Fuse Verification
A type of post-programming device check that checks the fuse pattern
programmed into a logic device against the pattern in user memory.
Fusemap
The fuse-level description portion of a programmable integrated circuit.
Fusemaps are typically files in JEDEC Standard #3A format and are
downloaded to PLD programmers for programming or verifying a
device.
High-speed Logic Drivers
A logic device test that increases the speed of the logic transitions
between 0 to 1 and 1 to 0 of the test vector input states. This test is a
diagnostic tool designed to help debug and classify test vector failures.
Specifically, this test is designed to help identify vector transitions that
are speed dependent.
I/O Address Offset
This value influences the beginning address where data is stored during a
file transfer operation. For uploads from the 2500, the I/O Offset is an
address value add to the RAM address for each transferred data byte. For
downloads, the I/O Offset is subtracted from the beginning address in
the formatted data file. The result is then added to the memory begin
address to determine where the block of data is loaded.
I/O Timeout
The amount of time that the programming electronics will wait for a data
transfer to begin.
I/O Translation Format
See Data Translation Format.
Illegal Bit
An illegal bit is a programmed location in a device that the data file
specifies should not be programmed.
Illegal Bit Check
A test that determines whether or not a socketed device contains any
illegal bits.
JEDEC
An acronym for Joint Electron Design Engineering Committee, which is a
committee of programmer and semiconductor manufacturers that
provide common standards for programmable issues. Examples include:
acceptable test characters for PLDs and standard data transfer/
programming formats for PLDs. JEDEC Standard #3A is the industry
standard for PLD formats.
JEDEC Standard #3A
The standard PLD data translation format (as defined by the JEDEC) for
PLD design software to communicate with PLD programmers. It defines
the states of all fuses in the device (the fusemap) and may include test
vectors for device testing.
LED
An acronym for Light Emitting Diode. The 2500 has one external LED on
the disk drive and numerous internal LEDs on the handler controller
board used for diagnostic tests.
Liner
The non-adhesive backing that holds the blank labels on a label roll.
Labels are removed from the liner by the 2500 and applied to the device.
Load Device
A device operation that copies data from a master device into user
memory.
Local Mode
One of two system operation modes for the ProMaster 2500. When placed
in local mode, the 2500 responds to commands sent either from the front
panel or its internal firmware. In this mode, the 2500 is not operating with
TaskLink. The other general operating mode for the 2500 is Remote
mode.

Logic Verification
After programming a device, you can select test vector verification, fuse
verification, or both types of verification.
Main Plate
The metal plate on which the tracks, beam, tube holders, and beam
carriage assemblies are mounted. The hood rests on the main plate when
it is closed.
Mass Storage Module
(MSM)
The hard disk drive contained in the programmer that stores the system
startup and TaskLink software, programming algorithms, and device
programming database files.
Master Device
A device that contains data you want to program into another device. For
example, you might load data from a master device and then program
that data into a blank device.
Memory Begin Address
The first address, in hex, of the first byte of data to be used in device
operations. If the data source/destination is RAM, the memory begin
address is a RAM address. If the data source/destination is disk, the
memory begin address is the offset for a disk file.
Operator Mode
One of two TaskLink modes of operation. (The other mode is called
Administrator mode.) Operator mode is intended for use by the
ProMaster 2500 system operator to run Tasks and Kits. A limited number
of commands are presented in the interest of making the system easier to
operate with the goal of maximizing device throughput. The Operator
mode does not allow you to edit Tasks and Kits. The Administrator mode
allows you to edit Tasks and Kits.
Optics
A pair of components used to detect an opaque object blocking its light
beam. The pair is composed of an infrared light-emitting element (called
the emitter) which is in-line with a light detecting element (the collector).
All emitters on the 2500 are of the same type and can be identified by
their red and black wires. There are two types of collectors. The standard
collectors are used in most optic locations and can be identified by their
blue and yellow wires. One exception is the ADC’s super optic collector.
It has a higher light sensitivity and cannot be exchanged with other
collectors in the 2500.
PAL
An acronym for Programmable Array Logic. A PAL is a device with
programmable AND and fixed OR arrays. This is a slightly different
architecture from a PROM or an FPLA. Other examples of PAL-type
architectures from other manufacturers include PEEL and GAL.
Parameter Entry Field
See Field.
Part Number
The number on the device. For example if you are using an Intel 27C256,
then the part number of the device is 27C256.
PIC
See Programmable Integrated Circuit.
Pin-driver Board
The electric circuit reading or applying voltage and current pulses to the
individual pin of a device, for programming or testing.
PLCC
An acronym for Plastic Leaded Chip Carrier. A device package with
J-shaped leads extending from four sides downward, used for surface
mount applications.

PLD
An acronym for Programmable Logic Device. A particular type of
programmable integrated circuit. Architectures range from being very
simple to very complex. Most PLDs contain two levels of logic: an AND
array followed by an OR array.
PROM
An acronym for programmable read-only memory. A device with fixed
AND and programmable OR arrays. This is a slightly different
architecture from an FPLA or a PAL.
Process
A series of device related operations are combined to form a process for
each Task. The device related operations that can be selected are: Blank
Check, Illegal Bit Check, Program, Verify, and Label.
Programmable Integrated
Circuit (PIC)
One of the four basic categories of ASICs — the other three being gate
arrays, standard cells, and full custom devices. PICs are user
configurable. PLDs and FPGAs are examples of programmable integrated
circuits.
Programming Block
The socket on the programming module where the 2500 inserts devices
for programming. The module’s contacts are mounted in the
programming block.
Programming Electronics
(PE)
The electronic assembly in the 2500 base that controls the electrical
signals required to perform device test, program, and verify operations.
Often referred to as “PE” in the documentation.
Programming Module
The interface between the 2500 programming electronics and the device.
The programming module routes signals from the pin driver head to the
device pins.
Programming Station
The cut-out portion of the main plate where the programming module is
installed.
Remote Mode
One of two system operation modes for the ProMaster 2500. In this mode,
the 2500 is configured to respond to commands sent by TaskLink. This is
the primary operating mode for the ProMaster 2500. The other system
operating mode is called Local mode.
Security Fuse
A location in a programmable device that, when programmed, secures
the device from readback: the data in the device becomes unreadable.
Security Fuse Data
The data programmed or that will be programmed into the device’s
security fuse.
Security Option
A programming parameter defined in the Task the enables or disables the
programming of the device’s security fuse.
Select Device
A procedure that tells the 2500 programming electronics what device you
will be using. You select a device by choosing the manufacturer and
device part number off a list on TaskLink’s screen.
Self-test
A command that tests various circuits and subsystems in the 2500
programming electronics, verifying proper operation or isolating possible
problem areas.
