	USBXpress for WinCE50 1.3.1 - May 13, 2008


Installation Instructions
-------------------------

1. Copy the SIUSBXP.DLL and SIUSBXP.REG files the the \Windows directory on
	the CE device.

2. Plug in the CP210x Device with VID 10C4 and PID EA61. If your cP210x still contains the
	default VID and PID (10C4, EA60) use the CP210xSetIDs.exe application in located
	in Application Note to change the PID to EA61. AN144 and its software package (AN144SW) are
	available here: 

	http://www.silabs.com/tgwWebApp/public/web_content/products/Microcontrollers/en/mcu_applications_appnotes.htm
 
3. When the dialog pops up saying "Unidentified USB Device" enter SIUSBXP for
	the driver name. The dialog should close when OK is pressed, and the LED on 
	the CP210x development board should be lit. (If the dialog doesn't pop up, but 
	the LED on the CP210x development board is on, then it automatically found the 
	device)

4. The two included test applications can now be run (CP210xWinCETest.exe and 
	CP210xWinCEtoWindowsHTTest.exe) using the CP210x in loopback mode. To put the
	device in a loopback state, disconnect the two jumpers for TXD and RXD, and reconnect
	one jumper joining the TXD and RXD pins closest to the USB port - see Figure 1. Under
	Normal Operation, running CP210xWinCEtoWindowsHTTest.exe will write to HyperTerminal
	when hooked up via a Null Modem Cable.
