Scope of application

The SH ARC-PCIe ARCNET card series has been developed for use in industrial PCs that feature the PCI Express bus. The cards are available with coaxial interface, galvanically decoupled RS-485/EIA-485 interface or as compound cards featuring different ARCNET interfaces for connection to ARCNET networks with various signaling methods (Sine dipulse, RS-485AC and optical) via coaxial, twisted pair or fiber optic cables.

When you update to a PC with PCI Express interface the card can immediately substitute other SOHARD ARCNET network adapters, if your application is using the SOHARD RAW ARCNET interface and the corresponding driver.

Design & Functionality

The card features the ARCNET controller COM20022 from SMSC. It supports standardized bit rates up to 10 Mbit/s. The SH ARC-PCIe is a 32 bit card conforming to PCI Express 1.0a. The card is a plug and play device. Configuration of addresses and interrupts is simple. It may be addressed via I/O addresses or via memory.

4 LEDs indicate the following activities:

  • Coaxial transceiver active/inactive (back plane mode on/off).
  • Activity on ARCNET receive channel
  • Activity on ARCNET transmission channel
  • PC access to ARCNET module
