The ZP-3372SM is a fiber optic modem capable of providing RS-232/485/422 serial port end-to-end transparent transmission without jumper setting, automatic switching, and automatic detection of signal rate and zero delay auto-forwarding. The product uses optical fiber transmission, with isolation protection, data confidentiality is good, stable, easy to maintain and many other advantages, effectively avoid the harsh environment of lightning, surge and electromagnetic interference and other communications equipment threat, can be reliable in the bad Working in a dangerous environment. Multifunctional fiber optic MODEM for asynchronous RS-232, RS-485, RS-422 communication interface is the best choice for connecting remote terminal units (RTU) to host (HOST) or distributed data acquisition system (SCADA) controllers The Support RS-232, RS-485, RS-422 multiple asynchronous communication protocol, you can mix two RS-232, RS-485 or RS-422 interface, support 2-wire (half duplex) RS-485 and 4 Line (full duplex) RS-422 working mode. The RS-485 mode of the product supports data (TXD or SD) transmission control, thus improving the ability to adapt to various types of software, but also simplifies the control mode, optical fiber MODEM support asynchronous serial port between a variety of fiber connection RS-485 / RS-422 signal transmission rate up to 500KBPS, different electrical standard interface can be used in combination, you can use the RS-485 / RS-422 signal transmission rate of up to 500KBPS, different electrical standard interface can be used in combination, you can use RS- 232 device to connect RS-485 / RS-422/232 devices, instead of RS-232 to RS-485/422 interface converters or opto-isolators, and provides excellent EMI / RFT characteristics.
Support two data signal transmission: send data and receive data, but also provides RS-485 / RS-422 data transmission automatically enable control circuit. Zero delay conversion time, all serial ports are connected through the terminal. Can be widely used in a variety of industrial control, process control, traffic control and intelligent community and other occasions, especially for banks, electricity and electromagnetic interference environment has special requirements of the departments and systems. Line systems, telecommunications room monitoring, power monitoring and other broadband data networks and require high reliability data transmission or the formation of IP data transmission network of industrial communications
