AntiLog [Dual Channel]	V4.0e	V4.0e   Sep 2007   [Active Release: Dual Channel Version] Panel LEDs show when media is full in record mode without having to wait until incoming serial data arrives. Slightly faster operation due to advances in development compiler release. Microcontroller SLEEP mode is now implemented during shutdown to improve 'P' product performance. Updated 'About' display provides additional information and format compatible with single channel (V3.3e) release. V4.0d   Jul 2007   [Dual Channel Version] Improved access code to non-volatile setting store. Power consumption reduction when media card is not present. RTC bus code improvements to reduce power consumption. Media Insertion code made more compatible with older (slower) cards. Pressing and holding the 'On' button for baud reset no longer clears channel 1 playback settings. RTC device type shown in 'About' menu. V4.0c   Mar 2007 [Dual Channel Version] New NOLOG (Option 'N') available for equipment initialisation only. Support for new lower power RTC device. Media extract events now update main menu as well as media insertion events. Further improved recording and playback processing speeds. Improved millisecond time stamp accuracy. Battery check now looks more like a bar display on terminal output. V4.0b   Sep 2006   [Dual Channel Version] Media full now reported properly (was not flashing red properly when full for all media sizes). Improved media recovery function. Panel LED now flashes yellow to confirm a new clock time and date input. This therefore means a unit will now flash yellow to confirm it has received a new time and date using the AntiLog time transfer function from another unit. V4.0   Jul 2006   [New Dual Channel Version] General Major embedded software upgrade to support single and dual channel operation. Recording and playback engines completely re-written. Single channel and dual channel recording and playback now possible from a single AntiLog unit (hardware REV C or better required). Each channel is independently configurable for both record and playback. Designed to easily record two streams of 115,200 baud data at full rate. New file system to support dual channel data logging. File system backward compatible with V3.2. Better file system inter-operability with multicard PC readers. Much improved time stamping accuracy with all media types. New SLEEP code to reduce power consumption by up to 25% when idle. New visual feedback for two button erase and baud rate reset operations. New file transfer protocol (ASLMTx) replaces 'X-Modem' support (see AntiLogReader). Panel LED gives a single flash when unit is switched on even if LEDs are disabled to show user has indeed switched the unit on. Recording Greatly enhanced options for 'On' and 'Off' button actions during record. Independent polling functions per channel. Up to 4 user defined commands can be assigned to buttons and polling functions. New 8bit and NByte time stamping modes for record and playback. Able to time stamp every incoming byte with NByte time stamping if required. Switch to enable/disable explicit time stamping of button events. End of line character can now be user defined. 'Digital Bit State' can now be inserted into channel data during record. Playback Real time playback now possible from two channels simultaneously. Real time playback can use time values in NMEA sentences if no time stamping is present. Single channel playback can be from any recorded channel. Time stamp expansion now selectable for HEX playback. Recording channel number can be embedded in output stream. Ability to play back RAW as well as ASCII expanded time stamps. Configuration Up to 4 groups of complete user settings can be saved and retrieved later. About menu enhanced to give more comprehensive settings overview. About menu item now shows DCARD lid serial number if available. Better user feedback during time and date entry. User command can now be entered as a hexadecimal string with an offset. Ability to copy options from one channel to another. 'M' Option Time stamping of ICD-GPS-15x messages now possible to 1mS resolution. Real time playback can use embedded time stamp information. User can select whether time stamps appear in playback output stream or not. Custom message can be inserted in ICD-GPS-15x data stream as an event (e.g. 'On' and 'Off' button events).
AntiLog [Single Channel]	V3.5	V3.5   Feb 2008   [Active Release: Standard Single Channel Version] Real time clock was still showing as valid even if RTC chip FAIL flag was set. Improvements to the way 'RTS' is handled. 'RTS' action is now actively reset by extended 'On' button push during startup. 'RTS' action is reset as soon as factory defaults are requested in 'General' menu. I2C bus control of RTC chip further improved. V3.4   Nov 2007   [Standard Single Channel Version] Time synchronisation at start up worst case has been reduced from 1 second to 0.5 seconds, so on average, AntiLog starts up even faster. Clock calibration calculation error introduced in V3.3 which may have caused unwanted clock drift during record and playback. Date formatted output for "dd/mm/yyyy" was broken for dates greater than 2009. Improved 'About' menu now includes details of detected RTC device (as per V4.0) and media format. 