Important

TWedge version 3 was rewritten from scratch. It is a completely new product with unmatched possibilities, advantages and capabilities. The configuration files of earlier TWedge versions are NOT upward compatible with V3. We are aware that this may cause inconveniences for some customers but we hope that the benefits of V3 outweigh this possible drawback.

Features/Enhancements

• Multiple Devices
  A single TWedge instance is now able to handle multiple devices in parallel. The maximal number of devices is limited by the license kind and the available system resources.
• New Interface Types
  TWedge supports the following interfaces: serial COM ports, TCP client, TCP server, UDP client, UDP server, Bluetooth client, Bluetooth server, USB HID.
• Native Windows System Service
  TWedge provides a standard desktop application which may also be operated as Windows system service. Additional software or extra configuration efforts are not required.
• Integrated Microsoft Excel Support
  Data can be forwarded to Excel worksheets via DDE (dynamic data exchange).
• Ready-to-Use Data Acquisition Templates
  TWedge provides ready-to-use action templates which cover common data collection and data acquisition scenarios.
• Multiple Hotkeys and Timers
  For each device multiple user-defined hotkeys and/or timers are supported.
• Connection Recovery
  Interrupted TCP or Bluetooth connections can be re-established automatically.
• New User Interface
  V3 provides a clearly structured user interface to operate and control multiple devices.
• Password Protected Settings and Controls
  All aspects of the TWedge configuration can be password protected. Privacy and security are enhanced, user errors are reduced.
• Database, File, Excel and Clipboard Access
  TWedge extends standard JavaScript with access-methods for files, ODBC databases and other applications.
• Versatile Scripting
  TWedge generates JavaScript code which encapsulates the data acquisition logic. If required, every aspect of device connectivity or the data acquisition logic can be customized.
• High-Performance JavaScript Engine
  TWedge embeds the well-know V8 JavaScript engine (as used in the Chrome browser).
• Logging and Debugging
  Troubleshooting is easy with the help of JavaScript debugger support and round-robin log files.

Enhancements

• Locking of the Preferences Dialog
  When saving password protected configuration files you can specify whether you want to lock the preferences dialog or not.

• Loading Password Protected Files
  Password protected files with empty scripts failed to load. This is now fixed.

• Connection Retries
  The upper limits for the connection retry count and for the retry delay were raised.
• Additional Information in the Protocol Window
  Now the log shows the success or failure of connection retries.

• Connection Retry Count
  If the retry count was set to zero, TWedge did not connect at all.

• Allow Interface Changes for Password Protected Files
  When saving password protected files you can specify whether you want to lock the interface settings or not.
• New TCP Keep-Alive Setting
  The interface configuration dialog now offers the possibility to adjust the keep-alive timer (in previous versions a lost connections was detected after 2 hours).

• Re-Establish Lost Bluetooth and TCP Connections
  If a Bluetooth or WLAN connection is lost (e.g. out of range), TWedge now correctly tries to reconnect to the respective device.

• Sending Binary Data to a Device
  The function WriteToDevice was extended with a new parameter for specifying the encoding mode. This optional parameter must be set to ENCODING_RAW when sending binary data (0x00-0xff) to a device.

• Binary Data
  New JavaScript variable DATARAW allows full access to the received binary data (byte value 0x00 - 0xFF without any unwanted Unicode conversions).

• Null-Bytes
  Received data with byte value 0x00 at first position was truncated.

• Online Product Activation
  Some systems displayed the activating/licensing dialogs in German instead of English language.

• TCP/IP and Bluetooth Connectivity
  Under some circumstances a new TCP/IP or Bluetooth connection timed out during open (e.g. with slow network speed).
• Null-Byte Awareness
  Some problems were fixed.
• Online Activation
  From now the online activation works only with V2.4 or higher.

