2. Frequency: 400-470MHz, 868/915MHz ISM frequency is available if
3. Long Transmission Distance (Line-of-sight Distance)
8Km (BER=10-5@9600bps, 5.5dbi clip antenna, Line-of-sight
12Km (BER=10-5@1200bps, 5.5dbi clip antenna, Line-of-sight
4. Multi-channels,Multi Baud rate
Offer 8 channels, if needed, 16 or 32 channels are available to
satisfy various configuration of communication under user's demand
at the same time.
Baud Rate: 1200/2400/4800/9600/19200/38400bps etc.
5. High speed wireless communication and Big data buffer area
When air baud rate is greater than interface baud rate, unlimited
data can be continuously transmitted. When baud rate is less than
or equal to interface baud rate, can transmit one frame 128 bytes
6. Intelligent data control and no any extra programs required
Even for half duplex communication, no any excessive programs
required. All RF system data transmission/reception and other
On-the-Fly conversion and control are performed by KYL-300H
7. Lower power consumption & Sleep function
The receiving current is less than 30mA, the transmitting current
is less than 1.5A, and the sleeping current is less than 1mA.
8. High reliability, small and light

Before using KYL-320H, the user needs to make simple configuration
based on its own needs to determine the channel, interface mode and
data format. The user can change or view the module's interface
baud rate, channel and address code. Parameter setting or reading
as per the testing software KYLPRO.exe in the PC (in products box).
When the air baud rate is greater than the interface baud rate, one
frame can transmit unlimited data, and the air baud rate is less
than or equal to the interface baud rate. A frame can transmit up
to 255 bytes. The higher the air baud rate is, the closer the
transmission distance will be.
When using 2pcs KYL-320H, the parameters must be configured as
follows (Our company will normally configure the parameters
according to the user's needs):
1. The same channel (ie, frequency);
2. The same air baud rate;
3. The interface baud rate and parity bit are consistent with the
connected device or computer.
Software operation (see "Software Operating Instructions" for
After entering setup software, Click "open port",
Click "read radio station in file". After successful detection,
click "read parameters", "Read correct" show your connection
between KYL module and PC is correct.
Click "Settings" to set up successfully.
1. In order to achieve the best communication effect, please use a
power supply with a smaller ripple factor as much as possible. The
maximum output current of the power supply should be more than 1.5
times the maximum operating current of the module.
2. For TTL, RS-485, RS-232 interfaces, one of them can be choosed
3. Baud rate: Interface baud rate: the user can change it in
KYLPRO.exe PC software; Air baud rate: can not be changed after
4. The Pin8 "SLP" in JP1 is the signal of sleep control. In high
power level, transceiver stays in working mode. In low power level
[<0.5V], transceiver stays in sleep mode. The SLP signal can
convert transceiver from working to sleep mode in 1ms after falling
edge. If the sleep signal arrives when the transceiver is
transmitting data, the module will enter sleep mode after finishing
transmission. From sleep mode to working, it takes the transceiver
1ms after rising edge. To disable the opened sleep function of
KYL-300H, the SLP (SLEEP) pin should be definitely connected with 0
