If you are going to monitor device that is not currently connected, you can select "Next Connected Device" entry to monitor this device activity after it is connected to the system.

You can start monitoring session for each connected Serial Device, just click on the device and select the way you want to display monitoring data in session configuration window. You'll be able to add up to 10 visualizers for each monitored Serial Device.

This tool window displays the information for the selected serial device. You can scroll the contents of the window to view the whole information if it is larger than window. Use the keyboard or mouse to select the text in the window and select the Edit|Copy command to copy the selected text into the Clipboard.

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
• Function
• Direction
• Status
• Data
• Data (Characters)

The bottom part is build from the following visualizers: Request View and MODBUS View. 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.

This visualizer contains two panes. The top pane displays that was read from the device, and the bottom pane displays the data written to the device.

This visualizer works as the text console, showing all the received data as ASCII characters.

This visualizer displays the state of the serial/modem control lines. The following lines states are displayed:

• RTS Request to Send line indicator
• CTS Clear to Send line indicator
• DSR Data Send Ready line indicator
• DCD Data Carrier Detect line indicator
• DTR Data Terminal Ready line indicator

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 Monitoring Session type represents the virtual bridge between two distinct serial devices connected to two computer serial ports. The devices must be connected using the so-called null-modem cable.

Serial Bridge Configuration Window

This window allows you to configure the bridging between two computer serial ports. It consists of two groups, called New Bridge and Existing Bridges.

Existing Bridges group lists all bridges you created since you started the Device Monitoring Studio. Each bridge may be in one of two states - running and stopped. When you create a new bridge it is in Stopped state by default.

Click on the bridge in the Existing Bridges group to open the Session Configuration window. After you click the Start button in the Session Configuration window, the bridge enters into the running state.
