The following is a summary of the frequently asked questions about product applications and specifications.

GX-1 | Disk / Card Data Recorder
DAT Data Recorder | Various Software

GX-1

How does GX-1 differ from the conventional data recorder?: It comes with a built in signal conditioner (sensor amplifier) and it greatly differs from conventional data recorders in the fact that sensors can be directly connected. The direct input of an acceleration pickup, thermocouple, microphone for noise, etc is also possible.

Although there are very few screens or buttons on the main unit, how do I control the GX-1?: Using a SCSI interface, the GX-1 can be controlled using an external PC or specialized LCD remote controller. It cannot be operated independently. Windows application software is included standard.

How do I perform calibration, zero balance, etc.?: Calibration and zero balance can be performed by using the attached application.
A calibration menu is provided in the program, and calibration and zero balance can be performed on all amplifiers.

How does the GX-1 perform conversion of physical values?: It can be performed by using the attached application. The software allows for the conversion setup of physical values as well as calibration. For example, in the case of a dynamic distortion amplifier with the distortion value set at 1000ust, and the acceleration at 9.8m/s2, conversion is performed according to these conditions, and the conversion coefficient is recorded on files.

What are the functions of D/A output?: In order to perform D/A output of recorded data, an analog voltage output card (AR-GXAO) is required (like other signal conditioners it supports 2ch/slot). It is possible to perform the voltage output of the recorded signal in real time or to replay the data file after measurement

Please explain about the AIT drive, which can be installed into the GX-1: AIT stands for Advanced Intelligent Tape. It is a type of data storage that uses an advanced ME tape, designed by SONY Corp. The drive, which can be installed to the GX-1, is of the AIT-1 standard, and has an un-compressed capacity of 25GB.

Is it possible to read data recorded on the AIT tape on other AIT drives instead of the GX-1 main unit?: It is possible. Data can be read into the GX-1 from an AIT drive using the attached application. Carrying only the tape, which the data from the field has been recorded onto, it is possible to read data from an AIT drive that is connected to a PC

Is it possible to read MO data recorded by GX-1 on a Mac?: Since an MO disk recorded on the GX-1 is of the Windows format, DOS mounter is needed to read MO's on a MAC.

Am I able to use any brand of SCSI card?: No. Because of the DLL used, customers are limited to Adaptec Inc product. Be sure to only use Adaptec.

A disk / card data recorder

< PC card recorder DR-C1>

What is the maximum number of channels for recording?: 16ch ( =2ch/card x 8 slot) are available. Moreover, if you use an optional synchronous recording unit, a maximum of five sets (80ch) of synchronous recording are possible. With the operation button of DR-C1 used as a master machine, two or more sets of connected DR-C1 (slave) can be operated collectively.

How many kinds of sampling frequency parameter settings does the DR-C1 support?: There are 15 kinds of setup of either 1, 2, or 5 steps, with a sampling frequency from 1Hz to 40kHz. Moreover, the highest sampling frequency, which can be set, is determined by the number of channels used.
No of channels used x highest sampling frequency <=40kHz
Sampling frequency (All the channels used simultaneously) =
a maximum of 2kHz

How long is the recording time of the DR-C1?

The possible recording time of one PC card varies according to the number of channels used and the setting value of sampling frequency.

Continuous recording time (unit is second) =
capacity of PC card / (number of channels used x sampling frequency x 2 bytes).

<Example> In case of 16 channels and 40MB card:

Sampling	1KHz	100Hz	10Hz
Continuous recording time (standard)	21 minutes around	3.5hours around	35 hour

How can recorded data be processed?: Since PC cards are removable media, the data can be input to a PC swiftly and processed by your application software on the spot.
What's more, a data file can be downloaded to a computer in real-time via a SCSI. In such cases it is more convenient to use a waveform display program. Moreover, a waveform display is also possible after the conversion of physical quantity using a calibration program.

How is recorded data filed?

On a PC card, two files with two kinds of extension are generated as follows.

Header file: ASCII format (text) recording conditions, data counts, time, etc, are recorded.
It is compatible with the header file DADiSP format.
Data file: A file, on which signal data recorded in binary format saved according to the order of channel or scan (internal format: 2bytes integer).

