APPN-TT551 Databook B&B Electronics, Inc. 5.1 AC Electrical Characteristics – Transmitter Transmit power is automatically managed by the device for minimum power consumption. The MAXIMUM transmit power at the RF connector is typically +15dBm ± 2 dB for all bands (b/g/n) and rates. 5.2 Performance/Range The following table illustrates the typical data rates, performance and range that the device is capable of providing using an omni directional antenna.
APPN-TT551 Databook 6.0 B&B Electronics, Inc. SPI Interface The following section details the SPI interface specification for both hardware timing and SPI protocol. The device is a SPI slave and requires a compatible SPI master for operation. 6.1 Pin-out When the SPI interface is enabled, through the CLI or web interface, the following pins are assigned for communication.
APPN-TT551 Databook B&B Electronics, Inc. 6.2 SPI AC Characteristics The following specification identifies the required hardware timing to successfully implement a SPI interface with the Airborne Device Server module. Table 12 - SPI AC Timings Symbol Parameter Min fMAX Maximum Clock Frequency tCS SPI Select Low to Clock Rising Edge 100 ns tCH Clock High 62.5 ns tCL Clock Low 62.5 ns tDA Clock High to Data Out Max Units 8.
APPN-TT551 Databook 6.3 B&B Electronics, Inc. SPI Protocol A SPI message is composed of a 4 byte header followed by 0 or more bytes of data. The header data is full-duplex. That is, the TX message header is sent to the Airborne Device Server module by the host at the same time that the RX message header is sent to the host from the Airborne Device Server. The TX message header consists of a Command (CMD) byte, followed by three Parameter (PARM) bytes.
APPN-TT551 Databook B&B Electronics, Inc. 6.4 SPI Modes The Airborne device supports the following four SPI modes. These are selectable through the command line or web interfaces. The default mode is zero (0). Table 15 - SPI Modes 6.5 SPI Mode Clock Idle Clocking Edge 0 Low High-Low (trailing edge) 1 Low Low-High (leading edge) 2 High Low-High (trailing edge) 3 High High-Low (leading edge) SPI Commands The following commands are available for use in the CMD message header.
APPN-TT551 Databook B&B Electronics, Inc. Command (Hex) Name Description 0x10 INTENA The INTENA command will configure the specific interrupts to be enabled from the module. For this command, the PARM1 field will define the interrupts to be enabled. The definition of the PARM1 field for this command is a bit-mask and is formatted as follows: Bit 7 Interrupt Sense – Determines the asserted state of the interrupt pin.
APPN-TT551 Databook B&B Electronics, Inc. Command (Hex) Name 0x40 TXDATA Description The TXDATA command is used to send data to the module to be interpreted as commands if the module is in CLI mode, or to be transmitted on the wireless link if the module has an active data connection established. The host may send at most the number of bytes indicated by the TX Buffer Available field in the RX Message Header. The actual number of bytes sent by the host is determined by the 16 bit value in PARM2.
APPN-TT551 Databook 7.0 B&B Electronics, Inc. Antenna The unit supports antenna connections through a Hirose U.FL connector (ANT1). It is located on the top surface of the device next to the RF shielding. Any antenna used with the system must be designed for operation within: the 2.4GHz ISM band and must specifically support 2.412GHz to 2.482GHz for 802.11b/g operation. They are required to have a VSWR of 2:1 maximum referenced to a 50Ω system impedance. 7.
APPN-TT551 Databook B&B Electronics, Inc. provides a bulkhead mounted antenna connector and the other provides a bulk head mounted antenna. The type you choose will be determined by the application. A flying lead system connects a U.FL coaxial lead to the radio’s U.FL connector. The other end of the coax is attached to either a bulkhead mounted antenna connector or directly to an antenna that has an integrated bulkhead mount.
APPN-TT551 Databook B&B Electronics, Inc. flying lead antennas tend to provide more performance and flexibility than other approaches, since the location of the antenna is not determined by the host PCB design. The assembly of a system using embedded flying lead antennas may be slightly more complex, as the antenna is not necessarily mounted on the host PCBA. 7.5 Antenna Location The importance of location cannot be over stressed.
APPN-TT551 Databook B&B Electronics, Inc. a given link rate drops below a predefined limit the radio will drop to the next lowest link rate and try to communicate at that rate. The reverse is also true. If the radio observes good link quality at one rate it will try to move up to the next rate to see if communication can still be sustained. Note that for a given position the link quality improves as the link rate is reduced.
APPN-TT551 Databook 8.0 B&B Electronics, Inc. RESET Function For correct operation of the on-board Power-on RESET (POR) and internal RESET controllers, the RESET pin on the module must obey the following timing and signal conditions.
