Commands
� I/O Addr Offset
Specifies the beginning address of the downloaded data file to be
compared. This field appears only when a non-JEDEC format has been
selected. Entering FFFFFFFF causes the programmer to default to the first
incoming address as the lowest address to be compared.
� Memory Begin Address
Specifies the first hexadecimal address of data to compare with data from
the Source port. If the data location is RAM, it is a beginning RAM address.
If the data location is Disk, it is a beginning disk file address. This field
appears only when a non-JEDEC format has been selected. The default
address is 0.
� User Data Size
Specifies the hexadecimal size, in bytes, of the data block to be
downloaded and compared from the Source to the data location. This field
appears only when a non-JEDEC format has been selected. Normally, you
should enter a zero here so all the data is compared. After the compare
operation is complete, a value equal to the number of bytes compared is
set here. If a value less than the size of the data received is entered, only
the number of bytes equal to that value are actually compared.
� Download Host Command
Enter the appropriate host command line here to download the data. This
line may be up to 58 characters long. The programmer generates a return
character to terminate the line when transmitted to the host. To clear a
previously entered command, press SPACE then ENTER.
More Commands / Transfer Data / Format Select
The Format Select command selects the translation format to use. Translation
formats (a form of transmission protocol) are used when data is uploaded or
downloaded between the programmer and a host computer. Chapter 5 lists
and describes the formats supported by the programmer. If your host
computer does not generate code into one of the listed formats, edit it to
match one of the supported formats.
The Format Select screen lists the programmer supported formats to choose
from. Enter the number of the format that you want to use in the format entry
field at the bottom of the screen, then press ENTER. When you select a
translation format from this screen, the same format is entered in all the other
Transfer Data screens (such as, Download Data and Compare Data).
More Commands / Transfer Data / Input From Disk
Use this command to load a data file from disk if the data is stored in a
translation format. Depending on the settings of the Destination parameter,
the data in the disk file is loaded into either RAM or another disk file.
To input a data file from disk, follow these steps:
1. Insert the disk containing the file to input into the drive.
2. Specify the settings for the parameters listed below.
3. Press ENTER to start this command. The programmer displays Data
transfer complete when the file has been loaded.
