USB ports
The CS5530A companion chip supports two USB 1.1 channels, accessed through a
10-pin header. USB 1.1 provides speeds up to 12 Mbps. The Octagon two-port USB
cable (part #6288) provides a direct connection from the 10-pin connector to two
USB devices. USB is available when using an operating system that supports USB.
There is no support from Octagon for DOS legacy USB.
Four additional 2.0 USB channels are supported by an on-board PCI-to-USB
controller. These channels are accessed through standard USB connectors. USB 2.0
provides speeds up to 480 Mbps.
All six channels are open HCI compliant.
Note that 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.
You can hot swap a device on the four 2.0 connectors; through the USB connector
on the two-port USB cable; or through another USB connector wired to the 10-pin
header, but you cannot hot swap at the 10-pin header itself.
LPT and floppy
The XE–800 does not provide connectors for LPT parallel port or floppy disk drive.
These functions, if required, can be obtained through USB devices. For DOS
operating system they can be obtained through PC/104 or PC/104
Plus
devices.
Digital I/O
The 48 digital I/O lines will interface with logic devices, switch inputs, LEDs and
industry standard opto module racks. The I/O lines are 0–5V logic compatible.
They can be individually programmed as inputs or outputs.
Ethernet
The XE–800 provides one 10/100BaseT Ethernet port and supports the IEEE 802.3
Ethernet standard.
Serial ports protected against ESD
The XE–800 SBC has two serial ports. COM1 and COM2 both provide RS–232C.
COM2 also supports RS–422 and RS–485 interfaces. COM1 and COM2 are routed
through a 20-pin connector for RS–232C. RS–422 and RS–485 are provided through
a separate 5-pin connector.
PC/104 and PC/104 Plus interface
The PC/104 interface accepts an 8- or 16-bit PC/104 expansion board. The PC/104
Plus
accepts industry-standard PC/104
Plus
boards. PC/104 expansion boards are
available from several manufacturers. Up to four PC/104 or PC/104
Plus
expansion
boards may be stacked on the XE–800 SBC.
