There are various option packs available to further extend the
feature set in AntiLog or AntiLogPro units. There are two types of
option pack available:-
Hardware option packs can only be requested and fitted at manufacture.
For example, a unit that is not configured with the Forced Power (P
option) cannot be later upgraded with this feature using software.
Software option packs can be requested at purchase and can be added
after purchase without having to return the unit to the point of
If you wish to upgrade your unit with an option pack after
purchase, you can obtain a special upgrade text file from your AntiLog
supplier that can be sent out in electronic form. This upgrade file
is then simply transmitted to your unit while the unit is in the
playback menu system. You can use any standard serial port terminal
program to send the file or our dedicated AntiTermPro application.
The following table lists the current options available for AntiLog
and AntiLogPro units. The title in the main AntiLog menu system shows
what options are currently installed in a given unit.
Starts recording as soon as power is applied (no need to push
GNSS Simulated Receiver Output
Simulate up to two channels of GNSS (Global Navigation Satellite
System) receiver output at user defined fixed positions whilst
logging up to two channels of data in record mode at the same
Allows a password to be set to prevent unauthorised access to
the menu system to alter configured settings.
Extended 'On' button push
Extends the amount of time required to push and hold the 'On'
button to start the unit in the playback menu system. Often
used in medical applications.
Option 'P' - Forced power
This hardware modification allows an AntiLog or AntiLogPro unit
to start logging data as soon as power is applied without the need
to press any buttons. Logging stops when power is removed. Data is
always appended to the store each time power is applied so no
existing recorded data will be lost.
Pushing and holding the 'On' button for two or more seconds
whilst power is applied will place the unit in the playback menu
system instead of record mode so you can play back the data or
change the unit's settings.
This option is available at purchase for OEM units only. It is
designed for power sources in the range 9.5 to 18V (e.g.
All AntiLogPro OEM units come with this option fitted as standard
and this is the recommended option for all AntiLogPro OEM units used
in a multiple unit configuration.
This software option can simulate up to two independent channels
of GNSS (Global Navigation Satellite System) receiver output at user
defined fixed positions, whilst logging serial port data on up to
two channels simultaneously in record mode. Selectable NMEA
messages are transmitted during a recording session with the current
time and date embedded in the output message stream.
This option can simulate signals from GPS, GLONASS, Galileo,
BeiDou and integrated navigation signal sources independently per
logging channel. For each channel, you can enable and disable
individual NMEA sentences as required and you can even combine this
recording mode with the existing user defined polling mechanism to
periodically output user defined message content in any format as a
part of the simulation.
AntiLogPro OEM units also transmit a dedicated one pulse per
second (1PPS) output on the J3 pin header to simulate a real GNSS
1PPS signal output for timing purposes.
Combining this option with all of the existing AntiLog
capabilities provides an extremely flexible and competent total
logging solution. As an example, the following diagram shows the
logging data flow options for an AntiLogPro OEM unit with the G
option installed and an external environment sensor connected to the
J3 pin header.
Option '1' - Power from the 9-way D type connector, pin 1
During manufacture, AntiLogPro units can be configured to receive
power from pin 1 of the main 9-way D type RS232 serial port connector
(J2). This hardware modification is called Option '1'. It can
greatly simplify the installation of an RS232 data logger in a
custom configuration as only one connector and cable are required to
realise a complete data logging solution.
You are still able to supply power from the standard power input
sources if you need to (e.g. from the DC barrel connector, or PP3
clip where fitted).
Option 'M' - Government and military GPS receiver extension
This option allows easy capture and replay of ICD-GPS-153,
ICD-GPS-150 and similar (ICD-GPS-15x) Government and Military data
The 'M' option provides the following capabilities:-
Includes all standard functions available in AntiLog.
ICD-GPS-150, ICD-GPS-153 (ICD-GPS-15x) data stream
Message 'autoconnect' feature to automatically request up to 8
user defined message IDs.
Automatically sends out acknowledgements in response to
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
Selectable 'real time' playback of ICD-GPS-15x data.
Selectable time tagging of all incoming IP messages to 1ms
Button pushes (button events), digital inputs, external
environment sensor readings and supply voltage can be inserted
into the logged data stream as custom IP messages during a
Time tagging and message events implemented as intelligently
inserted custom IP messages.
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
Playback can hide (raw playback) or expand the time stamps
into the output stream.
As AntiLog 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).
Option 'S' - Security option
Allows a password to be set to prevent unauthorised access to the
menu system to alter configured settings.
When a password has been set, the user is prompted for a password
each time the unit is powered up in playback mode. If incorrect
passwords are attempted, no access will be given to the menu system
to change settings.
This option is useful in important trials activities where you do
not want a unit's configuration to be changed, even by accident
during a trial.
Option 'X' - Extended 'On' button push
Extends the time required to press and hold the 'On' button to
allow the unit to start up in the playback menu mode. Normally, you
press and hold the 'On' button for around two seconds or more to
start a unit in the playback menu mode, but this option extends that
time to five seconds.
This is useful for example in medical applications where staff
are used to having to hold on to power and other buttons for a
second or so to prevent accidental activation which could lead to
serious problems if a short knock on a button powered equipment on
A user in this environment might want to start a logging session
on their AntiLog datalogger and might push and hold the 'On' button
for around two seconds to get it started which would put the unit in
playback, not record mode. Extending the time to five seconds
ensures the user in this environment really did mean to enter the
playback menu mode.