< PC card recorder DR-C2 >

How many kinds of sampling frequency parameter settings does DR-C2 support?: A setup of 6 kinds of either 1, 2, or 5 steps is possible with a sampling frequency from 100Hz to 5kHz. The DR-C2 uses A/D conversion of 16-bits.

¦ Be careful of aliasing (cuff phenomenon). Theoretically, the frequency characteristic must be 1/2 or less than the sampling frequency. There is no input filter in the main unit.

How long is the recording time of DR-C2?

The possible recording time of one PC card varies according to the number of channels used and the setting value of sampling frequency.

Continuous recording time (unit is second) =
capacity of PC card / (number of used channels x sampling frequency x 2 bytes).

<Example> In case of 8 channels and a 40MB card, right after formatting, and without 1file Mark/Pause:

Sampling frequency	1KHz	500Hz	100Hz
Continuous recording time (reference)	43 min. around	1hour 27min. around	7hours 15min.

How should I perform recording conditions parameter settings?: For the setting of recording conditions, the DR-C2 supports two methods. The first is to send an ASCII condition file to a connected PC via RS-232C, and the second is to read a condition file, which has been pre-recorded on a PC card.
This can be done using the attached recording condition setting program. Pre recording level adjustment and monitoring can also be set using this software. (However, real-time monitoring is not available while recording.)

How is recorded data filed?

On a PC card, two files with two kinds of extension are generated as follows.

Header file: ASCII format (text) recording conditions, data counts, time, etc, are recorded.
It is compatible with the header file format of DADiSP.
Data file: A file to which signal data recorded in binary format and saved according to the order of channels or scans (internal format: 2bytes integer).

* If the power-supply voltage falls while recording, a warning is displayed and the file is closed.

DAT data recorder

Is it possible to use a DDS tape?: It is not possible to use a DDS tape with the RD series. Please use the recommended Maxell DM120 tapes.

Is it possible to replay a tape recorded at double speed, at same speed?: Double speed recording is possible on double-speed type data recorders (RD-125T / 135T/145T), and it can be replayed at double speed as well.
What's more, data recorded at normal speed, can be played at double speed.

Please tell me how to submit recorded data to a PC: It is possible to submit data from a data recorder such as the RD-125T / 135T/145T, and RD-120T/130T, to a computer by using the exclusive QuikVu software. With the RD-180T/200T, it is possible to submit data to a PC by using the standard GPIB interface and optional memory board (MB-400).

Is it possible to copy a recorded tape in its original digital data state?: By using the DU-100 dubbing unit, digital copying is possible. It also allows the dubbing of memo announce and lock information.

Various software

< Software QuikVuII for DAT data recorder RD series >

Why must a RAM disk be installed?: RAM disks, which allow for high-speed writing, are used as a buffer, since the HDD might have a problem with writing speed when data is being recorded.
Although the writing speed of hard disk drives have been improving recently, we are continuing to use this system in order to continue supporting low-speed HDD.

Is QuikVu-PCMCIA compatible with 32-bit bus, such as CardBus?: QuikVu-PCMCIA is definitely compatible with PCMCIA Ver2.1 to operate in 16-bit mode. Since CardBus itself is upward compatible with a PCMCIA, it can operate on CardBus slot, but it is not a 32-bit mode.

After upgrading my Notebook PC to a later model, QuikVu-PCMCIA does not work. I set it up the same way as before.: Almost all later model Notebook PC's are compatible with CardBus in PCMCIA. Such problem may occur when some PCMCIA controller chips do not recognize the QuikVu card as a 16-bit type.
In this case, since upgrading the card can solve the problem, please contact our technical support.

Does the QuikVu board support plug-and-play?: The QuikVu board does not support plug-and-play.

Is a PCI type board (non ISA type) available?: A PCI type board is not available, only an ISA type or a PCMCIA type for Notebook PC's is available.

Although it seems that it uses DOS mode, does it also operate on Windows NT?: It does not operate on Windows NT.
