Refer to Latest Version Information for reference info on latest firmware version numbers.
NOTE: this module uses the VOSHPS type of sensor front-end. All SWR modules built after 1 Oct 98 will use this sensor front-end. Also reference the VOSHPS 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).
A Address acknowledge - returns address of module, terminated by <crlfetx> - e.g. #SWR01A SWR01<crlfetx> - NOTE: SWR01 is the default address of the SWR 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. B Output both calibrated and raw values - outputs both calibrated and raw data values, as follows: SWR : counts<crlfetx> - example: #SWR01B 753.3 : 32265<crlfetx> - SWR is shortwave radiation in watts per meter square; raw values are 16-bit counts. - C language format: "%7.1f : %7u\r\n\x03" C Output calibrated data - outputs calibrated value, W/M^2, as follows: - example: #SWR01C 735.2<crlfetx> - C language format: "%7.1f\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: #SWR01D2000/01/18 10:35:15 will set the date to 18 January 2000 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.
F PCMCIA card access (only if FLASH card installed) - there are 5 'F' commands available for accessing the 4 or 8 megabyte FLASH memory card used for data storage. These commands allow reading the card contents via the RS-485 command link, storing EEPROM contents for archival purposes, and FLASH card erasure. - the lowest 128 kilobyte block of the FLASH card is reserved for system information. As of the current revision (VOSSWR53 v2.3), only stored EEPROM contents reside here, beginning at byte 257 (100h) and continuing for 1024 bytes (4FFh). The rest of the 128 kilobyte block reads as all FFh. This block may be erased without affecting data stored in the rest of the FLASH card. FB - Read any 512 byte block, hex - any 512 byte block from 1 to 8192 may be chosen as the starting block. Block 1 is the default starting point. - blocks are formatted as 32 bytes (64 ASCII characters) of HEX-ASCII per line by 16 lines per 512 byte block. - example (default start block - note EEPROM info stored by 'FS'): #SWR01FB Start block #  -> (hit ENTER here for default) FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFF57484F492F47454F464600FFFFFFFFFF4D4B3100FFFFFFFF FFFFFFFFFFFFFFFF30303100FFFFFFFF31354D415239350041495200FFFFFFFF FFFFFFFFFFFFFFFF53422D324100FFFFFFFFFFFFFFFFFFFF2D00FFFFFFFFFFFF 2D00FFFFFFFFFFFF47454F464600FFFFFFFFFFFFFFFFFFFF5454384250520000 FFFFFFFFFFFFFFFF312E3100FFFFFFFF30344150523935002D00FFFFFFFFFFFF 2D00FFFFFFFFFFFFFFFFFFFFFFFFFFFF2D00FFFFFFFFFFFFFFFFFFFFFFFFFFFF 4E4F2043414C00FF425052303100FFFF25372E326600FFFFFFFFFFFFFFFFFFFF FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF - to read the next block, hit ENTER. - to quit, hit X followed by ENTER. - Note 1: Blocks 1, 2, and 3 contain the 1024 bytes of EEPROM image, if written by the 'FS' command below. The EEPROM image begins at the middle of block 1 and ends in the middle of block 3. - Note 2: The first DATA record is written at block 257 (above the first 128 Kbyte reserved system info area at card physical address 20000h). FR - Read data record, formatted - any 256 byte record from 1 to 15872 may be chosen as the starting record. Record 1 is the default starting point. - records are formatted as 1 line of date and time followed by 60 minutes of SWR readings in W/M^2 sent as 10 lines of 6 minutes each. Readings occur on the minute, beginning with minute 0 and ending at minute 59, with the record written to the FLASH card at 59 minutes, 01 seconds of each hour. - example (default start record): #SWR01FR Start record # -> 2000/01/09 09:59:00 721.53 721.50 721.50 721.53 721.53 721.50 721.50 721.50 721.45 721.42 721.45 721.45 721.55 721.53 721.55 721.55 721.55 721.45 721.55 721.58 721.55 721.60 721.53 721.55 721.53 721.50 721.45 721.53 721.58 721.60 721.62 721.60 721.55 721.50 721.53 721.48 721.58 721.58 721.50 721.48 721.48 721.53 721.45 721.48 721.50 721.50 721.48 721.45 721.50 721.42 721.40 721.38 721.42 721.45 721.45 721.45 721.40 721.38 721.38 721.33 - to read the next record, hit ENTER. - to quit, hit X followed by ENTER. - Note 1: values of ??? indicates no reading was available from the VOSHPS for that minute; each minute's data is placed at a fixed location in the storage array corresponding to the minute when the data was acquired. Values of Na indicates an unused portion of the FLASH card has been accessed. This value corresponds to the all FFh condition of the erased FLASH card. - Note 2: The first data record is written at block 257 (above