1. SAFETY INFORMATION

This service manual is intended for qualified service technicians; it is not meant for the casual
do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
trained to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.

WARNING
This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause
cancer, birth defects or other reproductive harm.

Health & Safety Code Section 25249.6 – Proposition 65

NOTICE
(FOR CANADIAN MODEL ONLY)
Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts
must be of identical designation.

REMARQUE
(POUR MODÈLE CANADIEN SEULEMENT)
Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les
pièces de remplacement doivent avoir la même désignation.

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be performed for the

continued protection of the customer and service
technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground
(water pipe, conduit, etc.) by connecting a leakage
current tester such as Simpson Model 229-2 or

equivalent between the earth ground and all exposed
metal parts of the appliance (input/output terminals,
screwheads, metal overlays, control shaft, etc.). Plug
the AC line cord of the appliance directly into a 120V
AC 60 Hz outlet and turn the AC power switch on. Any
current measured must not exceed 3.5 mA.

Reading should
not be above

3.5 mA

Earth ground

Device
under
test

Also test with plug
reversed
(Using AC adapter
plug as required)

Leakage

current

tester

Test all exposed
metal surfaces

AC Leakage Test

ANY MEASUREMENTS NOT WITHIN THE LIMITS
OUTLINED ABOVE ARE INDICATIVE OF A PO­TENTIAL SHOCK HAZARD AND MUST BE COR­RECTED BEFORE RETURNING THE APPLIANCE
TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appli­ance have special safety related characteristics. These
are often not evident from visual inspection nor the
protection afforded by them necessarily can be ob­tained by using replacement components rated for
voltage, wattage , etc. Replacement parts which have
these special safety characteristics are identified in
this Service Manual.
Electrical components having such features are
identified by marking with a
on the parts list in this Service Manual.
The use of a substitute replacement component which
does not have the same safety characteristics as the
PIONEER recommended replacement one, shown in
the parts list in this Service Manual, may create shock,
fire, or other hazards.
Product Safety is continuously under review and
new instructions are issued from time to time. For
the latest information, always consult the current
PIONEER Service Manual. A subscription to, or ad­ditional copies of, PIONEER Service Manual may be
obtained at a nominal charge from PIONEER.

SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

Additional Laser Caution

(Holder Top)

1. Laser Interlock Mechanism
The ON/OFF (ON: low level, OFF: high
level) status of the LPS1 (S601) switch for
detecting the loading state is detected by
the system microprocessor, and the
design prevents laser diode oscillation
when LPS1 (S601) is not ON (low level)
(clamped srate).
Thus, interlock will no longer function if
switch LPS1 (S601) is deliberately
shorted.

In the test mode∗ the interlock mechanism

will not function.
Laser diode oscillation will continue, if pin 2
of AN8849SB (IC201) on the MAIN
BOARD assy is connected to GND, or else
the terminals of Q201 are shorted to each
other (fault condition).

2. When the cover is opened with the servo
mechanism block removed to be turned
over, close viewing of the objective lens
with the naked eye will cause exposure to
a Class 1 laser beam.

7.2.1 DIAGNOSIS METHOD FOR MULTI MECHA ASSY AND HDD

This unit is equipped with an external SCSI terminal. Accordingly, when the SCSI cable is
disconnected from the AXIS NETWORK BOARD Assy, the external SCSI terminal is connected
to the SCSI controller of the PC A/T, and the terminator setting is changed, the built-in HDD and
the MULTI MECHA Assy can be operated from the PC A/T as SCSI devices, and analysis is
possible.

7.2.3 TROUBLESHOOTING

This section provides useful information to help you
resolve any difficulty you might have with your DRM-

6NX, namely:

÷ The front panel indicators
÷ Errors when accessing the DRM-6NX
÷ Problems running CD-ROM software
÷ Difficulties locating the DRM-6NX in NetWare
÷ Problems locating the domain controller in SMB
÷ Problems when accessing disc changers
÷ Restoring the factory default settings

The Front Panel Indicators

The front panel indicators show the status of the DRM­6NX. The indicators have the following functions:
÷ Status - Flashes during startup. When the DRM-6NX

is ready for use, the light goes out. The LED remains
off, unless an error condition occurs.

÷ HDD - Flashes to indicate hard disk activity and SCSI

activity.

Caution!

Never turn off the power when the hard disk
drive is active (while HDD indicator is flashing).

÷ Network - Flashes to indicate the presence of network

traffic.

÷ CHANGER - Light when data is read from the internal

changer and when the SCSI bus is accessed.

÷ Power - Indicates that power is connected to the

DRM-6NX. This LED should remain lit and is only
used to indicate power is present in the DRM-6NX
unit.

Error Conditions

This table shows the front panel indicators under various
error conditions:

Event

or SCSI bus not connected**
Faulty network connection OFF OFF
Illegal serial no. Flash Flash Flash
Flash load failed Flash OFF OFF
Token-Ring loopback failure

* The Network LED will flash when there is network traffic.
** Check the logfile.txt file in the System folder for more information.
*** The HDD LED and Network LED will flash alternately in this condition.
**** Disable the function by setting the Disconnect/Reselect parameter to

off.

