2 Channel Fiber to RS232/RS422/RS485 Converter | Mini Type

The mini 2-channel fiber to RS232/RS422/RS485 converter breaks through the contradiction between the distance and communication rate of traditional serial interfaces. It also addresses challenges such as electromagnetic interference, ground loop interference, and lightning damage, greatly enhancing data communication reliability, security, and confidentiality.

The RS485 to fiber optic converter can be widely used in various industrial control, process control, and traffic control applications, particularly suitable for sectors and systems such as banking, power, and environments with special requirements for electromagnetic interference. It can transmit asynchronous serial data with adaptive baud rates ranging from 0 to 115200bps.

● Support RS232/RS485/RS422 interface types for each port.

● Automatically detect the baud rate of the serial signal.

● When there is no fiber optic signal detected, the device can automatically determine whether it is due to a power-off condition at the remote device or a fiber breakage. It then indicates the LED to reflect the specific situation.

● Provides lightning protection according to the IEC61000-4-5 (10/700μs) standard, with a differential mode of 6KV and impedance of 2Ω, and a common mode of 6KV and impedance of 2Ω.

● The fiber to rs485 converter can transmit asynchronous serial data with adaptive baud rates ranging from 300 to 115.2 Kbps.
