Features

1. Micro power transmission

The maximum transmission power is 2W.

 

2. Built-in and modularized design

FC-203/SA can be embedded into the system of user as an independent communication unit.

 

3. High anti-interference and low BER(Bit error Rate).

Based on narrowband channel and the FSK modulation mode, adopt high-efficiency FEC channel encoding technology to enhance data’s resistance to both burst interference and random interference.

 

4. Transparent data transmission

Adopt transparent data interface to meet any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted).

 

5. Multi-channel

The standard FC-203/SA configuration provides 16 channels. If the user needs, it can be extended to 32 channels, meeting the multiple communication combination mode of the user.

 

6. Interface modes

FC-203/SA can provide transparent UART/TTL interfaces and audio interface. Meet the demand of data transmission and voice transmission.

 

7. Large data buffer

The interface rate is 9600bps, format is 8N1/8E1/8O1;user can set through software,FC-203/SA can transmit more than 214 bytes long data frames at one time in any case. If the RF data rate is greater than the interface rate, it can transmit infinitely long data frames.

 

8. Low power consumption

Receiving current is <80mA, transmitting current is <800mA

 

9. Providing RSSI and SQ output

FC-203/SA can offer SQ (Output is high if signal in-band is detected, low if no signal detected) and RSSI (analog output with range of 60dB) to user for deep development or route testing.

 

10. High reliability, small and light

TCXO and all-metal housing structure used in FC-203/SA for high reliability and low failure rate.

 

11. Customization for special antenna

Various antenna can be designed and customized for special requirement.
