Linux OS sample (Lantronix PN: XPP100300S-01R).

 For evaluation of XPort Cobos OS based turnkey application, one would require

 The XPort Pro Linux SDK (Lantronix PN: XPPDK1000-LNX-01) provides

 The XPort Pro Evolution SDK (Lantronix PN: XPPDK1000-EVO-01) provides

 A separate USB BDM Debug Probe (Lantronix PN: 930-060-R) is available for

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.

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 RS-232 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 RS-232 signals and corresponding pins on the demo
board. All signals are level-shifted by the transceivers.

Function

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 on ly CP1 can be as s igned to RTS in RS-232
mode or TX Enable in RS485 Mode, and only CP3 can be assigned to CTS in RS­232 Mode. In XPort custom applications (RS-232 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.

XPort Universal Demo Board User Guide 8

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).
