Introduction

The NEC CD Sentry utility will provide information about your SCSI interface and your NEC CD-ROM reader.  CD Sentry can also be used to modify your reader's internal configuration.  See the section Operation for more information on controlling your CD-ROM reader.


Requirements

You will need the following system components in order for CD Sentry to operate:

⇒	Windows 3.x

⇒	NEC 6Xe or 6Xi CD-ROM reader

⇒	Adaptec, Trantor or Future Domain SCSI Interface

⇒	Updated SCSI drivers:

•	Adaptec:	EZSCSI 3.1 Drivers (included)

•	Trantor:	ASPI Manager version 2.0 (included)

•	Future Domain:	Windows Virtual Device Driver (included)


Operation - Overview
Overview

Your screen should display a button for each SCSI ID in addition to a host adapter box plus folders which contain information about each CD-ROM and disc.  Below are instructions on how to use each function and what each function does.


SCSI Interface

Listed in the SCSI Interface box is a list of the installed SCSI Host Adapters that are currently in your system.  To select another adapter other than the one currently listed, click on the "SCSI Interface" box and choose the interface.  Upon selection of the interface, the SCSI ID buttons will reflect the currently installed adapter.

If you do not see any adapters listed, refer to the Troubleshooting section.


SCSI ID's

The SCSI ID Buttons display the currently installed SCSI Host Adapters in your system.

To view information about the disc in a particular device, or to adjust the settings of your NEC CD-ROM reader, click on the appropriate SCSI device.

Once you click on the device that want, CD Sentry will gather information about the CD that is loaded in the reader.  This may take up to 15 seconds.

Once CD Sentry has gathered all of the information, the folder tabs located on the right show the information.

If you receive a "Drive not Ready" error, insert a CD into the reader and try again.


Folder Tabs

Disc Information

Track Information

Functions


Disc Information

Device ID

This is the name of the device that this attached to the SCSI Host Interface.  It is the same as the inquiry string returned from the device.

Disc Capacity

The amount of data that is on the CD currently loaded in the reader.

First Track

The first track number on the CD.

Last Track

The last track number on the CD.

Disc Type

The type of disc that is currently in the reader.  The possible disc type are listed below:

Audio

Standard Data

Multisession Data

Multisession Photo

XA

CD-I

Mixed Mode


Track Information

Catalog Number

An identifier that describes the disc that is currently in the reader.  Not all CD's have a Catalog Number.

Start Time

The starting time for each track on the CD.  The track is given in the following format:

Minutes:Seconds:Frames

End Time

The ending time for each track on the CD.  The track is given in the following format:

Minutes:Seconds:Frames

Track Type

The track type will be either Data or Audio.

Digital Copy

Digital Copy states whether the track is permitted to be copied or prohibited.

You will need to check with the manufacturer of the CD to determine if you need special permission to copy a track.


Functions

Media Removal

Set this option to prevent the CD from being ejected.

Transfer Rate

If you are having trouble reading a specific disc you may want to try setting the transfer rate to Minimum.  This sets the transfer rate to 1X (150 KB/S) mode.  To bring the reader back to normal operation, set this to Maximum.

Spin Down Time

Sets the delay before the reader stops the disc spinning.  The range is from 1 second to no spin down.

Buffer Ratio

The percentage of the internal 256 KB cache that data is stored into before the data is transferred to the computer.  The smaller the percentage, the faster the data is returned.  The larger the number, the greater the potential for reducing your access time.

Send Diagnostic

This checks the internal operation of the CD-ROM reader.  If you suspect that there is a problem with the reader, select "Send Diagnostic".  This test can take up to 10 seconds.  If the Send Diagnostic fails, call Technical Support at 800-388-8888 to verify if your reader has a problem and needs to be serviced.

Line Out Volume

You can adjust the Line-Out volume located at the back of the reader or the headphone jack for both the left and right channel.  This can be performed while the reader is currently playing an audio disc.

Set Options

You must select "Set Options" before any of the above settings are recorded.


Adaptec

I can't get CD Sentry to recognize the interface.

Make sure that you are using the latest drivers from Adaptec.  You will need to have EZ-SCSI 3.l drivers loaded for CD Sentry to work properly.  Your config.sys, autoexec.bat and system.ini files should look as follows:

Config.sys:

device=c:\scsi\aspi2dos.sys

device=c:\scsi\aspicd.sys /d:ASPICD0

Autoexec.bat

c:\scsi\mscdex /d:APSICD0 /m:10

System.ini

[386 Enh]

device=c:\scsi\vaspid.386

I get an error stating that "VASPID.386" needs to be loaded.

You need to add the VASPID.386 file to your system.ini file located in your Windows directory.  The line to add is as follows:

System.ini

[386 Enh]

device=c:\scsi\vaspid.386


Future Domain

I can't get CD Sentry to recognize the interface.

Make sure that you are using the latest drivers from Future Domain.  You will need to have PowerSCSI 4.0 or later loaded for CD Sentry to work properly.  Your config.sys, autoexec.bat and system.ini files should look as follows:

Config.sys:

device=c:\scsi\fdcd.sys /d:MSCD001

or

device=c:\scsi\neccdr.sys /d:NECCD

Autoexec.bat

c:\scsi\mscdex /d:NECCD /m:10

System.ini

[386 Enh]

device=c:\scsi\v18fcamd.386


Other

Other interfaces are not supported at this time.  This is due to ASPI for Windows DLL's not being available for the other interfaces.  At a later time, if more DLL's become available, we will offer an update on our BBS.  The BBS number is 508-635-4706.


Windows 95

We will have a Windows 95 version of CD Sentry sometime after Windows 95 is released.  This version will be made available on our BBS.  The BBS number is 508-635-4706.

We expect to have support for all ASPI interfaces at this time.
