Major Update

Release Changes

This is a new major version release. The following features are new or have been significantly improved compared with the previous version:

Script Debugger

Increased support for scripting in Device Monitoring Studio calls for better tools. The built-in script editor with auto-completion support and built-in documentation is now accompanied by a script debugger.

The user may now place breakpoints, and perform stepping while debugging his scripts. The Watch tool window and Stack Trace tool window provide the detailed information about the script execution state.

New Serial Terminal

The Serial Terminal module has been redesigned and rewritten from scratch. It now provides richer API, better performance and stability and integrates with a Serial Source. This integration allows for "listening" mode monitoring sessions - a configuration when there is no active controlling application listening on the port.

In addition, terminal window is now integrated better into the application frame, is more responsive and provide better overall experience.

Data Repeater

This component, which may be attached to a serial or playback monitoring session, allows redirection of monitored traffic to one or more serial ports.

Custom View Visualizer

The Custom View data visualizer is now out of beta. It has been redesigned and is now backed by TypeScript (not internal protocol definition language). Serial's Request View and Console View have been rewritten using Custom View.

Custom View data visualizer allows the user to consume the information produced by protocol binding module and display parsed data with rich visualization capabilities.

Request View and Console View data visualizers are now powered by Custom View. Old versions of these visualizers are still available as Request View (Legacy) and Console View (Legacy).

Extended Scripting API

This release extends the list of components that may be controlled from TypeScript (JavaScript) scripts executing inside the Device Monitoring Studio:

  1. File Manager object.
  2. TCP Session, UDP Session and TCP Listener objects.
  3. Updated Serial Terminal object.
  4. New MODBUS Builder Object.

Version 7.51.00.6696

Released on 1/27/2016

Release Changes

This release is dedicated mostly to polishing various application features. It improves a lot of existing components by fixing bugs and memory leaks. It also significantly reduces application memory requirements and works around memory exhaustion issues, particularly on 32-bit systems.

New Features

This release introduces high-precision session time measurement mode. As of 7.51, this mode is supported by USB, Serial and Network modules. When enabled (per-session), Device Monitoring Studio uses high-precision system timer for packet time-stamping. This mode is enabled by default if Device Monitoring Studio is installed on Windows 7 or later.

Starting from 7.51, various device information is automatically saved to a log file if the Data Recording module is added to a monitoring session. This includes the Serial Device Information for serial devices and all kinds of USB descriptors for USB devices (Device Descriptor, Configuration Descriptor and HID Descriptor tool windows).

When resulting log file is later selected in the Devices tool window, corresponding tool windows are updated with saved information.

Raw Data View and Structure View data visualizers now support additional packet coloring mode. Now they allow the user to choose one of three modes: no coloring, packet interlacing (coloring odd and even packets) and read/write coloring (coloring read and write packets).

In addition, built-in MODBUS protocol now automatically selects RTU or ASCII mode. This works automatically in Structure View and in filters and does not affect MODBUS View data visualizer.

Fixed Bugs

This release fixes over 200 different bugs, including crashes. A special attention has been paid to the following:

  1. Monitoring session startup and shutdown-related issues, including crashes and hangs. This includes configuring and starting monitoring session, adding or removing data processing modules to running session and stopping monitoring session, as well as changing session's Capture Filter or visualizers' Display Filter for a running session.
  2. Capture and display filter performance.
  3. Protocol binding performance.
  4. Issues with various data visualizers. Almost every data visualizer has been optimized or fixed in some way.
  5. Workspace saving and loading issues.

Here is a short list of most remarkable fixed bugs:

Line View
Line View had a bug that prevented it from working. Now Line View works correctly when monitoring serial modems.
Correct emergency session termination
When resources are low, Device Monitoring Studio is now more robust in stopping affected high-data rate monitoring sessions, or session processing modules. This mostly affects 32-bit systems or systems with slow secondary storage.
Log file repairing
Device Monitoring Studio has always repaired damaged log files on startup. If log file was large, it introduced a startup delay (only splash screen was visible and application appeared to be hanging). Now a progress bar is shown to tell the user that application is alive.
Serial communication mode
A number of various bugs related to support for serial communication mode in Serial and Serial Bridge modules have been fixed. This includes saving the mode into the workspace or log file.
Operating with limited processing resources
During monitoring Device Monitoring Studio uses available disk space as configured in the Data Processing Tab (invoked by Tools » Settings menu command). We have fixed a number of bugs related to Device Monitoring Studio operation under limited settings (like 1% on a single disk and 0% on all others).
"Exporter" data processing modules: Raw Exporter, Text Exporter and Data Recording
A number of bugs have been fixed in exporter modules. CPU and memory usage have been carefully profiled and optimized.

Memory Usage Optimizations

This release also brings improvements to Device Monitoring Studio memory usage strategies. All critical paths have been carefully analyzed and profiled, resulting in memory usage savings of up to 10 times in several places. Application is now much more robust on systems with lower amount of RAM. In addition, when installed on 32-bit operating systems, application is now capable of sustaining much higher data rates during monitoring.

Reduced memory demands now also allow to start "heavier" monitoring sessions - sessions with more data processing modules, complex custom protocols and filter expressions.

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.

Release Changes

New Features

Serial PPP View Visualizer

Device Monitoring Studio version 5.22 introduces new data visualizer – Serial PPP View. It can be used to decode Point-to-Point Protocol packets, as well as a number of packets that can be encapsulated in PPP packets. The current version of the visualizer supports the following protocols:

  1. Novell IPX
  2. OSI Network Layer Control Protocol
  3. DECnet Phase IV Control Protocol
  4. Appletalk Control Protocol
  5. Link Control Protocol
  6. Password Authentication Protocol
  7. Link Quality Report
  8. Challenge Handshake Authentication Protocol
  9. Multilink Protocol
  10. Compression Control Protocol
  11. Extensible Authentication Protocol
  12. NETBIOS Protocol
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.
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.
