Overview The LX series instrumentation data recorders can record and reproduce signals of a maximum 48 kHz
sampling frequency via 8 channels onto MO (Magneto Optical Disk) or PC card media. Recorded data on
the media is stored as PC files. The maximum input channels are 32 channels by using the selectable
types of the 8 channels input cards and the optional channel expansion unit.
You can choose the recording media among the followings: Recording to the internal memory, 3.5 inch
MO, PC card, and a PC.
The file format is TEAC's proprietary TAFFmat format. TAFFmat files can be loaded into commercially
available analysis software.
From a PC you can use the supplied LX Navi software to set recording conditions such as the input range
or sampling frequency. The interface with a PC is hot-pluggable and compatible with IEEE 1394, so after
setup you can disconnect the LX while the power is still on, and start or stop recording by using control
buttons on the main unit. You can also use LX Navi to record or reproduce while connected to a PC.
You can chose the 100BASE-TX Ethernet interface as alternative.
An optional color LCD remote control unit is available to set recording conditions, to record and reproduce,
and to monitor by using bar meters.

Order of recorded data
About TAFFmat
TAFFmat (an acronym for Teac Data Acquisition File Format) is a file format composed of the following:
za data file containing A/D (analog to digital) converted data. The file is in binary format with the
extension dat.
za header file containing information such as recording conditions. The file is in text format with the
extension hdr.
This document uses the term ID to refer to a collection of data collected from the start of recording on the LX
series until the recording is stopped or paused. For each ID, one data file and one header file is recorded.
A voice memo is recorded as a WAV file with the extension wav.
The above files share a common file name, to which is appended an ID number. When a new file name is
specified, this ID number becomes 1. Each time recording starts, this number is incremented by 1.
A/D-converted data is recorded as 2-byte integers from -32768 to +32767. Negative numbers are
expressed as complements of 2. The byte order is from the lower bytes to the higher bytes. The data order
is as follows: first sampling channel order -> second sampling channel order ->...-> last sampling channel
order. At the LX series, ADC value +/- 25000 represents +/- 100 % of the input range.
This document uses the term scan to refer to a collection of data resulting from one sampling. A data file is
a collection of scan repetitions.
Example:
Data of 1 scan when the sampling frequency is 6 kHz:
Standby
REC Start FWD Pause PAUSE Resume FWD Stop STOP

Notes on Usage
zUse of a UPS is Recommended
We recommend that you use a UPS (Uninterruptible Power Supply) whenever you use an AC adapter.
This can protect important data during a power stoppage. If power is turned off while a media is in
a drive, data recorded on that media might become unreadable. Use an optional battery unit to
back up the operation at the power stoppage.
zUse Specified Media Only
Use 1.3 GB, 3.5 inch MO disks from Fujitsu Ltd.
Use PC cards checked by TEAC in advance (contact us for information).
Other media might be unable to record or reproduce correctly.

zRemove Media Before Powering Off the LX
Remove the media before you power off the LX. If you power off the LX while data is being written,
data recorded on that media might become unreadable. Also, remove the media before moving the
LX main unit. Moving the unit while the media is inserted might result in damage, in particular on a
MO disk.
zRemove Media
Remove the media only at the STOP state of the REC mode.
zNever Remove Recorded File, Never Rename File/Folder Name of Recorded File By Windows
Operation
If you manipulate the recorded files on the media by Windows operation, such as partially removing
the file, or renaming the file/folder name, the link between the data file and the header file will be
lost or the writing speed to the media to support the specifications cannot be assured, and then the
data will become unreadable on the PC when such media is re-inserted in the LX.
Write-protect an MO disk before inserting it into a PC drive.

Notes on Usage
1-7
zClean Disk and Lens
Dust might collect on an MO disk or lens after they have been used for a long time. This dust might cause
errors. To prevent this problem, clean the MO disk and lens using a cleaning kit (separate purchase). The
period after which cleaning is required depends on the environment but, as a general rule, clean once every
three months.
9To clean an MO disk, use the cleaning kit TZ-381 (separate purchase). To clean a lens, use the lens
cleaner 0240470 (separate purchase).
9For details on how to clean, see the explanation supplied with the cleaning kit.
zHandling PC Card
To discharge static electricity from your body, touch a metallic surface near you before handling the unit.
Never touch the media being inserted to the PC card slot while recording and playing back.
zMake Sure to Select FAT16 When Formatting Media by Windows Operation
The LX file format does not support FAT32, use FAT16 format before using.
