This RS-485/422 to RS-485/422 converter automatically controls RS-485 transmitter-enable independent of baud rate, without software or jumpers. It automatically controls the direction of serial data eliminating the need for software flow control, uses a patented technique to  automatically adapt to any baud rate up to 115,200 baud and is independent of communications protocol. It has a max range of 4000 feet and operating temperature of -25°C to 80°C.  Choose isolated or not isolated, and parallel or vertical entry for the RS-485/422 termination plug. It has a stainless steel enclosure and operates from a 9-24 Vac - Vdc wall plug adapter.

• Omni-Isolation™ Optical and transformer isolation technology provide up to 2000 volts of signal and ground isolation between the computer and equipment. Eliminates ground loops that destroy computer ports and reduce serial communications reliability.

• ADFC™ ADFC™ (Automatic Data Flow Control), uses a technique protected by U.S. patent no. 5,729,547 that automatically senses and controls the direction of RS-485 data eliminating the need for software control.

• 3-in-1 Signal Conversion Converts RS-232 to RS-485, RS-232 to RS-422 or RS-485 to RS-422. Automatically senses RS-422 four-wire operation.

• Status LEDs Status LEDs are provided on both sides of the isolation for the Power, Transmit and Receive signals. These are handy for verifying operation and troubleshooting network problems.

• Transient Voltage Protection All signal and power lines are protected against transient voltages.

• Switch Selectable Termination and Bias Resistors Network termination and bias can easily be configured with DIP switches available from the outside the converter case. The switches are clearly identified on the label for easy setup.

• DTE-DCE Selection A switch easily makes the ESI either a DTE or a DCE device so the unit will communicate with a DCE or DTE device, or operate with a “straight-through” or “null modem” cable.

• Echo With the echo feature enabled, data is echoed back to the equipment side port. This may desirable or required with some protocols. The default is no echo.

• Baud Rate Independent No switches or jumpers to set. Automatically adapts to all standard and non-standard baud rates up to 115,200 baud.

• Versatile Power Supply The unit can be powered by a wide range of AC or DC voltages. Wall-plug adapters are available from duTec or others. A pluggable screw terminal is also provided for use with other power supplies. 7 to 24 volts AC or 9 to 36 volts DC @ 120mA max.

• Pluggable Terminal Blocks Industrial rated pluggable terminal blocks for ease of installation or removal. Accepts up to 16 AWG wire.

• DIN Rail Mounting DIN Rail mounting accessories available for easy wiring.
