SCSI

The GX-1 is a customizable data acquisition system for measurement data; the GX-1 enables construction of a data collection system optimized to your needs. Recorded data can be saved to files for a PC in a TEAC unique format called TAFFmat, and can be opened and processed using commercially available analytical PC software.

A variety of signal conditioners can be installed as input amps, so you can forget the nightmare of setting up many amps individually and connecting the power supply for them. The GX-1 main unit contains 8 slots for input amps. Each input amp card handles 2 input channels, which enables up to 16 input channels to be recorded when all 8 input card slots are used. Furthermore, you can use optional channel expansion units to expand the number of channels up to 64 input channels.

You can choose the recording medium that best suits what you want to measure: memory, AIT (Advanced Intelligent Tape), MO, or PC card. Whichever you choose, after recording you can pass on the data to a PC via SCSI as well as record data directly to a PC's hard disk. Of course, if you choose an AIT drive, after recording you can insert the AIT cartridge into a PC's external AIT drive for data processing at the PC. Also, the data recorded on an MO or a PC card can be read by a PC’s external MO drive or PC card slot as TAFFmat files.

The GX-1 can be controlled either from a PC via SCSI using provided software (named “GX Navi”), or from a remote controller that has a color LCD (DKGXLCD). If you just want to control the recording status, a hand-held remote controller (ER-GXRC) is handy.

Overview

▼A PC cannot recognize the internal drive of a

GX-1.

▼On an AIT cartridge, the data is stored in a

TEAC unique format. However, you can use the software that comes with the GX-1 to copy the data as a TAFFmat file to a PC.

● Selectable recording medium that best matches what you record

A choice of recording media allows you to select the medium that best matches the application, like choosing memory when recording fast phenomena and choosing an AIT or MO drive when recording a great amount of data. (See the table below.) The measured data can also be recorded directly to a PC (e.g., to a hard disk) via SCSI. (We term this PC-direct mode real-time transfer. In this mode, the real-time monitoring introduced next is unavailable.)

● Real-time monitoring

Using the provided software “GX Navi”, you can monitor recorded data on a PC window as real-time waveforms or bar graphs, and you can also perform real-time FFT analyses. The waveforms of data recorded in memory or removable medium can later be displayed, and scrolled through, in a window. (Bar graph and FFT displays are possible for sampling frequencies of 50 kHz or less, and waveform displays are possible for 200 kHz or less.)

● Multi-sampling

From the internal clock frequencies, you can select a base sampling frequency and 10 times the base sampling frequency at a time. This enables you to record fast phenomena and slow phenomena at the same time besides saving storage capacity.

Available internal clock frequencies: 1, 2, 5, 10, 20, 50, 100, 200, 500 Hz, and 1, 2, 5, 10, 20, 50, 100, 200, 2.5, 12.5, and 25 kHz

Notes:

• The sampling frequencies are set slot by slot, not channel by channel.

• The total of [sampling-frequency x number-of-channels] must not exceed 3,200 kHz.

• Some commercially available analytical software cannot read the data files recorded by multi-sampling. Contact us for details.

Features

● Voice memo recording/playback

You can record and play back voice memos.

● External-clock sampling

Sampling can be performed based on an external clock signal.

● Various recording modes

· Manual start mode: Recording is started manually.

· Pre-trigger mode: Data is continuously stored so that

data from a specified time before the occurrence of the trigger can be recorded in memory.

· Post-trigger mode: Recording is started at a specified

time after the occurrence of the trigger.

· Level-trigger mode: Recording is started when a speci-

fied change occurs in the signal level of a specified channel.

· Timer mode: Recording is started at a specified

time.

● Event marks

You can attach event marks to desired points in data during recording. You can later search through the data to find attached event marks.

● Analog reproducing

Data recorded in the internal device—memory or removable medium—can be reproduced in waveform display. With the optional analog output amplifier, you can reproduce the recorded data as analog signal.

● Clock correction by IRIG-B time code

The internal clock can be corrected by an external IRIG-B time code signal.

TAFFmat is an acronym of Teac Data Acquisition File F

ormat. In the TAFFmat format, data are saved in two kinds

of files: data files that contain data through A/D conversion, and header files that contain recording information such as recording conditions. A collection of data recorded from the start until the end of each measurement by a GX-1 is referred to as an ID. Each ID is composed of one data file and one header file. Data File: A binary file containing binary-format data through A/D conversion. Each data file has the filename extension of dat. Header File: A text file (ASCII code) containing recording information such as conditions. Each header file has the filename extension of hdr.

Within the same ID, the data file and header file have the same filename, which begins with five alphanumeric characters and is followed by a three-digit ID number. The three-digit ID number is automatically set to 001 when five characters are given as a new filename. You can also specify that this number automatically increments by one whenever a recording starts.

