Bisa 2.4GHz Gain Adjustable Reader adopts ultra-low power consumption design, which allows it into flammable and explosive high-risk circumstances, like the gas station, chemical factory, etc.. RS232 interface can connect reader with Control center directly; while RS485 interface makes it suitable for tree network.

Note: 
A, Reader with interface RS232 must be connected to Service directly, and the communication range between reader and service is no more than 15 meters. 
B, Reader with interface RS485 can be connected into wired network with largest communication range thousand meters. The service to reader is as host to slave in RS485 network, thus readers in such a system can’t send data to service actively but only send after receiving command from service.  Thus the RS485 readers in system only use buff mode to communicate. Direct mode in RS485 reader is just for single reader demonstration.

Network structure of RS485 reader

Functions:
RS232/485 Reader RF frequency is 2.45GHz, belonging to global ISM frequency. The reader is read only, in other words, just collect signal from tags. It has two work modes: Direct mode and Buffer mode.

Direct mode: signal from tags would be uploaded to server immediately once received; the mode is always used in test or just controls one reader in group.

Buffer mode: signal from tags aren’t uploaded to server immediately buy saved in buff, waiting server to inquiry and get data. The mode is used in device patrol in turns. 

The reader has gain adjustable function, by which communication range can be adjusted by 32
different gains.

Provide the dynamic link library and API interface function and DEMO presentation software under WINDOWS, to facilitate secondary development for customer.
