USER'S MANUAL
PCMCIA/JEIDA CARD READER/WRITER WITH SCSI INTERFACE
The MCDISK-G (Memory Card Disk) is a card reader/writer for PCMCIA/JEIDA compatible memory cards. MCDISK-G can
handle a wide variety of cards of any size: SRAM, ROM, OTP, E(E)PROM, FLASH, I/O and PC-ATA disks. To interface those
cards to the host equipment it has an SCSI interface. The SCSI interface is widely used for connecting mass storage devices
like hard disks to microcomputers.
A memory card can be thought of as an extremely fast disk storage device, because there are no latencies for moving
mechanical parts like read/write heads. In all other aspects however, a disk device and a memory card are much the same.
The MCDISK-G exists in two versions. The first one is equivalent to a 3.5" Floppy drive which can be easily incorporated into
OEM products. The second one is a desktop case with built-in power supply for easy connection to all computers with a SCSI
interface. However, although the reader/writer device is compact and economically priced, no concessions have been made
in its performance. It provides a fully professional yet highly economic solution to demands for data storage in harsh
environment. This makes the MCDISK-G ideal for use in many industrial and business applications with SCSI data input and/
or output.

1.4 CARD HANDLING
1.1 COMPATIBILITY
Follow the instructions as described in this section when
inserting and ejecting PCMCIA cards. Refer to Figure 5 to
locate indicated items.
MCDISK-G operates with various system platforms using
standard driver software. Some host systems do not fully
support MCDISK-G and require special driver software. MPL
AG provides a "Technical Note for MCDISK" that reflects the
actual status of software support for different host systems.
Additionally, this Technical Note lists PCMCIA card type
compatibility tests performed by MPL AG or MCDISK users.
1.4.1 INSERTING A CARD
When inserting a card into the card slot of the MCDISK-G,
care must be taken to ensure that the card is inserted
correctly. Follow these steps to insert the card:
1.2 OPERATION
1. Orientate the memory card so that the printed surface (e.g.
with manufacturer name/logo) is up and the 68-pin connector points towards the MCDISK-G card slot. Note that
some cards have an arrow indicating direction of insertion.
This chapter provides information about the use of the
PCMCIA cards and the LED indicators.
The illustration below identifies the items visible on the front
panel of the MCDISK-G.
2. Insert the card into the slot. It should slide easily into the
slot until approx. 15 mm remain exposed and the card
comes to a soft stop. At this point gentle pressure is
required to make the final connection between the
memory card and the card slot connector.
If the card comes to a sudden stop earlier than described
above, do not press any further! Key guides on the card
and in the card slot ensure that the card cannot be fully
inserted (does not reach the connector) when inserted in
the wrong way! Remove the card, check orientation and
try again.

3. When the card is fully inserted a small portion of the card
will remain exposed from the card slot opening. The red
LED on the front of the MCDISK-G will go off indicating that
the card is present. If the red LED remains lit then the card
has not been inserted correctly or cannot be operated by
the MCDISK-G (e.g. bad card type).
1.3 PCMCIA CARD TYPES
The MCDISK-G has been designed to accept three different
PCMCIA card types:
•
•
•
WARNING: Do NOT use excessive force to overcome any resistance when inserting the card. This
should not be necessary and will severely damage
both the card and the MCDISK-G.
Type I: Thickness 3.3 mm, no raised substrate area
Type II: Thickness 5.0 mm, 48 mm wide raised substrate
area
Type III: Thickness 10.5 mm, 51 mm wide raised
substrate area

1.4.2 EJECTING A CARD
1.5.2 ERROR SIGNALLING
To remove the PCMCIA card push the corresponding eject
button. The card is released from the connector inside and it
may now be pulled free.
In case of an error, the red and the yellow indicator will show
a diagnostic status:
•
Both indicators remain unlit: Ensure that the unit is connected correctly to a powered SCSI bus. Likewise the unit
cannot start-up when the SCSI bus is not or not correctly
terminated (TERMPWR OK?). If the SCSI bus is okay and
the indicators still remain unlit, there may be a hardware
problem and the unit requires service.
•
Both indicators flash only once and then remain unlit: The
internal RAM test has failed. The unit requires service.
•
The error LED flashes repeatedly: There is an SCSI
hardware problem.
•
The error LED double-flashes repeatedly: This indicates a
severe SCSI bus protocol error that prevents the MCDISK from continuing SCSI operation. The MC-DISK
needs to be reset to recover from this error. If the error is
permanent, check SCSI cabling, terminators and SCSI
ID's.
•
The error LED triple-flashes repeatedly: The ROM contents are not okay. The unit requires service.
•
The LEDs show some other pattern than those listed
above: There is a serious hardware problem, and the unit
needs to be returned to your local MCDISK-G supplier for
repair.
CAUTION: Do NOT attempt to pull the card free without first
pressing the card eject button!
Do NOT attempt to remove the card when the yellow LED is
lit (see also next section)!
WARNING: Avoid the situation where foreign objects, dust,
liquids etc. can enter the MCDISK-G through the card slot
opening. This can cause severe damage.
1.5 LED INDICATORS
The MCDISK-G is equipped with two LED indicators. Refer to
Figure 1.2 for the location of the indicators.
1.5.1 BASIC INDICATIONS
The yellow (right hand side) LED is the access indicator. It is
illuminated whenever an access to the memory card takes
place.
Don’t eject the PCMCIA card when the yellow LED is lit!
The red (left hand side) LED is the status indicator. It is
illuminated when the MCDISK-G is not operable due to one of
the following reasons:
•
•
There is no card inserted. If a card is inserted correctly, the
red LED will go off.
1.6 DRIVER SOFTWARE
If your MCDISK supplier has provided a driver software
package with your MCDISK-G, this must be loaded on the
host computer before commencing to work with the MCDISKG. Follow the instructions provided with the driver and/or the
procedures laid down for installing software on the host
computer provided in the host computer documentation.
If you have an Internet access you can visit our Web site at
There is a card inserted, but it cannot be accessed by the
MCDISK-G. Such errors can have various causes: the unit
is attempting to write to a write-protected or read-only
card, unknown I/O card, hardware error on a memory
card, etc.
During start-up (power up or SCSI bus reset), the MCDISK-G
performs some internal self tests. When everything is okay,
the red and the yellow indicator will flash twice simultaneously
to indicate proper start-up and proper SCSI connection.

