INDUSTRIAL I/O PACK SERIES ACPC8625 CompactPCI BUS CARRIER BOARD
___________________________________________________________________________________________
- 3 -
Upon power-up the system auto-configuration process assigns
the carrier’s base address in memory space.
•
Plug-And-Play Interrupt Support - The personal computer
system software will allocate one interrupt line to the carrier.
The carrier’s interrupt pending register can be used to quickly
identify IP module pending interrupts.
•
Supports Two Interrupt Channels per IP - Up to two
interrupt requests are supported for each IP. Additional
registers are associated with each interrupt request for control
and status monitoring.
•
Full IP Register Access - Makes maximum use of logically
organized programmable registers on the carrier boards to
provide for easy configuration and control of IP modules.
Supports accesses to IP input/output, interrupt, and ID ROM
data spaces. No hardware jumper settings are required on the
carrier board.
•
IP Module Access Time Out - Allows access to empty IP
slots without system failure. If the IP module accessed does
not respond within 32u seconds the bus access is terminated
without system failure. This allows each IP slot to be probed to
determine if an IP is installed. A control register bit will be set
and/or issue of an interrupt request to indicate IP module time
out access has occurred.
•
LED Indicators Simplify Debugging - Front panel LED's are
dedicated to each IP module to give a visual indication of
successful IP accesses
•
Rear Backplane Connectors Access I/O - Rear backplane
connectors P4 and P5 access to field I/O signals mapped per
the IP on CompactPCI Specification (PICMG 2.4, R1.0). A
transition module (Acromag Model TRANS-C200) routes the
field I/O signals from P4 and P5 to the rear of the cage system
with separate SCSI-2 connectors for each IP module. All
SCSI-2 connectors can be connected with a standard SCSI-2
cable from the transition module without interference from
boards in adjacent slots. Spring latch hardware on the
transition module provides for excellent connection integrity and
easy cable removal.
•
Optional Screw Termination Panel - Model supports field
connection via screw terminals using the optional DIN rail
mount termination panel (Model 5028-182).
•
Supervisory Circuit for Reset Generation - A
microprocessor supervisor circuit provides power-on, power-
off, and low power detection reset signals to the IP modules per
the IP specification.
•
Individually Filtered Power - Fi5V, +12V, and -12V
DC power is provided to the IP modules via passive filters
present on each supply line serving each IP. This provides
optimum filtering and isolation between the IP modules and the
carrier board and allows analog signals to be accurately
measured or reproduced on IP modules without signal
degradation from the carrier board logic signals.
•
Individually Fused Power - Fused +5V, +12V, and -12V DC
power is provided. A fuse is present on each supply line
serving each IP module.
•
ESD Strip on ACPC8625 Board - The ACPC8625 board has
been designed to provide electrostatic discharge (ESD)
capability by using an ESD strip on the board per ANSI/VITA
1.1-1997 and IEEE1101.10.
•
Injector/Ejector Handles - The ACPC8625 uses modern
injector/ejector handles, which push the board into the rack
during installation and have a positive self-locking mechanism
so they cannot be unlocked accidentally. These handles are
fully IEEE 1101.10 compliant and are needed to give leverage
to install and remove the board.
•
EMC Front Panel - The ACPC8625 uses the preferred EMC
front panel per IEEE 1101.10 specification.
•
5 Volt CompactPCI Keying - The ACPC8625 implements a
keying mechanism to differentiate 5V or 3.3V signaling
operation. This board uses 5V signaling operation. The key is
inserted into the J1 connector. (Key Color: Brilliant Blue)
•
OLE Control Software is Available - Acromag provides
Object Linking and Embedding (OLE) controls software for
Windows 95/98/NT
TM
. This software (Model IPSW-OLE-PCI,
MSDOS format) provides individual drivers that allow IP
modules and Acromag personal computer carriers to be easily
integrated into Windows application programs, such as Visual
C++, Visual Basic, Borland Delphi
TM
, Microsoft
Office 97
applications, and others.
CompactPCI BUS INTERFACE FEATURES
•
Slave Module- All read and write accesses are implemented
as either a 32-bit, 16-bit or 8-bit single data transfer.
•
Immediate Disconnect on Read - The CompactPCI bus will
immediately disconnect after a read. The read data is then
stored in a read FIFO. Data in the read FIFO is then accessed
by the CompactPCI bus when the read cycle is retried. This
allows the CompactPCI bus to be free for other system
operations while the read data is moved to the read FIFO.
•
Interrupt Support - CompactPCI bus INTA# interrupt request
is supported. All IP module interrupts are mapped to INTA#.
Carrier board software programmable registers are utilized as
interrupt request control and status monitors.
SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)
This IP carrier board will mate directly to all industry standard 8
MHz IP modules. Acromag provides the following interface products
(all connections to field signals are made through the carrier board
and transition module which passes them to the individual IP
modules):
Cables:
Model 5028-187 (SCSI-2 to Flat Ribbon Cable, Shielded): A
round 50 conductor shielded cable with a male SCSI-2
connector at one end and a flat female ribbon connector at the
other end. The cable is used for connecting ACPC8625 with
the TRANS-C200, or other compatible carrier boards, to Model
5025-552 termination panels.
Termination Panel:
Model 5025-552: DIN-rail mountable panel provides 50 screw
terminals for universal field I/O termination. Connects to
Acromag ACPC8625 with the TRANS-C200, or other
compatible carrier boards, via SCSI-2 to Flat Ribbon Cable,
Shielded (Model 5028-187).
CompactPCI Transition Module:
Model TRANS-C200: This module plugs into the rear
backplane directly behind the carrier board. The field I/O
connections are made through the backplane to J4 and J5
connectors of the carrier board and then routed to four SCSI-2
connectors on the transition module (marked IP module slots “A
through D”) for rear exit from the card cage. It is available for
use in CompactPCI bus card cages which provide rear exit for
I/O connections via transition modules (transition modules can
only be used in card cages specifically designed for them). It is
a double-height (6U), single-slot module with front panel
hardware adhering to the CompactPCI Specification (PICMG
2.0, R2.1-1997) and IEEE Standard (1101.11-1998), with a
printed circuit board depth of 80mm, which is a standard
transition module depth. The transition module connects to
