UOTEK RS232 RS485 to Fiber Optical Converter, RS232 RS485/422 to Fiber Optics

UOTEK RS232 RS485 to Fiber Optical Converter, RS232 RS485/422 to Fiber Optics Industrial Grade RS232/485/422 to Optical Fiber Modem SC (UT-277SM-SC)

• Communication rate up to 460Kbps
• Optional SC, FC, ST interfaces are available
• Support point-to-point (point-to-multipoint) connection
• Support RS-232, RS-422 and RS-485 asynchronous communication protocols
• Supports 2-wire (half-duplex) and 4-wire (full-duplex) RS-485 operation

Overview
●UT-277 is a multi-functional fiber optic MODEM supporting asynchronous RS-232, RS-485, RS-422 communication interfaces, which is the best choice for connecting remote terminal unit (RTU) to host computer (HOST) or distributed data acquisition system (SCADA) controller.
●UT-277 RS-485 way to support data (TXD or SD) to send control, thus improving the ability to adapt to various types of software, but also simplifies the control mode.
●Fiber optic MODEM support asynchronous serial port between a variety of fiber optic connection, it supports two asynchronous serial port devices through the fiber optic full-duplex or half-duplex communication, communication distance up to 4 km multi-mode, single-mode 20 km.

Specification
● Simultaneous use of RS-232, RS-422 and RS-485 interfaces
● Supports master-slave mode
● Slave mode can be used as repeater
