ASIMET WIND MODULE VERSION 4.xx with CompactFLASH COMMAND SET

See ASIMET MODULE OPERATIONS document for instructions on how to hook up the comms link to your PC and RS-485 adapter.
Refer to Latest Version Information for reference info on latest firmware version numbers.

CFLASH NOTE 1 - Firmware Ver 4.xx has been tested using SanDisk CompactFLASH cards (256 MB and 64 MB) with SanDisk CompactFLASH PC Card (PCMCIA) Adapters on WHOI VO80053 Rev C/D CPU boards.

CFLASH NOTE 2 - CompactFLASH cards MUST be formatted using the I command choice in the FOK command menu. CompactFLASH cards may be read on a PC and will contain 2 files: a .INF user-defined Info file, and a .DAT Data file. Processing of the new .DAT file is identical to processing the data files from older PCMCIA-based loggers, since the data file record format is unchanged.

Note 1: This module uses the PICWND type of sensor front-end with RM Young Wind Vane. Reference the PICWND Front-End Module Command Set document.

Note: commands sent are indicated in BOLD, responses in normal text. <crlf> represents ASCII carriage return and line feed; <crlfetx> represents ASCII carriage return, line feed, ETX (03h).

Command Description

A Address acknowledge
- returns address of module, terminated by <crlfetx>
- example:
  #WND01A WND01<crlfetx>
- NOTE: WND01 is the default address of the WND module; it may be changed by the 'U' command but any failure of EEPROM will result in the use of the default address. In the event of EEPROM failure, a message is sent to the RS- 232 console port on startup. In addition, use of defaults is reported in the 'L' command.
C Output calibrated data
- outputs calibrated value as follows:
  Ve Vn WSavg WSmax WSmin LastVane LastComp TiltXAvg TiltYAvg<crlfetx>
- example:
  #WND01C 2.34 1.45 4.9 5.2 4.7 123.1 234.5 0.2 0.3<crlfetx>
- C language format: "%6.2f %6.2f %5.1f %5.1f %5.1f %6.1f %6.1f %6.1f %6.1f\r\n\x03"
D Set RT clock date/time: 'YYYY/MM/DD HH:MM:SS'
- on module startup, the date and time are initialized from the battery-backed RTC on the DS87C530 chip. The 'D' command accepts a fixed format string of exactly 19 characters representing date and time. For example, sending the following command:
  - #WND01D2007/04/18 10:35:15
  will set the date to 18 April 2007 at 10:35:15 AM.
- the module returns <crlfetx> in acknowledgement.
- the time will be set at the instant that the last digit is sent; thus you may enter the module address, command and first 16 characters of the date and time, and finally enter the 19th character in sync with your reference clock. The current date and time may be determined using the 'L' command.
FOK Menu-driven CompactFLASH command operations
- Upon FOK command entry, and between each command, you will see a prompt:
  Enter Flash Cmnd, ? or H for Help:
- a request for Help returns this message followed by another prompt:
```
    Flash Help (All commands end with Enter)

    C - Read card Capacity
    D - Read the card Directory
    E[I,D] - Erase the contents of the Info or Data files
    F[W,R] - Write or Read the Info File
    H{?} - Display this menu
    I - Format & Initialize the card file structures
    P - Read the next write & read sector Pointers
    R{H,A}{SEC} - Read the next card sector (see P command above)
             optional {H,A} -> Hex ASCII or printable ASCII
	     optional {SEC} -> specific sector number
    S - Read the CF status (reg 7 and the ERRORs (reg 1), disp as HEX-ASCII
    W{nnn} - Write 512 byte Test Msg to the Data file
             optional {nnn} -> 1-3 digits of additional sectors to write
    Q - Quit Flash operations

    Enter Flash Cmnd, ? or H for Help:
    
```
- description of FOK Menu Commands:
  - C - displays card capacity info
  - D - displays a card directory (similar to a DOS "dir" command output):
```
Volume in drive is NEWLGR53
Directory of CF:
2007/04/24  19:10                   35 LOGR001.INF
2007/04/25  16:42               523904 LOGR001.DAT
               2 File(s)         523939 bytes
                              256179584 bytes free
       
```
  - EI - erases the contents of the INFO file, and sets its size to 0
  - ED - erases the contents of the DATA file, and sets its size to 0
  - FR - reads the free-format ASCII contents of the INFO file
  - FW - prompts for up to 600 characters of user info; CTRL-C terminates entry into the INFO file
  - I - formats & initializes the CFLASH card for use in the logger. A series of prompts guides you through the process. This must be done before the logger will recognize the card and use it for data storage.
  - P - reads the next write and read sector pointers. In particular, the next write sector pointer always indicates the last sector of data on the card. This is useful with the XMODE command.
```
  
Flash Write Pointer @ 1345
Flash Read Pointer @ 258
       
```
    The write sector pointer is always restored to the currently available sector for new data whenever the logger is powered up. The read pointer is reset to the INFO file sector on power up.
  - R - read command allows a number of options, the most useful being the RH and RH{SEC} options. For example, to see what's in the last DATA sector, use the P command above to find the current write sector, then use that in the RH{SEC} command to see the values. So, for the value of the Flash Write Pointer above, send RH1345 to see the 512 bytes of that sector:
```

