Follow the steps below if you need to change a parameter:
1.Move the cursor to the field you need to change.
2.Type the new value and move the cursor to another field. If the parameter is
acceptable, the programmer displays Parameter Entered in the message
bar, which is located below the status window.
If you enter an incorrect parameter, the programmer beeps and displays an
error message. Continue until the displayed parameters match your
configuration.
1.Press ESC CTRL+T to enter Transparent mode.
2.Change to the directory containing the file you will download (for a UNIXbased
host, use the CD command).
Note: The commands in this Session are for UNIX-based hosts.
Substitute the appropriate commands if you are using a different
host, such as a VMS-based machine. If you need more information,
consult the system's documentation or your system administrator.
3.Press ESC CTRL+T to leave Transparent mode and return to the programmer
interface. (You may have to press CTRL+R to redraw the screen.)
4.If the sample data file is in your current directory, type the following
Download Host Command: cat sample.dat (substitute the appropriate
filename if you are using a different file), then press ENTER. The message bar
displays Parameter Entered.
The Download Host Command is a command that the programmer sends to
the host to initiate the download. Because you are on a UNIX-based host,
you use the CAT command as the Download Host Command.
5.Press ENTER to begin the download. The action symbol rotates while the data
is being downloaded. When the download is finished, the message bar
displays Data transfer complete. Data sum = xxxxxxxx, where
xxxxxxxx indicates the sumcheck of the data transferred.
The sumcheck for memory devices is an eight-digit hexadecimal
summation of the downloaded data. If you change one byte of information
in the data file, the sumcheck will also change. The sumcheck is a good
method of verifying that the data you downloaded matches the data on
your host.
Later, when you program this data into a device, the programmer will
generate another sumcheck. If the two match, the data programmed is the
same as the data downloaded. If the two sumchecks are different, the data
programmed is not the same as the data downloaded.
In this Session, you learned how to download data to the programmer from a
host connected to the Remote port on the programmer. The steps were
1.Select the translation format that matched the format of your data file.
2.From the Main Menu, press M T D to go to the download screen.
3.Set the parameters on the Download screen to match your setup.
4.Enter the host Download Host Command. For example, to transfer the file
filename.dat you would enter cat filename.dat for a UNIX-based host. If
you are using a VMS-based host, you would enter type filename.dat.