'About' menu now automatically updates if media is physically inserted or extracted from a unit. Alterations to menu system text for improved clarity. Faster user command poll output rates. Can now achieve 25Hz (40mS period). Menu system now automatically determines connected terminal <CR>, <LF> or <CR><LF> setting (prevents 'double' screen updates seen with some terminal programs). Significant improvements to 'Button Event' handling during the NSAMPLE recording mode. Key selections changed for 'Recording Options' menu for compatibility with future developments. Improved handling of invalid date and time entry. Improvements to User Command entry including preview in ASCII or HEX depending on current content (as per V4.0). Some non printable characters are now shown as codes during entry and in preview, e.g. "<CR>", "<LF>", "<TAB>". Improved I2C bus handling including power savings after activation. V3.3e   Sep 2007   [Standard Single Channel Version] Panel LEDs show when media is full in record mode without having to wait until incoming serial data arrives. Slightly faster operation due to advances in development compiler release. Microcontroller SLEEP mode is now implemented during shutdown to improve 'P' product performance. Updated 'About' display provides additional information and format compatible with dual channel (V4.0e) release. V3.3d   Jun 2007   [Standard Single Channel Version] Improved access code to non-volatile setting store. RTC bus code improvements to reduce power consumption. Media Insertion code made more compatible with older (slower) cards. V3.3c   Mar 2007   [Standard Single Channel Version] Support for new low power RTC device used in production. Media extract events now update main menu as well as media insertion events. Further improved recording and playback processing speeds. Improved millisecond time stamp accuracy. Battery check now looks more like a bar display on terminal output. V3.3b   Sep 2006   [Standard Single Channel Version] Change to embedded production support code. No change to feature set or operating functions. V3.3   Sep 2006   [Standard Single Channel Version] Now uses the new V4.0 file system which is compatible with all previous and current AntiLog releases. V4.0 file system is more interoperable when using a multicard media reader on a PC with applications such as AntiLogReader. Improved V4.0 media recovery function now built into V3.3 to allow media recovery from data recorded from any current AntiLog unit. Visual feedback when playback and record mode start even if LEDs are disabled (single flash of red or green to show unit has indeed started). Visual feedback when two button erase has been actioned (yellow flash). 'About' menu name changes for compatibility with V4.0 (e.g. 7BitTStamp -> AscTStamp). LEDs flash yellow following valid time and date entry. This gives a visual feedback that a time transfer to this unit has taken place. Playback session number can now go higher than 65535. 'Percentage full' indication on main menu now relates to how full the media really is. Before it compared the number of bytes written to the media capacity which did not take into account overheads such as time stamp storage. Gap between main LED flash now reduced from 1 second to 0.8 seconds for compatibility with V4.0. V3.2   Apr 2006   [Standard Single Channel Version] 'On' button delay to start playback mode extended further from 1.0 second to 1.75 seconds. Baud reset delay extended to 10 seconds with visual feedback (yellow LED forced on) when baud reset time reached. Support for new 'L' option which prevents baud rate resets with the 'On' button if the settings lock is active. V3.1e   Jan 2006 Improved shutdown in case of low battery condition ensuring even more robust data collection. New Line Triggered real time playback feature using primary serial port Rx line. Data can now be replayed on demand from an external 1 pulse per second source for example. Support for the new Forced Power On ('P') hardware option. V3.1d   Jul 2005 New time transfer mode to accurately transfer time and date to any other AntiLog unit running V3.0+. Fixed a problem with the two button erase function not always working at start up. Delay to get playback mode at switch on extended from 500mS to 1000mS (user feedback request). Sub sample "starts with" string can now contain space characters. "ASCII End Of Line Character Selection" menu now shows <CR><LF> for clarification. Parity and extra stop bit generation now available in recording mode. Hexadecimal playback now prints out partial lines with small numbers of recorded bytes. User defined baud rates have been re-worked and can now operate below 300 baud. V3.1c   Mar 2005 Fixed a midnight roll-over problem introduced into V3.1 code which could cause the unit to lock up at midnight under certain conditions. V3.1b   Mar 2005 Fixed 'time valid' flag in Session Header. Flag was sometimes saying session time was not valid ('R' - relative time) when the time and date stamps were valid. Attempting to play back data with no media card present was sometimes producing a string of binary zeros. Now fixed - a 'No media present' warning is issued and no output is produced. V3.1   Jan 2005 Major speed increase. Data capture now possible at full rate 460,800 baud. Media read/write code upgrade. (Backward compatible with V3.0) Session header now shows serial number of AntiLog unit used to record the session data. Faster and improved data recovery feature. Time tagging of data now down to 1mS resolution (was 5mS). Fixed unwanted delay in selecting record mode from 'On' button on units without RTC option. V3.0c   Nov 2004 User baud rate error now displayed correctly for negative errors. Baud rate changes that effect the current menu baud rate are now more intelligently handled. V3.0b   Oct 2004 Up to 20% improvement in playback performance for X-Modem uploads compared to V3.0 Two button erase now works with slower media and when holding the 'Off' button after releasing the 'On' button. Fixed problem where battery check could cause baud rate to change in dual serial port mode where playback and menu baud rates were different. V3.0-M   Aug 2004 Message ID numbers are no longer specified from a fixed table of values. User can now define and later