Low Power RS232 Wireless Data Module

Instruction:

SG-500 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.

Features:

1. Power: 500mW (default), 600mW~1W (optional).

2. 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

SG-500 provides 8 channels, expandable for 16, 32 channels according to requirements of users.

7. Three connection methods with DB9 connector

SG-500 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 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

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 SG-500 transceiver automatically.

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 our modules.

14. Beautiful metal shell.
