For data recording systems, the GX-1

Fast Collection of Valuable Data
The GX-1 Integrated Recorder is a compact, A4-size, data recording system with a signal conditioner configuration. Now you can accelerate the recording and transfer of valuable data from data-acquisition sites to data processing and analysis groups. With the goal of decreasing various data-recording overheads, the GX-1 provides an integrated solution in a single system: integrating such functions as connecting sensors, recording data, viewing recorded data on site, and transferring data to high-level processing and analysis systems. To let you use the GX-1 from the day it is installed, we supply the GX Navi software, which provides unified control of sensing, calibration, data recording, monitoring, and transfer of data to PC.

Connecting
Input/output components using card slots

You can select from a wide range of input/output cards that can be inserted into the main unit. For example: input amp cards that enable direct input with DC, acceleration sensors, strain gages, measuring microphones, thermocouples, etc. with 16-bit A/D converters built into each channel; analog output amp cards with built-in 16-bit D/A converters; digital input/output.

Each input/output card has 2 channels, with 8 slots in the main unit giving 16 channels, If you need more channels, by using an expansion unit that has the same size as the main unit, you can build a recording system that has a maximum of 64 channels.

Recording
1 machine, 2 roles: An A/D converter with a built-in signal conditioner, or a data recorder with a choice of recording media

You can record directly to a PC connected via the main-unit’s SCSI interface, with the main unit acting as the front end for measuring. In addition to recording to memory, you can record onto 3 types of removable media that can be accessed directly from a PC drive: MO (magneto-optical) disks, AlT (Advanced Intelligent Tape) cassettes, and PC cards. You can choose the recording medium that best suits your needs: for example, recording low-speed phenomena over a long period, or recording high-speed phenomena that occur intermittently.

Transferring
Save recorded data in the convenient TAFFmat format for data processing on a PC

Recorded data is saved in the TAFFmat (TEAC Data Acquisition File Format) format. TAFFmat files combine binary data files with header tiles that contain the input/output amp card settings and recording conditions. One binary data file and one header file are produced each time a recording is saved. You can transfer data via the SCSI interface on the main unit, or use a PC’s drive to read data that the GX-1 recorded onto an MO disk, tape, or PC card.

Viewing
Real-time monitoring—great for on-site checking of data

If you connect to a notebook computer, in addition to setting signal conditioner parameters and controlling recording behavior, you can monitor and display in real-time, and switch among waveform, bar graph, and PET windows. In addition, for environments where a PC cannot be used, or for experiments in vehicles, a dedicated LCD controller can provide realtime monitoring. (This controller is for use in systems that use the AIT, MO disk, or PC card media for recording.)

Convenient features from earlier data recorders are preserved

The main unit contains the channel parts required for analog output amp cards, so you can perform analog playback of data recorded onto some media. Also, you can still record and play back voice memos, which enables you to use the GX-1 in the same way as earlier data recorders.

3 power sources for reliable recording in the field

You can select from a DC power source (11 to 30 V), internal AC power pack, or a built-in battery pack. Using a combination of DC and an AC power pack, or DC and a battery pack, provides power backup for redundant operation.

Connecting
Combine our wide selection of input/output amp cards, and build a system of up to 64 channels!

You can select the input/output amp card that best matches what you want to measure. Each input/output amp card contains 2 channels. The GX-1 main unit has 8 slots and 16 channels, and you can add up to three 8 -slot AU-GXEPIO expansion units, to provide a system with a maximum of 64 channels.

Recording
Transfer to a PC in real time, or record directly to various media

You can transfer and record data directly to a PC connected via the main-unit’s SCSI interface. Or, you can record data onto a recording medium in the main unit, and then send the data to the PC. Or, you can first record the data onto media such as an MO disk, AIT cartridge, or PC card, and then insert this media into a PC drive for reading. You can select the method that best suits your experimental environment, goals, the frequency bandwidth of what you want to measure, and the required recordjng time.

In the real-time mode, useable sampling frequency and the length of the recording time may vary depending on the data processing speed at the PC. When recording to a recording medium, maximum recording transfer rates differ with the medium, as shown in the following table. However, the maximum sampling frequency of the built-in input/output card is the upper limit.

Recording times (at maximum transmission rate) depending on the type of media and the sampling frequency (Up to 32 channels) -

(From 33 to 64 channels)
Media (recording capacity) Sampling frequency x Recording time (at
number of channels (at maximum transmission
maximum) rate)

Memory (when 256 MB) 2500 k (50 k x 50 cli etc.) Approx. 50 sec.
AlT (25 GB) 1200 k (20 k x 60 ch etc.) Max. of approx. 170 mm.
MO (1.3 GB) 200 k (20 k x l0ch etc.) Max. of approx. 50 min.
Real-time transfer 1200 Ic (20 k x 60 ch etc.) Depends on the type of
media at the PC

External sampling
You can record by synchronizing with an external sampling frequency up to the maximum sampling frequency of a built-in input amp card. Perform data processing on the recorded data as a file.

