The ICP Controller is designed for minimum power consumption and maximum operational
security. It therefore contains delicate electrical components (CMOS). In order to avoid
damages caused by electrostatic charges, the following warning must be observed during
installation:
Never take the ICP Controller out of the anti-static bag unless this is done at an anti-
static work place and the person handling the ICP Controller is secured against elec-
trostatic charge through wrist bands. If these instructions are not observed, the user
risks damage or destruction of the CMOS components of the ICP Controller !

Before installing, please switch off the complete computer system and remove all cables
including the power cable. Open the case of the host computer with an appropriate screw-
driver (usually a medium sized Philips screwdriver).

If the ICP Controller is not yet equipped with cache RAM, or if another SIMM is to be in-
stalled, we recommend adding it before you install the ICP Controller in your computer sys-
tem. As mentioned before, the ICP Controller can be run with different cache RAM sizes.
The minimum cache RAM size is 4MB.The maximum cache RAM size is 64MB. The ICP
Controller provides one socket for a standard 72 PIN SIMM (Single Inline Memory Module).
The SIMM can either have parity (=36 Bit), or non-parity (=32 Bit). The ICP Controller's
memory controller can use a Fast Page Mode (FPM) SIMM with 60ns (or less) or an Ex-
tended Data Out (EDO) SIMM with 50ns. The use of an EDO SIMM increases the perform-
ance of the ICP Controller. The SIMM is correctly plugged into the SIMM socket if it is
engaged correctly into the socket's metal hooks and if all contacts of the SIMM are equally
contacting the corresponding pins of the socket.
Automatic Cache RAM Recognition
Each time you switch on the computer system, the ICP Controller automatically recognizes
how much cache RAM is available and configures itself accordingly.

Recommended SIMM Manufacturers
SIMMs from Goldstar, Motorola, NEC, Samsung, Siemens, Texas Instruments, and Toshiba
have been successfully tested with the ICP Controllers. This recommendation does not im-
ply an evaluation of quality. SIMMs from other manufacturers may be equally suitable. You
can use single- and double-sided SIMMs. When using double-sided SIMMs with high power
consumption special care should be taken that both, the ICP Controller and SIMM are
properly cooled.
SIMM sizes and types which can be used on the ICP Controller :
Fast Page Mode (FPM) SIMM,
60ns (or less), Jumper S1 not set Extended Data Out (EDO) SIMM, 50ns (*),Jumper S1 set RAM Size
1M*32 and 1M*36 1M*32 and 1M*36 4MB
2M*32 and 2M*36 2M*32 and 2M*36 8MB
4M*32 and 4M*36 4M*32 and 4M*36 16MB
8M*32 and 8M*36 8M*32 and 8M*36 32MB
16M*32 and 16M*36 16M*32 and 16M*36 64MB
(*) When using an EDO SIMM on the ICP Controller, jumper S1 has to be set (see next page).
For the operation of a Fast Page Mode SIMM S1 must remain open. We have tested several
EDO SIMMs with 60ns without any problems, but according to the specification of the ICP
Controller's Intel i960 CPU, 50ns are necessary to comply with the timing requirements.
There is a 16MB SIMM available which allows an online DRAM Error Correction (ECC). For
further details on this SIMM and the 50ns EDO SIMMs, contact your ICP vortex representa-
tive or check our Website (http://www.icp-vortex.com).
Obviously, the question arising at this point is: "How much cache RAM do I need ?"
In the following table, we made RAM equipment suggestions for the minimum, typical and
optimum RAM size (Note: Naturally, all ICP Controllers work flawless with the smallest RAM
size stated in column 2 of this table).

It is very important for you to observe the information and notes given in this section of the
User’s Manual because it helps to ensure that the SCSI devices that are used in connection
with the ICP Controllers are operated in a successful, long-lasting and trouble-free manner.

