There are various option packs available to further extend the feature
set in AntiLog or AntiLogPro units. There are two types of option
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 sale.
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
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.
AL=AntiLog, Pro=AntiLogPro, H/W=Hardware option, S/W=Software option
Starts recording as soon as power is applied (no need to push any buttons).
Government and Military GPS Receiver Extension
ICD-GPS-150, ICD-GPS-153 (ICD-GPS-15x) data stream
compatibility for both record and playback modes.
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 time.
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
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
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. automotive).
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.
Option 'G' - GNSS simulated receiver output [AntiLogPro only]
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 '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 streams.
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 compatible.
- Message 'autoconnect' feature to automatically request up to 8 user
defined message IDs.
- Automatically sends out acknowledgements in response to acknowledge
- 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
- 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 trial.
- 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 data.
- 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
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
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 or off.
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.
