Power
The module requires only +3.3 VDC, 750 mA max. This power must be a well-
regulated +3.3V supply due to limited supply filtering in the module. The digital
inputs and outputs are 3.3V CMOS compatible. See “Power requirements” on
page 31 for specifications.
DISABLE signal The module supports the active low W_DISABLE# signal (pin 20) as specified in the PCI
Express Mini Card Electromechanical Specification. This signal not only disables the
power supplies to the radio portion of the module, it also powers down additional
portions of the module to reduce power consumption to a minimum.

Power supply
The development board provides a 3.3VDC switching power supply. Either a bench
power supply or an AC wall adapter supplies input power to the development board.
The required input voltage range is 9–30VDC.
Input power jack,
J3 The input power jack, J3, is a barrel connector that accepts 9-30 VDC. The power
jack is labeled J3 on the development board. This figure schematically represents
the power jack’s polarity:
Input power
supply The output current of this regulator is limited to 2.4 amps and the Digi Connect Wi-
Wave 802.11 b/g module draws no more than .750 amps. Using these values as a
guideline, and using an 80% efficiency for the switching regulator, the input power
supply should be rated to provide at least 3 watts of power.
Important:
The development board can use USB power as the power source for the
3.3V regulator. This is accomplished by simply connecting the USB
cable to the development board. However, Digi recommends using the
supplied AC wall adapter.

W_DISABLE#
signal The active low W_DISABLE# signal is on pin 20 of the debug breakout header. GND
signals are positioned adjacent to the W_DISABLE# signal on pins 18 and 19. To
assert the W_DISABLE# signal to the module, place a jumper between either pins 18
and 20 or pins 19 and 20.
As an alternative, you can drive this pin with a low voltage TTL or CMOS driver.
When asserted, W_DISABLE# lights the DISABLE LED, DS3.

Chapter 3:Using the Antenna
The Digi Connect Wi-Wave 802.11 b/g development board supports one type of
antenna:
29000146 ANT, WHIP 2.4 GHz Dipole
Attach the U.FL-to-U.FL cables, provided in the development kit, to both the
module and the development board. There are two cables included; whether you
use one cable or both depends on how you set up your antenna(s).
Be sure that the antenna you use complies with the regulatory requirements of your
region. In North America, for example, you can operate only with antennas
approved by Digi International, Inc., or antennas matching the specifications of
Digi-approved antennas.
Necessary
Conditions for
Integration
The following conditions are necessary for integration:
The antenna must be installed such that 20 cm is maintained between the
antenna and users for all installations.
The transmitter module may not be co-located with any other transmitter or
antenna.
The Module is approved using the FCC “unlicensed modular transmitter
approval” method; therefore, the module must be used with the originally-
approved antennas only.
As long as you meet these three conditions, further transmitter testing will not
be required. However, you are still responsible for testing your end-product
for any additional compliance requirements associated with this module
installation (e.g., digital device emissions, PC peripheral requirements, etc.).
Note: In the event that any of these conditions cannot be met (e.g., portable
configurations, co-location with another transmitter, or use of a different antenna),
then the FCC authorization is no longer considered valid, and you are unable to use
the FCC ID on the final product. In these circumstances, you will be responsible for
re-evaluating the end product (including the transmitter) and obtaining a separate
FCC authorization.

configurations
The Digi Connect Wi-Wave 802.11 b/g can transmit data or receive data, but not at
the same time.
Note: If only one antenna is used, it must be connected to Wi-Fi RP-SMA antenna
connector J1. This is the Digi Connect Wi-Wave 802.11 b/g’s primary antenna.

General information
The module uses the same antennas to transmit and receive the 802.11b/g RF
signal. An antenna switch is required to isolate the transmit signal from the receive
signal. The antenna switch works by alternately connecting the antennas to either
the transceiver transmit output or the transceiver receive input. To support this
antenna sharing scheme, the module operates in half-duplex mode; receive and
transmit operations do not occur at the same time.
Antenna switch The antenna switch is a digitally controlled 2.4 GHz, 50 ohm, multi-function solid
state switch, controlled by software.
The switch can handle >28dBm of signal on the transmit port. The insertion loss of
the antenna switch is <0.5dB and the receive to transmit port isolation is >23dB.