the first 128 Kbyte reserved system info area at card physical address 20000h). Using the 'FB' command above and selecting block 257 as the start block, you may inspect the packed binary format of the data at record 1. Since each block is 512 bytes long, you will see data from 1 records at a time. - See FLASH Record Format for FLASH card internal storage format. FS - Store EEPROM constants - on startup, 1024 bytes of the EEPROM are read into system RAM and mapped onto a data structure of miscellaneous system information and calibration constants. This area of system RAM may be modified using the 'U' command, and the EEPROM may then be re-written with the modified information. As an additional backup for possible data processing use later, this information may also be written out, in binary format, to the system/info area of the FLASH memory card. - example: #SWR01FS System info written to PCMCIA<crlfetx> - NOTE: The system/info area must be erased prior to each use of the 'FS' command. - the system area may be read in HEX-ASCII format by reading blocks 1, 2, and 3 with the 'FB' command above, or as part of the binary dump of the entire FLASH card using the 'XMODE' command below. - See FLASH Record Format for FLASH card internal storage format. FE - Erase entire card (Y/N) - use ONLY if you wish to erase the entire FLASH card. This command takes several seconds to complete. After each 128 Kbyte block erase, a dot (.) is sent, followed by a "Cleared" message when done. - upon entry, you are prompted "Do you really want to erase? Y/[N]" The default response is NO; in fact any response other than uppercase Y will abort with "Aborting<crlfetx>". - example: #SWR01FE Do you really want to erase? Y/[N]<crlf> Y Erasing Flash Card...................................<crlf> Cleared<crlfetx> - upon completion, the next hour record will be written at record 1. FI - Erase system/info area (Y/N) - this command allows erasure of the system area ONLY, and in particular, the EEPROM info stored with the 'FS' command above. The data area will NOT be erased by this command. - upon entry, you are prompted "Do you really want to erase system info? Y/[N]" The default response is NO; in fact any response other than uppercase Y will abort with "Aborting<crlfetx>" - example: #SWR01FI Do you really want to erase system info? Y/[N]<crlf> Y Erasing...System info cleared<crlfetx> H Help - #SWR01H - 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: Firmware VOSSWR53 V2.3 Module clock 2.4576 Mhz A - Address acknowledge B - Output both raw and cal C - Output calibrated data D - Set RT clock date/time: 'YY/MM/DD HH:MM:SS' F - PCMCIA card access FB - Read any block, hex FR - Read data record, formatted FS - Store EEPROM constants FE - Erase entire card (Y/N) FI - Erase system/info area (Y/N) H - Display Help message I - Report ID information L - Report ID, serial #, cal info, etc. P - Enter polled test mode R - Output raw data T - Enter test mode U - Update EEPROM constants - password 'OK' V - Output last hour averaged data XMODE - XMODEM Dump PCMCIA card via console Note: 'F' and 'XMODE' not present unless FLASH card is installed
I Report ID information - #SWR01I - displays the text information stored in EEPROM, with headers as follows, each line terminated in crlf: MODADR: ( 5 bytes text) module address MODMFG: (16 bytes text) module manufacturer MODMOD: (16 bytes text) model number MODSER: ( 8 bytes text) serial number MODDAT: ( 8 bytes text) manufacture date SENMFG: (16 bytes text) sensor manufacturer SENMOD: (16 bytes text) model number SENSER: ( 8 bytes text) serial number SENDAT: ( 8 bytes text) manufacture date SFTMFG: (16 bytes text) program origin SFTNAM: (16 bytes text) program name SFTREV: ( 8 bytes text) serial number SFTDAT: ( 8 bytes text) revision date CALFAC: (16 bytes text) calibration facility CALPER: (16 bytes text) calibration technician CALDAT: ( 8 bytes text) calibration date DATFRM: (64 bytes text) calibrated data output format DATDES: (64 bytes text) calibrated data description DATUNI: (64 bytes text) calibrated data units RAWFRM: (64 bytes text) raw data output format RAWDES: (64 bytes text) raw data description RAWUNI: (64 bytes text) raw data units - the last scan sent is terminated by <crlfetx>. - 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 PCMCIA card status. Normally, after an initial <crlf>, 8 lines of info are provided, as follows: #SWR01L<crlf> module id from EEPROM<crlf> module serial number from EEPROM<crlf> firmware name and version number from program EPROM<crlf> crystal frequency from EPROM