Disclaimer This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference, and (2)
this device must accept any interference received, including interference that may
cause undesired operation.
This device is intended only for OEM Integrators. The OEM integrator should be
aware of the following important issues.
Labeling of the End Product
The label on the end product incorporating the MatchPort b/g module must clearly
state that it contains an FCC-approved RF module. For example, “This product
contains an RF transmitter ID# (put FCC or IC module grant number here).” The
actual grant number is on the MatchPort b/g label.

MatchPort b/g Integration Guide 3
RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with Detachable
Antennas
This device has been designed to operate with the antennas listed in the Certificate,
and having a maximum gain of 5 dBi. Antennas not included in this list or having a
gain greater than 5 dBi are strictly prohibited for use with this device, unless system-
level FCC approval is gained. The required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not
more than that required for successful communication.
Integration Note
a) This module is authorized under limited module approval specified to mobile host
equipment. So, the antenna must be installed such that 20cm is maintained between
the antenna and users.
b) The transmitter module may not be co-located with any other transmitter or
antenna.
As long as the two conditions above are met, further transmitter testing will not be
required. However, the OEM integrator is still responsible for testing their end product
for any additional compliance requirements required with this module installed (for
example, digital device emission, PC peripheral requirements, etc.)
Note: In the event that these conditions cannot be met (for example certain
laptop configurations, general purpose PCMCIA or similar cards, or co-
location with another transmitter), then the FCC authorization is no longer
considered valid and the FCC ID cannot be used on the final product
(including the transmitter) and obtaining a separate FCC authorization.
Note: Changes or modifications to this device not explicitly approved by Lantronix will
void the user's authority to operate this device.

MatchPort b/g Integration Guide 7
2: Description and Specifications
The MatchPort b/g wireless embedded device server is a complete network-enabling
solution based on the IEEE 802.11b/g wireless standard, with 802.11i (PSK), WPA,
and WEP capabilities. MatchPort b/g allows Original Equipment Manufacturers
(OEMs) to add wireless connectivity to their products by incorporating it onto a circuit
board with minimal engineering.
The MatchPort b/g functions independently of a PC, providing an integrated solution
that combines a processor, memory, 802.11b/g transceiver, a 10/100 Mbps Ethernet
transceiver, and two high-speed serial ports into a single compact module. It includes
a wireless connection, an operating system, an embedded Web server, and a full
TCP/IP protocol stack. In addition, the MatchPort b/g sends email alerts and supports
numerous other network communication protocols, including ARP, UDP, TCP, ICMP,
Telnet, AutoIP, DHCP, HTTP and SNMP.
MatchPort b/g Overview
The MatchPort b/g contains Lantronix’s own DSTni controller with 256 Kbytes of
internal zero wait state SRAM and 16 Kbytes of boot ROM.
The MatchPort b/g also contains the following:
Two 3.3 volt, CMOS level, asynchronous serial interfaces (5 volt tolerant)
Support for RS-232 and RS-485 up to 921 Kbps
16 Mbit flash memory
26 (low), 48 (regular), 88 (high) MHz clock
802.11b/g interface
10/100 Mbps Ethernet transceiver (requires external magnetics and RJ45)
8 configurable pins
The MatchPort b/g requires +3.3-volt power and is designed to operate within a
temperature range of -40ºC to +70ºC.

Mating Connector
MatchPort can be soldered directly to the PCB using the footprint shown in Figure
2-10. If a socket is required, two 2 mm 20-pin sockets spaced 1.42" apart can be
used (e.g., Samtec P/N SMM-120-02-S-S-TR).
An antenna connection is made via the U.FL style connector on the MatchPort.
Lantronix offers two cable options, reverse-SMA to U.FL (P/N 500-180-R) or U.FL to
U.FL (P/N 500-181-R).

MatchPort b/g Integration Guide 10
Figure 2-3. U.FL to U.FL Cable (P/N 500-181-R)
Note: The antenna cable is included in the MatchPort b/g sample. For
production, it can be purchased from Lantronix or a cable supplier.
Serial Input/Output
The unit has two serial ports compatible with RS232 serial standards at data rates
up to 921 Kbps. The serial I/O signals are 3.3V CMOS logic level and pins are 5V
tolerant. Serial signals connect to the OEM CPU/UART. For evaluation and prototype
work, it is convenient to have an external RS-232 interface that can connect to the
serial port on a PC. The MatchPort Demo Board has RS-232/422/485 transceivers to
implement this external interface.
If desired, use the CPs to create a DTE or DCE-style interface using any three
available CPs. To create these interfaces, connect the signals according to Table 2-2
and Table 2-4.
Note: CPx, and CPy are any of the available CPs.

WLAN LED
MatchPort b/g
Output WLAN LED can be used to drive an external LED to monitor the activity of the
radio. The output is active when the receiver and or transmitter are on. The output is
active low and can drive an LED with 10mA. The LED shall be connected between
the output and 3.3V with a series resistor of 220 ohm.
Note: If you have questions or concerns, please contact Lantronix Technical
Support at [phone] (US only) or [phone].
If power management is disabled, and when the unit is associated with a network, the
receiver will always be on and thus any LED output, that indicates the receiver or
transmitter being on will be active continuously.

3: Demonstration Kit
The MatchPort b/g Demonstration Kit includes everything needed to begin to
integrate the MatchPort b/g into a given product design.
Contents of the Kit
The Demonstration Kit contains the following items:
MatchPort Demo Board
3.6V Power Supply
RS-232 cable, DB9F/F, null modem
Ethernet cable
Antenna
Note: You must purchase the MatchPort b/g sample separately for use with
this Demonstration Kit.
Demo Board Description
The MatchPort Demo Board provides a test platform for the Lantronix MatchPort b/g
device server. It supplies 3.3V power. The MatchPort demo board provides access to
all signals to and from the MatchPort b/g device server. The demo board has two
serial port interfaces (CON1 and CON2). The MatchPort b/g demo board also
includes an RJ45 connector for use with wired Ethernet.
Serial Interfaces
The MatchPort b/g serial interface is 3.3V logic level and typically connected to a
Universal Asynchronous Receiver/Transmitter (UART). For connection to an external
device, the demo board has RS-232/422/485 transceivers. CON1 and CON2 support
RS-232/485. Connect to a PC using a null-modem serial cable with 9-pin connectors
(F/F).
The table below lists the RS-232 signals and corresponding pins on the MatchPort
b/g. All signals are level-shifted by the RS-232 transceivers.
