Comments

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.

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.

Direct connection of 3.3V and ground on MatchPort b/g Pro to 3.3V power and ground
planes of the target board is recommended in place of heavy trace routing to minimize
noises as well as voltage drops at the connection.

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.

MatchPort b/g Pro Integration Guide 10

There is an on board capacitor, 0.1uF to ground, at the RESETIN# to filter out transient
voltages. However, as always, 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

MatchPort b/g Pro Integration Guide 11

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.

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

MatchPort b/g Pro Integration Guide 12

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.

Wireless LED Connections

The W_LINKLED is driven by the Radio Module. It is active low. Recommended
connections on the target board are shown below.

Figure TBD. Recommended LED Connections

Output W_LINKLED 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 max.

2:Description and Specifications

If WLAN 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.

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).

Antenna

The MatchPort b/g Pro has been FCC certified with a 5dBi gain antenna for wireless

802.11b/g. It is for applications with antennas of equal gain or less. The following are two
of the recommended antennas with 2.15dBi gain and a link to their vendor. They are
available from Lantronix as well.

Serial Input/Output

The unit has two serial ports compatible with RS232 serial standards at data rates up to
230 Kbps. Serial Port 1 can also be configured as RS422/485, but Serial Port 2 cannot.
The serial I/O signals are 3.3V CMOS logic level. Serial signals can be connected to the
OEM CPU/UART or RS232/422/485 serial transceivers. For evaluation and prototype
work, it is convenient to have an external RS232 interface that can connect to the serial
port on a PC. The MatchPort Demo Board has RS232/422/485 transceivers to implement
this external interface. If desired, use the CPs to create a DTE or DCE-style interface
using any available CPs. To create these interfaces, connect the signals according to the
tables below.

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

ports, the selected transceiver(s) should have RS232/422/485 bus-pin ESD protection
(typically around 15 KV) either on-chip or by external diode arrays.

IO Configurable Pins (CPs)

There are up to seven CPs if no DTR or DCD is used on the serial ports. Any CP can be
configured as DTR or DCD as described above. CPs can be configured (see the User
Guide). All CPs have a pull-up.

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.

2:Description and Specifications

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.

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

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 hardwire 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.

shown in the following drawing:

Figure 2-14. PCB Layout (Top View)

2:Description and Specifications

Note: If a socket is used for product development purpose only, two 2-mm, 20-pin sockets

spaced 1.42" apart can be used (e.g., Samtec P/N SMM-120-02-S-S-TR).

u To optimize noise and cross-talk reduction, noise immunity, and impedance

matching on ETX+, ETX-, ERX+, ERX-, follow these guidelines when routing
traces on the target PCB:

- 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.

u 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.

u 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.