Status LED HDD LED Network LED

OFF Flash Flash*

Flash Flash OFF

Flash Flash OFF

Flash Flash*** Flash***

Flash

Status Indicator On

If the Status indicator remains lit after startup, this may
indicate an error. Most likely there is a problem with the
SCSI bus or with any of the connected disc drives. Make
sure all connected drives have unique SCSI addresses
and that only the last drive in the SCSI chain is terminated.

÷ If some drive error occurs during caching/reading,

caching/reading is canceled and the drive and discs
become disable.

Errors when Accessing the Network
Cache Changer or Inserted Discs

If you get error messages when trying to access the
DRM-6NX or an inserted disc:

÷ Using TCP/IP, make sure that you have assigned a

unique Internet address to the DRM-6NX.

÷ Check the SCSI chain and ensure that all external disc

drives are switched on and that only the last unit is
terminated.

÷ Using Microsoft Windows Network, verify that you

have enabled the SMB protocol.

÷ Consult the error table in section “Error Conditions”

to see if the front panel indicators can help you
identify the problem.

Problems Running CD-ROM Software

If you have inserted a CD-ROM successfully, but the
software on it refuses to run or produces error messages,
the software may expect the CD-ROM data to be at root
level. In NetWare as well as in the Microsoft and IBM
network operating system environments, you then
need to assign a drive letter to that particular CD-ROM.
In NetWare, the Show All Volumes parameter must be

enabled. See also “Accessing the Network Cache
Changer Resources”.

Some CD-ROMs, e.g the single user version of
“Computer Select”, requires the MSCDEX (Microsoft)
driver. The volume is usually released in a network
version as well. An MSCDEX emulation, called
PIONEERCDEX, is available on the Axis web site. The
PIONEERCDEX makes a CD-ROM on the DRM-6NX
look as if it was locally connected to the PC.
PIONEERCDEX supports Windows for Workgroups.
An MSCDEX emulation for Windows 95 is also available.
If the CD-ROM is a single user version, you must restrict
the number of simultaneous users to one.
Some applications look for information on the CD-ROM
using its default name - if you have set an alias name it
may not recognize the disc and fail to run.

Difficulties Locating the Network Cache
Changer in NetWare

Frame Types - Ethernet

There are basically two different frame types on Ethernet
networks, Ethernet II or IEEE 802.3. The IEEE 802.3
frame can be encapsulated in an IEEE 802.2 LLC frame
or a SNAP frame. All four frame types are enabled by
default with the value
6NX automatically adapts to the frame type used on the
network. This will meet most requirements. Frame
types that are not in use in your network will not be used
by the DRM-6NX.

However, depending on your network, you may want
the DRM-6NX not to operate on some frame types. If
your network has multiple sections with different frame
types on some of the sections, then the DRM-6NX
might log on to the wrong network section and adapt to
a frame type incompatible with the intended network
section. For this reason, you have the option to disable
those frame types by changing the parameter from
to

off

.

, which means that your DRM-

auto

Alternatively, it is possible to use the eight digit network
number appropriate to your segment of the network, in
the form xx-xx-xx-xx (e.g. 00-3F-B5-01). In all normal
cases this will not be necessary since autodetection will
handle most cases. However, this has to be done by
directly editing the

config.txt

file using a text editor.
Although you cannot enter the network number from a
Web browser, you can display the frame type and
change the value to

auto

or

off

, if required.

Problems Locating the Domain Controller
in Windows (SMB)

If there is a problem locating the primary domain
controller when using user-level security mode in
Windows (SMB), all users will be denied access to the
DRM-6NX.

Web Browser

You can verify the configuration settings from the DRM­6NX web interface. Within the Administration pages,
click Network Settings, Detailed View, and open the

Windows (SMB) tab to do that.

Local Administrator Account

In Windows NT, you can correct the problem by logging
on to the DRM-6NX as local administrator. Note that the
local administrator is not the same as an Administrator
with an account on the domain.

In the Map Network Drive dialog, specify the following:

Path: The DRM-6NX name
Connect as: Server name\Administrator
Password: The password set in the

Example:

The host name of the DRM-6NX is cdserv.

DRM-6NX

Problems When Accessing Disc Changers

Disc changer flutter can occur if a user requests access
to a CD-ROM when another user is already reading data
from another CD-ROM. The changer may then attempt
to service both requests by repeatedly changing
between the two CD-ROMs and transferring a small
amount of data each time. Because of the relatively long
time needed to change CD-ROMs, the data transfer
rate to both users will become unacceptably low.

The JukeBox Lock Time parameter in the DRM-6NX
configuration file specifies how long a user has exclusive
access to a CD-ROM during a data read operation. This
is to prevent disc change flutter in order to optimize
access speed when many users are accessing different
discs in the same changer.
The JukeBox Lock Time parameter will ensure that
when there are simultaneous requests for access to
different discs, a sizable block of data is transferred to
each user before the access is changed.