select from up to eight message ID numbers for automated connection. Now compatible with more GPS receiver types. More efficient message connect algorithm which works even if no message data is currently being transmitted by the receiver. V3.0   Aug 2004 Dual serial port support for hardware REV C and later. This allows for example, all data to be recorded from one port while the menu system and playback appear on another. In many setups, this removes the need for cable swapping when trying to upload recorded data. Serial port settings now include support for 5 to 8 data bits, parity and stop bits. The menu system port settings can now be independent of the record and playback port settings. Non standard baud rates can now be entered and selected for any of the record, playback and menu port settings. ASCII line data can now be time and date stamped in record mode to 5mS resolution with only a six byte per line overhead. Time stamps can be embedded into playback data stream as an ASCII string. The dates in the menu system and embedded time stamp output can be selected from dd/mm/yyyy or dd-mmm-yyyy format. Playback can now use the time stamp data to provide the timebase for 'real time' playback. File system upgraded to support multiple sessions. File system can read and recover data written by all previous software releases. Session headers can now be embedded in playback data stream. User configured sub sampling of ASCII line data in record mode. Both line and frames of lines can be sub sampled. Recorded data can be played back as a hexadecimal and ASCII dump for equipment output analysis. User command can now be issued continuously at a user defined rate. New Automatic Media Recovery system in case all sources of power are lost during record. Media 'hot swap' now supported (main menu for example, automatically updates when media inserted or removed). ASCII end of line character for record can now be selected as Line Feed or Carriage Return. New 'Menu quite' feature to suppress initial menu output if this would cause problems to any equipment connected ready to receive data in playback mode. AntiLog Real Time Clock (RTC) hardware now supported. All time stamps are then related to the real time and date. About menu option now gives a summary of all major port settings. New 'Record Data Now' item in the 'Recording Options' menu to allow recording mode to be selected directly from the playback menu system. Main menu now reports the number of sessions used to make up the data currently recorded in the flash store. Response to 'Off' button corrected to allow AntiLog to shutdown properly when the menu system is continuously flooded with random input data. V2.0-M   Dec 2003 AntiLog-M option for military GPS receiver testing using ICD-GPS-150 and ICD-GPS-153 compatible data streams transmitted via RS232. AntiLog-M option compatible with GPS receivers such as SPGR, PLGR, DAGR, GRAM, etc. AntiLog-M option can automatically connect selected ICD-GPS-15x messages if they are not already being transmitted by user equipment. AntiLog-M option provides real time playback of recorded ICD-GPS-15x data to simulate real receiver output (similar to the NMEA real time playback mode). V2.0   Dec 2003 New NMEA message filtering option which allows you to select which NMEA sentences are to be logged from the incoming data stream. This option can considerably reduce the storage and data processing requirements associated with GPS trials data. A user defined equipment command can now be issued each time the 'On' button is pressed during record. This gives the user the ability to reset user equipment or initiate equipment readings during a trial. Two separate types of user events can be written to the log file in response to 'On' and 'Off' button presses during record allowing the user to mark significant events during trials activities. Each button push has its own independent sequence number which gets written to the log file. Can now record full rate 230,400 baud data. New embedded system bootloader to allow software upgrades to be applied simply by sending a distributed file to the AntiLog serial port. Keypress response improved with new de-bounce mechanism for all button events. Further enhanced X-Modem playback performance. V1.3b   Oct 2003 Both LEDs now flash briefly to give visual confirmation that holding the 'Off' button has powered the unit down successfully. V1.3   Jul 2003 Reduced power consumption. Can now dynamically reduce system power consumption even further when using selected baud rates less than 115,200. X-Modem transfers can be aborted cleanly whilst in the middle of a transfer. Battery condition check can now be aborted before completion. Pressing the 'On' button during playback mode produces a cleaner start to the playback of recorded data (switch de-bounce improved). 'About' playback menu now reports board revision code. V1.2   May 2003 User can now 'Lock' the menu system to prevent unintentional corruption of settings caused by powering the unit up in playback mode rather than the intended recording mode with a live data feed. New battery check option with terminal voltage report. Two button media erase now always comes up in playback mode and requires the user to hold both buttons for at least one second before erasing media. Playback baud rate menus is now 'On' button and X-Modem aware. Media code improved allowing the use of slower performance MMC cards if required. V1.1   April 2003 Improved serial port code to allow sustained 115,200 baud rate recording. Main menu now reports media storage capacity in available bytes rather than media size in MBytes. Switching between playback baud rates in playback mode no longer produces a spurious character on the serial port. V1.0   March 2003 First release.
