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.

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).

connection to an additional RS485 transceiver, RTS
would be used to drive the transceiver TX enable.

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.

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).
