I. Features of YS-C30H

1. Low power transmission with 5W, 6W~7W is available if needed.

2. With 433MHz as factory default carrier frequency, but400-470MHz 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 theactual 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 10km @1200bps, and is 8km@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

YS-C30H 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. 2 ports with three connection methods

YS-C30H transceivers provide 2 ports with three connections, ports: a UART interface of TTL level, a non-standard RS-232 port and a non-standard RS-485 port.

8. 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.

Note: the RF data rate is only settled down before delivery, please inform our sales when placing your orders.

9. 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 YS-C30H transceivers automatically.

10. Lower power consumption & Sleep function

With +12V power, the receiving current is less than 30mA, the transmitting current is less than 1.5A, and the sleeping current is less than 1mA.

11. High reliability, small and light

By using monolithic radio-frequency integrated circuit and single-chip MCU, the

transceivers have less peripheral circuit s, high reliability, and low failure rate.

12. More options of configurable antennas for user different applications.
