• UT-1304 is a bus-splitting hub designed with an internal microprocessor (uninterrupted operation) to meet the requirements of RS-485/422 systems in complex electromagnetic fields.
• Outdoor usage: RS-485/422 connector uses photoelectric isolation technology to prevent lightning surge from introducing converters and devices, which can effectively suppress lightning and ESD. Ideal for outdoor applications.
• Discriminant circuit: In RS-485/422 operation mode, the discriminant circuit used can automatically sense the direction of data flow, and automatic switching enables the control of the circuit, which can easily solve the problem of transmission and reception delay.
• Stable performance: RS-485/422 interface transmission distance is greater than 1.2 km. RS-485 Hub is a high performance data interface conversion product, widely used in highway toll collection, monitoring system.
• Reliability: Each port is protected by short circuit and open circuit. When lightning strikes or device failures occur, the problem segment will be isolated to ensure that other segments are working properly.
