Automatic Frequency Selection
When using
Auto
mode, the system automatically selects the most suitable channel to work on from all available frequencies.
•
The number of available frequencies varies according to regulations and sub region settings.
•
The system constantly monitors in-channel interferences, and if detected, it will instruct both the transmitter and the receiver to
seamlessly transfer to an alternative vacant frequency.
•
Channel hopping is instantaneous, in between video frames, and has no visual effect or video degradation.
Manual Frequency Selection
The
Fixed Frequency
mode provides an organized group or race manager with greater control and management possibilities. In this mode, the user
explicitly selects the frequency of the channel to be used by each ProSight System.
•
Fixed mode enables mixed heats involving both analog SD and digital HD drones.
•
In this mode, the system will NOT change its frequency, even if it detects interference from other systems.
•
In order to have multiple simultaneous channels, the center frequencies of the systems must be at least 20 MHz in the ProSight camera,
and 30 MHz in the ProSight HX camera apart. The available channels are listed in a set of actual frequency number and predefined
channel sets, named “ProSight Channel Sets”.
ProSight Channel Set
is a list of available operating channels. Regulations require that each of these channels includes a specific and an alternate
frequency. The ProSight Channel Set was designed to comply with DFS regulations.
DFS
“Dynamic Frequency Selection” requirement is enforced to ensure that channel sensing and avoidance capabilities are used to detect radar
activity (usually meteorology radars).
By complying with the DFS requirement, the CONNEX ProSight System can use a larger set of frequencies, which would otherwise be restricted.
Tips:
• Analog systems are restricted from using the DFS bands
• In order to comply with EU regulation, EU systems will change their frequency, even in Manual mode, when
interference is detected.
