I: About KYL-500L
KYL-500L
KYL-500L, the micro power wireless transceiver data module is designed for
order-dish system, with the small size, weight and low power consumption and good
stability and reliability. Also it can used for the embedded system which need small
size and low power consumption and long range. Narrowband low power UHF
wireless data transmitters and receivers with channel spacing as low as 25 KHz.
II. Features of KYL-500L
1. Low power transmission with 400mW.
2. With 433MHz as factory default carrier frequency, but 400-470MHz is available if
needed.
3. High anti- interference and Low BER (Bit error Rate)
Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the
high-efficiency forward error correction channel encoding technology is used to
enhance data’s resistance to both transient interference and random interference and
the actual bit error rate of 10
-5
~ 10
-6
can be achieved when channel bit error rate is
10
-2
.
4. Long Transmission Distance
Within the visible range, when the height of antenna is higher than 2m and The Bit
Error Rate (BER) is 10
-3
, the reliable transmission distances respectively is 2km
@1200bps, and is 1.5km@9600bps.
5. Transparent data transmission
Transparent data interface used in transceivers is for meeting many standard or
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-500L transceivers 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.
7. Big data buffer area
With optional interface baud rate: 1200/4800/9600/19200bps and 8N1/8E1/8O1
data format (set by user), the transceiver can transmit unlimited data frames with
flexible user program.
8. 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-500L transceivers automatically.
8. Lower power consumption & Sleep function
With +3.3V to +3.6V power, the receiving current is less than 25mA, the
transmitting current is less than 200mA, and the sleeping current is less than 1uA.
9. High reliability, small and light
High sensitivity, suitable size for the order-dish system,
long distance, strong penetrability, suitable for handheld terminal, RSSI value.

IV. How to use KYL-500L
KYL-500L can provides RS-232,RS-485 and TTL level interface port for direct
connection with PC, RS485 devices, monolithic processors. The schematic diagram is
shown below:
1.
Power supply
The factory default setting is 3.6V. DC. By using better ripple factor, KYL-500L
transceivers can also share power supply with other equipment. If possible, a
voltage-stabilizing chip with 3.6V voltage is more recommended as the only power
supply than Switch power supply. But if only switch power supply available, the
jam by switch pulse to the transceivers should be avoided. In addition, the reliable
grounding must be used if there is other device in the system equipment. In case of

failing to connect with the ground, it can form its own grounding but must be
absolutely separated from the municipal electric supply.
2.
Connection Definition with terminal
KYL-500L transceivers supply one 9-pin connector (JP1), their definitions and
connection methods with terminals are shown in Table 1.
