The default data bit, stop bit and parity values of the drive are “8”, “1”
and “NO”, respectively. These settings can not be changed. The Y
Modem Batch file transfer is the only protocol available for
communicating with the DSD 406/412.
In uploading and downloading
files, the drive behaves like a
bulletin board service to the PC.
A file upload means that a file
is sent from the PC to the drive.
A file download means that a
file is sent from the drive to the
PC.
There are two file types associated with upload and download. The
PAC program file (i.e. the .PRG file) contains the executable
instructions that determine the application characteristics of the drive.
The parameter file is the file of all the parameter settings of a drive at
the time the .PAR file was captured.
●
Program upload
is the process of a computer sending a new
PAC program (i.e. the .PRG file) to a DSD 406/412 through the
drive’s serial port. This process may be required when, upon
application of power, the drive finds the PAC program loaded
into memory is invalid. This process may also be used when it is
desired to change the PAC program from what was previously
loaded. Some of the steps shown below are skipped when the
PAC program in memory is found to be invalid.
●
Program download
is the process of the DSD 406/412 drive
sending the PAC program (i.e. the .PRG file) through the drive’s
serial port to a computer. This process can be used for memory
backup.
●
Parameter upload
is the process of a computer sending all
settable parameters (i.e. the .PAR file) to a DSD 406/412 drive.
This process can be used to set up the drive with a set of tuned
constants.

CAUTION
The communications software must be set up to match
the baud rate of the drive.
