2.0 PREPARATION FOR USE
UNPACKING AND INSPECTION
Upon receipt of this product, inspect the shipping carton for
evidence of mishandling during transit. If the shipping carton is
badly damaged or water stained, request that the carrier's agent
be present when the carton is opened. If the carrier's agent is
absent when the carton is opened and the contents of the carton
are damaged, keep the carton and packing material for the
agent's inspection.
For repairs to a product damaged in shipment, refer to the
Acromag Service Policy to obtain return instructions. It is
suggested that salvageable shipping cartons and packing
material be saved for future use in the
event the product must be shipped.
This board is physically protected with
packing material and electrically protected
with an anti static bag during shipment. It
is recommended that the board be visually
inspected for evidence of mishandling prior
to applying power.
The board utilizes static sensitive
components and should only be handled at
a static-safe workstation.
CARD CAGE CONSIDERATIONS
Refer to the specifications for loading and power
requirements. Be sure that the system power supplies are able
to accommodate the power requirements of the carrier board,
plus the installed IP modules, within the voltage tolerances
specified.
IMPORTANT: Adequate air circulation must be provided to
prevent a temperature rise above the maximum operating
temperature.
The lack of air circulation within the computer chassis is a
cause for some concern. Most, if not all, computer chassis do
not provide a fan for cooling of add-in boards. The dense
packing of the IP modules to the carrier board alone results in
elevated IP module and carrier board temperatures, and the
restricted air flow within the chassis aggravates this problem.
Adequate air circulation must be provided to prevent a
temperature rise above the maximum operating temperature and
to prolong the life of the electronics. If the installation is in an
industrial environment and the board is exposed to environmental
air, careful consideration should be given to air-filtering.
BOARD CONFIGURATION
The carrier board is plug-and-play compatible and, as such,
its board addresses are automatically assigned by the system
auto-configuration routine upon power-up. The base address of
the carrier board’s configuration registers in memory space and
I/O space is assigned. In addition, the base addresses of the IP
modules and carrier board registers are assigned in 32-bit
memory space.
Power should be removed from the board when changing
jumper configurations or when installing IP modules, cables,
termination panels, and field wiring. Refer to Mechanical
Assembly Drawing 4501-672 and your IP module documentation
for specific configuration and assembly instructions.
IP Memory Space Configuration
A configuration jumper must be set on the carrier, prior
to power-up, to enable
IP Memory Space.
Setting this jumper
will allow each IP module to use up to 8M bytes of Memory
Space. Note that the board will request 64M bytes of system
memory during PCI configuration. This value cannot be altered.
See diagram 4502-114 located in the drawings portion of this
manual for jumper location and settings.
The jumper must be
present in one of the two configurations for proper board
operation. Factory default is memory space disabled.
Interrupt Configuration
No hardware jumper configuration is required for interrupts.
Interrupt enables and status flags are configured or viewed via
programmable registers on the carrier board (see Section 3 for
programming details). The carrier board passes interrupt
requests from the IP modules to the PCI bus. Refer to the IP
modules for their specific configuration requirements.
CONNECTORS
Connectors of the APC8640 carrier consist of five carrier IP
module field I/O connectors, five IP module logic connectors, and
one PCI bus interface connector. These interface connectors are
discussed in the following sections.
Carrier Field I/O Connectors (IP modules A through E)
Field I/O connections are made via 50 pin 3M ribbon cable
connectors A, B, C, D, and E for IP modules in positions A
through E. IP module assignment is marked on the board for
easy identification (see IP location drawing 4502-114 for physical
locations of the IP modules). Flat cable assemblies and
termination panels (or user defined terminations) can be quickly
mated to the field I/O connectors. Pin assignments are defined
by the IP module employed since the pins from the IP module
field side correspond identically to the pin numbers of the 50 pin
connectors.
Carrier field I/O connectors A through E are 3M Low Profile
50-pin headers (3M P/N P50LE-050P1-R1-DA) and they mate to
ejector equipped ribbon cable connectors (P25LE-050S-DA).
