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:-
See the upgrade release history for AntiLog products here.
AntiLogPro is an advanced version of the original AntiLog
design that is available as an OEM module with dual channel data
recording as standard. It provides the following features:-
- Very high performance. Full rate recording at 921,600 baud (one channel), 460,800 baud (two channels simultaneously).
- Fully configurable RS232 line management including individual line inversion and power saving options.
- Logging of digital logic line states (inputs protected to ±40V).
- Baud rates supported: 110 to 921,600 and user defined.
- Selectable "Ring Buffer" storage method which retains the most recent data.
- Select any ports from the three hardware serial ports available for recording and playback.
- Onboard complete RTC backup solution including battery.
- GPS navigation receiver simulated output option available (simulate up to two channels of GPS NMEA for user defined locations in real time).
- Hardware 1PPS synchronization output signal for precise timing applications.

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
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
There is 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 58mW (including
media power consumption) to record full rate continuous binary data at
9,600 baud and around 90mW at 115,200 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
Single or dual channel operation
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 latest 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 modules to
embed a high quality, single board, RS232 data logging solution into
your own product. The OEM modules are built to last in demanding
situations. They use robust surface mount construction and measure
only 50mm x 60mm. The AntiLog OEM module 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
The OEM boards only require the addition of a power source, two
push to make switches ('On' and 'Off' buttons) and a bi-colour LED
(two for the AntiLogPro variant) to realise a complete RS232 data
logging solution. You can use the standard 2.54mm pitch, 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.
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 zip-up
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
Government and Military GPS receiver option
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
- 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
- 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).
