Product Description
ATC-873 wireless digital transmission module offers standard RS-232, RS-485 and UART/TTL level interfaces for direct connection with computers, use's RS-485 equipments, SCM or other UART parts.
ATC-873 has adopted half duplex communication channel most suitable for point to multi-point communication mode. The primary station takes full control of communication harmony, and adopts data frames with address codes for data or command transmitting. The secondary station shall fully receive them and select response by comparing address codes; all the work shall be fulfilled by upper layer protocols, which shall ensure that only one wireless module in the communication network is in the transmitting state in any instant to avoid mutual interference.
Therefore, the transmission channel built by ATC-873 is transparent to the user. ATC-873 can also be applied to point to point communication, making it easier and smoothly upgrade wire (RS232/485/TTL) transmission mode in original system.
Product Features
1. Ultra low power transmission
ATC-873 Transmission power less than of 100mW, high receiving sensitivity: -123dbm
2. ISM frequency band, not requiring on application of frequency point
Carrier frequency of 433MHz,also capable of providing 315/868/915MHz carrier frequency.
3. High ani-interference and low BER (Bit error Rate)
Based on the GFSK modulation mode, it adopts the efficient communication protocol. The actual 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 range of visibility, the reliable transmission distance is >300m when the antenna height is greater than >3m
5. Transparent data transmission
Transparent data interface is offered to suit 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). The charge time for receiving and sending <10ms.
6. Multi-channel and speed
The standard ATC-873 configuration provides 8 channels. ATC-873 configuration provides 16 channels. to meet the multiple communication combination mode of the users. It has baud rate to be chosen such as 1200bps, 2400bps, 4800bps, 9600bps, 19200bps, 38400bps. The wireless transmission rate is direct ratio with baud rate of interface to meet user's equipment requirement.
7. Low power consumption
Receiving current<20mA,transmission current<40mA,sleeping current <1uA.
8. High speed wireless communication and large data buffer
When the speed rate in the air is quicker than interface's, allowing to transmit unlimited length data at one time, when the speed rate is slower or equal the interface's, allowing the transmission of 255 Bytes long data frames at one time for more flexible programming by users.
9. Intelligent data control and the user doesn't need to prepare excessive programs
Even for semi duplex communication, the user doesn't need to prepare excessive programs, only receiving/transmitting the data from the interface. Module will automatically complete the other operations, such as transmission /receiving conversion in the air, control, etc.
10. High reliability, small and light
Single chip radio- frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate.
11. Watchdog monitor
Watchdog monitors the inner function, so that change the traditional product structure and improve the product reliability.
12. Antenna choose
Users can choose various antenna-setting project and antenna according to user's different need to achieve a optimal effect.
