1. 1 Test conditions Continuous data logging of GPS NMEA data at 4800 baud using a Duracell Plus PP3 cell and 128MByte flash media option 2 Only applies to AntiLog units supplied with Real Time Clock hardware t RTC Backup current drops to below 1uA when AntiLog is switched on New 12026 RTC hardware uses lt luA 4 The RS232 driver chips used in the AntiLog board revisions A to C are only rated for transmit at up to 140kbaud into a full 3kOhm 1000pF load Similarly the drivers for AntiLog board revisions up to F are rated to 400kbaud Performance may therefore be effected by long cable lengths Recording data at the upper baud rate of 460 800 is possible with short cable lengths even with revision C hardware Note that the standard serial port UART fitted to most PCs cannot operate at such a high speed the top baud rate available is normally limited to 115 200 5 Test conditions Continuous data logging of replayed test data at full data rate 230 400 baud single channel using a Duracell Plus PP3 cell 128MByte flash media option and a 1 8m RS232 connecting cable 6 Test conditions Continuous data logging of replayed test data on two channels simultaneously each at full data rate 115 200 baud using a Duracell Plus PP3 cell 128MByte flash media option and a 1 8m RS232 connecting cable 8 Environmentally tested extended temperature range versions available upon request DOC AntiLog UG 2003001_4 0e
2. 2 6 Playback Considerations The playback baud rates are completely independent of the baud rates you used to record the data You may select any combination of baud rate and RS232 bits per character which suite your needs However If you attempt to use a terminal program to view the AntiLog playback menu system you may see nothing if the terminal baud rate and or data bit selection is different to the currently set AntiLog menu baud rate Section 5 9 describes how to reset the menu port settings if this happens Additionally if you have hardware that supports the Dual DOC AntiLog UG 2003001 4 0e Page 8 of 71 Serial Port feature playback and or the menu system may be assigned to different hardware serial ports and so output may not be seen on the primary port Also note that if you choose to playback data with less RS232 bits per data character than the recorded data format data corruption may occur if any of the output bytes don t fit into the bits specified The safest policy is to leave the number of RS232 bits per character set to eight for playback and for the menu system unless your host equipment requires other settings 2 7 Battery Life If you are running from an internal battery always use a new one when recording important trials data To maintain the life of the battery it is recommended that it is disconnected completely from the system if AntiLog is not to be used for more than a week or so This is because AntiLog supports