```
    If you want to read subsequent contiguous sectors, just do an RH at the next prompt, and the next sector in sequence will display (1346 in this example). See Record Format to decode the HEX dump.
  - S - CF status info - internal WHOI use only
  - W{nnn} - writes test data to the current write sector in the DATA file. Used only for test. If you use this function, you should ED to erase the DATA file before deploying the logger, unless you wish to incur the wrath of your data processing guru!
  - Q - quit Flash ops and return to logger command mode
- New CFLASH Card Prep - when installing a CFLASH card for the first time, it must be initialized for use in the logger. The "I" command, Format & Initialize card file structures is used to prepare the CFLASH card for use. You will be prompted for a Volume name, an INFO File name, and a DATA file name. The 3 character suffix of the INFO file is always .INF and the 3 character suffix of the DATA file is always .DAT Once formatting is complete, you can get a directory with a "D" command, or write user info into the INFO file with the "FW" command, then read the INFO file back with the "FR" command.

H Help

#WND01H - a multiple line response with text similar to the first line of each command description in this document as the help line, with each line terminated <crlf> and final line terminated <crlfetx>, as follows:

NOTE: this information resides in EEPROM. Most items are completed at time of manufacturing test, but may be modified using the 'U'pdate command. Only module address is necessary for correct module operation.

L Report ID, serial #, cal info, etc.
- the 'L' command provides miscellaneous status information about the module in a multi-line response. The number of lines in the response may vary depending upon the EEPROM and FLASH card status. Normally, after an initial <crlf>, these lines of info are provided, as follows:
  #WND01L
```
    module id from EEPROM<crlf>
    module serial number from EEPROM<crlf>
    firmware name and version from program EPROM<crlf>
    calibration date from EEPROM<crlf>
    current date and time<crlf>
    Compact Flash Card present - Compact Flash card status<crlf>		   
        
    - example normal response (with CompactFLASH card):
    WND01

```
- the last line is terminated by <crlfetx>.
- NOTE 1: if a FLASH card is installed, a message will indicate this and either OK or NOT LOGGING status
- NOTE 2: if no FLASH card present, the last two lines will be replaced by "No CompactFLASH card installed" message.
- NOTE 3: if the EEPROM compass flag value, COMP_FLAG, is 1 (see Enable/Disable Compass under the UOK command for info), Compass use disabled! will be displayed between the serial number and firmware version lines.
- NOTE 4: if the NOAA/SEAS flag value is 1 (see Enable/Disable NOAA/SEAS-Compatible message under the UOK command for info), AUTOIMET NOAA-SEAS message enabled! will be displayed between the serial number and firmware version lines.
P Enter polled test mode
- same as 'T' command below, except after initial scan, waits for any character (except ESC) to send next scan.
R Output raw value
- outputs raw data values, as follows:
  sample_time, pulse_count, compass degrees, east vector (m/s), north vector (m/s)<crlfetx>
- example:
  #WND01R 5.0 248 302.7 -0.968 0.250<crlfetx>
- C language format: "%5.2f %6d %5.1f %6.3f %6.3f\r\n\x03"
T Enter test mode
- responds with continuous scans of data following initial 'Wait...' message, except <crlf> terminator only (no ETX).
- scans occur every 5 seconds (counting interval of interface)
- data is pulses/5 sec, speed (M/S), wind direction degrees, vane direction degrees, compass degrees, tilt-x degrees, tilt-y degrees;
  example:
  #WND01T
```
    Wait...
    249  4.9  285.1  341.8  303.3   0.8   0.4<crlf>

