Each individual SensorNet or AD RS-422/485 connection can be set to the "Variable" speed (default) or
the "Legacy" mode that applies to all domes on the respective connection (see the following table).
Manchester only uses variable speed commands and has no return data so this section does not apply.

"Variable" speed (default)
When doing pattern programming, the variable speed pan and tilt commands will be used to allow the
variable speed pattern feature of the SpeedDome Ultra VIIe and 8 to be used.
• SpeedDome Ultra VII with V1.05 firmware or later, SpeedDome Ultra VI upgraded to VII with chip
change, and all SpeedDome Optimas will use these variable speed commands and produce accurate
fixed speed commands.
• Older SensorNet and AD RS422/485 domes will use these variable speed commands, but patterns
may not always be accurate.
This mode will use the variable speed commands for AD RS422/485 if return data is not available,
therefore Mini, UTPZ and older domes will loose pan and tilt functions when return data is not present.
"Legacy" mode
• Fixed speed commands are used for pattern programming. Therefore, legacy domes have accurate
patterns.
• If return data is not available, this mode uses fixed speed commands for AD RS422/485; therefore,
Mini, UTPZ and older domes do not loose pan and tilt functions when return data is not present.
• AD RS-422/RS-485 SpeedDome Optima LT only operates with fixed speeds.
