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).
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 transparent
transmission of data streams . 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 system supports one-way and two-way connections. When the transmitter is working
in one-way transmission way, the receiver can receive data from the transmitter. When
thetransmitter is working in two-way transmission way. The receiver can receive data from
the transmitter and the transmitter can also receive data from the receiver, as well as the
information cross from the temperature and speed sensor modules.
Transparent
Transmission of
Data Streams
The independent data transparent transmission module is built into RF system, which
canrealize data transmission via transmitter and transparent transmission. It can be used for
datatransmission of flight control.
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 bound, they will save the each other's ID and only connect with each other. When
the syetem is working,if the IDs are matched with each other, then the connection will be
connect, otherwise, there is no connection between transmitter and receiver. This unique
ID recognition syetem resists the interference so as to make the system stabler and more
reliable.
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.
