch. This device will open up if +5 V
is shorted to GND. Once the shorting condition is removed, the polyswitch will allow current
flow to resume.
