Switches and reset functionality
Voltage monitor The development board provides a power supply voltage monitor and reset
generator. When the +3.3V regulated supply voltage drops below 2.93V, the reset
signal — RESET# — is asserted for a minimum of 140 msec. This signal is connected
to the Connect Wi-Wave edge connector (pin 22), as well as to the signal breakout
header for monitoring.
Alternative
methods to trigger
RESET#
In addition to supply voltage monitoring, reset logic can be triggered in two other
ways. The RESET# logic is asserted when you do one of these actions:
Manually push SW1, a pushbutton reset switch on the development board
Pull low pin 15 on the JTAG breakout header, P200

The required input voltage range is 9–30VDC.
Input power jack,
J1
The input power jack, J1, is a barrel connector that accepts 9-30 VDC. The power
jack is labeled J1 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 3 amps and the Connect Wi-Wave
module draws no more than 1.5 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 6 watts of power.
Important:

U.FL and RP-SMA connectors
U.FL connectors The development board has two U.FL connectors that pair with two RP-SMA
connectors. WiFi antenna 1 (P11) pairs with RP-SMA connector J11; WiFi antenna 2
(P12) pairs with RP-SMA connector J12.
???U.FL cables The development kit includes two U.FL-to-U.FL cables that can be used to connect
the module and development board. The number of cables used depends on
whether one antenna is used to transmit and receive or two antennas are used
(diversity receive).

Using the Antenna
The Digi Connect Wi-Wave development board supports three types of antennas:
29000095 ANT, WHIP 2.4-2.5 GHz Dipole (2.0000)
29000146 ANT, WHIP 2.4 GHz Dipole 5 dBi (2.0000)
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 (for example
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.
USING THE ANTENNA
28 Connect Wi-Wave Hardware Reference, Rev B 9/2007
Connect
Wi-Wave antenna
configurations
The Connect Wi-Wave can transmit data or receive data, but not at the same time.
Software controls the transmit/receive functionality as well as the antenna switch.
You have the option of using two antennas (required for diversity receive) or one
antenna to transmit and receive data.
Using two antennas: The Connect Wi-Wave transmits on one antenna and
receives on the other antenna (at separate times) without changing the
antenna switch. Use both cables.
Using one antenna: The Connect Wi-Wave transmits on one antenna, software
toggles the antenna switch, then the Connect Wi-Wave receives on the same
antenna. Use only one cable, which can be connected to either U.FL connector
on the module and on the development board.
U.FL cable and
RP-SMA
connection
Use these connection steps with the RP-SMA antennas: 29000095 — 2.4-2.5 GHz
Dipole and 29000146 — 2.4 GHz Dipole 5.5 dBi:
1Attach one end of the cable(s) to the U.FL connector(s) (P1, P2) on the Connect
Wi-Wave module.
2Attach the other end of the cable(s) to the U.FL connector(s) (P11, P12) on the
development board.
3Attach the RP-SMA antenna to the appropriate RP-SMA connector (J11, J12) on
the development board. If you are using only one cable/connection, be sure you
attach the RP-SMA antenna to the correct connector:
–If the cable is connected to U.FL connector P11, or WiFi antenna 1, attach
the RP-SMA antenna to J11.
–If the cable is connected to U.FL connector P12, or WiFi antenna 2, attach
the RP-SMA antenna to J12.

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 PA 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 receive port can be switched between antenna 1 or antenna 2.
The transmit port can be switched between antenna 1 or antenna 2.
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.
