Identifying your floppy Drive

OEM production models are not listed in this knowledge base; you need to contact the manufacturer of the piece of equipment where your floppy drive was originally installed in order to receive information for repair, replacement, and availability.

1. All TEAC 3.5 floppy disk drives have the prefix TEAC FD235HS-1111 scsi floppy drive, which denotes the size of the disk: 3.5 drive.
   　

2. The next two characters in the model nomenclature denote the density, and type of interface of the device:
   
   HS: Dual Density: 720K and 1.44MB; the letter S denotes the SCSI interface.
   　

3. The suffix denotes the series information:
   
   FD235HS-1111
   FD235HS-1011
   FD235HS-911
   FD235HS-711
   　
4. The color of the bezel for the TEAC FD235HS-1111 series remains the same. Please refer to thexu@ruanqu.net for details.

1. If your drive is not yet installed, you can identify it by its model label, which is located in the bottom side, towards the front side of the drive. Refer to figure A for details.

Figure A

1. The nameplate in the back of the drive does not indicate the model nor serial number in your drive. Always, refer to the label in the bottom side of the drive.
   　
2. If your drive is already installed in your system, then you may find the model number in your invoice. Please keep your invoice in a safe place since this is your proof of purchase and you will be required to send us a copy for repair.

Driver information

Although the TEAC FD235HS-1111 floppy drives have a standard SCSI interface, there are no drivers available from TEAC. You need to create your own drivers.


The process of development and implementation of software drivers is unique to each PC and NON-PC applications; and for that, the SCSI Command Set of Instructions is available at request to our Technical Support Department at DSPDTSG@TEAC.COM.
You are required to read, and sign our Non-Disclousure Agreement (NDA) and return it to us via fax: http://www.ruanqu.net . You should receive the manual upon approval.

installation

Introduction

The quality of the TEAC FD235HS-1111 drives provide a trouble-free operation for your computer system if properly installed. The following information will guide you thoroughly through an easy step-by-step method for a proper installation of your floppy disk drive.



Your TEAC FD235HS-1111 drive must be handled with care. Avoid applying undue force or abnormal strain to the spindle motor, stepping motor or printed circuit board assembly (PCBA).

It is best to hold the drive by the sides. Never loosen the fixing screws of the PCBA.


Preparing your system

CAUTION: TURN OFF YOUR COMPUTER AND UNPLUG IT FROM THE AC POWER SOURCE BEFORE INSTALLING THE TEAC FD235HS-1111. FAILURE TO DO SO MAY RESULT IN ELECTRIC SHOCK.



1.


Unplug your computer.

2.


Detach all peripheral devices from your computer, such as printer, keyboard, mouse, etc.

3.


Remove cover from your computer. Refer to your computer manual for this procedure.

4.


The floppy interface cable is the flat ribbon type, and the power connector consists of the 4 separate wires attached to a single connector.


Configuring the TEAC FD235HS-1111 Floppy Disk Drive

1.


If this is the only device connected to your SCSI card, then make sure termination is enabled; otherwise, you need to verify that the drive's SCSI ID # does not conflict with any of the other devices connected to the chain; if the drive is not connected at the end of the chain, then you need to disable termination as well.

2.


Use a standard 50-pin SCSI interface cable to complete the installation.

3.


Connect the TEAC FD235HS-1111 floppy disk drive to the 50-pin SCSI cable.
Installing the TEAC FD235HS-1111 Floppy Disk Drive

1.


Slide the drive into the available standard 1 high bay.

2.


Locate the SCSI cable, and connect the red or blue stripe into pin # 1 in the drive, which is located towards the power connector in the drive.

3.


Connect the power connector to the drive.

4.


Place the screws through each set of holes in the drive.

5.


Be sure to have a copy of the SCSI Command Set manual so you can create your own drivers to make the interface possible between the TEAC FD235HS-1111 and your SCSI application. Refer to the Driver Information section for details.
