Operating System Downloads
Note: See Table 18 to compare the general features of operating
system downloads to different types of application system
downloads.
An operating system download has the following effects on the
receiving terminal:
• It overwrites the existing TXO operating system version,
including the bootloader software that is stored in the flash
EPROM. (There is no partial operating system download.)
• It erases the application program and all records, protected and
non-protected, that are stored in the application memory
• It erases any unprocessed transactions.
For these reasons, be sure that all transactions on the receiving
terminal have been completed before you initiate an operating system
download. In addition, be prepared to download a new application
program to the receiving terminal when you are finished with the
operating system download.
Hardware and Software Requirements
The hardware requirements for operating system downloads are
identical to those of corresponding application download methods:
• For direct downloads, a cable connection is required between the
download computer and the receiving terminal.
• For downloads by telephone, the download computer and the
receiving terminal must have a dial-up modem connection.
• For terminal-to-terminal uploads, a cable connection is required
between the sending and receiving terminal. In addition, the
SRAM size of the receiving terminal must be the same as, or
larger than, the SRAM size of the sending terminal.