2.5.2 TERMINATOR POWER (TERMPWR)
2.4.1 SCSI ID
Generally, the host computer is the only device on the SCSI
bus required to provide termination power for the bus. In
special cases like some notebooks it's neccessary to supply
the termination power via a peripheral device. If the MCDISKG is jumpered correctly, it can be used to supply the termination power to the SCSI bus.
Each device on the SCSI bus must have a unique SCSI ID
number. The numbers range from 0 .. 7 which allows for a
maximum of eight SCSI devices on the bus. Before setting the
SCSI ID for MCDISK-G, an ID must be chosen that is not yet
used by other SCSI devices. Usually, most host computer
systems already use SCSI ID 0 (internal SCSI hard disk drive)
and SCSI ID 7 (host computer itself). Check the documentation of the host computer and the attached peripheral SCSI
devices to verify the available SCSI ID numbers.
The MCDISK-G contains internal components to provide
Active Termination of the SCSI bus. Compared to Passive
Termination, Active Termination is far less sensitive to
TERMPWR voltage variations, which, amongst other things,
increases data security.
Figure 2.5.2 shows the terminator circuit as used on the
MCDISK-G:
WARNING: Ensure that each SCSI device has a
unique SCSI ID number. If not, serious corruption of
data and/or failure of the host computer may result!

5.0V
2.4.2 OPTIONAL FEATURES
Two optional features can be configured at J2: SCSI parity
and CIS mode (refer to figure 2.3).
The SCSI parity configuration of the MCDISK-G should match
that of the host computer. Check the host computer documentation to verify its setting. On delivery, the MCDISK-G’s parity
is disabled which should be OK for most system integrations.
The parity can be enabled by installing a jumper across the
referenced pins.
PCMCIA/JEIDA cards supporting CIS (Card Information
Structure) can be automatically identified by the MCDISK-G.
On delivery, CIS mode 00 (both jumpers not installed) is set
and should not need to be changed. Very special applications
might require a different CIS mode. In such a case, refer to the
corresponding sections in the ‘MCDISK Technical Reference
Manual’ first.

2.6 MOUNTING
This chapter provides the procedure for mounting and fixing
the read/write unit.
WARNING: Before commencing, verify that the
host system is switched off and disconnected from
the mains power. Review and observe the safety
precautions described at the beginning of this
manual to avoid personal injury or damage to equipment.
2.6.1 GENERAL HINTS
You can mount the MCDISK-G in any position. The read/write
unit's placement must permit sufficient airflow to ensure that
it operates within the environmental limits listed in Chapter 1
under 'Specifications'.
Depending upon your specific system, you may wish to attach
the power and SCSI cable before mounting the unit in the
system. In such a case, read Chapter 2.8 first.
2.6.2 HARDWARE REQUIRED
The MCDISK-G-1 can be installed in a 3.5" bay or any custom
manufactured support with only four M3 screws. Typically,
screw length is 6 mm, but can vary depending upon enclosure
or support thickness.
CAUTION: Ensure that screws used to mount the
read/write unit do not extend beyond the frame into
the PCB cavity, otherwise damage to the PCB may
result.
2.6.3 MOUNTING THE UNIT
The MCDISK-G is equivalent (in size and mounting) to a
standard 3.5" slim-line floppy disk drive. In most cases, this
simplifies the installation of the read/write unit. To mount the
unit:
•
Position the unit in the 3.5" bay (and the enclosure cutout)
and gently move it until the four screw holes are aligned.
•
Insert and secure the screws at these locations.

3.3.1 SET-UP OVERVIEW
Set-up of MCDISK-G-5 is a step by step procedure:
3.3.3 SCSI ID
1. Remove the drive from its packing.
2. Set the unit’s SCSI ID (see chapter 3.3.3).
3. Terminate the SCSI bus if required (see chapter 3.4).
4. Connect the unit to the host computer
5. Connect the AC power and switch the unit on.
In the desktop case only the SCSI ID is available via a
pushwheel on the rear panel. Through simple pressing with a
pencil or something similar on the + or - button the SCSI ID can
be changed. All other changes or features must be done the
same way as in the open frame case. Please refer to chapters
2.3 and 2.4 for detailed information.