In many cases, this information is not only applicable to ICP Controllers, but in general to
all those SCSI systems which, like the ICP Controllers, use Single Ended SCSI bus channels.
According to its definition, the SCSI bus provides access to several participants that are
physically connected through an appropriate SCSI bus cable. To achieve a sufficiently good
signal quality, it is not only recommended to use very good cables and connectors, but also
to terminate both ends of the cable properly. For an unambiguous identification on the bus,
all participants have a unique number – the so-called SCSI-ID. Further details on these
topics can be found on the following pages.
Please note that 98% of all SCSI-related problems are caused by bad SCSI cables,
wrong SCSI bus termination and duplicate SCSI-IDs.
Recently, strong efforts have been made to automate the setting of the SCSI bus termina-
tion and SCSI-ID on the SCSI bus. An appendix to the SCSI-3 specification with the title
SCAM (SCSI Configured AutoMatically) has been created. It includes a description of all the
functions necessary for building a SCAM compatible SCSI device or controller. Unfortu-
nately, in real life SCAM is rather a definition than a useful help. Even worse, SCAM has
added other problems and more confusion to the already difficult SCSI topic. As long as it
is possible to buy and operate SCSI devices without the SCAM feature (99.9% of all cur-
rently available devices do not support SCAM), massive problems are very likely to occur.
Therefore, the ICP Controllers only rely on the well proven and standard method of setting
SCSI-IDs and SCSI bus terminations and do not expect any further capabilities of the SCSI
devices.

The quality and overall length of the cable, as well as the number and quality of the SCSI
connectors is very important for both internal and external SCSI cables. Generally, internal
SCSI cables are 50 or 68 conductor flat ribbon cables. To connect external SCSI devices,
round and shielded cables with appropriate connectors are typically used. The minimum
cross section per line has been defined in the SCSI-3 specification as follows:
50 conductor cables: minimum 28 AWG conductors and with
68 conductor cables: minimum 30 AWG conductors.
The typical impedance of a SCSI cable is 84 Ohm +/- 12 Ohms. The maximum difference in
impedance between two conductors of a SCSI cable must not exceed 12 Ohms. External
round cables should have a SCSI-compliant placement of the inside conductors. Besides
the cables, the right connectors for a cable are also very important. It is highly recommend
to use highest quality connectors, only. The following table shows the maximum cable
lengths allowed for a given transfer rate. Based on many years of SCSI experience, the
lengths we recommend are in some cases shorter than theoretically possible. The informa-
tion in the table refers to one SCSI channel and represent the overall length of the cable,
including internal and external parts.

With regard to Fast-20 devices, the maximum number of participants and the maximum ca-
ble length have to be strictly observed when a Fast-20 device (even if it is only one) is run-
ning in Fast-20 mode. In each case , the minimum cable length is 0.5 m. In addition to
specifications mentioned above, the following should be kept in mind when selecting and
installing SCSI cables:
Always install SCSI cables that are as short as possible. The lengths in the table above
are absolute maximum lengths. (Total length of internal and external cables per chan-
nel).
Avoid using SCSI cables with more connectors than actually needed. Never select a SCSI
mode or operate a SCSI device with a cable that is not appropriate for this mode.
The minimum distance between two connectors of a SCSI cable is 20 cm.
Avoid cable stubs. If this is not possible, keep the stub length below 10 cm.
“Star cablings” are not allowed.
Keep the number of transitions from flat to round cables and vice versa as small as pos-
sible. It is usually best is to use flat or round cables, only.
Check these points when routing SCSI cables:
- Avoid kinks in the SCSI cable
- Do not roll the SCSI cable up on itself
- Avoid routing the cable next to other cables
- Avoid routing the cable in the vicinity of noise sources such as power supplies
- Avoid routing the cable over sharp edges and in areas where it could get caught up
- Avoid routing/sticking the cable directly onto metal surfaces
Below is a list of some manufacturers of high quality SCSI connectors and cables: 3M, AMP,
Amphenol, Fujitsu, Harting, Honda, Methode, Molex, Robinson Nugent, Yamaichi.
When making home-made SCSI cables, make sure that the insulation displacement connec-
tors are properly aligned and firmly pressed into the flat ribbon cable. Otherwise, the whole
cable might turn out to be a big short-circuit. Furthermore, check carefully that PIN 1 of the
cable connects to PIN 1 of the connectors. A simple short-circuit and continuity test before
running the devices helps you to save time and money.
The same warnings as for home-made cables apply when you buy non-brand cables. If you
plan to run Fast-20 devices, you should explicitly ask your dealer if these cables are appro-
priate for the Fast-20 mode. (Note: The ICP product range also includes some high quality
SCSI accessories. Along with external SCSI brackets, there is a special FAST-20 Wide SCSI
cable. Please see section B.4.4 of this User's Manual or check our Website: http://www.icp-
vortex.com, for further details).

