Chapter 13: USB
Description
Universal Serial Bus (USB) is a hardware interface for low-speed
peripherals such as the keyboard, mouse, joystick, scanner, printer, and
telephony devices. USB 1.1 has a maximum transfer rate of 12 Mbits/sec.
Peripherals can be plugged in and unplugged while power is applied to
the system. The PC–600 contains two 1.1 compliant USB ports.
The two USB ports are accessed via a 10-pin, 0.1” pitch connector at J3.
Octagon provides a cable that routes the J3 signals to standard USB
connectors (Octagon p/n 6288). This cable consists of two five-pin
connectors that mate with the J3 connector on one end, and two USB
connectors at the other end. Ensure that the arrow on the five-pin
connectors is matched to the pin 1 end of J3. Any USB device can then
plug into either USB interface on the USB adapter cable, or into a multi-
port hub that then plugs into the USB adapter cable.
An operating system capable of utilizing the USB ports and USB devices
is required for USB operation.
Caution
USB devices are hot-swappable when a device is plugged
into a standard USB connector, as pins on the connectors
determine the order in which they make contact. Devices are
not hot-swappable when connected to a non-standard header
(J3). You can hot swap a device through the USB Adapter
cable connected to J3, or through another USB connector
wired to the 10-pin header, but you cannot hot swap at the
10-pin header itself.
