2: Description and Specifications
The XPort AR embedded device server is a complete network-enabling solution enclosed
within an RJ45 package. This miniature device server empowers original equipment
manufacturers (OEMs) to quickly and easily go to market with networking and web page
serving capabilities built into their products.
The XPort AR
The XPort AR contains Lantronix’s own DSTni controller, with 256 Kbytes of SRAM,
16 Kbytes of boot ROM, and integrated AMD 10/100 PHY.
The XPort AR also contains the following:
New powerful operating system with additional new features.
Two full serial ports with all hardware handshaking signals (or three serial ports without
handshaking signals).
13 pins are configurable as general purpose I/O.
Supports fully compliant Power over Ethernet (PoE) designs by using PoE compliant
magnetics and passing through both the used and unused pairs.
Memory: 4 MB Flash and 1.25 MB RAM.
3.3-volt serial interface.
All I/O pins are 5V tolerant.
Ethernet magnetics.
Power supply filters.
Reset circuit.
+1.8V regulator.
Ethernet LEDs.
The XPort AR requires +3.3-volt power and is designed to operate over an industrial
temperature range (see technical data).

XPort AR Block Diagram
The following drawing is a block diagram of the XPort AR showing the relationships of the
components.
Figure 2-2. XPort AR Block Diagram
PCB Interface
Standard Pins (Evaluation Board XP300200K-01)
The XPort AR has 26 electrical pins. There are 20 pins that form two rows of ten. These 20
pins form the standard interface between the XPort AR and the circuit in which it is installed.
These include dedicated serial as well as 11 programmable I/O pins (Configurable Pins, or
CPs). The other group of six pins is for PoE.
The standard signals are 3.3V CMOS logic level but are 5V tolerant. These signals are
typically connected to internal devices, such as a relays, sensors, or UARTs.For prototype
and evaluation work or applications where an external RS-232 interface is required,RS-232
transceivers are available on the XPort AR evaluation board. Optionally, disconnect them
using the jumpers provided if they are not needed.
Note: Typically, after booting up CP pins are in an unstable state for a few seconds.
However, the state of the CP pins in the XPort-AR is initially high-impedance, suitable
for an input. To use a CP pin as an output, the pin may be biased high or low with a
resistor to +V or ground so it will be "defined" as either 1 or 0 during this initial time.

PoE Pins
XPort AR is PoE-ready; it allows a fully compliant PoE circuit to be implemented that uses the
Ethernet signals entering the XPort AR’s RJ-45 jack. When the XPort AR’s RJ-45 jack is
connected to a PoE compliant switch, pins 21, 22, 25, and 26 pass through the necessary
Ethernet signals to allow a PoE powered-device circuit to negotiate and receive power from
the switch.

Reset
The XPort AR reset pin is an input-only pin and connects to an 811-type reset IC. Internal to
the 811 is a 20k pull-up. This is the only influence the XPort AR has on the reset pin. This
input is intended for a push-button switch type manual reset. If no external reset control is
desired, leave this pin floating.

Recommended PCB Layout
The hole pattern and mounting dimensions for the XPort AR are shown in the following
illustration. For proper heat dissipation, it is recommended that the PCB have approximately
1 square inch of copper attached to the shield tabs. The shield tabs are an important source
of heat sinking for the device.
Figure 2-7. PCB Layout (Top View)
XPort Compatibility
The XPort AR is designed for the PCB layout to accommodate either an XPort AR or the
original Lantronix XPort. To accomplish this, a few extra holes are required. The hole
pattern and mounting dimensions for this combination XPort/XPort AR footprint are shown in
the following drawing:

XPort AR
The XPort AR is placed in the upper left corner of the evaluation board and is referenced as
J1.
Note: The footprint used for J1 on the evaluation board is compatible with both the
XPort AR and the original Lantronix XPort.
Power Switch
The two positions of the power switch are On and Off/PoE. In the On position, the evaluation
board gets its power from the 3.3 VDC input jack. In the Off/PoE position, the evaluation
board uses 3.3 VDC from the PoE socket S1 (if a circuit is attached that makes it available).
This provides a convenient On/Off switch in either case.
Reset Switch
The reset switch grounds the reset pin on the XPort AR. The XPort AR reset pin is an input-
only pin and connects to an 811-type reset IC. Internal to the 811 is a 20k pull-up and is the
only influence the XPort AR has on the reset pin.
Headers
The headers provide access to all of the XPort AR signals, as well as to circuits for I/O control
and monitoring.
JP1: Signal Access Header
This header provides access to each XPort AR signal.Use these pins to monitor activity with
an oscilloscope or to jumper to one of the four monitoring LEDs. When a CP is configured as
an input, it can be connected with a jumper to GND, a pull-up, or switch with pull-up and
switchable ground contact.
Note: Typically, after booting up CP pins are in an unstable state for a few seconds.
However, the state of the CP pins in the XPort-AR is initially high-impedance, suitable
for an input. To use a CP pin as an output, the pin may be biased high or low with a
resistor to +V or ground so it will be "defined" as either 1 or 0 during this initial time.

JP2: LED Header
This header provides access to each of the monitoring LEDs.These pins can be connected
with a jumper wire to any of the JP1 pins to monitor the signal level with the corresponding
LED. When a high is present, the LED illuminates. Test LEDs by using a jumper to any of
the JP4 pull-up pins. Each LED has a unique color to facilitate identifying the LEDs that are
on.

JP2 Pin # Connects To:
1 LED1 – green
2 LED2 – yellow

JP3: Input Switch Header
This header provides access to each of the two input control switches.These pins can be
connected with a jumper wire to any of the JP1 pins to control the signal level with the
corresponding switch. When a switch is in the center position, it is off. This allows a 1K pull-
up resistor to create a high on the corresponding pin. When a switch is turned on, it connects
the corresponding pin to ground. Each switch has a latched-on down position and a
momentary-on up position
