Scope of application

The SH ARC-USB family has been developed as USB ARCNET adapters for use in industrial environments. The devices are available with various ARCNET interfaces for connection to ARCNET networks with different signaling methods (sine dipulse, RS-485 (EIA-485), RS485AC and optical) via coaxial, twisted pair or fiber optic cables.

If you use other SOHARD ARCNET network adapters in combination with the SOHARD RAW ARCNET interface and the corresponding driver then they can be immediately substituted by the SH ARC-USB and its driver. Your application needs not to be changed.

Design & Functionality

The SH ARC-USB features the FPGA-based ARCNET IP core SH IP-CORE-ARCCTRL that is thoroughly compatible to the ARCNET standard. SH ARC-USB meets the USB Standard 2.0. The device is housed in a solid metal casing. The SH ARC-USB is available with various ARCNET interfaces (see order information). A specialty within this product series is the SH ARC-USB-K which comes either in a particularly compact casing or as a low-profile plug-in board for standard as well as low-profile PCs.
