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.

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 dB. Antennas not included in this list or having a gain greater than 5 dB are strictly prohibited for use with this device. 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 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

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/g 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 -40ºC to +70ºC.
