UOTEK RS-232 RS-485 RS-422 Fiber Optic Modem - Fast Internet Speed & No Lag

Support RS-232, RS-485, RS-422 asynchronous communication protocols

Can mix two RS-232, RS-485 or RS-422 interfaces at the same time.

Supports 2-wire (half-duplex) RS-485 and 4-wire (full-duplex) RS-422 operating modes.

Supports data (TXD or SD) transmission control.

This improves the ability to adapt to various types of software and simplifies the control method.

Supports multiple fiber optic connections between asynchronous serial ports

It supports full-duplex or half-duplex communication between two devices with asynchronous serial ports via optical fiber, with a communication distance of up to 20 km in single mode, and a transmission rate of 115.2Kbps for RS-232 signals and 460Kbps for RS-485/RS-422 signals.

The interfaces of different electrical standards can be mixed

RS-232 devices can be used to connect RS-485/RS-422 devices, which can replace RS-232 to RS-485/422 interface converters or optoisolators, and provide EMI/RFT characteristics.

Support 2 data signal transmission

Transmitting data and receiving data, and also provides automatic enable control circuit for data transmission of RS-485/RS 422.

Zero-delay conversion

All serial ports are connected via terminal blocks, and the fiber optic connection is through two ST connectors.

It is the best choice for connecting remote terminal unit (RTU) to host computer (HOST) or distributed data acquisition system (SCADA) controller.


Single-mode communication distance up to 20 km	Equipped with power adapter	Wide range of applications

Singlemode Fiber Optic Transceiver - Generally used in pairs

RXD:

Blinking: means no data is being sent from the fiber port
Out: means no data on the fiber port
Always on: means the serial port is connected backwards or below the bus detection voltage

TXD:

Blinking: means no data is being sent from the fiber port
Out: means no data on the fiber port
Always on: means the fiber is not working or reversed

PWR:

Always on: means the power supply is normal
Off: means the power supply is not normal

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