Alto 818 Installation and Operation
6-38 P/N 66109074001 Rev. D
6.3.28 XSAVE
The XSAVE command is used to save the system setup data to a hard drive or diskette. The file
transfer is via an Xmodem program executed with an IBM PC or equivalent. There are several
Xmodem file transfer programs that can be used for this purpose. Crosstalk and TERMINAL.EXE
are two examples.
In case of a power failure to the ACU, the Alto 818's internal battery will provide power to the
system memory for as long as one year. However, should any emergency event occur that
causes the database to be tampered with or deleted from memory, a backup to a hard disk or
a diskette containing the system database setup will prove invaluable. Also, in the event that the
ACU requires replacement, the time-consuming process of setting up the database for the new
unit can be eliminated if the database from the old unit has been saved.
To download the ACU database to the PC using TERMINAL.EXE, proceed as follows:
1. Connect the ACU host port to the desired communication port of the PC using a null modem
cable.
2. Start the terminal program on the PC setting the parameters as follows:
Baud set to same rate as the ACU
Data Bits 7
Parity ODD
Com Port set as required
3. On the PC, press Alt-M to access the menu. Select RECEIVE A FILE and press ENTER.
4. Select XMODEM CHECKSUM and press ENTER.
5. Type the name of the destination directory and file, including extension, and press ENTER.
The PC will begin to receive data from the ACU. Reset the ACU when the data transfer is
complete.
