This visualizer displays all monitored packets, including PnP packets, data transfer packets and serial input/output control code packets. All monitored data can be displayed in one of two schemes - Basic or Complete. In Basic scheme, only general information about a packet is displayed.

In the Complete scheme full packet information, including the binary data attached to the packet is displayed.

This visualizer window consists of two parts. The top part displays monitored packets in a table. For each packet the following information is displayed:

• Ordinal
• Time
• Direction
• Status
• Function

The bottom part is build from several visualizers. Click on any packet in the top part to see it decoded by each visualizer in the bottom part. Click on the tab to switch to the visualizer.

The Playback Tool Window consists of the following elements:

• Log File Path Combo. Displays the folder path where the system searches for log files. Click on the combo to see other variants or press the Browse button to specify another folder. By default, this combo contains the same folder as specified in Tools|Settings, Recording Tab.
• Browse Button. Press to open a Folder Browse dialog to specify the folder where your log files are located.
• Recurse Subdirectories Button. Press to enable recursion when searching for log files.
• Log Tree. Displays all log files (located in selected folder and subfolders), their contents, sorted either by device or by creation date. To view detailed information about a session or a stream, move your mouse over the item to see the description.

To create a log file playback monitoring session, select the stream and click on it. The Session Configuration window appears. Select visualizers and specify the Playback Settings, such as time range and time scale. Once you are ready, press the Start button.

During playback the progress bar appears in the status bar area. You can use this progress bar to track the progress of the playback.

During playback, if there is a long delay in the recorded stream, the Next button appears in the status bar. Press the Next button to skip this delay. In "Stepped" time scale mode, the Next button should be used to step to the next packet.

You can also play back the whole session, stream by stream. To do so, right-click on the session and select "Play Whole Session" option.

This visualizer is capable of displaying the graphical relationship for various monitored data statistics.

It has a large number of counters: Packets Total/Sec, Packets Read/Sec, Packets Written/Sec, Bytes Total/Sec, Bytes Read/Sec, Bytes Written/Sec, Control: Bytes Total/Sec, Control: Bytes Read/Sec, Control: Bytes Written/Sec, Bulk: Bytes Total/Sec, Bulk: Bytes Read/Sec, Bulk: Bytes Written/Sec, Interrupt: Bytes Total/Sec, Interrupt: Bytes Read/Sec, Interrupt: Bytes Written/Sec, Isochronous: Bytes Total/Sec, Isochronous: Bytes Read/Sec, Isochronous: Bytes Written/Sec.

MODBUS View visualizer parses MODBUS protocol requests and responses.

MODBUS View visualizer is compliant with MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1a. There are several different implementations of Modbus Protocol. Different companies implement and document their own specific extensions to Modbus Protocol. Function and command names could vary: for example, Preset Single Register command in one implementation equals to Write Single Register command in the standard.

This visualizer decodes Human Interface Device (HID) specific packets, displaying them in two schemes: HID View and Report View.

In the HID View scheme, the visualizer displays parsed HID Report descriptor requests and brief description of each monitored HID packet.

In the Report View scheme, the most detailed information for each monitored packet is displayed. For each variable the bounded string, usage information from the usage table, logical and physical boundary values as well as the variable value and measurement unit are displayed. Some fields may not be appropriate for some packets.

This visualizer parses and displays commands and data exchanged by the computer and devices conforming to USB Mass Storage Bulk-Only device class and subclass. Specific commands from USB Mass Storage CBI are also supported. There are two levels of display offered by the visualizer: Mass Storage Level and Command Level. The first one parses Mass Storage-specific structures.

Command Level of Mass Storage visualizer parses commands exchanged between the host and device.

Mass Storage standard allows using several command set, including SCSI Primary Command Set, SCSI Reduced Block Set and SCSI Multimedia Command Set. They are usually commonly referred as SCSI Transparent Command Set.

This visualizer decodes Still Image specific packets.

Still Image View visualizer parses and displays commands and data exchanged by the device and host over USB Mass Storage Still Image protocol. The parser supports standard PIMA 15740 commands.

USB Audio visualizer parses packets and configuration descriptors for USB Audio (version 1.0) compliant device. The following subclasses are supported - Audio Control (AC) and Audio Streaming (AS). The first one is used to control and change the state of device. The second one is generally used for data transmitting. Audio class descriptors are displayed in Configuration Descriptor pane.

The following control pipe requests are parsed for the audio class device:

• SET_CUR (0x01)
• GET_CUR (0x81)
• SET_MIN (0x02)
• GET_MIN (0x82)
• SET_MAX (0x03)
• GET_MAX (0x83)
• SET_RES (0x04)
• GET_RES (0x84)
• SET_MEM (0x05)
• GET_MEM (0x85)
• GET_STAT (0xFF)

You can set the filtering for these packets on the Tools|Settings, USB Audio Tab settings page. This page also allows you to specify terminals and feature units to be displayed in converter.

USB Video visualizer parses packets and configuration descriptors for USB Video (version 1.1) compliant device. The following subclasses are supported - Video Control (VC) and Video Streaming (VS). The first one is used to control and change the state of device. The second one is generally used for data transmitting. Video class descriptors are displayed in Configuration Descriptor pane.

You can configure USB Video filtering, displayed terminals and feature units on the Tools|Settings, USB Video Tab settings page.
