Safety Summary
xProfile PLS20 Data Tape Drive
Welcome
Congratulations on selecting the PLS20 Profile Data Tape Drive. The PLS20
lets you quickly (up to 3 megabytes per second) and economically store your
audio and video material from your Profile Professional Disk Recorder on
durable data tape cartridges for archive purposes, or to move material to remote
locations without video networking.
The PLS20 Profile Data Tape Drive tape drive is a tabletop model housed in its
own enclosure (shown in Figure 9).
Welcome
.

Profile PLS20 Data Tape Drive1
Installing the PLS20
The following sections explain how to install a Profile Data Tape Drive and
connect it to a PDR100 or PDR200 Professional Disk Recorder.
Location of components
When installing the PLS20, refer to Figure 10 for the location of components
on the rear panel.
0183-9
Figure 10. Component locations
Set the SCSI ID
To set the SCSI ID for the tape drive, use a pen or other fine-tipped instrument
to press the SCSI ID switch. Set the SCSI ID to 1 or 2., and ensure that no other
SCSI device on the bus is using the same ID.
NOTE: Changes in the SCSI ID setting take effect after a normal
power-on or SCSI bus reset.
2Profile PLS20 Data Tape Drive
Install the Orientation Pads
The tabletop model includes adhesive pads that you must apply to either the
base or the right side, depending on how you plan to position the tape drive.
These pads protect the tape drive’s surface and allow air to flow through the
vents when the tape drive is positioned on its side.
To install the pads:
1. Remove the backing from four pads. (Five pads are shipped with the tape
drive.)
2. Affix the pads to each corner, approximately -inch (1.3 cm) from the sides.
For a horizontal orientation, place the pads on the bottom. For a vertical
orientation, place the pads on the right side (the side with the external vents).
Install the Orientation Pads
0183-8
Figure 11. Installing the orientation pads
>>> If you want to position the tape drive on its side, you must place the pads on
the right side. Otherwise, the air flow vents will be blocked and the enclosed
tape drive will overheat.
Profile PLS20 Data Tape Drive3
Connect the Drive to the SCSI Bus
The PLS20 receives both data and commands through a single SCSI connector.
Figure 12 shows examples of how to connect your tape drive to a Profile
system.
CAUTION: To avoid damaging the tape drive and the Profile Professional
!
Disk Recorder, make sure that both devices are powered off when you
connect the cables on the back.
1. Connect the tape drive to one of the SCSI ports on the Profile rear panel with
the provided cable.
a. On a PDR100, connect to the SCSI A or SCSI B connector, or to another
device in the chain connected to that bus.
b. On a PDR200, connect to the SCSI B or SCSI D connector, or to another
device in the chain connected to that bus.
2. If the tape drive is the last device on the SCSI bus, install a terminator on the
other connector. If it is not the last device, connect another SCSI cable. Do
not install more than four Profile Data Tape Drives to a single Profile system.
NOTE: You may not connect a PLS200 Profile Library System and
a PLS20 Profile Data Tape Drive to the same Profile system.
However, you may connect up to four Profile Data Tape Drives to the
same Profile system, provided you do not exceed two PLS20s per
SCSI bus.
See Appendix A for cable and terminator requirements.

Connect Power
To connect power to the tape drive:
1. Connect the power cord to the back.
2. Press the power switch to the on (l) position.
Be sure to power on the PLS20 before starting the Profile system to
ensure that the Profile Data Tape Drive is recognized as a SCSI
device.
The tape drive performs its power-on self-test in about 30 seconds. When the
tape drive is ready to accept a cartridge, the LEDs turn off.
➤ Important: Do not insert a cartridge into the tape drive during the
power-on self-test. The tape drive will eject the cartridge.

The status LEDs have the following, general meanings:
• Top LED (amber). When this LED is flashing, an error has occurred. When
this LED is on solid, the tape drive needs to be cleaned (see page 14).
• Middle LED (green). When this LED is on, tape is loaded and the tape drive
is ready to begin operations.
• Bottom LED (green). When this LED is flashing, tape motion is occurring.

Profile PLS20 Data Tape Drive11
Selecting Appropriate Data Cartridges
For writing data, use only Profile 170m advanced metal evaporated (AME) data
cartridges, as shown in Figure 14. You must use Profile Media Manager to
format these cartridges before using them in a PLS20 connected to a Profile
Professional Disk Recorder. See the Profile Family User Manual for
information on running Profile Media Manager.
Data cartridges are completely interchangeable between a PLS20 Profile Data
Tape Drive and a PLS200 Profile Library System.
0183-7
Figure 14. A PLS20 170m tape cartridge
Loading Data Cartridges
To load a cartridge:
1. Make sure the tape drive is ready to accept a cartridge (all LEDs are off). Do
not insert a cartridge if the tape drive is still performing its power-on selftest.
2. Set the write-protect switch for the desired operation as shown in Figure 15.
Figure 15. Setting the Write Protection switch

3. Insert the cartridge as shown in the Figure 16.
Figure 16. Inserting the tape cartridge
The tape drive loads the tape in approximately 20 seconds. When the middle
LED is on, the tape drive is ready for read and write operations.
Unloading Data Cartridges
Unloading Data Cartridges
0183-5
In normal operation, you should use the appropriate command in Media
Manager (or any other Profile application that supports Profile Library
Systems) to eject or export a data tape from the PLS20. See the Profile FamilyUser Manual for information on running Profile Media Manager.
In some cases, such as when the PLS20 is not connected to a Profile system,
you may have to manually unload a data tape from the PLS20.
To unload a cartridge, press the unload button. Do not press and hold the
unload button for more than 10 seconds; this can cause a reset under
certain conditions. If the tape drive is free of errors, it performs the following
actions in about one minute:
• Completes any command in process
• Writes any buffered information to tape
• Rewinds the tape to the beginning
• Unloads the tape and ejects the cartridge
Profile PLS20 Data Tape Drive13
NOTE: If an error occurs before or during the unload procedure, the
tape drive suspends the unload sequence. To clear the error, press the
unload button again. The tape drive reattempts the unload sequence,
but does not write data in the buffer.
Resetting the Tape Drive
To reset the tape drive, press and hold the unload button for at least 10 seconds,
or power the drive off and back on again.
If you reset the tape drive while a cartridge is loaded, it rewinds the
tape to the beginning after the reset is complete. The reset may take
as long as two minutes if the tape is positioned near the end.
Cleaning the Tape Drive
When the tape drive requires cleaning, the top (amber) LED turns on. You
should clean the tape drive as soon as possible after this LED turns on. The tape
drive’s cleaning requirements depend on the number of tape motion hours
To clean the tape drive, insert an Profile 8mm Cleaning Cartridge (or a cleaning
cartridge approved by Tektronix for use with the PLS20). When finished, the
tape drive turns off the top LED and ejects the cleaning cartridge.
Cleaning cartridges generally have a useful life of about 12 cycles. Be sure to
change your cleaning cartridges often to ensure the best results.
14Profile PLS20 Data Tape Drive
Packing the Tape Drive
If you are shipping the tape drive to another location or returning it for repair,
pack the tape drive in its original shipping container and packing materials.
CAUTON: To avoid damaging the tape drive and voiding your warranty, use
!
the original shipping materials (or replacement materials from your dealer).
➤ Important: If you are returning the tape drive for service, remove and
keep all cartridges, cables, and terminators.
If you are returning the tape drive to Tektronix, contact Tektronix Product
