Telos ZephyrExpress user manual Software Updates, Introduction

Introduction

This section covers system-level functions that have aren’t part of normal audio or ISDN operations: updating the software, and using the serial and parallel ports.

One other system function — setting the internal clock — is so simple that it’s covered in a few paragraphs as System menu: Set time in section 6.

Actually, all of the system functions in ZephyrExpress are designed to be transparent to the user. Unless you want to learn all its inner details and capabilities and intend to make your ZephyrExpress sit up and do tricks, you can probably skip this section.

Software Updates

This manual is being written for the first public software release, and there haven’t been

hany updates yet. The procedure for distributing new software — whether it’ll be sent on eproms, floppy disk or distributed over the Internet for download from a computer, or even transmitted directly to ZephyrExpress via an ISDN call — is still undetermined.HOT TIP!New software and upgrade procedures will always be announced at our web

site, www.zephyr.com.

The System: Software menu item includes four choices for using new software once it’s been downloaded into the unit:

•Try new Reboots ZephyrExpress and runs the new software for this startup only. The older software remains the default, and will be active the next time you start up. But the new software also stays in memory, and you can Try new again.

•Revert Reboots ZephyrExpress with the default software. This is the older version until you specifically replace it by using the Set default command. The newer version remains in memory, and you can Try new again.

• Set default Reboots the unit using the currently-running software and make it the default. If you are currently running the new software under of a Try new command, it will become the default and the older software will be erased. However, if you run Set default immediately after downloading new software, the newer software isn’t running yet and won’t be made the default.

•No change Escapes from the menu item, doing nothing.

TO INSTALL NEW SOFTWARE AS THE DEFAULT:

1.Download the software into ZephyrExpress

2.Select System Software: Try new. This restarts ZephyrExpress with the new software. Try it and make sure you’re happy with the newer version.
