Airborne DP550 Family Databook Quatech, Inc. 7.3 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 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. They are described in the SPI Commands section 0 below.
Airborne DP550 Family Databook 7.4 Quatech, Inc. 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 7.5 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.
Airborne DP550 Family Databook Quatech, 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.
Airborne DP550 Family Databook Quatech, 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.
Airborne DP550 Family Databook Quatech, Inc. 8.0 Antenna The unit supports antenna connections through two Hirose U.FL connectors (CN2 and CN3), located on the top surface of the device next to the RF shielding. The device supports both transmit and receive diversity. Antenna selection and diversity options are selectable through both the web and command line interfaces. Any antenna used with the system must be designed for operation within the 2.4GHz ISM band and specifically must support the 2.
Airborne DP550 Family Databook Quatech, Inc. used. There are many options for the antenna connector type, however if you wish to utilize the FCC/IOC modular approval the connector choice must comply with FCC regulations, these state a non-standard connector is required e.g. TNC/SMA are not allowed, RP-TNC/RP-SMA are allowed. 8.3 Host Chassis Mounted Antenna Host Chassis mounted antennas require no work on the host PCB. They utilize an antenna type called ‘flying lead’.
Airborne DP550 Family Databook Quatech, Inc. PCB Embedded – This approach embeds an antenna design into the host PCB. This approach is very common with add-in WiFi card (CF, PCMCIA, SDIO, etc.) as it requires no external connections and is the cheapest production approach. The lower production cost requires significant development cost and lack of performance and flexibility.
Airborne DP550 Family Databook Quatech, Inc. Locate the antenna where there is a minimum of obstruction between the antenna and the location of the Access Points. Typically Access Points are located in the ceiling or high on walls. Keep the main antenna’s polarization vertical, or in-line with the antenna of the Access Points. 802.11 systems utilize vertical polarization and aligning both transmit and receive antenna maximizes the link quality.
Airborne DP550 Family Databook Quatech, Inc. Link Margin provides a measure of all the parts of the RF path that impact the ability of two systems to communicate.
Airborne DP550 Family Databook 9.0 Quatech, Inc. RESET Function For correct operation of the on-board Power-on RESET (POR) and internal RESET controllers, the RESET pin on the WLNG-XX-DP550 family must obey the following timing and signal conditions.
