2. Features of YS-C10L

1. Low power transmission with 400mW.

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 onthe Gaussian Frequency Shift Keying (GFSK) modulation, the high-efficiency forwarderror correction channel encoding technology is used to enhance data’sresistance to both transient interference and random interference and the actualbit error rate of 10-5 ~ 10-6 can be achieved whenchannel bit error rate is 10-2.

4. Long Transmission Distance

Within thevisible range, when the height of antenna is higher than 2m and The Bit Error Rate(BER) is 10-3, the reliable transmission distancesrespectively is 2km @1200bps, and is 1.5km@9600bps.

5. Transparent data transmission

Transparentdata interface used in transceivers is for meeting many standard or nonstandarduser 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-C10Ltransceivers offer 8 channels, if needed, 16 or 32 channels are available tosatisfy various configuration of communication under user’s demand at the sametime.

7. Big data buffer area

Withoptional interface baud rate: 1200/4800/9600/19200bps and 8N1/8E1/8O1 data format(set by user), the transceiver can transmit unlimited data frames with flexibleuser program.

8. Intelligent data control and no any extra programsrequired

Even forhalf duplex communication, no any excessive programs required. All RF system datatransmission/reception and other On-the-Fly conversion and control areperformed by YS-C10L transceivers automatically.

8. Lower power consumption & Sleep function

With +3.3Vto +3.6V power, the receiving current is less than 25mA, the transmittingcurrent 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.

V. Networking Application of YS-C10L

Thecommunication channel of YS-C10L is half duplex, which is most suitable for thecommunication mode of point to multi-point. Under this mode, one master stationmust be set, and all of the rest are slave stations. A unique address is givento each station. The coordination of communication is controlled by masterstation that uses data frames containing address code to transmit data orcommand. Slave station will receive all of the data and command and compare thereceived address code with local address code. If they are different, the datawill be deserted without any response. If those address codes are the same, itmeans the data is sent to the local. Slave station will make differentresponses according to the transmitted data or command and send back the dataof response. All these jobs must be performed by upper protocol, and it isassured that there is only one transmitter-receiver in the state oftransmission in the communication network at any instant moment so as to avoidthe cross-interference.

YS-C10Lcan also be used for point-to-point communication with easier operation. Forthe programming of serial port, all you have to do is to remember that itscommunication mode is semi duplex while always observing the time sequence ofcome-and-go for receiving and transmitting.
