Product information

Description

The ROLINE USB 2.0 to RS232 Adapter ROLINE 12.02.1003 provides four DB9 serial ports and a Mini USB type B connector to connect legacy RS232 devices to a PC USB port. The adapter supports USB 2.0/1.1/1.0 standards, offers data transfer rates up to 115200 bit/s, and includes 15 kV ESD protection on all RS232 ports. It is designed for DIN rail mounting and draws power via the Mini USB type B connector (approximately 40 mA). The adapter is compact, black in colour, and suitable for industrial and office environments where serial-to-USB conversion is required.

Advantages

This four-port adapter lets you connect multiple serial devices to a single USB port, reducing the need for additional serial interfaces. Support for USB 2.0 ensures backward compatibility with USB 1.1 and 1.0 hosts. Built-in 15 kV ESD protection helps protect connected equipment from electrostatic discharge. DIN rail mounting simplifies installation in control cabinets and industrial racks, and the low power draw from the Mini USB connector eliminates the need for an external power supply in most use cases.

Suitable for

Connecting RS232 devices (e.g., barcode scanners, PLCs, industrial sensors) to a PC
DIN rail installations in industrial control cabinets
Legacy serial device integration with modern USB-only machines
