DETAILS ABOUT ARTIC CARDS
ARTIC
Installation Worksheets
ARTIC Hardware
Configuration
Some
hardware configuration is required before an ARTIC may be used in your
system. Depending on the ARTIC model, this configuration is accomplished
through the use of jumpers and switches, or by running the PS/2
Reference Disk.
 The
ARTIC typically uses an 8K page window on the computer bus. When you
choose an address range for the ARTIC window, you must avoid memory
conflicts with other adapter cards in the computer. This worksheet is
provided to assist in determining a free 8K page window. To help you,
there is a Memory Map table of addresses commonly used by other adapters
near the end.
ARTIC
Multiport Model II and
ARTIC X.25 Interface Co-Processor
Quadron
recommends the following switch settings for the ARTIC Multiport Model
II and ARTIC X.25 Interface Co-Processor. Refer to the Realtime
Interface Co-Processor Guide to Operations supplied with your ARTIC
for detailed jumper information.
- Bus-Width
switch BW must be set for "8-Bit Bus".
- If
interrupt levels greater than 9 are selected, "Co-Processor In
Two Edge Expansion Slot" must be selected for switch ED. The
ARTIC must also be installed in a 16-Bit slot. If interrupt levels
less than 10 are selected, either "Two Edge" or "One
Edge" can be selected and the ARTIC can be installed in either
a 16-Bit or 8-Bit slot respectively.
Use the
Adapter RAM Worksheet later on this page to select an appropriate 8K
page window. There are no switch settings required to select the 8K page
window.
ARTIC
Portmaster
Quadron
recommends the following configuration for the ARTIC Portmaster. Refer
to the Realtime Interface Co-Processor Guide to Operations
supplied with your ARTIC adapter for detailed configuration information.
- Shared
Storage Location & Size must specify a window size of 8K. For
DOS, the 8K window must be below 1 megabyte. For OS/2, the 8K window
can be located above or below 1 megabyte.
Shared Storage Window

ARTIC
Multiport/2 and ARTIC X.25 Interface Co-Processor/2
Quadron
recommends the following configuration for the ARTIC Multiport/2 and
ARTIC X.25 Interface Co-Processor/2. Refer to the Realtime Interface
Co-Processor Guide to Operations supplied with your ARTIC for
detailed configuration information.
- Shared
Storage Location & Size must specify a window size of 8K. For
DOS, the 8K window must be below 1 megabyte. For OS/2, the 8K window
may be located above or below 1 megabyte.

If
Ports 0 and 1 are being used for ASYNCHRONOUS communications only,
configure the clocking options to one of the following depending on the
Option Diskette supplied with your ARTIC:
Port 0 Clocking
Options.................[DPLL Clk/32; Loc. RX Clk; DCE]
Port 1 Clocking Options.................[DPLL Clk/32; Loc. RX Clk; DCE]
-
or -

Port 0 Receive Clock Source.............[DPLL Clk/32 Local Clocking]
Port 1 Transmit Clock Source............[DCE source clocking]
Port 1 Receive Clock Source.............[DPLL Clk/32 Local Clocking]
ARTIC Dual
Port and
ARTIC Multiport
(both have been discontinued)
Quadron
recommends the following jumper settings for the ARTIC Dual Port and
ARTIC Multiport. Refer to the Realtime Interface Co-Processor Guide
to Operations supplied with your ARTIC for detailed jumper
information.
- Bus-Width
jumpers JRA/JRB/JRC-BW must be set for "8-Bit Bus."
- If
interrupt levels greater than 9 are selected, "Co-Processor In
Two Edge Expansion Slot" must be selected for jumpers JRA/JRB/JRC-ED
and JP12. The ARTIC must also be installed in a 16-Bit slot. If
interrupt levels less than 10 are selected, either "Two
Edge" or "One Edge" can be selected and the ARTIC can
be installed in either a 16-Bit or 8-Bit slot respectively.
Use the
Adapter RAM Worksheet later on this page to select an appropriate 8K
page window. There are no jumper settings required to select the 8K page
window.
ARTIC Interrupt
Levels
The ARTIC
may be configured to run on various hardware interrupt levels. ARTICs
are designed to share a common interrupt level. Since many non-ARTIC
hardware adapters do not support interrupt sharing, Quadron recommends
that all ARTIC adapters be placed on a common interrupt level that is
not used by any non-ARTIC adapter. Depending on the other adapters
installed in your system, Interrupt Requests (IRQs) 10, 11 or 12 are
often unused. Refer to the Interrupt Level Selection tables later on
this page for some IRQ levels commonly used by other adapters in your
computer.
ISA Bus ARTIC 8K

The
remainder of this section contains two sample worksheets for use with
ISA bus systems. You should make your own worksheets and fill in the
empty spaces according to the following steps, referring to the sample
worksheets for guidance.

How to Select an
Interrupt Level
What
interrupt level should I configure the ARTIC card on?
The
ARTIC card can be configured to operate on any hardware interrupt
request (IRQ) level. The ARTIC card and its software both support shared
interrupts. Even though some non-ARTIC hardware adapters support
interrupt sharing, their supporting software often does not. Quadron
recommends that you place all ARTIC adpaters on a common IRQ level that
is not shared by any non-ARTIC adapter.
To assist
you in configuring the ARTIC interrupt level, here are two lists of
adapters and their interrupt levels. The lists have the same data, but
the first is alphabetical by adapter name, and the second is numerical
by Interrupt Request level.
