3980xpi Users Manual - Data I/O Corporation

Commands
Specifying FFFFFFFF instructs the programmer to set the I/O Addr Offset to
the first incoming address of data received from Input from Disk and
Download operations. During Output to Disk and Upload operations, setting
the I/O Addr Offset to FFFFFFFF is the same as setting the I/O Addr Offset
to 0, since no offset is added to the I/O addresses sent out. This parameter
defaults to FFFFFFFF.
To load your file absolutely, set the I/O Addr Offset to 0; the data is stored
at the addresses specified in the data file.
� I/O Timeout
Limits the time (0 to 99 seconds) the programmer waits for data transfer
to begin. 0 disables the timeout. Use the 0 setting only for data formats
that use a start code and end code. These formats, which include codes 5,
6, 7, 9, 11, 13, 16, and 96) need the timeout enabled in order to terminate
a normal data transfer.
� Upload Wait
Sets the period that the programmer waits before it begins sending data to
the host computer after the host upload command is sent. The range of
this parameter is 0 to 99 seconds.
� Transmit Pacing
Specifies the time-delay to insert between characters transmitted to a host
during an upload. See the note about transmit pacing at the end of this
section for more information.
� Download Echoing (Y,N)
Displays the data being downloaded, which may slow down the process of
receiving data and is not recommended for high baud rates, such as 9600
and above. Download echoing may not be used with the binary formats.
� Output Record Size
Specifies the number of data bytes contained in each data record during
upload. The range of this parameter is 0 to 256 bytes. Some formats have
fixed record lengths for which this parameter does not apply.
� Number Of Nulls
Sets the number of null characters sent between each record in a data file
after a carriage return and line feed. The range of this parameter is 0 to
254 nulls. Entering 255 specifies no nulls and suppresses the line feed.
� Instrument Control Code
Specifies how the data transfer will be controlled. Selecting 0 specifies
regular XON/XOFF handshaking; selecting 1 or 2 specifies a special
handshaking sequence (see Chapter 5 for more information).
� Fill Memory Option (N,D,U)
Specifies what data user memory will be filled with before download
begins. It is used for Download Data and Input from Disk operations. The
choices are N (none), D (default), and U (user specified). If you select N,
user memory will not be changed and whatever is in user memory will be
overwritten by the downloaded data. If you select D, user memory will be
filled with the data appropriate to initialize unused locations to the
unprogrammed state for the device type selected. If you select U, user
memory will be filled with what you specify in the Fill Data option.
