External Trigger Input/Output
As An Input:..................…............Must be an active low 5 volt logic
TTL compatible, debounced signal
referenced to digital common.
Conversions are triggered within
6.4
μ
seconds of the falling edge.
Minimum pulse width 125n sec.
Maximum pulse width 6
μ
seconds,
otherwise, an additional trigger is
produced.
As An Output:............…..….........Active low 5 volt logic TTL
compatible output is generated.
The trigger pulse is low for
125n seconds, typical. A
maximum of 4 loads are allowed.
PCI Local Bus Interface
Compatibility......................…..... Conforms to PCI Local Bus
Specification, Revision 2.2 and
PMC Specification, P1386.1/Draft
2.4. (See Note 6)
Electrical/Mechanical Interface... Single-Width PMC Module.
PCI Target ……………………… Implemented by Altera FPGA.
4K Memory Space Required…… One Base Address Register.
PCI commands Supported…….. Configuration Read/Write,
Memory Read/Write, 32,16, and 8-
bit data transfer types supported.
Signaling………………………… 5V Compliant, 3.3V Tolerant.
PCI bus Write Cycle Time
5
…… 150 nS Typical measured from
falling edge of FRAME# to the
falling edge of TRDY#.
PCI bus Read Cycle Time
5
…… 150 nS Typical.
Notes (PCI Local Bus Interface):
5. Although the typical read or write PCI bus cycle time is only
150 nS the actual read or write implemented on the PMC Module
will be typically 1000 nS. Thus, the PMC Module will issue a
RETRY when a new read or write cycle is implemented before
the PMC module’s 1000 nS read or write has completed. When
the PMC Module issues a RETRY this frees the PCI bus while
the previous read or write operation is completed.
6. Due to the unique modular nature of the PMC230 assembly, it is
impossible to comply with the solder side component height per
the PMC Mechanical Standand. Refer to Mechanical Assembly
Drawing 4501-859 for details. You must determine whether there
will be adequate clearance for your application.
APPENDIX
CABLE: MODEL 5028-187 (SCSI-2 to Flat Ribbon, Shielded)
Type: Round shielded cable, 50-wires (SCSI-2 male connector at
one end and a flat female ribbon connector at the other end).
The cable length is 2 meters (6.56 feet). This shielded cable is
recommended for all I/O applications (both digital I/O and
precision analog I/O).
Application: Used to connect Model 5025-552 termination panel to
the PMC230 Module.
Length: Standard lenght is 2 meters (6.56 feet). Consult factory for
other lenghts. It is recommended that this length be kept to a
minimum to reduce noise and power loss.
Cable: 50 conductors, 28 AWG on 0.050 inch centers (permits
mass termination for IDC connectors), foil/braided shield inside
a PVC jacket.
Connectors: (One End): SCSI-2, 50-pin male connector with
backshell and spring latch hardware.
(Other End): IDC, 50-pin female connector with strain
relief.
Keying: The SCSI-2 connector has a “D Shell” and the IDC
connector has a polarizing key to prevent improper installation.
Schematic and Physical Attributes: See Drawing 4501-758.
Electrical Specifications: 30 VAC per UL and CSA (SCSI-2
connector spec.’s). 1 Amp maximum at 50% energized
(SCSI-2 connector spec.’s).
Operating Temperature: -20
°
C to +80
°
C.
Storage Temperature: -40
°
C to +85
°
C.
Shipping Weight: 1.0 pound (0.5Kg), packed.
TERMINATION PANEL: MODEL 5025-552
Type: Termination Panel For PMC Module Boards
Application: To connect field I/O signals to the PMC Module.
Termination Panel:
Acromag Part 4001-040 (Phoenix Contact
Type FLKM 50). The 5025-552 termination panel facilitates the
connection of up to 50 field I/O signals and connects to the
PMC Module via a flat ribbon cable (Model 5025-551-x). Field
signals are accessed via screw terminal strips. The terminal
strip markings on the termination panel (1-50) correspond to
field I/O (pins 1-50) on the PMC module. Each PMC module
has its own unique pin assignments. Refer to the PMC module
manual for correct wiring connections to the termination panel.
Schematic and Physical Attributes: See Drawing 4501-464.
Field Wiring: 50-position terminal blocks with screw clamps. Wire
range 12 to 26 AWG.
Mounting: Termination panel is snapped on the DIN mounting rail.
Printed Circuit Board: Military grade FR-4 epoxy glass circuit board,
0.063 inches thick.
Operating Temperature: -40
°
C to +100
°
C.
Storage Temperature: -40
°
C to +100
°
C.
Shipping Weight : 1.25 pounds (0.6kg) packaged.