In order to ensure a flawless and interference-free signal transmission on the SCSI bus and
to minimize the detrimental effects of external noise generators, both ends of the SCSI ca-
ble have to be terminated. The SCSI specification prescribes two alternative termination
modes for Single-Ended SCSI bus systems: the passive termination and the active termina-
tion, also known as Alternative-2 termination. The passive termination consists of a 220
Ohm pull-up and a 330 Ohm pull-down resistor for each signal. Today, the passive termina-
tion is mostly used in systems with synchronous data transfer rates not exceeding 5 MB/sec,
which is rather slow. The active termination circuit consists of a 110 Ohm precision-resistor
per signal and a common 2.85Volt voltage regulator. Thus, all signals are actively pulled up
to a certain level. The active termination provides much better signal quality and signifi-
cantly reduced liability to noise. All ICP Controllers are equipped with an active SCSI bus
termination. The voltage for the termination circuitry (passive and active) is supplied either
by the SCSI device itself, or by the TERMPWR line of the SCSI bus. Every SCSI device, re-
gardless of whether it is a hard disk, a printer, or a ICP Controller, must have a SCSI bus
termination. In addition, it must be possible to enable and disable the SCSI bus termina-
tion (on some devices, resistor array packs or a jumper have to be removed, on others, like
the ICP Controllers, soft-switches allow a very comfortable setting of the SCSI bus termina-
tion). Furthermore, on each SCSI device it must be possible (for example through a jumper)
to switch the voltage on the terminator power line (TERMPWR) of the SCSI cable on or off.
For all configurations with ICP Controllers, we recommend that you use exclusively SCSI
devices with an active SCSI bus termination:
Always use active SCSI bus termination.
Do not use SCSI devices with passive SCSI bus termination (e.g., CD-ROMs) for the ter-
mination of the SCSI cable.
Always terminate only the two ends of a SCSI cable.
The TERMPWR jumpers on the ICP Controller PCB (per channel, one) should always be set.
In this way, it is the ICP Controller which supplies the termination power on the SCSI cable
and no other SCSI device may supply termination power on the cable.
With regard to a proper termination in SCSI configurations comprising of ICP Controllers,
SCSI devices, and SCSI cables, it is appropriate to go into further detail.
This already difficult topic is further complicated by the fact that for each SCSI channel, the
1, 2, and 3 channel Wide SCSI or Wide & Ultra SCGDTICP Controllers have a dual connector
system. ICP provides both a standard 50 pin header and a 68 pin receptacle. This is an
enormous advantage of ICP products; firstly, because you do not have to spend your money
on expensive adapters, second, because it offers you more connections. To make things
even more sophisticated, there is an external 68 pin connector for channel A (in fact, there
are three connectors for channel A on the controller !). The only secure way of finding out
which particular connector to use and which terminator to enable is by analyzing the table
below.
Note: To enable the option Auto (available for channel A only), or toggle between the ON
and OFF termination settings for a ICP Controller SCSI channel, use the Configure Controller
menu in GDTSETUP.
The connections listed in the table below are the only valid connections allowed. Any other
connection setup, even if physically possible, is not allowed as it will cause serious mal-
functions or even the destruction of the SCSI devices and/or the ICP Controller.

All participants on the SCSI bus must have a unique identification number, that is, each
number can only be used once on a given cable. Each SCSI device is uniquely addressed
through its SCSI ID.
All participants of a SCSI bus must have a different SCSI ID.
The factory set SCSI ID of the ICP Controller SCSI channel is 7.
Up to 7 SCSI devices can be connected to a single SCSI bus. SCSI IDs are 0 to 6.
On hard disks, CD-ROMs, tape streamers, etc., the SCSI ID is normally set through jumpers
or small GDT switches. The ICP Controllers offer a far more comfortable method: software
switches in the GDTSETUP program allow you to easily set the SCSI ID of a GDT SCSI chan-
nel. It is recommended to leave the default ID value at 7. Some operating systems require
that the SCSI ID of certain SCSI device (e.g., tape streamer, CD-ROM) is set to a particular
value (for more information, please refer to the appropriate chapter in this manual).
(Note: More than 7 SCSI devices on a 16 Bit cable represent a performance bottle-neck for
disk arrays. The SCSI bus utilization is too high).