Installing Amplifiers

CAUTION

Before attempting to install or remove a signal conditioner, turn off the power at the GX-1 main unit. If you attempt installation or removal while the power is turned on, you might damage the GX-1 main unit and the signal conditioner.

● Channel Numbers

Slots are numbered from the left (as viewed from the front of the GX-1 main unit) in the order 1, 2, 3, etc. These correspond to channels 1 and 2, channels 3 and 4, etc. The input terminal A of each signal conditioner corresponds to the smaller number of the channel numbers, and input terminal B corresponds to the next channel. For example, A of slot 3 is channel 5.

■ Installation Procedure

1. Loosen the two screws at the top and bottom of the blank

panel, and remove the panel. (You cannot remove the screws from the panel even after you loosen them.)

2. Insert the signal conditioner into the slot. Insert the lower

edge of the board into the guide rail. Holding the signal conditioner vertically, press it in firmly.

3. Tighten the two screws at the top and bottom.

This completes the installation.

● Set the parameters

The parameter settings for the GX-1 main unit are reset when you add a new signal conditioner or move a signal conditioner to another slot. So choose Setup and then Params to revise the settings for all channels.

■ Attaching Ferrite Core

The cable connected to the input connector may emit radio noise. To reduce the radio noise, attach the supplied ferrite core on the input cable.

Open the ferrite core, turn the cable around the ferrite core, and close the core. (See fig. 1.)

■ AC Adaptor

Note:

There are two types of AC adaptors: one for 100 V and one for 200 V. Confirm that the AC adaptor you use matches the power supply voltage of the power outlet.

To install the AC adaptor:

1. Confirm that the power is turned off at the GX-1 main unit:

that is, the switch is toggled down to .

2. Insert the AC adaptor into the power supply slot on the

right side of the GX-1.

3. Plug the power cable into the AC adaptor.

4. Plug the power cable into the power outlet.

Note: Backup by DC power

If +11 to 16 V DC power is supplied to the DC IN connector while using the GX-1 with an AC power supply, the DC power supply backs up in case of a failure of the AC power. However, if the supplied voltage is +16 V DC or greater, the DC power supply takes priority.

Note: Removing the AC adaptor

To remove the AC adaptor, push the eject lever beneath the power supply slot. The AC adaptor pops out with the force of a built-in spring—be careful.

WARNING

Before installing or removing the AC adaptor, disconnect the power cable from the adaptor. If the cable is left connected to the adaptor and a power outlet, the power supply voltage is applied to the output terminals of the adaptor and might cause an electric shock.

Preparing the Power Supply

■ DC Power Supply

The GX-1 can be operated on +11 to 30 V DC. To connect the DC power supply:

1. Confirm that the power is turned off at the GX-1 main unit:

that is, the switch is toggled down to .

2. Plug the DC power cable into the DC IN connector at the

rear of the GX-1.

Note: What happens when the DC supply voltage drops to +11 V or less?

The message LOW BATTERY appears on the status bar of the provided software's window. When you see this message, promptly quit recording. If data is being recorded to the GX1's memory at this time, transfer the data from memory to a removable medium or PC. When the power supply voltage further drops to +10 V or less, the GX-1 automatically shuts down.

Note: Backup by battery pack

If the battery pack is installed in the power supply slot while using the GX-1 with a DC power supply, the DC power supply and battery pack are used in parallel. This way of use is recommended when the DC power supply is unstable. Also in this case, if the supply voltage drops to +10 V or less, the GX-1 automatically shuts down. However, since an idling current flows even during shutdown, turn off the power switch to prevent excessive discharge of the battery pack.

■ Battery Pack

To install the battery pack:

1. Confirm that the power is turned off at the GX-1 main unit:

that is, the switch is toggled down to .

2. Insert the battery pack into the power supply slot on the

right side of the GX-1.

Notes:

• What happens when the battery voltage drops to +11 V or less?

The message LOW BATTERY appears on the status bar of the provided software's window. When you see this message, promptly quit recording. If data is being recorded to the GX-1's memory at this time, transfer the data from memory to a removable medium or PC. When the voltage further drops to 10 V or less, the GX-1 automatically shuts down. However, since an idling current flows even during shutdown, turn off the power switch to prevent excessive discharge of the battery pack.

• Removing the battery pack

In the same way used to remove the AC adaptor, push the eject lever.

• With a fully charged battery pack, the GX-1 can record continuously for approximately 40 minutes (when using an AIT or an MO).

• To recharge a battery pack, follow the documentation for the battery charger.

• Nickel metal hydride batteries are susceptible to a "memory effect". Discharge the battery fully before recharging.

switch up to ( ).

Note:

When the power is turned on, the signal conditioners are calibrated automatically. When the calibration finishes, a buzzer sounds. (The buzzer consists of three pairs of beeps.) The time until the buzzer sounds depends on the types of signal conditioners that are mounted, and might take up to several minutes.

