Scope of application
The SH ARC-PCI104 is an ARCNET card for use in PC/104-Plus or PCI-104 systems.
Unlike the SH ARC-PC104 it is connected to the host via the PCI bus. Featuring a 32 bit address bus (instead of 16 bit) it allows for higher transfer rates. Due to the form factor it can immediately replace the SH ARC-PC104 in PC/104-Plus systems. When the SOHARD RAW ARCNET driver is used, not even the software has to be changed.
The card is suited for the 3.3 V and 5 V signal environment on the PCI bus. It features a 32-Bit data bus and thus, enables high transfer rates. A boxed header allows to connect SOHARD ARCNET interface modules for the connection to ARCNET networks with various signaling methods (sine dipulse, RS-485/EIA-485, RS485AC and optical) via coaxial, twisted pair or fiber optic cables.
As the SH ARC-PCI104 covers an elevated temperature range it is well suited for usage in devices lacking forced cooling as e.g. the Siemens SIMATIC Microbox 427B.
Design & Functionality
The card features the following components:
ARCNET controller
The ARCNET controller is COM20022 from SMSC. It supports bit rates up to 10 Mbit/s as well as additional settings.
PCI/104 Interface
The card allows for the use of interrupts from 2 to 15. It occupies only 8 I/O addresses with a adjustable base address (compatible to SH ARC-ISA, formerly SH FARC E3).
Field bus connections
All interface modules (please order separately) are connected to the PC/104 card by means of a ribbon cable.
A security logic protects the dipulse transceiver of the interface module from being destroyed during operation by low data rates or by usage of backplane mode.