Make sure that the ICP Controller is equipped with an appropriate SIMM. As already men-
tioned in section B.3 of this User's Manual it is not possible to operate the ICP Controller
without a SIMM.
Step 1
Switch off the PCI computer system and remove all cables (first of all the power supply).
Step 2
Following the instructions in the computer manual, open the case of the PCI computer, so
that you have easy access to the PCI expansion slots.
Step 3
Select a free PCI bus-master slot and remove the metal bracket, following the instructions
in your PCI computer manual. It is essential that the ICP Controller is plugged into a bus-
master slot (it will NOT work in a slave or non-bus-master slot). Some motherboards have
only 1 bus-master slot.
Make sure that the selected slot has a sufficiently cooling airflow. Permanent overheating of
electronic devices decreases their life time drastically.
Step 4
Channel A of the ICP Controller has an internal and an external SCSI connector. If you wish
to connect SCSI devices to the internal as well as to the external SCSI connector of channel
A, disable the SCSI-bus termination of channel A by means of the GDTSETUP program (see
later on in this chapter). The SCSI-bus termination of the different SCSI channels of your
ICP Controller can be enabled or disabled through software-switches within the central
setup utility program GDTSETUP. When changing the SCSI-bus termination, the ICP Con-
troller can remain in the computer.
Step 5
Push the ICP Controller firmly into the correct PCI bus-master slot. Make sure that the con-
troller fits tightly into it, and that the external SCSI connector sticks out of the computer
case. Now, fix the ICP Controller by tightening the screw of its bracket.
Step 6
To connect internal SCSI devices, use the internal SCSI connectors of the ICP Controller (2,
or 3). You need 50-pin or 68-pin SCSI flat ribbon cables with appropriate connectors. Please
verify that the colored core of the SCSI flat ribbon cable connects PIN1 of the GDT SCSI
connector to PIN1 of the SCSI device. To connect an external SCSI device, an external round
cable is needed. Please make sure that the total length does not exceed the limits which are
determined by mode and transfer rate. Regardless of whether the SCSI devices are con-
nected to the internal or the external SCSI connectors of the ICP Controller, you should only
use cables of highest quality in order to ensure an interference-free data transfer. Double-
check that no other SCSI device has its SCSI-ID set to 7, as this is the SCSI-ID of the ICP
Controller (= SCSI IDentification number, assuming values between 0 and 7). If neces-
sary, the ID of the GDT SCSI channels can be changed with the GDTSETUP program (see
later in this chapter). The SCSI-ID can be chosen directly on the SCSI device by setting DIP
switches or jumpers (please refer to the manual of the SCSI device). Furthermore, all SCSI
devices connected to a given SCSI channel must have different SCSI-IDs. Additionally, it is
important that the SCSI terminators are removed or switched off when more than one SCSI
device is operated together with the ICP Controller. Only the last and the first participant of
a SCSI channel (i.e., the two ends) may have SCSI terminators whereas all other participants
on the SCSI bus must have their terminators removed or - if possible - switched off. The


