I: About KYL-300L

KYL-300L is a kind of low power wireless transceiver data module. With small size, 
low power consumption as well as good stability and reliability, it is widely used as 
wireless  data  transceiver  in  long-ranges,  narrowband low  power  UHF  wireless data 
transmitters and receivers with channel spacing as low as 25 KHz.

II: Features

of KYL-300L

:

1. Low power transmission:

500mW (default), 600mW~1W (optional).

2. Carrier  frequency:

433MHz (default),  400-470MHz,  868MHz,  915MHz

(optional)

3. High anti- interference and Low BER (Bit Error Rate)

Based  on  GFSK modulation,  high-efficiency  forward  error  correction  channel 
encoding  technology  is  used  to ensure the  data’s  resistance against both  transient 
interference and random interference. The actual BER can be achieved to 10

-5

~ 10

-6 

when channel BER is 10

-2

.

4. Long Transmission Distance

Within the visible range, when the height of antenna is higher than 2m and the BER
is  10

-3

,  the reliable  transmission  distance is  3000m @1200bps and 

2000m@9600bps respectively.   

5. Transparent data transmission

Transparent  data  interface  used  in  transceivers  is  to satisfy many  standard  and 
nonstandard  user  protocols.  Any  false  data  generated  in  air  can  be  filtrated 
automatically (What has been received is exactly what has been transmitted).

6. Multi-channels

KYL-300L  provides  8  channels,  expandable  for  16,  32  channels  according  to 
requirements of users.

7. 2 ports with three connection methods

KYL-300L transceivers provide 2 ports with three connections, a UART interface 
of  TTL  level,  a  non-standard  RS-232  port and a  non-standard  RS-485  port. USB 
interface port is also available. It can get the power for the PC directly

8. Big data buffer area

With  optional  interface  baud  rates:  1200/4800/9600/19200bps  and  8N1/8E1/8O1 
data  format  (decide by  user),  the  transceiver  can  transmit  unlimited  data  frames 
with flexible user program.

Note:

the RF data rate is only settled down before delivery; please specify our sales 

your requirements when placing your orders.

9. Intelligent data control system and no other extra programs required
