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).

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.
