For a more complete description of AntiLog's capabilities, please take time to view the following product information sheets for the two current AntiLog embedded software releases:-

Simply push the 'On' button to start AntiLog recording your serial port data. Hold the 'Off' button down to stop a data logging session and switch the unit off. Simply switch on and off like this to continue RS232 data logging as you require, data will be appended to the store - it's as easy as that!

You hold the 'On' button down for more than a second to put the unit in playback mode. In this mode, you can configure the system to your needs. A menu system appears which you can view and operate using any serial port terminal application. With this menu system you define exactly how AntiLog handles data recording and playback. This is how you set recording and playback serial port settings, recording and playback modes (e.g. 'real time') and all other options.

While in playback mode, simply push the 'On' and 'Off' buttons as many times as you want to start and stop data replay. You hold the 'Off' button down for more than a second to switch the unit off as before.

You are not restricted to playing back data at the same baud rate it was recorded. You can also optionally embed recorded time tag information in playback data streams. All settings are non-volatile so you only have to set them once even if all sources of power are removed.

There is also no need to transport an enormous power source around with you because instead of consuming hundreds of milliwatts or more of power, AntiLog can record RS232 data happily for days on a single PP3 battery. As an example, AntiLog uses typically just 80mW (including media power consumption) to record full rate continuous binary data at 115200 baud. AntiLog has the ability to dynamically reduce power consumption based on baud rates in use less than 115,200. This means AntiLog is ideal for recording GPS NMEA receiver data which is generally transmitted at a rate significantly less than 115,200 baud.

AntiLog V5.2 can further reduces power consumption if no RS232 data is being received or transmitted. This can result in up to a further 25% power saving in trials situations compared to the standard V3.7 release.

All boxed versions of AntiLog come complete with all you need to get you started. You get an RS232 NULL modem cable (to allow you to connect AntiLog to a PC or equivalent to upload recorded data), a printed manual, an Alkaline PP3 battery - and you even get a soft zip-up carry case!

If the equipment you wish to log data from has a serial port connection designed to fit into a standard PC, simply plug this instead into AntiLog and you are ready to record the output from the equipment. You may even record more data from your equipment than you did before with a PC RS232 data logging program because the standard serial port on a PC will miss data every once in a while, especially if a Microsoft Operating System is in use and the equipment baud rate is above 19200.

All AntiLog units now come as standard with an embedded software bootloader which means you can now receive software upgrades via the Internet.

For most data logging applications you will only need to record RS232 data from a single equipment source (e.g. a GPS receiver). Our current AntiLog V3.7 release offers high speed data capture (up to full rate 460,800 baud) from a single serial port. AntiLog V3.7 offers a very comprehensive set of features to allow you to capture and replay data the way you want it.

The new AntiLog V5.2 release offers menu options to log and playback up to two RS232 data sources at the same time. It's just like having two V3 AntiLogs in a single box! The RTS/CTS lines on the AntiLog serial port connector become the second serial port. You can configure each port for completely independent operation (e.g. different baud rates, filtering, time stamping options, etc). Each port supports it's own equipment polling and it's response to button pushes during a recording session.

Not only is it possible to record from two channels simultaneously, but you can play back two recorded sets of channel data at the same time, even in real time! V5.2 also offers saving and retrieving of complete sets of user options to a named store to allow almost instant reconfiguration of your units for different trials applications. This is particularly useful if you share a unit between applications as you can recall a complete configuration using a single menu option.

If you record two channels of RS232 data using the one AntiLog unit, the two data streams also share a common time stamping reference which can be ideal for later data analysis.

The fully boxed product comes ready to use. Use our OEM module to embed a high quality, single board, RS232 data logging solution into your own product. The OEM module is built to last in demanding situations. It uses robust surface mount construction and measures only 50mm x 60mm. It is functionally identical to our boxed product but it allows direct access to the removable FLASH media (socket mounted under the card) and allows direct access to CMOS RS232 levels.

The OEM board only requires the addition of a power source, two push to make switches ('On' and 'Off' buttons) and one bi-colour LED to realise a complete RS232 data logging solution. You can use the standard 2.54mm pitch, 2x8 pin header to interface directly to your application. The pin header for example, allows direct connection with OEM equipment (e.g. OEM GPS receivers) which require RS232 signal connections at CMOS levels.

For completely unattended use, we offer a Forced Power hardware option (the 'P' option). With this option, you simply apply power to start data logging and remove power to stop logging. Apply and remove the power as much as you want to append data to the store. This option is ideal in applications where user interaction is not practical such as in vehicle installations, Unmanned Aerial Vehicles (UAVs) or process control systems in hostile environments.

There are various Option Packs available to further extend the features in AntiLog. One of these Option Packs is the 'M' option which allows easy capture and replay of ICD-GPS-153, ICD-GPS-150 and similar (ICD-GPS-15x) Government and Military data streams. The 'M' option provides the following capabilities for the V3.7 and V5.2 releases:-

• Includes all standard functions available in AntiLog.
• ICD-GPS-150, ICD-GPS-153 (ICD-GPS-15x) data stream compatible.
• Message 'autoconnect' feature to automatically request up to 8 user defined message IDs.
• Automatically sends out acknowledgements in response to acknowledge requests.
• LED flash sequence in record mode to show when checksum validated messages are being received.
• Compatible with RS232 output from SPGR, PLGR, DAGR and similar GPS receivers.
• Selectable 'real time' playback of ICD-GPS-15x data.

Additionally, the 'M' option under AntiLog V5.2 also provides the following capabilities:-

• Selectable time tagging of all incoming IP messages to 1ms resolution.
• Button pushes (button events) can be inserted into data stream as IP messages during a trial.
• User defined equipment commands can be issued by button pushes and/or at a user defined repeat period.
• Real time playback can make use of any time tags in the logged data.
• Playback can hide (raw playback) or expand the time stamps into the output stream.
• Time tagging and message events implemented as intelligently inserted custom IP messages.

As AntiLog V5.2 can log two independent channels of data, you can for example log two channels of time stamped ICD-GPS-153 data at the same time with individual messaging requirements, or for example, one channel of ICD-GPS-153 data and one channel of filtered NMEA (both with or without time stamping enabled of course).