÷ If the JukeBox Lock Time parameter is set too low,

the data transfer rate will be unacceptably low.

÷ If the JukeBox Lock Time parameter is set too high,

the disc drive will time-out on a second user’s request
before the first user’s access is completed. This will
result in users receiving a ‘CD-ROM not available’
notice.

The default setting is 0 seconds which disables this
function.

NOTE:

7 If some drive error occurs during caching/reading,Caching/Reading is

canceled and the drive and discs become disable.

Only restarting this product cam clear this condition.

Flash Memory

The software that runs on your DRM-6NX is stored
in Flash Memory. This is a memory chip that, like
ordinary ROM memory, keeps its contents even
when the power is turned off. What makes it
unique is the possibility to erase its contents and
write new data to it. This means that when software
updates are available for your DRM-6NX, you can
make use of them without having to replace any
parts. The new software is simply loaded into the
DRM-6NX over the network.

Your Dealer

Contact your dealer to check if there has been any new
issues of the software. You should have your present
version numbers ready to compare against the latest
software issues from PIONEER.

Upgrading the Networ Cache Canger

The DRM-6NX software can easily be upgraded over
the network using FTP on a TCP/IP network.

To upgrade over the network you will need the following:

÷ The file with the new DRM-6NX software. The name

of this file is of the form
for the software release 5.00 for the Ethernet version
of the DRM-6NX.

÷ A computer on the network with TCP/IP and FTP.
÷ The DRM-6NX must also be installed on the network

with TCP/IP as described in “Assigning an Internet
Address”.

Follow these steps to upgrade the DRM-6NX:

1. Log in to the DRM-6NX with the command:
ftp <host name>

where

Internet address of your DRM-6NX.

2. You will be prompted for user id and password. Use
the user id

7 If you intend to download an earlier version or a beta version, you need

to type FLASH in capitals, i.e. put <software name> FLASH, to force
a flash memory load.

is the name of the new software, e.g.

.

5. Wait for the flash memory load to finish. This normally
takes 1 to 4 minutes. The unit will then automatically
restart with the new DRM-6NX software.

6. Log out using the command quit, bye or exit depending
on your FTP version.

7. After upgrading new firmware, you have to restore
the factory default setting.

Caution!

Be careful not to interrupt the file transfer. If the
transfer is interrupted the DRM-6NX may have to
be re-initialized by your dealer.

DRM-6NX

Upgrading the Internal Drives

The internal disc drives can be upgraded via the DRM­6NX web interface.

Follow these steps to upgrade an internal drive:

1. Make sure you have the new software available on
the network.

2. Start the Web browser.

3. In the location/address field, enter the name or
Internet address of your DRM-6NX.

4. Click Administration.

5. Click This DRM-6NX.

6. Click on the icon that represents the device you want
to upgrade.

7. If the firmware upgrade capability is detected for the
selected drive, you can click Upgrade Firmware...

8. Locate the new software file and click OK.

Upgrading using the Parallel Port

You will need:

÷ A PC with at least a 286, 640 kb memory, MS-DOS

3.3 or greater.

÷ DRM-6NX flash loading kit consisting of:

÷ Flash loading cable
÷ Loading software: FSTPRN.EXE

÷ The file containg the new software version

How to upgrade

1. Switch off the power.

2. Remove the bonnet.

3. Disconnect the LAN cable and the SCSI connector
from the AXIS NETWORK BOARD Assy.

4. Connect the parallel cable to the PC LPT1 port and to
the 26-pin array on the AXIS NETWORK BOARD
Assy. Make sure the parallel cable connector is
mounted with the arrow, close to pin 1, facing the
ETRAX chip located in the middle of the PCB.

5. Switch on the power to the DRM-6NX.

6. Copy the flash load software (FSTPRN.EXE) and the
new software file to a common directory.

7. Start the loading sequence with the DOS command
fstprn <binary file> .

It is also possible to load the print server with the
standard DOS copy command:
copy /b <binary file> LPTx (x = LPT port no.)

NOTE:

Do not forget the /b (for binary) switch in the copy
command.

How to monitor the loading procedure

When the loading is started, the network LED will start
flashing with rate of 2 Hz (loading time between 30 sec
and 4 min).

The loader will consider itself completed and the led will
flash with a rate of 0.5 Hz.

In case of error, the flashing rate will be 1 Hz (with the
on period much longer than the off period).
There will also be a message on the PC screen telling
you if the loading was successful or not.

Final steps

If you have made a software update including parameter
changes (e.g. from 1.x to 2.x) a reset to factory defaults
is required.

54

For restoring to the factory default settings, refer to
"Restoring Factory Default Settings" in "Troubleshooting".

Assemble the DRM-6NX and attach all cables.

Disconnect the SCSI connector
and LAN cable.