Multi-sampling
When sampling is based on an internal clock, you can set a sampling frequency that is different for each input card. (However, the maximum value of the sampling frequency set for each input card must be within 10 times of the minimum value.) When fast and slow phenomena coexist, multi-sampling enables efficient recording.

Recording by trigger conditions
You can use the supplied GX Navi software to set recording intervals based on pre-triggers, post-triggers, level triggers, repeat recordings, or times. You can also record by using a combination of these trigger conditions.

Recording voice memos
When recording voice memos, you can record to internal memory or an AIT.cartridge as one channel." To convert a recorded voice memo to a WAV file and listen to the file, you can download a free Windows PC utility from the TEAC home page. You can also record a voice memo as a WAV file onto an MO disk, to internal memory, or onto a PC card. You can use the Windows media player to listen to such voice-memo WAV files.

Two types of remote control units
Two types of remote control units can be connected to the GX-1 main unit.

• DK-GXLCD: Remote control unit with LCD

This control unit with a 640 x 480 pixel LCD color display is very convenient in environments where you cannot use a PC. In addition to enabling you to set recording parameters, start and specify settings for recordings, and attach event marks to data, this remote control unit has the same display functions as a PC screen used for real-time monitoring during recording.

• ER-GXRC: Handy remote control unit

After using a PC to specify settings, you can use this remote control unit to start and stop recording, and to attach event marks to data.

The optional CL-GXRC cable is available for using external controllers in the same way as for this handy remote control unit: connections use the remote control unit connector. The ER-GXRC can also be used with a PC.

KH-2ST battery charger for the internal battery HP-30A
The internal battery can operate for more than 40 minutes at a sampling frequency of 50 kHz in a configuration with an AIT drive, DC input amp card, and 16 channels. When the main unit is working off DC power, this battery will maintain operation if power fails. Use the dedicated charger to recharge the internal battery.

1. To record a voice clearly, set the sampling frequency for the built-in input module to 5 kHz or higher.
2. A power source exclusively for this unit is required. (An AC adapter and a DC input terminal are provided. When using a battery, request the TZ-GX DKM tilting table and the HP-30A battery pack.)
3. You cannot confirm settings, or perform monitoring during recording, etc.

Viewing

Use multiple windows for real-time checking of data recorded over multiple channels
By using PC windows or the DK-GXLCD remote control unit with an LCD, you can perform real-time monitoring of data during recording. Also, you can check data after sensor calibration, and perform an on-site review of data after a recording. By switching among time-series waveforms, PET, and parameter windows, and by displaying multiple channels simultaneously, you can reduce the costs and labor required to carry oscilloscopes and FF1’ analyzers to a site. When a PC is connected via a SCSI interface to the OX-i main unit, you can use the supplied GX Navi software to achieve real-time monitoring.

Waveform display window
You can display selected channels (up to 16) in a single window. Also, you can set the channels being monitored by increasing the number of displayed pages, and by switching among each displayed page. When displaying data after recording to memory, you can perform operations such as reading data by using the cursor line, scrolling the display, or zooming into a specified range of a waveform.

• With sampling frequencies that exceed 50 kHz, there are limitations on the monitoring display functions when recording or playing back.
• When monitoring during recording based on external sampling, there are limitations on separate displays.
• When using the AR-GXAO analog output amp, the playback display shows the waveform display only.
• When using the remote control unit DK-GXLCD with the LCD, the playback display shows the waveform display only.

FFT window
You can show FFT displays of selected channels (up to 16) in a single window. Selectable items include linear scale or log scale, peak hold, average-value display, and window functions.

Bar graph display window
You can show all channels in one window. This window includes a peak-hold function. When a set range is exceeded, an overload indicator function displays the problem in red.

Use the GX View program to check data Immediately after recording
The GX View program is a utility for playing back recorded data in a PC window. You can use a PC to read data that was recorded on an AIT cartridge, and have multiple waveform displays of channel data, or X-Y displays of selected channels. Part of a waveform can be cut, and that part can be converted to a file: for example, into ASCII data. To enable data files recorded by GX-1 to be read by commercially available programs that specialize in analysis of measurement data, we have a library of file converters for various file formats.

Transferring

Perform fast PC-based data processing and analysis
Recorded data is saved in the TAFFmat (TEAC Data Acquisition File Format) format common to the TEAC digital data recorders. Because recorded data can be processed directly on a PC, you can expect fast analysis of experiment data. Also, an analog output card is available for cases that require playback of analog signals.

Transfer recorded data from the GX-1 main unit to a PC
Using the supplied GX Navi software, you can copy data files (recorded to memory, or onto an AIT cartridge, MO disk, or PC card) to the hard disk of a PC connected via a SCSI interface.

Read directly from media inserted into a PC drive
After using a GX-1 to record data onto an AIT cartridge, you can insert the cartridge into a PC drive and (at the PC) use the GX-View utility to directly read the recorded data files from the tape. Similarly, when data is recorded onto a MO disk or PC card, you can directly read the recorded files after inserting the disk or card into a PC drive.
