7. The installing schematic
8. Notices during the use of KYL-600L
1) The antenna should away from the power supply if use the switch power, because
the transmitting of the antenna may affect the normal work of the switch power. When
the transmission happen fault, checking the power voltage whether interfered from the
antenna is one way of eliminating fault.
2) Use the min. grain wave and high anti-jamming switch power or batteries
3) The power capacity must meet D.C. 5~12V, more than 800mAoutput current
4) The space between the experiment Radio should be more than 5m. The antenna
should span on the high to increase the distance of electric wave. It is important for
using shortwave communication equipment in the city.
5) After connecting the antenna to the Radio, the space between the Radios should
more than 10m, so avoiding signal backup.
6) The antenna plywood should nip in the connection inside the antenna, but not nip
the antenna projectile, so avoiding the performance of the antenna.
7) High frequency cable don’t come down directness, circle a circuit and fixup it on
the frame for the best.

10.Application of KYL-600L Networking
The communication channel of KYL-600L is half duplex, which is most suitable for
the communication mode of point to multi-point. Under this mode, one master station
must be set, and all of the rest are slave stations. A unique address is given to each
station. The coordination of communication is controlled by master station that uses
data frames containing address code to transmit data or command. Slave station will
receive all of the data and command and compare the received address code with local
address code. If they are different, the data will be deserted without any response. If
those address codes are the same, it means the data is sent to the local. Slave station
will make different responses according to the transmitted data or command and send
back the data of response. All these jobs must be performed by upper protocol, and it
is assured that there is only one transmitter-receiver in the state of transmission in the
communication network at any instant moment so as to avoid the cross-interference.
KYL-600L can also be used for point-to- point communication with easier operation.
For the programming of serial port, all you have to do is to remember that its
communication mode is semi duplex while always observing the time sequence of
come-and-go for receiving and transmitting.
