ProMaster 2500 User Manual 3-7

Selecting the Data

Source

Select the

Data Source

field to choose where the 2500 will retrieve the

data to be programmed in the device.

When you select

PC Disk File

, two additional fields allow you to select a

data translation format and a data file name. These additional entry fields

are:

• Data File

• Translation Format

If you select

Master Device

as the data source, TaskLink will prompt the

operator to insert a master device into the input track section. The beam

places this device in the programming module and its data is read into

RAM. The master device is then placed into the device recess next to the

labeler.

If you select

Programmer Disk File

, TaskLink looks for the data file on

either the 2500’s floppy disk drive (A:) or one of the Mass Storage Module

drives (C: or D:). Files from these programmer disks are unformatted data

files. If you do not specify a drive before the file name, TaskLink looks for

the file on drive A.

Programmer disk file commands are not displayed on the TaskLink

menus by default. To see these commands on the TaskLink menus, you

must select the

Enable Programmer Disk Options

from the

Set

Preferences

dialog box (see Figure 3-21).

Data File Entry Field

The most common method of retrieving programming data is to

download it from a PC file to the 2500’s RAM. Press

to move the

cursor to the

Data File

field and enter the name of the data file. Include

the PC drive letter and path if the file is not located in the same directory

as TaskLink. The entry line “

drive:\path\file_name

” might look

something like “

c:\pld_data\U49.jed.

”

TaskLink displays a list of data files on the screen. To see the list, move

the cursor to the

Data File field and press

. Use

and the arrow keys

to move the cursor to a file on the list. Press

↵

and the file is selected for

this Task. TaskLink returns to the

Edit Task

dialog box and displays the

path and filename. (The Host Command and the Terminal/Host options

are not currently used on the 2500.)

Translation Format Entry

Field

After data is created, it is stored in a particular data translation format.

When downloading from a host or PC disk file, you must set up TaskLink

to use the same translation format.

Select a new translation format by moving the cursor to the

Translation

Format

entry field. Press

to access the Translation Format list box, and

use the arrow keys or the mouse and scroll bar to scroll through the list

and highlight the translation format you want. Press

↵

to select that

format. TaskLink returns to the

Edit Task

dialog box and displays the

new translation format.

Note: When you choose a format, consider its compatibility with high speed

download.

Tasks and Kits

3-8 ProMaster 2500 User Manual

For logic devices, the primary choices are two JEDEC formats (full and

kernel) and Altera POF.

Selecting a Process

The

Process(es)

check box area of the Edit Task dialog box lists the

operations that can be performed on a device. The three columns of check

boxes allow you to configure three different combinations of operations,

or process(es), within the Task.

When at least one operation is selected in more than one column, the

operator running this Task will be presented with a selection box and

asked to choose one of the Processes on the screen.

Highlight the desired operation(s) in each column. Press

PACE

to enable

(check) or disable (uncheck) the operations.

The parameter choices are listed below:

•

Blank Check

—This test runs before the device is programmed to see

if the device has any programmed bits (fuses). If programmed bits are

found, the device is rejected and placed in the fail tube. When this test

is not selected as part of the Task process, the 2500 programs and

verifies the device without checking for programmed bits.

•

Illegal Bit

— This test is performed before the device is programmed

to determine whether the device has any illegal bits. An illegal bit is a

bit (fuse) in the device that is programmed when the RAM data for

the same bit specifies that it should be unprogrammed (see Figure

3-5). For all devices except electrically erasable parts, this is an illegal

operation and the device will be routed to the

Fail

output tube. This

test is not performed on an electrically erasable device, because those

devices are completely erased before they are programmed so no

illegal bits can occur.

•

Program

—Select this parameter to program the device as part of the

Task operation. When this is selected, the

Verify

parameter is also

selected. TaskLink does not allow

Program

to be selected without

including the Verify operation.

•

Verify

—Select this parameter to have the 2500 compare the data

programmed in a device to data in RAM. Verify is automatically

selected by TaskLink when Program is selected. Verify may be

selected without selecting Program when you need to check devices

that were programmed earlier.

•

Label

—Select this parameter to label the devices. Devices do not

have to be programmed (or verified) and labeled in the same process.

They can be programmed and placed in tubes to be labeled by the

2500 later. The 2500 default configuration will not label devices that

have failed the programming operation. (The 2500 can be configured

to label both passed and failed devices. Refer to the

Binning

command in local mode in Appendix F.) Devices that have failed can

be labeled only by passing them through the 2500 a second time.

Selecting Handling/

Labeling Parameters

Numerous parameters are available by selecting the

< More >

pushbutton. Press

↵

and the

More Task Parameters

selection box

appears (see Figure 3-1, screen 4). Most of these should remain at their

default settings.

The parameters that must be defined for all Tasks are the

Handling/

Labeling Parameters...

selections. Move the screen cursor over

Handling/Labeling Parameters...

and press

↵

to select this parameter

set. The following handler and labeler parameters are defined in this

dialog box.

Selecting the Package Type

The

Package

field defines the device package type you will be

processing. Move the screen cursor to this field and press

. TaskLink

displays a list of package and pin counts from 8-pin DIP to 84-pin PLCC

devices. The package type “

DIP 24-.3

” represents a 24-pin DIP device in a

300 mil. package width.

To select a new package type, move the screen cursor to the new type and

press

↵

Device Orientation: Pin 1

Press

to move to the

Pin 1 Orientation

field. This parameter is

critical because it tells the 2500 where pin 1 on the device will be

positioned in the input track. The beam inserts the device into the

programming module with pin 1 always to the right, pointing toward the

input tube. The Task must accurately identify the position of pin 1 as the

devices are loaded in the input track so that the beam rotates and inserts

it in the programming module correctly.