The buzzer will sound three pairs of beeps.

2. Turn on the power to the PC.

3. Start “GX Navi”.

Note:

While “GX Navi” is running, if the power to the GX-1 main unit is turned off and an attempt is then made to perform some operation with GX Navi, an error message is shown. If you then turn on the power to the GX-1 main unit again, the PC will be unable to recognize the GX-1. To enable the PC to recognize the GX-1, restart GX Navi.

● If startup time is unusually long

If the time between power-on and the buzzer sound is unusually long, or if the buzzer sound is abnormal, the signal conditioners may not be recognized. If the conditioners are not recognized, turn off the power and then on again.

■ Precautions for Use of AIT Drive

● Prevent condensation.

Use of this product in a warm room when the product itself is cool (for example, when you switch the product on in a warm room and start using it immediately), may cause condensation on the rotary head or the tape. When the product is cool but the room is warm, turn on the power to the product before inserting a tape cartridge and leave the power on for at least 30 minutes to warm up the product. Then, after confirming that there is no condensation, insert a tape cartridge. (In general, even if the room temperature is within the specified ambient conditions, a change in temperature of 15˚C per hour may cause condensation.)

● Operate in a horizontal position.

Place the unit in a horizontal position when you operate the AIT drive. Do not position the unit on its sides.

● Always eject the tape cartridge before turning off the power.

If a tape cartridge is left inserted for a long time after the power is turned off, the tape may adhere to the rotary head. If the power is turned on after this, the tape may jam on the rotary head and damage the head and tape.

● Periodically clean the head.

The head will gradually get dirty. Writing and reading cannot be performed correctly with a dirty head. As a guideline, use the specified cleaning tape (SONY SDX1-CL) to clean the head once every fifty hours of operation. To clean the head, turn on the power to the GX-1 and insert the cleaning tape into the drive. The drive will automatically perform cleaning and eject the tape after the cleaning is completed. For details on how to use a cleaning tape, see the documentation for the cleaning tape.

● Use specified tape cartridges only.

Use SONY SDX1-25C tape cartridges. Writing and reading cannot be guaranteed if any other tape is used.

● Be careful about the write-protection lug position to avoid deleting critical data.

To prevent important data from being deleted from a tape cartridge, make sure you slide the write-protection lug of the cartridge to the SAFE side.

● Follow the notes and precautions for the cartridge.

For details on handling of tape cartridges, read through the documentation that comes with the tape and follow the notes and precautions written.

2. Open the door to the MO drive.

3. Insert the MO disk with its label side faced up.

4. Close the door to the MO drive.

Wait until the activity display on the status toolbar shows “READY”.

■ Removing the MO Disk

To remove an MO disk:

1. Open the door of the MO drive.

2. Click the Eject button ( ) on the toolbar in the attached

software, or use the LCD controller to perform the Eject operation. The MO disk will be ejected.

3. Take the MO disk out of the GX-1.

4. Close the door on the MO drive.

Notes:

● You cannot remove an MO disk during recording or reading

of data. Pressing the EJECT button will have no effect.

● Quitting GX Navi automatically ejects the disk.

Eject MO Before Power-off

Remove the MO disk before turning off the power to the GX-1. If you turn off the power while the drive is writing, the data recorded on that MO disk might become unreadable. Also, moving the GX-1 with a disk in the drive may cause damage to the GX-1 or the disk.

About MO Disk

■ Use Specified MO Disk

Use 1.3 GB 3.5-inch MO disks manufactured by Fujitsu Limited. Writing and reading cannot be guaranteed if any other MO is used.

● The specified MO disks are not formatted. On inserting an

unused MO to the internal MO drive, a message will appear on the PC to prompt you to format it.

■ Data in MO Disk

To record data to an MO, first create a folder in the MO, and then record data into that folder. The data recorded on an MO can be read by a PC’s external MO drive as TAFFmat files and can be processed using commercially available analytical software.

■ Write-protect MO Disk

Write-protect an MO disk in which data is recorded before you insert it into a PC’s external MO drive. If not protected, and if you delete, move, or rename files or folders in it, the link between the data file and the header file will be lost, and as a result, the data become unreadable by PC or GX-1.

■ Cleaning the disk and lens

After a long period of use, the surfaces of the disk and the optical lens might collect dust: this can cause malfunctioning. To prevent this problem, clean the disk and the lens with the recommended cleaning kit (optional). Although the required cleaning depends on the usage environment, we recommend that you clean once every 3 months.

● To clean the disk, use the optional cleaning kit: TZ-381.

● To clean the lens, use the optional lens cleaner: 0240470.

● For details on how to clean, see the documentation that

accompanies the cleaning kit.
