ARCNET PCI Express Mini Card

Key Features

  • 32 bit bus
  • Using single PCIe lane (PCIe x1)
  • ARCNET controller COM20022
  • Bit rates 156 kbit/s to 10 Mbit/s
  • Mapping of the COM20022 registers into the I/O and memory space of the PC
  • Fast controller access via Advanced-Memory Mode
  • High Impedance Transmitters in a interface module will be protected against invalid bit rate and transmission mode
  • SOHARD ARCNET interface-module or costumer-specific ARCNET interface module will be connected by means of a 14 pin connector

Scope of Application

The SH ARC-MiniPCIe has been developed for use in Industrial PCs featuring PCI Express for Mini Cards. The card will be connected to a customer-specific ARCNET interface module that we will design according to your requirements as to form and signalling method (Sine dipulse, RS485, RS-485AC and optical) via coaxial, twisted pair or fiber optic cables.

Our existing ARCNET interface modules may also be built into your PC and be controlled by the SH ARC-MiniPCIe.

When you change to a PC with PCI Express Mini Card interface the card can immediately substitute other SOHARD ARCNET network adapters, if your application uses the SOHARD ARCNET RAW driver.

Design and Functionality

The SH ARC-MiniPCIe features SMSC/Microchip's ARCNET Controller COM20022 which support bit rates up to 10Mbit/s.

The card has a 32 Bit data and address bus and may be accessed to either via I/O or memory. It conforms to the PCI Express Specification 1.0a and the PCI Express Mini Card Electromechanical Specification 1.1
