1. Introduction  
About this Guide  
This guide provides the information needed to use the XPort and XPort Pro device  
servers with the Universal Demo Kit. The intended audience is the engineers  
responsible for integrating the XPort into their product.  
Notes:  
For evaluation of Evolution OS based turnkey application, one would require the  
XPort Universal Demo Kit (Lantronix PN: XP10010NMK-01) and a XPort Pro with  
Evolution OS sample (Lantronix PN: XPP100200S-01R).  
For evaluation of Linux OS based turnkey application, one would require the  
XPort Universal Demo Kit (Lantronix PN: XP10010NMK-01) and a XPort Pro with  
Linux OS sample (Lantronix PN: XPP100300S-01R).  
For evaluation of XPort Cobos OS based turnkey application, one would require  
the XPort Universal Demo Kit (Lantronix PN: XP10010NMK-01) and a XPort with  
Cobos OS sample (Lantronix PN: XP100200S-03R).  
The XPort Pro Linux SDK (Lantronix PN: XPPDK1000-LNX-01) provides  
hardware, development environment and sample applications for developing  
Linux based applications. An XPort Pro Development Board with a Background  
Debug Mode (BDM) connector option is included with the Linux SDK.  
The XPort Pro Evolution SDK (Lantronix PN: XPPDK1000-EVO-01) provides  
hardware, development environment and sample applications for developing  
Evolution based applications. An XPort Pro Development Board with a  
Background Debug Mode (BDM) connector option is included with the Evolution  
SDK.  
A separate USB BDM Debug Probe (Lantronix PN: 930-060-R) is available for  
use with the XPort Pro Linux and Evolution SDKs.  
Terminology  
Demonstration (Demo) Board  
The Demo board included in the XPort Universal Demonstration Kit is a circuit board that  
the XPort, XPort Pro, or XPort Pro Dev board would be installed on. This board has a  
power supply connector, UUT socket, RS232 transceiver, and DB9 serial connector. A  
power supply and necessary cables are included with the Demo Board in the XPort  
Universal Demo Kit.  
Development (Dev) Board  
The XPort Pro Dev board is a single PCB version of the XPort Pro module without a  
mechanical housing. This PCB has all of the circuitry included in the standard XPort Pro  
module plus a connector for use with a USB BDM Debug Probe. The XPort Pro Dev  
Board is included in the XPort Pro SDKs. In addition the SDKs include the XPort  
Universal Demo Kit.

2. Demonstration Kit  
Using an XPort sample and the XPort Demonstration Kit, you can get familiar with the  
product and understand how to integrate the XPort into a given product design.  
Contents of the Kit  
The XPort Demonstration Kit contains the following items:  
XPort Demo Board  
3.3V wall adaptor  
RS-232 cable, DB9F/F, null modem  
Note: You must obtain an XPort sample separately for use with this Demonstration  
Kit.  
Note: Development Kits for Evolution OS and Linux include the Demonstration Kit  
and the XPort Pro Dev Board (w/ BDM connector port). A USB BDM Debug Probe  
may be purchased separately.

Demo Board Description  
The XPort Demo Board provides a test platform for the Lantronix XPort device server  
products, including XPort and XPort Pro. The demo board uses 3.3V power from the  
wall adaptor same as that of XPort. The demo board has the following features:  
1 serial port with a 1Mbps RS232 transceiver connected to a DB9 serial port  
connector  
Access to all IO signals on the XPort via header pins for measurements and  
connections to other places.

Serial Interfaces  
The demo board has an RS-232 transceiver for connection to the XPort internal  
UART. The table below lists the RS232 signals and corresponding pins on the demo  
board. All signals are level-shifted by the transceivers.

2 Demonstration Kit  
Power Supply  
The demo board uses an external 3.3V regulated supply (included with kit).  
General Control  
The following tables denote the configuration of the demo board. Configuring the  
jumpers re-routes signals on the demo board to use as Serial control signals, or to  
connect to other places on target board as General Purpose IO (GPIO).

Jumper 3-4, Send RTS to RS232 transceiver. For  
connection to an additional RS485 transceiver, RTS  
would be used to drive the transceiver TX enable.

Jumper 5-6, Send DTR/CP2 to RS232 transceiver.  
Jumper 7-8, Receive RXD from RS232/485 transceiver.  
Jumper 9-10, Receive CTS from RS232 transceiver.  
Jumper 11-12. Unused, auxiliary transceiver receive port.

Note: CP arrangement in the tables above is for demonstration purposes only. All  
CPs can be used as GPIOs. In XPort Pro custom applications, any CP can be  
assigned as any function except that only CP1 can be assigned to RTS in RS232  
mode or TX Enable in RS485 Mode, and only CP3 can be assigned to CTS in RS232  
Mode. In XPort custom applications (RS232 mode), only CP1 can be assigned to  
RTS, only CP2 can be assigned to DTR, and only CP3 can be assigned to CTS.  
Note: NC=Not Connected to the XPort module. These pins can be assigned as  
needed using jumpers.

2 Demonstration Kit  
Configuration for Modem Control  
By default, on this demo board, the DCD and DSR signals are not routed to the XPort  
module. This makes it necessary to jumper the pins in JP6 in order to route the  
signals to the desired CPs on the XPort module.  
To be specific, if you wanted to route the serial port DCD signal to CP3 in order to  
take advantage of the modem control mode, you would place a jumper wire between  
JP6 pin 11 (the DSR signal from the serial port) to JP6 pin 10 (the CP3 pin from the  
XPort module).
