3. Product Description
PL18EV is an 18-channel transmitter dedicated to engineering vehicles, equipped with 2.4GHz AFHDS
3 (third-generation automatic frequency hopping digital system). The standard configuration is an FGr12B
receiver!
3.1 System Features
AFHDS3
(third-generation automatic frequency hopping digital system)
is a newly developed digital wireless
system. It is compatible with single antenna bidirectional real-time data packet transmission and data stream
transmission. With the advantages that come with the WS2A wireless system and the new 2.4GHz chip, the system
can dynamically set: number of channels, channel resolution, range, anti-interference requirements and latency to
meet the needs of different users.
Single Antenna
Bidirectional
Real-time Data
Transmission
The receiver can receive data from the transmitter and the transmitter can receive data from the
receiver, this includes data from sensors, such as temperature and speed and support the i-BUS.
This gives more control over the aircraft and constant information on its current status.
Uncorrected Data
Transmission
The independent uncorrected data transmission module is built into RF system; it can send
many different types of data including flight control data.
Intelligent RF
configuration
Depending on hardware, certification, the amount of data to be transmitted, anti-interference,
latency and distance requirements, the system intelligently adapts the corresponding RF
configuration to meet the requirements of the user.
Multi-channel
Frequency
Hopping
This systems bandwidth ranges from 2.402GHz to 2.480GHz. This band is divided in 140
channels. Each transmitter hops between 16 channels (32 for Japanese and Korean versions) in
order to reduce interference from other transmitters.
Unique ID
Recognition
System
Each transmitter and receiver has it's own unique ID. Once the transmitter and receiver have
been paired, they will only communicate with each other, preventing other systems accidentally
connecting to or interfering with the systems operation.
Low Power
Consumption
The system is built using highly sensitive low power consumption components, maintaining
high receiver sensitivity, while consuming as little as one tenth the power of a standard FM
system, dramatically extending battery life.