```
- the command terminates on receipt of an ASCII ESC (1Bh) character. The last scan sent is terminated by <crlfetx>.
UOK Update EEPROM contents
- enters the update mode after confirmation of 'OK' password. New EEPROM values may be entered in this mode.
- upon initial entry, you must send the letters OK after the command or the command is ignored, e.g. #WND01UOK. Upon receipt of the correct password, a set of prompts will be issued to allow entry of new module address, module manufacturer's info, sensor info, software info, calibration facility info, raw and calibrated output format info, VOSHPS calibration constants, display entire info area, and exit with or without update.
- Enable/Disable Compass use in vector calculations. A special configuration setting allows compass use to be disabled in all calculations while still displaying the current compass values and logging the compass data to FLASH. This option is typically used for testing purposes on ship-mounted systems only. This option is NOT listed in the EEPROM menu.
  - At the "Enter selection ->" prompt following the standard menu, hit C followed by <cr> to get the current compass flag value and the prompt to change it, as below:
```
    COMP_FLAG: 0
    Enter 0 or 1 ->
```
  - Enter 0 (ZERO) to enable the use of the compass during calculations (NORMAL OPERATION).
  - Enter 1 (ONE) to disable the use of the compass during calculations.
  - Don't forget to "Exit and update EEPROM" with menu choice 9 when done, then cycle power for the new setting to take effect.
  - Note that the L command will display Compass use disabled! if the COMP_FLAG value is 1.
- Enable/Disable NOAA/SEAS-Compatible message allows an ASIMET WND module to be substituted for a complete AUTOIMET shipboard system, providing date, time, and Ve and Vn values in a string that is broadcast out the console port once per minute. The format is compatible with the standard AUTOIMET message, with other ASIMET module values set to zero. This option will only broadcast the message if the WND module is set for RS232 comms.
  - At the "Enter selection ->" prompt following the standard menu, hit S followed by <cr> to get the current NOAA/SEAS flag value and the prompt to change it, as below:
```
    NOAA_SEAS_MESSAGE (1 = ON): 0
    Enter 0 or 1 ->
```
  - Enter 0 (ZERO) to disable broadcast of the NOA/SEAS message.
  - Enter 1 (ONE) to enable broadcast of the NOA/SEAS message.
  - Don't forget to "Exit and update EEPROM" with menu choice 9 when done, then cycle power for the new setting to take effect.
  - Note that the L command will display AUTOIMET NOAA-SEAS message enabled! if the NOAA/SEAS flag value is 1.
  - Typical NOAA/SEAS-Compatible broadcast message (note zero values for other modules):
    2008/05/06 14:45 0.00 0.000 0.000 0.0 0.00 0.000 0.0 1.23 -2.58
- the '0' choice for 'Exit without update' leaves the module RAM and EEPROM in its original state.
- all responses to prompts must be terminated with <cr> (Enter)
  The final response from the module upon exit is <crlfetx>
- NOTE 1: Upon completion, the newly updated module address, the compass enable/disable setting, and the NOAA/SEAS message setting will not take effect until the next reset or power-up.
XMODE XMODEM Dump CompactFLASH card via console
- XMODE command only works in RS232 mode and only if CompactFLASH card is installed
- CompactFLASH cards will take a LONG TIME to read this way - the preferred method of reading a large .DAT data file is to remove the CFLASH card from the module and read it on a PC. Two files will be recognized by the PC, a .INF INFO file which can contain up to 600 characters of user information, and a .DAT DATA file which contains the logger data records. See the FOK command above.
- This command is somewhat rudimentary; if you must dump data this way, use the L command to display the current directory and file sizes on the CFLASH card. You can then estimate where to start dumping data, based on one 740 byte record per hour, and a CFLASH sector size of 512 bytes. Or use the FOK command to look at the HEX values of particular sectors to decide where to start the dump.
- Command dumps data from the requested starting sector for up to 2048 512-byte sectors (i.e. a maximum of 1 MB of data). Sector 322 is the first sector of the data file on the CFLASH card.
- On command entry, requests: Start sector # (322 is first, 0 aborts) -> followed by: Number of sectors (1 to 2048, default is 512) ->
  - i.e. to get first week of data (168 records -> 1 week), enter 322 as the start sector, and 243 for the number of sectors.
  - add 243 to your start sector number to find the start of subsequent week-long portions of data; i.e. if you entered 322 to start at the first sector on the FLASH card, subsequent weeks of data start at sector 565, 808, etc...
- Typical example - the following description assumes PCPLUS for terminal software, but any terminal program capable of XMODEM transfer should work.
  - On entry, module will first prompt for start sector:
    Start sector # (322 is first, 0 aborts) ->
    Enter a valid sector # (see discussion above)
  - followed by a prompt for number of sectors:
    Number of sectors (1 to 2048, default is 512) ->
    Enter a valid sector count (see discussion above)
  - Next, you'll be prompted:
    Set terminal speed for 38400 then hit any key
  - After setting speed and hitting a key, you will see:
    XMODEM Send Function
    Waiting for start...
  - Start a transfer (PgDn in PCPLUS) - on completion, you will see something like:
    Sent 160 blocks - done
    Restore terminal speed to 9600 then hit any key
    NOTE:"blocks" here are XMODEM blocks of 128 bytes each
  - After resetting speed to 9600 baud and hitting a key, module will send a "\r\n"
  - Ignore occasional gibberish when changing baud rates!
- Note: Only the .DAT data file portion of the CompactFLASH card is dumped via XMODEM; See CompactFLASH WND Record Format.
