BLIZZARD-868

BLIZZARD USB / RS232 Radio MODEM Features: • Plug ’n’ Play RF Modem • Direct Cable Replacement • Range 1KM • Host Data Rates up to 38,400 Baud • RF Data Rates to 115Kbps • Waterproof IP68 Enclosure • 8 User Selectable Channels • CE Compliant for Licence Free Use • FCC Approved for Use in USA • 100mW Transmit Power (+20dBm) Intended Use • Receiver Sensitivity –116dBm • USB/RS232 Cable Replacement • M2M Communications • Remote Networking Description: The BLIZZARD radio modem is a simple to use and very versatile. It can operate as a PC or M2M, one to one cable replacement link, multiple master/slave arrangements or broadcast modes. Operation Modes One-to-One operation: for point to point cable replacement. Broadcast Mode: where a single master BLIZZARD addresses many other BLIZZARDS concurrently. (Using many BLIZZARD modem set to the same address). One-to-Many: a network consisting a master BLIZZARD and many slave BLIZZARD (the slaves all have the same address). Many-to-One: where the transmitters all send to a single receiver address. Because each Blizzard modem can contain a unique address, multiple Blizzard modem networks can co-exist in the same area. Ordering Information Part No Description BLIZZARD-868 Radio Modem 868MHz PSU-12V1AIN-IP Power Supply 12V 1A IP67 DS-BLIZZARD-3 Blizzard Radio Modem Overview - What’s in the box? Supplied with the Blizzard modem: 1. Modem PCB assembly 2. IP68 enclosure with sealing gaskets and cable gland 3. RS232 cable lead 4. USB cable lead 5. Screw fit M4 thread antenna. NOTE: In order to make use of the IP68 waterproof enclosure then it may be necessary to cut off and replace the connector on the end of the cable lead because it is not possible to pass through the cable gland. Alternatively - use the USB lead. NOTE: It is not possible to connect an external antenna to the BLIZZARD. The schematic diagram of the PCB assembly showing connections required to interface the on board connectors is provided later in this datasheet. NOTES on optimising range In order to obtain greatest range ensure the following: 1. Use an external 12Vdc supply (i.e. don't rely on the USB power cable) 2. Use the slowest RF data rate setting 3. Position the BLIZZARD high off the ground and in free space. Blizzard Radio Modem Inside the Blizzard Modem Antenna Connection Config Links - Sleep Mode - Address Write - Baud Rate Select RS232 / USB Selection Links PCB Dimensions 90 X 55mm RS232 USB Power In USB / D links (LK2,3,4,5) For USB connect all links from centre to ’USB’ side. For RS232 connect all links from centre to ‘RS232’ side. Power When using USB host connection there is no requirement to provide external power although the range will be improved with an external 12V source. Serial data format Baud rate: Defined by DR1 and DR2 Pins, 8 data bits, No parity, 1 stop bits. Flow control: Hardware CTS / RTS. CTS, RTS Clear-to-Send and Request-to-Send are standard data flow control used in RS232 systems. Note: If you do not intend to use handshaking, it is possible to tie the RTS pin to GND and use the modules without. In this configuration the BLIZZARD modem module will send all data in its buffer after a 10ms timeout. Up to 57bytes can be buffered before data is lost. A minimum of 15ms should be al-lowed before new data is sent to the module after each packet. This is not a recommended method of operation. Tx / Rx LED The LED’s operates whenever there is RF activity. DR1 - DR2 These inputs define the host interface baud rate. They are read when RESET pin goes high. Tip: It is good practice to operate the host interface at half the speed of the RF data rate (set by Register R5).

