INDUSTRIAL I/O PACK SERIES AVME9675 VME64x 6U CARRIER BOARD
___________________________________________________________________________________________
- 4 -
hardware adhering to the VME64x bus mechanical dimensions 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 Acromag Termination Panel (Model 5025-552)
using SCSI-2 to Flat Ribbon Cable, Shielded (Model 5028-187) to
the rear of the card cage, and to AVME9670, AVME9675-2 &
AVME9675-4 boards within the card cage.
INDUSTRIAL I/O PACK SOFTWARE LIBRARY
Acromag provides an Industrial I/O Pack Software Library diskette
(Model IPSW-LIB-M03-1.44MB, MSDOS format) to simplify
communication with Acromag IP modules. All functions are written
in the “C” programming language and can be linked to your
application. Refer to the “README.TXT” file in the root directory on
the diskette for more details and the “info9675.TXT” files of the
“AVME9675” subdirectories that correspond to your carrier model.
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 dense packing of the IP modules to the carrier board
restricts air flow within the card cage and is cause for concern.
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 may be configured for different applications.
Configuration options will be discussed in the following Sections.
The IP module positions are shown in Drawing 4501-800. Power
should be removed from the board when installing IP modules,
cables, termination panels, and field wiring. Refer to Mechanical
Assembly Drawing 4501-801 and your IP module documentation for
specific configuration and assembly instructions.
VME64x INTERFACE CONFIGURATION
The carrier board is shipped from the factory configured as
follows:
•
Carrier board will respond to address modifier 2FH for
CR/CSR standard (A24) address space access. Base
address of the CR/CSR space is located in the CR/CSR Base
Address Register (BAR). Geographic addressing (per the
VME64x specification) is used to set the CR/CSR base
address and also to determine the active CR/CSR card
locations within the VME64x chassis.
•
Carrier board must be programmed with the Short I/O base
address and address modifier within the Function 0 Address
DEcoder CompaRe (ADER) Register in CR/CSR space to
define the base address of the AVME9675 carrier & IP module
registers.
•
Programmable Bit Set Register in the CR/CSR defaults to
Short I/O accesses disabled. Once enabled via the Bit Set
Register the board will respond to address modifier 29H or
2DH, as programmed in the ADER. Registers on the carrier
board plus the I/O and ID spaces on any installed IP modules
will then become accessible.
•
Programmable software registers default to IP memory space
(VME64x bus standard address space) accesses disabled.
•
Programmable software registers default to IP interrupt
requests-disabled and VME64x bus interrupt level-none.
Address Decode Configuration
There are no address jumpers or switches on this board. All
configuration takes place via control registers. Initial communication
with the carrier must be made to the CR/CSR space using
geographic addressing per the VME64x specification. The VME64x
backplane applies six geographic address signal lines to the P1
connector as listed in Table 2.1:
