Device>Read

Selecting Device>Read retrieves the data contents of the device in the socket and

reads them into memory. While the read operation is in progress, the status window

displays the term ACTIVE and shows the percentage of completion. When the read

operation is complete, a PASS or FAIL message indicates its success or failure. Using

the <Read Device> button in the Device Action section yields the same results. Any

additional information related to this read operation is also displayed in the Messages

section of the screen:

Successful completion of a READ operation

When using a Multisyte programmer, insert the device in the left-most TOP for the

read operation.

Device>Blank Check

The Blank Check feature may be enabled or disabled depending on the device

selected. If the feature is enabled, selecting Device>Blank Check lets you determine

if the device under test is truly empty. If the blank check passes, the device is truly

empty. Otherwise, some of the device locations may have data in them.

UV erasable devices must be erased under ultraviolet light in accordance with the

manufacturer’s instructions before programming.

Note: Not all UV erasable devices are guaranteed to arrive blank

from the manufacturer. If they are not blank, simply erase

them according to the manufacturer’s guidelines for the

device under test.

The Blank Check function is performed prior to all programming functions. You may

also initiate the Blank Check operation from the <Blank Check> button in the Device

Action section of the screen.

Device>Verify

Devices may also be verified with known good data by selecting Device>Verify To

use this function, you must first read the device’s data into the programmer/software

RAM. The data can be read two different ways:

x Select Device>Read to read a master device into programmer/software RAM.

x Select File>Load to load a data file into programmer/software RAM.

Once the data to be verified has been successfully loaded into programmer/software

RAM, insert the device into the programmer socket. Select Device>Verify, or click

the <Verify> button in the Device Action section of the screen to initiate the Verify

action. During the Verify action, a byte-by-byte comparison is performed between the

data in RAM and the device in the socket. When the Verify action is complete,

PASS/FAIL results will be displayed in the Status section of the screen, as well as in

the Messages section