• Display Device Data
  TWedge usually displays received device data in the protocol window. This behavior is now adjustable in the Preferences dialog.
• Display Hexadecimal Data
  Instead of displaying the received device data as ASCII characters, the data can be logged in hexadecimal notation. This behavior is now adjustable in the Preferences dialog.
• Online Activation
  TWedge can now be activated online. Manual licensing is still possible if no Internet connectivity is given or if this method is preferred for some other reason.
• RFID Controller Access
  Included are now Javascript samples for reading RFID Tags from EMS RFID Controllers (ABx Fast protocol).

• Null-Byte Awareness
  The new version of TWedge sends and receives data with 0-bytes (NUL - \x00). In previous versions data containing 0-bytes was truncated.
• Input Validation
  The user input in the dialog Data Packets is now validated correctly.

• Native Bluetooth Support
  Version 2.2 is now able to connect to Bluetooth devices directly. What's the advantage? Virtual COM ports are not needed anymore and TWedge reconnects to lost connections automatically! Just select the Bluetooth device in the Interface dialog or enter the address of your Bluetooth device directly (e.g. 00:0c:a7:01:ce:de). The Bluetooth address is usually printed on devices like Bluetooth barcode readers. Another possibility to check out this address is in the Bluetooth Devices section of the Windows Control Panel Control Panel\Hardware and Sound\Bluetooth Devices.
• Automatic Connection Restore
  For Bluetooth^® and TCP/IP connections TWedge restores lost connections (e.g. out of range in the case of Bluetooth) automatically.
• Update Check
  You can check if there is a newer version of TWedge available by clicking Help -> Check for Update...

• JavaScript
  The function MessageBox() now returns correct values and the return values are now defined in the script editor.
• Help-Texts
  The help-texts for some database functions were corrected.

Due to customer feedback the keystroke simulation was improved to offer better support for Remote Desktop Clients (RDP) and Citrix^® XenApp^®:

• SendKeyStrokes Function
  The SendKeyStrokes() function can now be called with an additional parameter to wait for some time after every character was sent. This is useful when the receiving application needs some time to process the keystroke (e.g. sending over a remote desktop connection). If no delay is specified, TWedge uses by default 10 milliseconds.
• Clipboard Functions
  The clipboard functions CopyToClipboard() and GetFromClipboard() were enhanced to retry the operation if the function fails. The number of retries and the time to wait after every retry can be specified by calling the function with 2 additional parameters. Default values are 5 retries with 100 milliseconds delay between retries.

• The format of the TWI files was changed. This ensures that saving TWedge settings also works if special characters (like STX, ETX, EOT, DC1, DC2, ...) are part of the script. TWI files from previous version can be loaded without problems.
  
  
  TWI files are saved always in the new format! Previous versions cannot read the Javascript of V2.1.1 format!

• The new function InputBox() can be used to ask the user for input during runtime (supports optional input validation).
• The clipboard access functions CopyToClipboard() and GetFromClipboard() were introduced. These functions are useful for larger amounts of data, where a simulation of keystrokes is not feasible or too slow.
• The function SendKeyStrokes() now accepts combinations of key constants and modifier keys. The keys have to be separated by a + character (e.g.: "{CTRL+f}" or "{CTRL+SHIFT+h}").
• Toolbar and application icons were redesigned.

• JavaScript support (script-based data-acquisition)
• Direct database access via ODBC
• Direct file access (read/write)
• Hot key support (freely adjustable, script-based hotkey function)
• Timer support (freely adjustable, script-based timer function)
• Bi-directional device communication
• Encrypted and password protected configuration files, end-users are not able to change data acquisition scripts.
• Easy deployment of data acquisition scripts (self-licensed scripts)
• Test-data functionality for script-development

• Beep sound when pressing the Hot Key can be turned on/off in the TWI file now

• Problem with AVM Bluetooth stick was solved.

• Hotkey function for sending data.

• There is no semicolon saved in the translation table (it can't be read from the INI-file).

• A "negative" time out was introduced. This is intended for scales which sends data continuously (until its load stabilizes). This timeout must be at least elapsed, before the last data package will be sent.

• If the "=" sign was used as trigger for the control sequence table, this setting will not be read when the INI-files are reloaded.

• Fixed the HTTP OnClose Event.

• A problem with Act: Window in Win98 was corrected.
