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 Digi Connect Wi-Wave 802.11 b/g edge connector (pin 22), as well as to the debug breakout header for monitoring.Alternative methods to trigger RESET#In addition to supply voltage monitoring, reset logic can be triggered in another way:Manually push SW1, a pushbutton reset switch on the development board

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. Ground 9-30VDC +/- 5%

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). Single antenna configuration: Connect one end of the U.FL cable to connector P1 on the development board and the other end of the cable to connector X5 on the Digi Connect Wi-Wave 802.11 b/g module. Dual antenna configuration: In addition to the connections outlined in the Single antenna configuration, connect one end of the second U.FL cable to connector P2 on the development board and the other end of the cable to connector X4 on the Digi Connect Wi-Wave 802.11 b/g module.

Single antenna configuration: Attach an RP-SMA antenna to RP-SMA connector J1.Dual antenna configuration: Attach RP-SMA antennas to both RP-SMA connectors J1 and J2.For more information For information about the antenna(s), see Chapter 3, “Using the Antenna.”
25Chapter 3:Using the AntennaThe Digi Connect Wi-Wave 802.11 b/g development board supports one type of antenna: 29000146 ANT, WHIP 2.4 GHz DipoleAttach 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 IntegrationThe 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.

B 2/2010Connect Wi-Wave 802.11 b/g antenna configurationsThe 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 informationThe 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.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Cable Specification: U.FL/W.FL to RP-SMAAttributes Note:Dimensions are provided for reference purposes only.
