6.3.6 RESTORING THE DATABASE FROM A COMPUTER
A binary format database file that has been saved to disk may be loaded into the RDU as
follows.
1. Connect the computer to the controller as described in section 6.3.9.
2. Enter program mode as described in section 6.3.2, then from the main program mode
menu press the right arrow key and select option 3:Database load. The message
“Press ACK, then start sending the new database” should appear.
3. Press the "ACK" key on the controller keypad, then initiate the transmission of the
database file from the computer. With a terminal emulator, this usually involves using an
upload/download command or send command in the terminal emulator. The controller
display will show an incrementing count as the database is received, plus the message
“Loading. Press RESET to abort”. When the database has been completely received,
the controller will verify its checksum and display the success or failure of the operation.
If the load is successful, the database is written to flash memory automatically. When
program mode is subsequently exited, if no further changes have been made, the display
should indicate that the database has not been changed. In this case, it isn't necessary
to save the database when exiting program mode because it was saved automatically
after the database load.
The controller must receive a complete database with the correct number of records or it will
display an error message.
The controller will transmit XON, XOFF characters for handshaking if it needs to slow down
the rate of data being sent to it. If XON/XOFF handshaking is not available on the computer,
or if errors occur, then a slower rate (e.g., 2400) should be used. The baud rate used by the
controller is programmable (see section 6.4.4.7) but if the database that has been loaded
contains a baud rate setting different to the prior database, the actual baud rate used by the
controller hardware will not be changed until the CLEAR key is pressed to initiate an exit
from program mode.
Database Conversion
If the loaded database was created with a version of software earlier to V5.00, then an error
will occur and the database cannot be used. An older database must first be converted to
V5.xx using a PC utility and then loaded into the RDU.
6.3.7 VERIFYING A SAVED DATABASE
A binary format database file that has been saved to disk can be verified at any time without
entering program mode as follows.
1. Connect the computer to the controller as described in section 6.3.9.
2. Press the SET key from the base display, then press the right arrow key to select the
second menu 1:Verify database 2:PSU fault inhibit
Select option 1 verify database. Enter an access code when prompted. The following
message should appear. Press ACK, then send the database to be verified.
3. Press the "ACK" key on the controller keypad, then initiate the transmission of the
database file from the computer. With a terminal emulator, this usually involves using an
upload/download command or send command in the terminal emulator. The controller
display will show an incrementing count as the database is received, and the following
message will appear. Verifying. Press RESET to abort
The success or failure of the verify will be indicated on the controller display. The RESET
key can be pressed to terminate the verify operation at any time.
