Chapter 12: USB
Description
Universal Serial Bus (USB) is a hardware interface for 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 (see Caution below). The XE–900
SBC contains two USB 1.1 compliant ports.
The USB ports are accessed via a 10-pin, 0.1” pitch connector at J19 (USB 1 and 2).
Octagon provides a cable that routes the J19 signals to standard USB connectors
(Octagon p/n 6288). This cable consists of two five-pin connectors that mate with
the J19 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 J19. 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 (J19). You can hot swap a
device through the USB Adapter cable connected to J19, or through
another USB connector wired to the 10-pin header, but you cannot
hot swap at the 10-pin header itself.
