Chapter 1:About the Module T he Digi Connect Wi-Wave module is an 802.11b/g WLAN communications module for use in embedded applications. The module is a single circuit card packaged in a PCI Express Mini Card form factor, and supports all the RF, analog, and digital circuitry necessary to implement WLAN functionality.
What’s on the module? What’s on the module? .................................................................................. U.FL connectors P2 P1 Edge connector, P3 Digi Connect WiWave module edge connector 10 The Digi Connect Wi-Wave module edge connector is a 52-pin connector whose pinout follows the standard PCI Express Mini Card edge connector pinout as stated in the PCI Express Mini Card Electromechanical Specification, Revision 1.
..... What’s on the module? Digi Connect WiWave module edge connector: Pinout The module edge connector is configured as shown (signal direction w.r.t Wi-Wave): Pin Type WLAN Mini Card signal Pin Type WLAN Mini Card signal 1 n/a No connect 2 In Vcc_3.
USB peripheral controller USB peripheral controller .................................................................................. The module uses a peripheral USB controller to interface to either a full speed or high speed USB 2.0 link. The link first tries to communicate to the host system board at the high speed USB rate (480 Mbps). If not successful, the link reverts to the full speed USB rate (12 Mbps). This link is used for all communication between the module and the host system board.
..... Voltage regulators Receiver Sensitivity and Transmit Output Power -71 dBm @ 54 Mbps -81 dBm @ 11 Mbps -88 dBm @ 6 Mbps -93 dBm @ 1 Mbps 13.8 dBm OFDM 17 dBm PSK/CCK Voltage regulators .................................................................................. The module takes in 3.3V±9% (3.00V to 3.60V) as its main input power. This power is filtered and used as a 3.3V supply to portions of the digital logic. This power also acts as input to dedicated on-board voltage regulators.
Power Power .................................................................................. The module requires only +3.3 VDC, 750 mA max. This power must be a wellregulated +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 36 for specifications. DISABLE signal 14 The module supports the active low W_DISABLE# signal (pin 20) as specified in the PCI Express Mini Card Electromechanical Specification.
Chapter 2:About the Development Board T he development board is designed for product evaluation and development purposes. In addition to the Digi Connect Wi-Wave connector, the development board provides several breakout connectors and interfaces. What’s on the development board ..................................................................................
ABOUT THE DEVELOPMENT BOARD What’s on the development board The development board Unpopulated components 16 There are components on the development board that are currently not populated. These components allow the development board to be used in other applications.
..... ABOUT THE DEVELOPMENT BOARD Digi Connect Wi-Wave module connector, J52 Digi Connect Wi-Wave module connector, J52 .................................................................................. Place the Digi Connect Wi-Wave module into the connector and support bracket, J52, on the development board. The Digi Connect Wi-Wave module connector is a 52-pin connector that conforms to the PCI Express Mini Card Electromechanical Specification, Rev. 1.
ABOUT THE DEVELOPMENT BOARD Digi Connect Wi-Wave module connector, J52 Note: 18 Signal direction w.r.t PCIe Mini Card. Pin Type Signal Pin Type Signal 1 n/a No connect 2 In Vcc_3.
..... ABOUT THE DEVELOPMENT BOARD LEDs LEDs .................................................................................. LEDs: DS3-DS7 LED DS1 The switching regulator is adjusted to output +3.3VDC ± 5% or better. LED DS1 lights up when the regulator outputs +3.3V power. See “Power supply” on page 21 for more information. LED DS2 LED DS2 lights up when the host system supplies power over the USB bus.
ABOUT THE DEVELOPMENT BOARD Switches and reset functionality 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.
..... ABOUT THE DEVELOPMENT BOARD Power supply 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.
ABOUT THE DEVELOPMENT BOARD JTAG Breakout Header, P20 cable to the development board. However, Digi recommends using the supplied AC wall adapter. JTAG Breakout Header, P20 .................................................................................. JTAG breakout header signal map 22 The development board provides a 20-pin JTAG header, P20. The pins are allocated as shown: Pin Type 1 Signal Pin Type Monitor pt +3.3V 2 Monitor pt +3.
..... ABOUT THE DEVELOPMENT BOARD USB peripheral interface, J4 USB peripheral interface, J4 .................................................................................. USB peripheral jack, J4 www.digiembedded.com The USB Type B connector, J4, is the primary communications interface to the development board. The USB bus is routed from the USB peripheral jack to the appropriate module connector pins.
ABOUT THE DEVELOPMENT BOARD Debug breakout header, P21 Debug breakout header, P21 .................................................................................. The debug breakout header’s primary purpose is to provide access to the W_DISABLE# signal. The W_DISABLE# signal is typically used as a hardware means to disable RF transmissions from the module without software intervention.
..... ABOUT THE DEVELOPMENT BOARD U.FL and RP-SMA connectors 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. U.FL and RP-SMA connectors .................................................................................. U.FL connectors The development board has two U.
ABOUT THE DEVELOPMENT BOARD U.FL and RP-SMA connectors on the development board and the other end of the cable to connector P2 on the Digi Connect Wi-Wave module. RP-SMA connectors RP-SMA Wi-Fi antennas are attached to the two RP-SMA connectors, J1 and J2. 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.
Chapter 3:Using the Antenna T he Digi Connect Wi-Wave development board supports two 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).
USING THE ANTENNA re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Connect Wi-Wave antenna configurations 28 The Digi Connect Wi-Wave 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's primary antenna.
..... USING THE ANTENNA General information 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.
