RS-232/422/485 to Fiber


Industrial Serial RS-232/422/485 to Fiber Converter

The standard RS-232/422/485 protocols and interfaces have been widely used in most of industrial equipments for serial port communication. The fiber media material offers ideal insulation and long distance advantages for data transmission. The AMC-5910 series combine many advantages of RS-232/422/485 and fiber media for serial communication. The Peer to Peer (PTP) and Serial Fiber Ring (SFR) modes are typical application modes in the networking communication. The serial interface mode and optical mode are easy setting with DIP switch.

Automatic Direction and High Speed Transmission

The AMC-5910 series support RS-232, RS-422, half-duplex 2-wire RS-485 and full-duplex 4-wire RS-485 to fiber media converter.

The RS-485 offers the automatic data direction control feature. The data rate supports up to 115.2Kbps, satisfying the need of most automatic control systems.

Wide range Power Input, Temperature, and Insulation Protection

The wide range DC power input from 12V to 48V, this wide range DC power input supports the demanding of versatile industrial applications.

Most of industrial applications are harsh environment, The AMC-5910 series provide the operating temperature from -40 to 70。C, give you a reliable solution of a RS-232/RS-422/485 to fiber media converter for wide temperature application. The AMC-5910 series provide full insulation between two devices with fiber media, every AMC-5910 have 15K ESD protection on the RS-422/485 signal lines.

Peer to Peer (PTP) and Serial Fiber Ring (SFR) modes

The PTP mode offers fiber media transmission between two devices, it is a simply application for fiber full duplex communication.

The SFR mode offers ring transmission from 5km to 100km distance. It only allows half-duplex communication among devices.