&KDSWHU%+DUGZDUH,QVWDOODWLRQ
jumpers TPA, TPB or TPC (= terminator power) on the ICP Controller are usually set. This
setting may only be modified if the terminator power on the SCSI cable is supplied by an-
other SCSI device. The terminator power line on the SCSI cable may be used by SCSI de-
vices which do not supply DC power to their own SCSI termination circuitry (e.g., external
SCSI terminator packs.).
Step 7
When installing internal SCSI devices, make sure that the slots of the SCSI devices have
sufficient air flow, and that the power consumption of all SCSI devices does not exceed the
capacity of the computer's power supply. An overloaded DC power supply has a poor DC
voltage quality (noise, ripple) and causes problems for all connected consuming devices.
Step 8
If required, you can connect the HDD-front-LEDs of the PCI computer system to the LED
connectors of the ICP Controller (for the pin assignment of these connector, see the appen-
dix).
Step 9
Before the PCI computer system is switched on, you should check the following points over
again:
99Is the SIMM plugged firmly into the SIMM socket ?
99Is the ICP Controller plugged firmly into one of the PCI bus-master slots ?
99Are the SCSI-IDs set correctly ?
(with no other device currently set to ID 7 ?)
99Are the SCSI-bus terminators plugged/set correctly ?
(with currently terminated GDT SCSI channels ?)
99Are the SCSI flat ribbon cables connected correctly ?
99Are all SCSI devices installed properly and connected to the power supply
of the PCI computer system ?
Step 10
After having checked all the points in "Step 9", reconnect the PCI computer system to the
power supply. Do not close the computer case yet.

Before we put the ICP Controller into operation for the first time, we would like to spend a
few words on the PCI 2.x compatibility requirements a PCI computer system (especially the

A pre-condition for a flawless installation of PCI bus-master expansion cards (the ICP Con-
trollers belong to this group of expansion cards) in a PCI motherboard is a 100% PCI 2.x
compatible System-BIOS.

We have observed more than once that a motherboard declared fully PCI 2.x compatible
was equipped with a System-BIOS (located in an EPROM or FLASH-RAM) which was not
PCI 2.x compatible at all. To make up for this, many manufacturers of PCI motherboards or
PCI computer systems offer their customers a BBS mailbox system from where the latest
PCI-system-BIOS version can be downloaded by modem.
As PCI is a rapidly growing market and more and more bus-master expansion cards (high
performance disk and LAN controllers) are becoming available, we have no doubt that such
problems will be resolved very quickly by the respective system-BIOS manufacturer.
The System is fully PCI compatible.
If your PCI motherboard/computer is 100% PCI compatible, its PCI system-BIOS will, to a
large extent automatically (plug & play), carry out the configuration (e.g., mapping of the ICP
Controller's BIOS and DPMEM, assignment of a proper system IRQ to a PCI interrupt). This
means that the PCI computer system (with its motherboard and PCI system-BIOS) must
meet the following requirements:
1. The PCI computer system must automatically assign (map) the ICP Controller BIOS to
an adequate address in the lower, 1MB area of the computer system’s main memory.
2. The PCI computer system must map the ICP Controller’s Dual Ported Memory (needed
for high performance operation) to an adequate address in the lower, 1MB area of the
computer system’s main memory. In addition, it has to disable the shadowing of this
address <SPACE>.
3. Assigning a system IRQ to a PCI interrupt.
The PCI 2.x specification prescribes 4 PCI interrupts, called INT A, INT B, INT C and
INT D. A PCI interrupt must be assigned to a free (unused) IRQ of the PCI mother-
board or computer. The ICP Controller is shipped with PCI INT A.
Depending on the manufacturer of the PCI computer system, there are several ways to
carry out this task:
automatically (automatic IRQ routing)
with the PCI System-BIOS setup program
with the PCI System-BIOS setup program and
jumper settings on the system motherboard
Depending on the BIOS manufacturer (e.g., Award, Phoenix, AMI etc.), the setup pro-
gram is activated by pressing a certain key-combination shortly after the reset (cold
boot or warm boot). For detailed information on the key-combination and the jump-
ers’ locations and settings, please refer to the system manual of your PCI mother-
board or computer.
The System is not fully PCI compatible.
Problems may occur if the motherboard and/or System-BIOS are not fully PCI 2.x compati-
ble. The best remedy is to update the PCI system-BIOS to the latest version.
Furthermore, we have integrated into our GDT BIOS various routines (tricks) which remedy
the incompatibilities of some PCI system-BIOSes, at least with regard to the ICP Controller.

Now, after having installed the ICP Controller and the SCSI devices, check whether the con-
troller is working correctly. If the ICP Controller is the only controller in the computer sys-
tem, set hard disks C: and D: to not available in the System-BIOS setup program of the
