Introduction Wireless Access in Vehicle Environments (WAVE) is communication standard that provides Vehicle to Vehicle communication (V2V) and Vehicle to Infra-structure (V2I) and is proposed by IEEE. This standard considers ITS service and application of vehicle safety service. On Board Equipment
(OBE) is vehicle device. WAVE sends packet frame and receives packet frame at short time in the radio environment that vehicle moves high speed. This standard is communication scheme that IEEE 802.11p scheme changed to vehicle environment. WAVE needs device platform and communication module in vehicle, vehicle antenna, and antenna and communication module on the road. This document is user manual about WAVE OBE in vehicle. 5 / 17 2. OBU Interface 2-1. Appearance Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30
[picture 1] WAVE OBU Front View
[picture 2] WAVE OBU Behind View At the right , there is Power Switch,SD CARD connector at the behind, 12v power port, Ethernet port, UART port, RF Antenna connector, GPS Antenna connector. Terminal connection in chapter 3 is using UART port at [picture 1]. 6 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 2-2. OBE connection view connect each components like above. 7 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 3. Connect with terminal 3-1. Check port After connect USB2Serial Cable with notebook, move to Start-> Control Panel -> System ->
Hardware -> Device Manager -> Port. (It assumed that USB2Serial Cable PC Driver already installed, it can be installed using CD within cable package). Check the USB Serial Port(COMxx). 8 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 3-2. Terminal Program Setting 3-2-1. Run the terminal program In this manual, Explain using teraterm s/w. (free license, it can be downloaded from internet) After run Teraterm, move to Setup->Serial port at the top menu.. 3-2-2. Port setting Set the port same as that checked with Device Manager, and Baud rate is 115200, Data is 8bit, Parity is none, Stop is 1 bit, and Flow control is none 9 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 3-2-3. Terminal setting complete If screen shows like below, it is ready.. 3-2-4. OBE power on Turn on OBE, and screen shows these messages below, booting is successful, and terminal is connected, too. It is normal state can be operated commands in chapter 4. 10 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 4. Basic Commands rst this command for reboot. txpkt Send optional packets. The usage is, txpkt [length] [#of frame] [pwr level] [rate] [time-tick]
There is an example, sending packet is 1000 bytes, frame count 3000, RF Tx power 1, datarate 9Mbps, and 2ms time delay. 11 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 cntmac Printout Tx or Rx packet count. For example, it already sent 3000 packets using txpkt above, screen shows below. clrcnt Reset counted numbers. after reset, screen shows below. 12 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 Change TX power 1) Temporary Change power Change RF Tx power level. Arguments is one of numbers from 1 to 8. There is an example change Tx level to level 7. It will be adjust immediately during operation, and reset after reboot. 2) Permanent Modification Change RF Tx power level. Arguments is one of numbers from 1 to 8. There is an example change Tx level to level 2. (It will be adjust after reboot) 13 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 Change frequency 1) temporary change fchange Change the RF frequency. Argument is one of 40, 50, 60, 70, 80, 90, 900, 910, 920, 800. Argument 40 means 5.840Ghz, 50 means 5.850Ghz, 60 means 5.860Ghz, 70 means 5.870Ghz, 80 means 5.880Ghz, 90 means 5.890Ghz, 900 means 5.900Ghz, 910 means 5.910Ghz, 920 means 5.920Ghz, and 800 means 5.8000GHz. There is an example changing frequency to 5.870GHz below. It will be adjust immediately during operation, and reset after reboot. 2) Permanent Modification(5.90Ghz, 5.8000GHz not supported) Change the RF frequency. Argument is one of 0x28, 0x32, 0x3c, 0x46 and 0x50. Argument 0x28 means 5.840Ghz, 0x32 means 5.850Ghz, 0x3c means 5.860Ghz, 0x46 means 5.870Ghz and 0x50 means 5.880Ghz. there is example change frequency to 5.860Ghz below. and it will be adjust after reboot. 14 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 Change Datarate arguments are 0x03, 0x06, 0x09 and 0xC 0x03 is 3Mbps, 0x06 is 6Mbps, 0x09 is 9Mbps and 0xC is 12Mbps. there is the changing screen about 0x06 -> 6Mbps below. after reboot, adjust below. 15 / 17 Subject WAVE OBE Manual Document Code last modification date 1.3 2014-09-30 Change TX only Mode (non modulation) Change to the TX only Mode.
