supply voltage information.

 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 pro module must clearly state that it contains an FCC-approved RF module. For example, "This product contains an RF transmitter FCC ID: R68MPBGPRO and IC: 3867A-MPBGPRO."

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 Pro Pinouts

There are two headers of 1x20, 2-mm pin spacing. The odd row header is designated as P1; pins are numbered 1 to 39. The even row header is designated as P2; pins are numbered 2 to 40.

Power and Ground

The MatchPort b/g Pro requires a regulated 3.3Vdc +/- 5% power input at P1.37 and ground at pin P1.39.

MatchPort b/g Pro Integration Guide 9

Note: To minimize noises as well as voltage drops at the connection, We recommend

direct connection of 3.3V and ground on the MatchPort b/g Pro to 3.3V power and ground planes of the target board in place of heavy trace routing.

Reset

The MatchPort b/g Pro reset pin RESETIN# is an input-only pin and connects to an 811type reset IC. This input is for a pushbutton switch type manual reset. If no external reset control is desired, leave this pin floating.

Minimum reset pulse is 2 ms. There is an on board capacitor, 0.1uF to ground, at the RESETIN# to filter out transient

voltages. However, it is a good practice to have RESETIN# trace on the target board as short as possible to avoid reset occurrences when transient voltages such as those caused by ESD are present.

Ethernet Connections

The MatchPort b/g Pro provides Ethernet interface transmit ETX and receive data ERX connections from a PHY device. Thus, before presenting signals to the outside world using an RJ45 jack, a 1:1 Ethernet Magnetics is needed to interface and to isolate the unit. A recommended connection diagram to an RJ45 jack with integrated 1:1 Ethernet magnetics is shown below.

2: Description and Specifications

Figure 2-2. Connection Diagram to an RJ45 Jack

We recommend a low capacitance TVS diode array such as a Semtech SRV05-4 at ETX+, ETX-, ERX+, ERX- if frequent transient voltages are present.

MatchPort b/g Pro Integration Guide 10

Ethernet LED Connections

The E_LINKLED and E_ACTLED signals are driven by the PHY. They are active low. Recommended connections on the target board are shown below.

Figure 2-3. Recommended LED Connections

Warning: The MatchPort b/g Pro has two 4.7K pull-ups on the E_LINKLED

and E_ACTLED signals to set up the PHY’s LED Indicator Mode as Ethernet Link and Activities at Power On Reset (POR). Do not connect these two signals with any pull-down resistors as they may corrupt the logic level on these two signals at POR, causing undesired operation.

2: Description and Specifications

Wireless LED Connections

The W_LINKLED is driven by the Radio Module. Active low. Open drain. 10mA max. Recommended connections on the target board are shown below.

The LED is activated when either the receiver or transmitter is active. With WLAN power management disabled, the receiver is always active when the transmitter is not and thus the LED always on when WLAN is the enabled interf ac e. With WLAN power management enabled, receiver and transmitter are turned on selectively and thus the LED flickers.

Figure 2-4. Recommended LED Connections

Antenna Mating Connector

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 2-10. Separate RS422 Transceivers for 2-Wire and 4-Wire Setups

To protect the MatchPort b/g Pro and circuitry on the target board against ESD at serial ports, the selected transceiver(s) should have RS232/422/485 bus-pin ESD protection (typically around 15 KV) either on-chip or b y extern al diod e arrays.

IO Configurable Pins (CP s )

There are up to seven CPs if no DTR or DCD is used on the serial ports. All CPs have internal pull-up resistors, but the value differs. See table.

CPs can be configured for special functions, like DTR, DCD, RS232/RS485 selection or as general purpose Input or Output (pollable/controllable via CLI or Web Manager). For more information see the User Guide.

MatchPort b/g Pro Integration Guide 15

BOOTP_EN#

The BOOTP_EN# pin performs two functions simultaneously. It drives an optional external diagnostics LED to indicate the status of the bootloader. It also serves as input to enable booting from the network when no valid FW image is found in FLASH.

