UT-277SM fiber optic modem supports asynchronous RS-232/485/422 communication. It is the choice to connect remote terminal unit (RTU) with HOST or SCADA controller. It supports RS-232/485/422 asynchronous protocols; it can be mixed and matched to use 2 RS-232, RS-485 or RS-422 ports, and it supports 2 wires (half-duplex) RS-485 and 4 wires (full-duplex) RS-422 mode. The RS-485 mode supports data transmission (TXD or SD) control, this enhance the adaptation to most of the software. Fiber optic MODEM supports lots of optic connection between asynchronous serial ports. It supports 2 asynchronous serial devices to communicate under full-duplex or half-duplex via optic fiber; the communication distance can be as far as 4km at multimode, and 20km at single mode. The fastest transmission rate for RS-232 can be 115.2Kbps, and for RS-485/422 can be 460Kbps. Ports with different electronic standards can be mixed and matched to use; it is without problem to connect RS-232 devices with RS-485/422 devices. This is a good replacement of RS-232 to RS485/422 converter, which with EMI/RFT features., UT-277SM supports two signal data transmission: transmit and receive data. At the same time, it is with RS-485/422 data transmission auto control circuit; Zero delay conversion; all the serial ports is connected via terminal block. Supports RS-232/RS-485/RS-422 ports Asynchronous transmission: point to point, 460kbps Transmission distance: Single mode: 20,000 Wavelength: 1,310nm/1,550nm (single mode) Interface: RS-232: Terminal block RS-485/422: Terminal block Fiber port: ST RS-232: standard RS-232 3 wires ±15KV ESD protection, as high as 115.2kbps transmission rate. Input voltage: DC9-48V 200mA RS-485/422: auto negotiation, no need switch setting, ±15KV ESD protection Note: need 2pcs UT-277 to create communication.One for Tx; another for Rx. See more
