low cost scsi-2 analyzer/monitor
ERLE MOTE X2509
Hurst, Texas - February 4, 1994 - Integrated Resources announces the
introduction of the PATHFINDER 2000 SCSI Bus Analyer/Monitor. Integrated
Resources is the exclusive distributor of the PATHFINDER product line,
originally developed by Workstation Products, Inc., (WPI).
The PATHFINDER 2000 is a versatile, low cost alternative to complex logic
analyzers. The PATHFINDER connects the SCSI bus to any unintelligent computer
monitor or terminal emulator and displays SCSI bus activity on the terminal's
screen in English. It's menu driven operation makes it extremely easy to use
as either an analyzer or bus usage monitor.
In analyzer mode, it has three primary capture modes: Run, Continuous and
Trigger. It then has three trigger modes: Start, Middle and End. The
PATHFINDER also has two memory usage modes: Full Data and First 32 bytes to
allow more memory for control phase capture. You can filter data to display
only specific SCSI address phases.
An example of the PATHFINDER display follows:
0000: [RESET ]
0001: [RESET ]
0002: [arbitration ]80
0003:A [selection ]81 (initiator=7,target=0)
0004:A[message out ]C0 (identify)
0005:A[message out ]01 03 01 (synchronous transfer request = 200ns) 32 08
000A: [message in ]01 03 01 (synchronous transfer request = 200ns) 32 08
000F: [command ]12 (inquiry) 00 00 00 24 00

0040: [status ]02 (check condition)
0041: [message in ]00 (command complete)
0042: [arbitration ]80
0043:A [selection ]81 (initiator=7,target=0)
0044: [message out ]C0 (identify)
0045: [command ]03 (request sense) 00 00 00 1C 00
(Down page, Up page, Goto byte, Search, Find trigger, Menu) COMMAND> Page 00
In monitor mode, it samples the bus every 78 micro-seconds, then calculates
the percent of bus usage and outputs it every second.
The PATHFINDER 2000 stores all of this information for printing and further
analysis at a later time. Developers debugging driver software or systems
administrators attempting to balance a system's load or eliminate throughput
bottlenecks will find this data invaluable.
The PATHFINDER 2000 is the successor to the PATHFINDER 1000 SCSI Bus Analyzer
which was introduced by WPI in 1991. The PATHFINDER captures up to 32K of
Single-Ended, Asynchronous or Synchronous SCSI events at speeds up to 10
MB/second.
Integrated Resources is based in Hurst, Texas, just outside of Ft. Worth and
was founded in 1987 by Carl Roberts to fill a need for VME and VXI Bus
adapters in the workstation markets. Integrated Resources also does custom
machining and manufacturing. With the addition of the PATHFINDER product line,
Integrated Resources expands its offerings and continues its tradition of
offering the greatest value and best service to the electronics industry.
The PATHFINDER 2000 with 32K SCSI event memory is available for immediate
shipment at $1895.00. Integrated Resources offers a 30 day, money-back
guarantee and a one year warranty for parts and labor. For more information,
