## Long description

ROLINE RS-232 to RS-422/485 Converter ROLINE 12.02.1008 converts RS-422 or RS-485 devices to a RS-232 port and is designed for industrial I/O applications. The compact, black housing supports DIN-rail mounting (DIN-rail kit included) or desktop use. The device uses hardware-based conversion with no software required and can be powered via the RS-232 port powered technology or optionally from an external 10–30 VDC supply.
Advantages
The converter supports high-speed communication with baud rates up to 921.6 Kbit/s and maintains data transfer up to 115.2 Kbit/s over distances up to 1.2 km. It includes selectable 120 Ω termination via DIP switch and offers extensive protection: 15 kV ESD protection on all signals and 600 W surge protection for RS-422/485 lines. Connectors are industry-standard: DB9 female for RS-232 and a 7-pin terminal block for RS-422/485.
Suitable for
 Connecting RS-422 or RS-485 field devices to RS-232 host equipment
 Long-distance serial communication up to 1.2 km
 Industrial automation, control cabinets, and DIN-rail installations

How to use
Mount the converter on a DIN rail or place it on a desktop and connect the RS-232 equipment to the DB9 female connector. Connect RS-422 or RS-485 field devices to the 7-pin terminal block according to the required signal configuration (RS-422 4-wire or RS-485 2-wire). Configure the DIP switches to enable the 120 Ω termination if needed and apply power either via the RS-232 port powered feature or by supplying 10–30 VDC to the power input. No driver or software installation is required; the device performs hardware-level conversion automatically.
Usage recommendations
For stable long-distance links, enable the 120 Ω terminator when the converter is at the end of a serial bus. Use proper grounding and cable shielding in industrial environments to maximize protection against ESD and surges. Verify wiring for 2-wire or 4-wire modes before powering the system.