BOOTP enable

Holding BOOTP_EN# low (via switch or jumper) during and up to 10 seconds after a reset allows booting the device with a FW image on a TFTP server only in case no valid image is present on FLASH.

The MatchPort b/g Pro will issue a BOOTP request to acquire an IP address for itself, the IP address of a TFTP server, and the filename of the FW image on the TFTP server. Then it will fetch that file via TFTP, verify, and execute it.

Diagnostics LED

After supplying power to the unit or pressing and releasing the reset button, the diagnostics LED turns on and stays on while the bootloader is running and does not encounter any errors. After the bootloader loads firmware from serial, network or FLASH, it turns off the LED right before handing over execution.

In case an error occurs during the bootloader operation, it will flash the LED. The pattern will be pause, X * long flashes, Y * short flashes, pause, X long flashes, etc.

2: Description and Specifications

X is the first digit of the error number and Y the second. Following are the currently implemented errors:

INVALID_BOOTLOADER_CHECKSUM 11 NO_FLASH_IMAGE_FOUND 12 BAD_FLASH_IMAGE_FOUND 13 BAD_COMMAND_PARAMETER 14 NO_BOOTP_RESPONSE 15 BAD_BOOTP_RESPONSE 16 NO_BOOTP_TFTP_IMAGE 17 RECEPTION_TIMEOUT 18 RECEPTION_OVERRUN 19 IMAGE_OVERSIZE 21 BAD_IMAGE_CHECKSUM 22 BAD_IMAGE_DESTINATION 23 INTERNAL_CODING_PROBLEM 24

Pin Connection Options

The circuit below is an example on how to correctly connect a switch (or permanent jumper) and an LED to the BOOTP_EN# pin. The customer has the option of implementing either the switch/resistor or the driver/LED or both or none.

The switch can be replaced by a jumper or hardwire. Having the har d wire in place means that if the firmware image in FLASH becomes corrupt, the MatchPort b/g Pro will automatically send out BOOTP requests over the network. This could be a security risk. The switch or jumper allows BOOTP requests to be sent only after manual intervention.

If no switch/jumper/hardwire is installed, network recovery is only possible by issuing a!NL command over the serial port.

− Route (ETX+, ETX-) pair as close to each other as possible, and far away

from ERX+, ERX- and other signals

− Route (ERX+, ERX-) pair as close to each other as possible, and far away

from ETX+, ETX- and other signals

− Set up PCB routing properties on each pair (ETX+, ETX-) and (ERX+, ERX-)

to achieve 100-ohm impedance.

− For EMI purposes, connect the metal housing (shield) of the RJ45 jack to

Power Ground or Earth Ground and do not allow floating. If power ground and earth ground are to be separated, add ceramic

capacitors in the range of 1000 pF to 0.1 uF in a stitching pattern between the two grounds to provide low impedance paths at high frequencies. The voltage rating on the ceramic capacitors should be much higher than the required isolation voltage between the two grounds.

 Connect 3.3V and ground on the MatchPort b/g Pro directly to 3.3V power and

ground planes of the target board in place of heavy trace routing. This will minimize noises as well as voltage drops due to the trace.

 Make the RESETIN# trace on the target board as short as possible to avoid reset

occurrences when transient voltages such as those caused by ESD are present.

Note: CP allocation in the tables above is the most straightforward for this

specific board. However any CP can be assigned to any function. To reflect actual CP use in the eventual product (in case different), jumpers can be replaced with short wires to allow interchanging of connections.

Table 3-7. Demo Board JP5 Jumper Configuration

Note: Jumper can be replaced with short wire to allow use of a current clamp or <50

milliohm resistor to allow use of voltmeter for current measurements.

If using CPs for any combination of the demo board configurations above, please use the appropriate CP function selection as shown in Table 3-3 to Table 3-7.

If assigning a CP for any function other than the serial port, remove the jumper for the associated CP pin from JP7 to avoid conflict with the serial port function.
