User Data Size The hexadecimal number of bytes of a data block to use for a device
operation. Normally, this value is equal to the device size. During serial
set operations, this value works with Total Set Size to determine the total
amount of bytes to program into a set of devices.
User memory The workspace used during device operations. It can be either internal
RAM or a disk file. Normally, RAM is used for small, quick device
operations, such as programming a single device, while disk is used for
larger device operations, such as serial set programming.
User Menu Data The information you see when you look at the programmer screen. It
includes such items as the dialog window, reminder bar, and message
bar.
User Menu Port The port the user menu data is sent to. You can re-direct user menu data
to either the Terminal port of the Remote port.
User RAM The RAM in the programmer. User RAM can be used as a source/
destination for an operation. Several operations use User RAM as a a
temporary storage buffer, overwriting any data that may have been there
previously.
Verify Device A device operation that compares data in a programmed device with data
in RAM or in a disk file. With logic devices, verifying can also include
functional testing. Verify is an automatic part of the program operation,
but additional verify operations can provide useful information about
any errors.
Verify Pass A verify pass is a trip through a device at a specified Vcc to see if the
device programmed properly. The pass is usually done once at 5V. The
pass can also be done twice, with the first pass at 5.5V and the second
pass at 4.5V.
Waveforms Images of the programming pulses that program a device. Usually
created by programmer manufacturers and submitted to device
manufacturers as part of the approval process and to record the correct
programming spec for a specific device.
Wildcard Used when entering filenames, a wild card represents one or more
characters in a filename. For example, 27*.dat represents both 27512.dat
and 27128.dat.
Workstation A PC or other micro computer used for local control of the programmer.
You must use terminal emulation software, such Data I/O’s HiTerm, to
allow the programmer and the PC (or other micro) to communicate. The
programmer is designed to be compatible with all popular design
workstations, including both DOS and UNIX-based workstations.
Yield The percentage of successfully programmed devices.
