Released on 07/05/2013
Major Update

Release Changes

New Features

Multi-source Monitoring
Device Monitoring Studio supports joining monitored data from multiple sources of the same type into a single monitoring session. It is possible to monitor two or more serial ports, USB devices or network adapters. Device Monitoring Studio makes sure packets are correctly sorted and presented through a number of supported data visualizers. Data logging also supports multi-source sessions.
Remote Monitoring
DMS 7 supports monitoring USB and serial devices connected to remote servers. A single client may monitor several servers and a single server may be monitored by multiple clients. A separate server installation is provided. It includes a server access module, serial and usb monitoring modules, administration and management module and documentation. A server is managed using the MMC Snap-In or from Windows Scripting Host or PowerShell.
Windows 8 Support
DMS 7 officially supports Windows 8 and Windows Server 2012.
USB 3.0 Support
USB Monitor introduces support for USB 3.0 host controllers and devices.
Built-In and Custom Protocol Parsing
DMS 7 extends protocol parsing support for all monitoring modules: network, USB and serial. In addition, this version has new implementation of protocol parsing, which is more flexible and greatly improves performance.
New Data Processing Category
New processing category is introduced: data exporters. These are components that process monitored data in some way, but do not produce any visible output on the screen. Data recording module now belongs to this category. Other data exporters are Raw Data Exporter and Text Exporter. Both these exporters are capable of using built-in or custom protocol definitions to parse monitoring data before exporting.
Parallel Processing
New version of Device Monitoring Studio utilizes multiple cores for more responsive monitoring session operation. It basically allows the user to still perform real-time monitoring of 1 Gb network transfer without packet loss and slowdowns while having such "heavy" processing like Capture Filter and Display Filter configured for a monitoring session.
Device Tool Window
New tool window that displays all devices the user can monitor in a single customizable view. For each supported device, its image, type and current state are displayed. The user may start, stop and configure monitoring sessions, view device properties, restart and rename devices.
Sessions Tool Window
New tool window lists all currently running sessions and their properties. It allows you to close data visualizers, add new data processing modules, pause, resume or stop sessions. It also allows you to quickly change data processing modules configuration. For example, for data recording, the current log file size is displayed. By clicking "End Stream", the user ends the current stream and starts a new one.
Protocol-Based Data Visualizers
Structure View and Raw Data View data visualizers for USB, Serial and Network with additional filtering (Display Filter) and ability to specify root protocol.
Automatic Layout Loading
DMS 7 automatically loads separate tool window and command layout when monitoring session is started. Thus, until a session is started, a layout which simplifies device discovery and information retrieval is used. After the session is started, another layout is automatically loaded streamlining monitoring session usage. Both layouts may be customized by the user.
Global Configuration Switch
Device Monitoring Studio provides you with a global switch to quickly turn it into Serial Monitor, USB Monitor or Network Monitor. This switch may be used in combi installations to temporary hide unneeded components.

Updated Features

Session Configuration Window

New Session Configuration window greatly simplifies session creation and modification. There is a list of configured sources at the top of the window. Below are optional device configuration settings, buttons to add more devices and remove existing ones.

Depending on the type and number of configured sources, a list of available processing modules is populated. It is divided into two main categories: visualizers and exporters.

Double-click on the processing module to add it to the current session. Some of modules support configuration. Customized processing modules may be saved for future use.

Finally, the user specifies a capture filter, a generic (protocol-based) conditional expression used to filter out specific monitored packets.

New data visualizer: Structure View (USB)
New data visualizer has been added to USB Monitor. It parses monitored data according to a set of loaded protocol definition files and displays the parsed data in tree view and raw binary view.
Capture filter (USB)
It is now possible to define a capture filter — an expression which is evaluated against each monitored packet. If expression's result is false, the packet is discarded, otherwise, it is sent for further processing.
Display filter and root protocol (USB)
Each opened Structure View window may additionally have its own "display filter" to further filter incoming data. In addition, each window may use its own "root" protocol for each monitored packet.
Custom protocol (USB)
In addition to a set of pre-defined protocols, a user may now create his own protocol definition files and have USB Monitor automatically parse monitored data according to them. Capture and display filters are also capable of using these new protocol definitions in their expressions.

Alternatively, the stream may be displayed as a sequence of floating-point numbers with single or double precision.

This new data visualizer is very flexible and allows you to customize both its layout and appearance. It has a built-in pattern coloring, powerful find capabilities and Clipboard/exporting support.

Released on 09/28/2007

Release Changes

New Features

Automatic Data Policy Management

There has always been a feature in the Device Monitoring Studio, called "Data Processing". It could be and still can be used to control the data processing policy. You can trade disk space usage for a session history length. More disk space you allow Device Monitoring Studio to use, more older session packets are available for you.

Version 5.22 introduces an automatic data policy management for monitoring sessions. If only Logging and/or Statistics visualizer are configured for the monitoring session, it is forced to low disk space usage policy. If any other visualizer is configured for the monitoring session, it falls back to the setting, defined by the user.

High-Speed operation mode
The High-Speed mode is automatically enabled for a session, for which only the Statistics visualizer is configured. In this mode the amount of data analyzed by the application is reduced significantly, leading to more accurate performance measurements. This mode is useful if you have a device with extremely high transfer rate (more than 16 MB/s) and want to measure its performance.

Performance optimization
The performance of the USB Monitor module was increased.
