within 60 msecs of receipt of the Quick recall command.
2. The switcher ignores any invalid command or non-switching commands received between
the Start and End commands.
3. If there is no activity for 5 seconds, the switcher returns the timeout (E17) error.
4. The switcher disables front panel switching during this sequence of commands.
5. The switcher returns the invalid command (E10) error if it receives the End command
without the start command or the Quick recall command without a prior direct preset write.
6. The switcher must receive the Quick recall command within 100 msecs of the End
command.
