The Mobile Expansion Unit (MEU) is an optional proprietary docking connection that allows you to access other types of devices from the system, without making those devices a permanent part of the configuration.

Serial and Infrared Ports
The system has one external Fast Infrared communication port on the system, and an RS-232 serial port on the MEU. Both ports are implemented with a 16550A compatible serial controller.
The Infrared controller supports a data rate of up to 4Mb/s, in addition to 115Kb/s and other popular slower speeds.  ***Infrared version TBS***
The serial port uses an industry standard 9-pin "D" type connector.
Parallel Port
The MEU has one IEEE-1284 industry standard parallel port that uses a standard 25 pin "D" type connector.  The port can be programmed to operate in Compatibility Mode, Enhanced Modes, Bi-Directional mode, and Extended Capability Port Mode. The default is Bi-Directional mode.
USB Port Support
The system has a two-channel USB hub controller that provides two USB Rev 1.1 ports to the system, and two USB Rev 1.1 ports to the MEU. All ports support 500ma.
The system uses a special 5-pin USB connector, which provides support for four USB ports as well as the Selective Suspend (C3) power management state under Windows 2000.  The fifth pin is used as a sense line to sense the physical connection to the USB hub. The hub has a q-switch that connects and disconnects devices to the 440MX root controller.  ****To be verified****
 
 
This configuration results in a Generic USB Hub to be displayed in the Device Manager when a USB device is connected to the system.  This is normal for this system.
