INDUSTRIAL I/O PACK INTERFACE FEATURES

 

High density - Single-size, industry standard, IP module
footprint.

 

Local ID - Each IP module has its own 8-bit ID PROM which is
accessed via data transfers in the "ID Read" space.

 

16-bit I/O - Control register Read/Write and A/D
Conversion/Read are performed through 16-bit data transfer
cycles in the IP module I/O space.

 

High Speed - Access times for all data transfer cycles are
described in terms of "wait" states - (typically 0 to 3 wait states
are required for data transfer, see specifications for detailed
information).

 

Wait/Hold State Support - This IP module supports both
“wait” states (generated by the IP module) and “Hold” states
(generated by the carrier board).

SIGNAL INTERFACE PRODUCTS
(See Appendix for more information on compatible products)

This IP module will mate directly to any industry standard IP

carrier board (including Acromag AVME9630/9660 3U/6U non-
intelligent carrier boards).  Consult the documentation of your carrier
board to ensure compatibility with the following interface products
(since all connections to field signals are made through the carrier
board which passes them to the individual IP modules).

Cables:

Model 5025-551-X (Shielded Cable) or Model 5025-550-X (Non-
Shielded Cable):  A Flat 50-pin cable with female connectors at
both ends for connecting AVME9630/9660, or other compatible
carrier boards, to Model 5025-552 termination panels.  The
shielded cable is recommended for optimum performance with
precision analog I/O applications, while the unshielded cable is
recommended for digital I/O.

Termination Panel:

Model 5025-552:  DIN-rail mountable panel provides 50 screw
terminals for universal field I/O termination.  Connects to
Acromag AVME9630/9660, or other compatible carrier boards,
via flat 50-pin ribbon cable (Model 5025-550-X or 5025-551-X).

Transition Module:

Model TRANS-GP:  This module repeats field I/O connections
of IP modules A through D for rear exit from the card cage.  It is
available for use in 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 VMEbus mechanical dimensions, except for
shorter printed circuit board depth.  Connects to AVME9630/
9660 boards via a flat 50-pin ribbon cable within the card cage
(cable Model 5025-550-X or 5025-551-X).

INDUSTRIAL I/O PACK SOFTWARE LIBRARY

Acromag provides  an Industrial I/O Pack Software Library

diskette (Model IPSW-LIB-M03, MSDOS format) to simplify
communication with the board.  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 and the
“INFO320.TXT” file in the “IP320” subdirectory on the diskette for
more details.

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 board may be configured differently, depending on the

application.  All possible jumper settings will be discussed in the
following sections.  The jumper locations are shown in Drawing
4501-433.

Power should be removed from the board when configuring

hardware jumpers, installing IP's, cables, termination panels and
field wiring.  Refer to Drawing 4501-434 and IP documentation for IP
configuration and assembly instructions.
