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 end product to integrate this module has to be clearly identified on the label that

this end product contains an FCC approved RF module. The format of such

statement could be "Contains Transmitter with FCC ID: R68WIPORTG" or similar.

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 2 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 can not 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 can not 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.

WiPort™IntegrationGuide 6

About the Integration Guide

This guide provides the information needed to integrate the WiPort device server

within another product. The intended audiences are the engineers responsible for

integrating the WiPort into their product.

Additional Documentation

The following guides are available on the product CD and the Lantronix Web site

(www.lantronix.com)

WiPort™ Development Kit

Quick Start Guide

Briefly explains the basics to get the WiPort up

and running.

WiPort™ User Guide Provides information needed to configure, use,

and update the WiPort firmware.

WiPort™IntegrationGuide 7

The WiPort wireless embedded device server is a complete network-enabling

solution based on the IEEE 802.11b/g wireless standard, with WPA and WEP

capabilities. WiPort allows Original Equipment Manufacturers (OEMs) to add

wireless connectivity to their products by incorporating it onto a circuit board with

minimal engineering.

The WiPort functions independently of a PC, providing an integrated solution that

combines a processor, memory, 802.11b/g transceiver and dual 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

WiPort sends email alerts and supports numerous other network communication

protocols, including ARP, UDP, TCP, ICMP, Telnet, AutoIP, DHCP, HTTP and

SNMP.

WiPort Overview

The WiPort contains Lantronix’s own DSTni controller with 256 Kbytes of internal

zero wait state SRAM, 16 Kbytes of boot ROM, and integrated 10/100 PHY.

The WiPort also contains the following:

 Two 3.3-volt v24 serial interfaces (5V tolerant)

 Up to 921600 Baud

 16 or 32Mbit flash memory (with optional additional 8Mbit SRAM)

 88 MHz clock

 802.11b interface

 11 configurable pins

 10/100 Ethernet interface

The WiPort requires +3.3-volt power and is designed to operate within a temperature

range of -30ºC to +70ºC.

Mating Connector

Table 2-2. Mating Connectors

Mating Connector Description

Recommended: Samtec FTMH-120-03-F-DV-ES (shrouded

header)

Alternative: Samtec FTMH-120-03-F-DV (not shrouded)

Alternative: Oupiin 2411-2X20GDN/017 (not shrouded)

The mating connector is

a 1mm micro header,

40 pins,

2 x 20.

Serial Input/Output

The unit has two serial ports compatible with V24 serial standards at data rates up to

921Kbps. The serial I/O signals are 3.3V CMOS logic level and pins are 5V tolerant.

Serial signals connect to an internal device, such as a 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 WiPort Evaluation Board has one RS-232

and one RS-232/422/485 transceiver (level shifters) to implement this external

interface (only the WiPort 485 supports the RS-422/485 interface).

If desired, use the CPs to create a DTE or DCE-style interface using any 3 available

CPs. To create these interfaces, connect the signals according to Table 2-3 and

Table 2-4.

Note: CPx, CPy, and CPz are any of the available CPs.