Note: Because each BLIZZARD modem module can be given a unique address, multiple BLIZZARD networks can co-exist in the same area. This type of operation requires clear timing between transmissions or corruption of packets can occur. Addressing Networks Each BLIZZARD modem module has a generic pre-configured default address (7F7F7F). This can be modified during configuration. When data received via RF it is examined and the address header embedded with-in it is compared with its address. Only data received with matching address will be processed and out-put to the host, all other data will be discarded. When sending data, the BLIZZARD modem module has a default destination address set to 7F7F7F, this can be user configured. By setting the two addresses appropriately the above network types can be easily achieved. Operating Modes Configuration Mode: In configuration mode the BLIZZARD modem module can receive commands to set internal registers to define its eventual operation. In this mode the BLIZZARD modem module is ‘Offline’ and cannot send or receive RF data. Normal Operation: The BLIZZARD modem module is ’Online’ automatically transmitting and receiving data from its serial interface across its RF network. Acknowledge Secure Mode: In this mode each time a BLIZZARD modem module transmits an RF packet, an additional ‘packet ID’ is added. This ID is a rolling verification counter to receiving BLIZZARD modem modules. Any correctly addressed receiving BLIZZARD modem module replies with an RF acknowledgment also containing the ‘packet ID’. If the transmitting BLIZZARD fails to receive the expected acknowledgement it will transmit the packet again (up to 10 times). Host Terminal Software Any Terminal emulation program can interface the Blizzard modem, one we have found to be easy to use and powerful is ‘Terminal’ - This can be downloaded from: https://sites.google.com/site/terminalbpp/ Ping-Pong Mode This test mode is built into the modem to enable two modems to pin pong signals to each other and report the (RSSI) on the originating modem. To initiate ping pong; 1. 2. 3. 4. 5. 6. Connect modems to host PC USB ports Run your terminal emulation program Determine the USB port modem is connected to (from device manager under computer properties) Set the terminal emulation to ‘port’ as above, 8, n, 1, CTS/RTS, Enter AT mode by sending ’+++’ Send the character ’P’ from one modem. This modem will now ping and report back the reply with RSSI indication Blizzard Radio Modem Configuration Mode (offline) Commands can be set using a standard Terminal program or by sending the relevant ASCII characters. Each Command must be followed by the Carriage Return or ‘Enter’ except “+++” Note All commands are entered in upper case Command Description Response from Blizzard Enter Configuration Mode +++ ? F H Note: This command must be sent as a string with no characters in front or behind. This is to ensure that the +++ is not mistakenly received in mid-data. ( is not to be used with +++). Retrieve the current register values Pre-configured factory defaults; R1=7F7F7F R2=7F7F7F R3 = Ch2 (869.450MHz) R4 = 7 (+20dBm) R5 = 1 (19K2) Help Ping Mode This sends a ping request . P On receiving, the recipient Blizzard Modem will respond with its address and the level of RSSI (Received Signal Strength) The Ping command is continuously repeated every 1 second until any command or character is entered. Blizzard responds with status info Blizzard responds with all register values ‘OK’ Brief description of commands The originating BLIZZARD modem module will respond with the recipient BLIZZARD modems’ address. eg. Received from 7F7F7F (D5) Where 7F7F7F = the recipient address D5= RSSI RSSI Is a hex value corresponding to the received signal strength Min = 20hex S Save Configuration ‘SAVED’ Q Exit configuration mode and return to online mode No response Blizzard Radio Modem Register Setting (Configuration Mode) The internal registers enable various parameters to be controlled. To set a register type ‘R#=x’ where # is the register number (1-6) and x is the value to set For example, to set the channel to channel 3 type : R3=3 (Where is carriage return or enter on the keyboard) The modem will then return ‘OK’ or ‘Error’ if an incorrect command is entered. Save the changes by typing : S The modem will return with ‘SAVED’ Default values are shown in BOLD Register Value Range R1 0000 - FFFFFF (24 bit address) R2 0000 - FFFFFF (24 bit address) R3 Description Example Sets the recipient Blizzard modem Address R1=0001 (Data sent is addressed to Blizzard modem with address 0001) Set own Blizzard Modem address R2=F001 (Data sent is from Blizzard modem with address F001) Set RF channel R3=2 (Transmit on Channel 2) Set the RF Transmit Power output* R4=7 (sets Transmit Power to max)* Set the RF baud rate* R5=3 (sets the RF data rate to 56Kbps) CH0 to CH4 0 = +1dBm 1 = +2dBm 2 = +5dBm 3 = +8dBm 4 = +11dBm 5 = +14dBm 6 = +17dBm 7 = +20dBm R4 0 1 2 3 R5 = 9,600 = 19,200 = 28,800 = 56,000 *Note: • Reducing Tx power reduces battery consumption! • Reducing the baud rate will increase the range!