calibration date from EEPROM<crlf> current date and time<crlf> SWR cal constants A, B, C, D PCMCIA card installed - PCMCIA card status<crlf> PCMCIA card 1 hour records used, available<crlfetx> - example normal response (8 lines plus initial <crlf>): SWR01 001 VOSSWR53 v3.0 2.4576 Mhz NO CAL 99/04/10 11:23:35 SWR: 0.00000e+00 2.40000e-02 0.00000e+00 0.00000e+00 EDI Intel-compatible 8MB PCMCIA CARD present - CARD OK! Records used: 125; available: 7811 - the last line is terminated by <crlfetx>. - NOTE 1: after initial startup, cal constants (which reside in the VOSHPS sensor front-end) will not be displayed. The message "Use 'Q'uery command to get constants from VOSHPS front end" will be displayed. See 'Q' command below. - NOTE 2: if an Intel Type 2+ 4MB PCMCIA card is installed, the card present line will display: Intel Type 2+ 4MB PCMCIA CARD present - CARD OK! - NOTE 3: if no PCMCIA card present, the last two lines will be replaced by "No PCMCIA card installed" message. P Enter polled test mode - responds with individual scans of data in the 'B' command response format, except <crlf> terminator only. Upon receipt of any character except ESC, another scan of SWR data is sent. For example: #SWR01P 701.6 : 32065<crlfetx> send <cr> (or other character) 701.6 : 32065<crlf> send <cr> (or other character) 701.6 : 32065<crlf> . . - the command terminates on receipt of an ASCII ESC (1Bh) character. The last scan sent is terminated by <crlfetx>. Q Query command retrieves cal constants from VOSHPS sensor front-end. - this command will take several seconds to execute; it must power up the VOSHPS board, wait for VOSHPS initialization, then request a set of cal constants. - the message "Requesting cal constants - " will be displayed immediately. After the above noted delays, the message "OK!" will be appended if successful, "FAILED!" if not successful. - example: #SWR01Q Requesting cal constants - OK! R Output raw value (currently same as 'B' command) - outputs both calibrated and raw data values, as follows: RH% degc : counts counts<crlfetx> - example: #SWR01R 706.1: 32075<crlfetx> - C language format: "%7.1f : %7u\r\n\x03" T Enter test mode - responds with continuous scans of data in the 'B' command response format, except <crlf> terminator only. For example: #SWR01T 706.1 : 32075<crlf> 706.1 : 32075<crlf> 706.1 : 32075<crlf> 706.1 : 32075<crlf> . . - the command terminates on receipt of an ASCII ESC (1Bh) character. The last scan sent is terminated by <crlfetx>. U 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. #SWR01UOK. 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. - the '0' choice for 'Exit without update' leaves the module RAM and EEPROM in its original state. - the '8' choice for 'Enter VOSHPS cal constants' passes commands through the SWR C51 logger board to the VOSHPS sensor front-end board vis RS-485. There are some startup delays while the VOSHPS is powered up, as well as some half-duplex comms delays. After selecting '8' from the menu, it will take several seconds to get the 'OK' prompt from the VOSHPS (if it fails to respond, try again after the menu re-displays). At the OK prompt, you may read existing or write new cal constants only. Unrecognized commands will result in a 'Bad command' response. If you get stuck, enter 'Q' to quit VOSHPS update without making any changes. For complete details on the VOSHPS EEPROM Update command, see the document "VOSHPS Front-End Module Command Set". - all responses to prompts must be terminated with <cr>. The final response from the module upon exit is <crlfetx>. NOTE 1: Upon completion, the newly updated module address will not take effect until the next reset or power-up. V Output the latest 1 hour average values - outputs the average of the 1 minute values of the most recent hour; update is concurrent with the write to FLASH of the current hour's data at minute 59 of each hour. - example: #SWR01V 776.3<crlfetx> - see 'C' command for values and format XMODE XMODEM Dump PCMCIA card via console in RS232 mode only; (only if FLASH card installed) The following description assumes PCPLUS for terminal software, but any terminal program capable of XMODEM transfer should work. On entry, the module will prompt: 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: Sent 89 blocks - done Restore terminal speed to 9600 then hit any key After resetting speed to 9600 baud and hitting a key, the module will send a "\r\n" Ignore occasional gibberish when changing baud rates! Note: Only data record portion of FLASH card is dumped via XMODEM; See FLASH Record Format.
