Refer to the following illustrations for configuration and jumper locations for your DAT drive. There are two physically different types of AM-647 DAT drives: a 3.5” wide, half-height drive in a 5.25” mounting bracket, and a full 5.25” wide, half-height drive. Although their physical sizes and the locations of jumpers and switches are different, the same configuration rules apply to both. -

AM-64x DAT High Capacity Tape Drives Page 7 The AM-649-00 4 gigabyte DAT drive (HP model C1536A) has no provision to disable its term power! Therefore, this drive should only be installed in the main system chassis and connected to the same power supply as the rest of the internal SCSI peripheral devices. This drive should never be connected to a different/subsystem power supply, as erratic system operation may result! HP 4mm DAT Drive - Model C1536A (4 GB) -

AMOS software which returns the model number displays C1533A for either drive. When configuring the AM-649-01 drive, be sure to remove the TERM POWER jumper located next to the SCSI ID jumpers. -

AM-64x DAT High Capacity Tape Drives Page 11 10- and 21-slot rack mount VME computers have no external SCSI connector. To install an external terminator, you need a special adapter cable, DWB-10200-01. The connector on this cable is compatible with the external terminator and also allows you to easily attach a portable CD-ROM drive or other SCSI device. -

Page 12 AM-64x DAT High Capacity Tape Drives Figures 8a and 8b show two different types of external SCSI connectors: 1. Figure 8a shows an external narrow SCSI connector and bail locks for holding the terminator in place. This configuration is used on most of Alpha Micro's currently available product. The terminator is installed by plugging it onto the connector, then latching the bail locks into the notches on the sides of terminator. -

Page 26: Software Information For Dat Drives
• DAT tape drives are not supported in S-100 bus computers, or in AM-1000/1200 computers without a Roadrunner upgrade. • AM-647 drives must be used with AMOS 1.4 or 2.2, or later. • AM-648 and AM-649 drives must be used with AMOS 1.4C or 2.2C, or later. -
Page 27: Operating Software-Minimum File Versions
* Later model AM-649-01 drives (those labeled C1599A) require either AMOS 2.3A or AMOS 1.4C, PR 6/97. ** The AM-649 requires 647DVR.DVR from AMOS PR 3/96 or later. It will not work with earlier versions. 647DVR.DVR is backward-compatible; the latest versions support AM-647, AM-648, and AM-649 drives. PDI-00649-00, A01... -
Page 28: Copying The Generic Device Driver
Page 24 AM-64x DAT High Capacity Tape Drives If you use AMOS 2.2C we recommend you update MTUSAV, MTURES, MTUDIR, and TAPSER to the latest possible versions. Though the new versions are not absolutely necessary to use your DAT drive, they incorporate enhancements, such as improvements in the ability to span tapes. -

DEVTBL tells AMOS which devices to look for on the computer. Every time you add a new device to the system, like your DAT drive, you must add a DEVTBL statement defining it. -

This compressed data cannot be read by the AM-647 DAT drive. However, by using the TMODE command with standard DDS/DDS-1 tapes, you can force the AM-648 and AM-649 drives to write in standard DDS (non- compressed) mode.

Page 36 AM-64x DAT High Capacity Tape Drives DDS, DDS-1, DDS-2, and Media Recognition Over the past few years many improvements have been made to DAT tape drives, allowing newer drive models to use a higher compression scheme and store more data on a single tape. To accommodate the new high compression scheme, the Digital Data Storage (DDS) tape had to be improved. -
Page 41: Tape Capacities
With AM-647 DAT drives the 60 and 90 meter tapes yield capacities of approximately 1.3 GB and 2.0 GB respectively. If you attempt to use shorter tapes with the AM-647, the drive is not able to calculate the end of tape position. If the data you are saving exceeds the tape’s capacity, data will be lost! With AM-648 and AM-649-00/-01 DAT drives, 60 and 90 meter tapes written in DDS-DC compressed mode yield capacities of approximately 2.6 GB and 4.0 GB respectively.
