Hard disk and IDE port
The XE–900 has two ATA-4 compliant IDE controllers. The primary channel is
dedicated to the CompactFlash. The secondary channel supports two additional
IDE devices through a 2 mm, 44-pin connector. This connector supplies power to
the devices. Octagon Systems has a 44-pin to 40-pin Hard Drive Adapter cable
(part #4080 or #6246) to connect IDE devices with a 40-pin interface.
USB ports
The XE–900 provides 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. DOS legacy
USB is supported.
Both channels are Universal HCI compliant.
Note that USB devices are hot-swappable when a device is plugged into a standard
USB connector; the 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 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–900 does not provide connectors for LPT parallel port or floppy disk drive.
These functions, if required, can be obtained through USB devices, or PC/104 or
PC/104

devices.
Digital I/O
The 24 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. Each
line can sink or source 15mA. The lines can be individually programmed as inputs
or outputs.
Ethernet
The XE–900 provides one 10/100BaseT Ethernet port and supports the IEEE 802.3
Ethernet standard.
Serial ports protected against ESD
The XE–900 SBC has six serial ports. These ports provide one 8-wire and four 4-
wire RS–232C ports, and two ports of RS–422, RS–485 or TTL. COM5 can be
configured as RS–232C, RS–422, RS–485 or TTL, while COM6 can be configured as
RS–422, RS–485 or TTL.
PC/104 and PC/104
