PCD-47B User's Manual
PCD-47 Firmware v 3.1 May 10, 2001
PCD-47 Firmware v 3.2
Using the PCD-47B on a PS/2
First, give up the idea of using this on an IBM made SCSI
adapter. You'll get nothing but frustration when the System Programs tries
to handle the empty slots. You can configure it, but imagine running setup
every time you insert a new device...
Use a common FD MCS-700/Patriot , Buslogic BT-646, or Adaptec
AHA-1640. These will not show up under Set and View SCSI Devices, so you
can insert and eject devices without having to reboot.
Stuff I have Used So Far:
256MB Compact Flash, 256MB Secure Digital in PCMCIA adapter,
64MB Smart Media, 105MB PCMCIA HD. I suspect that hot insert has difficulty
with the SM card, I had to reboot to see it.

Selecting SCSI IDs
The PCD-47 requires three SCSI IDs. So you can choose IDs 0 through
4 and have an ID for each device. For example, ID0 (all ID jumpers open)
results in ID0 for PCMCIA, ID1 for Smart Media, and ID2 for Compact Flash.

The manual and the sticker agree on the SCSI ID to Slot ID. Look at
the drive with the SCSI ID block on the upper left side and the option
jumper block on the upper right. It is backward to the sticker's layout,
but to me it makes more sense.
Terminator (I'll be baaack...)
Jumper to enable, open to disable termination.
Option Jumper Block
(1) Slot Enable Jumper
off: all three slots are active. Jumper on: only SmartMedia and
CF are active (type III slot is disabled). (Ed.
I think this is backwards - I jumpered mine and I can access all three
ports. Open, I saw only two, SM and CF)
(2-3) Vendor unique usage
(4) Firmware Write Enable Jumper
on: firmware rewrite mode. Jumper off: standard use. firmware cannot be
rewritten with jumper off. Jumper should remain off when the unit is in
'regular use'. Unit cannot function normally with this jumper on. Jumper
is only to be 'on' when rewriting firmware.
PCD-47B Weaknesses
First, the mounting
screw on the outer side of the front of the PCMCIA socket tends to come
loose and rattle about. Metal bit floating about inside of an enclosure
with energized parts...
Second - this mounting screw
is above the Compact Flash socket. Once this screw comes out, the metal
crossbrace under the PCB that it threads into may move out of alignment,
making it difficult to screw that side of the PCMCIA socket down. If the
crossbrace is hard to reach, you can detach the CF socket's black thermoplastic
cover with the two screws at the rear of the CF socket. Careful, leave
the white plastic part on the PCB!
Third - If you use
too long of a mounting screw on the front by the Compact Flash socket,
the CF card will never fully seat! Don't fret, there were six available
mounting holes to use. Five out of six ain't bad...
Complaints
The PCD-47B works far better than an MC-Disk. My issue
is that Microsoft NT4 won't let me rename the drive, so I see Removable
Drive (E:) and so on, but I'd like to see WHAT media the device is for
(PCMCIA, SM, CF)...
