| Data transmission resolutions |
In the field of automation, many equipments including reader, sensor, and parking lot gateway are able to transmit collected data from device to server or from server to device through adapters across floors, buildings, or the offshore office via Internet connection. RS-232, RS-422, RS-485, and MP-521G gateways are the interfaces usually applied to resolve the problem of transmission in distance.
MP-521G gateway can be easily programmed through a browser. The modern style with complete functions and flexible configuration of MP-521G is capable to adapt to connections in different environments easily in a short period of time and to simplify signal transmission.
The reliable MP-521G gateway contains excellent protection for power reverse connection or overloading; moreover, the interchangeable three interfaces (RS232, RS485, and IO) perform excellently. |
