Data Transit Corporation Announces Bus Doctor™ Rx

Sleek New Design Combines Portability With Robust Lab Capabilities

SAN JOSE, Calif. (January 31, 2003) -- Data Transit Corporation, the leading supplier of modular bus protocol analyzers, today announced availability of the Bus Doctor Rx, Data Transit's most versatile protocol analyzer to date, featuring a sleek new design, portability and robust lab capabilities. The Bus Doctor Rx is the first analyzer to test up to eight different bus types simultaneously. Its advanced software features use a common interface for multiple bus types correlating and synchronizing signals to capture them on the same reference clock.

"We developed the Bus Doctor Rx for clients that need a flexible solution," said Dennis Evans, president and COO, Data Transit Corporation. "It is the first protocol analyzer with the ability to combine and analyze eight different bus types and yet, we've made it as portable as a laptop to help field reps perform protocol analysis at important, on-site installations."

The Bus Doctor Rx offers unprecedented configuration options. It operates independently or in combination simultaneously with up to eight Bus Doctor Rx analyzers, allowing engineers to study any combination of eight bus types. The Bus Doctor Rx connects to laptop or desktop computers using a USB 2.0 connection.

"In addition to its portability, the Bus Doctor Rx is designed for network-intensive applications," said Dale Smith, chairman and CEO, Data Transit Corporation. "By allowing engineers to analyze up to 16 ports of Fibre Channel at one time, the Bus Doctor Rx is the ultimate SAN protocol analyzer for today's network environment."

Typical applications include viewing up to sixteen ports of a Fibre Channel arbitrated loop, or analyzing both sides of a Host Bus Adapter - such as PCI-to-SCSI. Other applications include identifying the sources of delay as data is translated from one bus to another, troubleshooting problems created when separate busses request the same system resources, or comparing the utilization of different bus segments. The Bus Doctor Rx is well suited for optimizing performance in a RAID system, analyzing primary and secondary ATA busses or for analyzing multiple nodes of a network or SAN.

Bus Doctor software is designed for use with multiple monitors on all the busses under test. It also has a single interleaved, color-coded display format showing all of the captured traces on a single display. With Bus Doctor software, when engineers simply double-click any of the individual bus Command Listings, State Listings or Waveform displays - or the Unified Display - the displays become synchronized for all the busses to the same point in time. The software also allows for the generation of any trigger event established for any of the busses.

The new Bus Doctor Rx uses the same bus pods as Data Transit's 36- and 108-Channel Bus Doctor Analyzers and can support any combination of these pods, including: ATA/ATAPI, USB 1.1 & USB 2.0, SCSI-1 through 320, 1394a, PCI thru PCI-X, PCMCIA, Compact Flash, CardBus, Fibre Channel, Gigabit Ethernet with iSCSI, InfiniBand™ 1X and 4X, Serial ATA (SATA) and Serial Attached SCSI (SAS). As with all of the Bus Doctors, the Rx can also perform Logic Analysis.

The Bus Doctor Rx comes in three versions, differing in trace buffer size. Each version may be ordered with a buffer for dedicated trace memory to accommodate 16-, 64- or 256-million events.

Data Transit is currently shipping the Bus Doctor Rx. For further information please contact Data Transit at 408.279.1555 or www.datatransit.com.
