The SH ARC-PC104 is an ARCNET card for systems with PC/104 bus. You may select the interface modules as you wish. They are connected with the basis card by means of a ribbon cable. The modules can be integrated in a PC/104 processor system at any place (either at the plug or with the help of two fastening angles).

A service LED onboard the interface modules signals the receiving activity in operation. The design meets EMC standards suitable for use in rough industrial environments.

SH ARC-PC104 uses the same standardized driver interface as the other SOHARD ARCNET cards.

The following components are on the card:

ARCNET controller

On the card is installed the ARCNET controller COM20022 from SMSC that is fully compatible with the COM20020. Supported are bit rates up to 10 Mbps as well as additional settings.

PC/104 Interface

The 16 bit card allows the use of interrupts from 2 to 15. That only occupies 8 I/O addresses with flexible basis address (compatible to 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. Currently fiber optic, coaxial and RS-485 modules are available. A security logic protects the coax transceiver of the interface module from being destroyed during operation by small data rates or by usage of backplane mode.
