modules. IP Modules are available from Acromag and other
vendors in a wide variety of Input/Output configurations to meet
the needs of varied applications.
•
Provides Full IP Data Access - Supports accesses to IP
input/output, memory, identification data, and interrupt spaces.
•
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.
•
VME64 & VME64x CR/CSR Space – Configuration ROM /
Control & Status Register (CR/CSR) space provides additional
carrier board identification & programming capabilities. These
include software selection of the base address and address
modifier of the carrier card in the short I/O space.
•
VME64x Geographical Addressing – Supports the six
Geographical Addressing signals provided by VME64x
backplanes. These signals control the base address of the
CR/CSR space of each installed carrier. This provides
unambiguous identification of each carrier’s location within the
VME64x chassis.
•
No Hardware Jumpers or Switches – The board is fully
configurable via control registers.
•
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
connector P2 & P0 access to field I/O signals mapped per the
VME64x IP I/O (ANSI/VITA 4.1-1996) specification.
•
Memory Space Access Support - IP memory space
accesses are supported and software configurable from
1Mbyte to 8Mbytes in the VME64x bus standard address
space.
•
Supports Two Interrupt Channels per IP - Up to two
interrupt requests are supported for each IP. The VME64x bus
interrupt level is software programmable. Additional registers
are associated with each interrupt request for control and
status monitoring.
•
Interrupt Priority Control - Interrupts use a proirity shifting
scheme based on the last interrupt serviced. This prevents the
continuous interrupts of one IP module interrupt request from
blocking the interrupts of other IP modules.
•
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 signal noise.
•
ESD Strip - The AVME9675 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 AVME9675 uses modern
injector/ejector handles, which push the board into the rack
during installation and pull the board out of the rack for removal
or replacement. These handles are needed to give you
leverage to install and remove the board.

Slave Module-
CR/CSR Registers A24, D16/D08(O)
Carrier Register Short I/O Access A16, D16/D08(O)
IP Module ID Space A16, D16/D08(O)
IP Module I/O Space A16, D16/D08(EO)
IP Module Memory Space A24, D16/D08(EO)
•
Supports Short I/O Address Modifiers - Supports short I/O
(A16) address modifiers 29H, 2DH (H = Hex). Short I/O space
is used for carrier registers and IP module I/O and ID spaces.
The carrier board base addresss and short I/O address
modifier is set within the Function 0 Address DEcoder
CompaRe register (ADER) in CR/CSR space and decoded on
1K byte boundaries.
•
Supports CR/CSR Space Address Modifier – Supports
address modifier 2FH (H = Hex). CR/CSR space is used to
establish initial module communication, identification, location
(via geographic address), module base address, address
modifier and additional configuration parameters.
•
Supports Standard I/O Address Modifiers - Supports
standard (A24) address modifiers 39H, 3DH (H = Hex).
Standard address space is used when an IP supports memory
space. The carrier board is configured using programmable
registers to set the IP starting address and size (1Mbyte to
8Mbytes).
•
Supports Read-Modify-Write Cycles - Carrier board
supports VME64x bus read-modify-write cycles.
•
Interrupt Support - I(1-7) interrupter D16/D08 (O). Up to two
interrupt requests are supported for each IP module. The
VME64x bus interrupt level is software programmable. Carrier
board software programmable registers are utilized as interrupt
request control and status monitors. Interrupt release
mechanism is Release On Register Access (RORA) type.
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 AVME9670 or
AVME9675 with the TRANS-200, 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 AVME9670 or AVME9675 with the TRANS-200, or
other compatible carrier boards, via SCSI-2 to Flat Ribbon
Cable, Shielded (Model 5028-187).
VME64x Transition Module :
Model TRANS-200: This module plugs into the rear backplane
directly behind the carrier board. The field I/O connections are
made through the backplane to P0 (AVME9670 & AVME9675-4)
and P2 (AVME9670, AVME9675-2 & AVME9675-4) connectors of
the carrier board and then routed to four (two AVME9675-2) SCSI-2
connectors on the transition module (marked IP module slots “A
through D”) or (“A through B” for AVME9675-2) for rear exit from the
card cage. It is available for use in VME64x 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
