Low Power Wireless Transceiver 500mW Small Data Module 8 Channels
KP-RM500 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.
1. Power: 500mW (default), 600mW~1W (optional).
2. Frequency: 433MHz (default), 400-470MHz, 868MHz, 915MHz
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).
KP-RM500 provides 8 channels, expandable for 16, 32 channels
according to requirements of users.
7. Three connection methods with DB9 connector
KP-RM500 transceiver provides DB9 connector with three connections:
a non-standard RS-232 port and a non-standard RS-485 port. USB
interface port is also available. It can get power from PC
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
Even for half duplex communication, no other excessive programs are
required. All RF system data transmission/reception and other
On-the-Fly conversion and control are performed by KP-RM500
10. Lower power consumption & nice sleep function
With +5V power, the receiving current is less than 25mA, the
transmitting current is less than 300mA, and the sleeping current
is less than 20uA.
11. High reliability, small size and excellent performance
By using monolithic radio-frequency integrated circuit and
single-chip MCU, the transceivers have less peripheral circuits,
high reliability, and low failure rate.
12. Various options for configurable antennas.
13. Watchdog monitor inside
Watchdog monitors the inner operation, so it can change the
traditional product structure and also improve the reliability of
14. Beautiful metal shell.
