Scope of application

SH ARCALYZER is a universal analyzer for ARCNET networks which use bit rates from 19 kbit/s up to 10 Mbit/s. The analyzer is available as PCMCIA or USB device.

The SH ARCALYZER can be used

  • during development to debug products containing error-prone ARCNET interfaces.
  • during the installation of and for for the acceptance test of networks
  • for error investigation in existing networks and
  • for proving manipulation of network hardware and cabling


SH ARCALYZER is available with different ARCNET interfaces for connection to ARCNET networks with various signaling methods (sine dipulse, RS-485/EIA-485 (DC and AC) and optical) via coaxial, twisted pair or fiber optic cables. It is delivered with software for Windows 2000, Windows XP, Windows Vista and Windows 7.

Common ARCNET analyzers normally use ARCNET controller chips as e.g. the COM20020, thus offering only limited functionality. On the other hand SH ARCALYZER comprehends a hardware specially developed for analyzing ARCNET networks. A 2 Mbit buffer (FIFO) on the card ensures that no data will be lost when applying high data rates and using non-real time operating systems.

Design & Functionality

Main Dialog

The Main Dialog is the Control Center of SH ARCALYZER. It provides access to various functions and allows to make global settings for bit rate and timeout.

Protocol Monitor

The Protocol Monitor captures, time-stamps and lists all of the ARCNET protocol elements (ITT, FBE, ACK, NAK, RECON and PAC) transmitted on the network as well as corrupted and thus not identifiable elements. Extensive filters allow for selective capture and displaying. A powerful search function allows to find patterns in data packets. A status column displays additional relevant information on the protocol elements such as timeouts, CRC errors, the number of transmission attempts, etc. The ARCNET data capture can be triggered by external or internal events.

Global Statistics

Numerous event counters offer a quick overview, e.g., of the number of reconfigurations, packets etc. There are global counters as well as counters assigned to single nodes.

Net Map

The Net Map allows to recognize at one glance, which nodes are currently within the network as well as their current status. The snapshot function freezes the status quo. Deviations from this status will be highlighted to show if nodes have left or entered the network. Even the one node in a single-node 'network' is displayed. It is possible to visualize special information on each node in the Net Map, e.g. its part in the transfer of data packages (PACs), what allows to recognize which nodes stress the network at which scale. FBEs, PACs, NAKs and other protocol elements can be analyzed the same way.


The Fingerprint function allows to record the characteristics of a network into a fingerprint file, e.g. during the acceptance test or when the network will handed over to the costumer. Subsequent hardware and cabling manipulations can be proved by comparing the primary fingerprint to the current fingerprint of the network.


The Log registers all important events in the network: reconfigurations, nodes entering or leaving the network, as well as various error messages.
