TConnector: DAQ Software Data Sheet | | | | | | TConnector has a wide collection of implemented interfaces (COM, LPT, TCP, Bluetooth, File I/O, ...), which are all accessible through a unified API. The easy to handle TCP/IP support simplifies intranet applications considerably. | | |
DAQ Software
| | Platforms
- ActiveX® Control (Microsoft® ActiveX compliant, ATL based)
- Win32 API
- Operating systems: Microsoft® Windows® 98 / ME / NT 3.51 / NT 4.0 / 2000 / XP / 2003 / Vista / Server 2008 / Windows 7
- Not supported: Microsoft Windows 95
| |
InterfacesAll interfaces are available within one ActiveX Control and through one unified API! | | Supported Interfaces| Serial Port / RS232 | Serial Port (e. g. COM 1-4): reading and writing data | | Parallel Port / Centronics | Parallel Port (e.g. LPT 1-2): writing data | | Bluetooth | Bluetooth address (like 1B:F3:E1:10:01:21): reading and writing data; connection in client mode | | TCP/IP | TCP/IP (host address + port adjustable): reading and writing data; connection in client mode | | File I/O | File read and write | | NULL | NULL Device |
| |
Operation Modes | | Communication Modes
- Synchronous (read/write)
- Asynchronous (OnData event for reading)
- Software wedge (SendKeyStrokes property)

Properties | | DAQ Software Object Properties| IOType | Interface Type (None, NULL, FILE, COM, LPT, TCP, Bluetooth) | | Device | Specifies the exact port to connect with; used with communication types File, COM, LPT | | Baud, Data, Stop, Parity | RS232 settings; used with communication type COM | XOn XOff, DTRDSR, RTSCTS,
DTRDefault, RTSDefault | Handshaking; used with communication type COM | | Host / Service | TCP/IP host/service (address & port); used with communication type TCP | | NoOfBytes | Maximum of bytes to receive before an OnData event will be fired. | | Timeout | Timeout in milliseconds. After the timeout period an OnData event is fired even if less than NoOfBytes bytes were received. Valid if property Timout_Infinite isn't set. | | Timeout_Infinite | Timeout infinite (true/false); determines if a timeout period is set by the value of Timeout_Infinite or there is no timeout (infinite) | | Prefix | Defines a string that is placed in front of all other data characters sent by the OnData event. It can contain arbitrary ASCII characters and predefined escape sequences. | | Postfix | Defines a string that is appended to a data package sent by the OnData event. It can contain arbitrary ASCII characters and predefined escape sequences. | | UseDelimiter | Use delimiter character (true/false), if true the OnData event will be fired immediately when receiving the delimiter. | | Delimiter | ASCII code of the delimiter character; e. g. Linefeed = 10 | | IncludeDelimiter | Delimiter character is part of the data or is to be removed. | | SendKeyStrokes | If set, the incoming data is translated into corresponding keystrokes. These characters are simulated as if they are entered on the keyboard (software wedge mode). |

MethodsEasy integration into Microsoft Visual Basic, Microsoft Internet Explorer, Microsoft Visual C / C++, Delphi, NET, Microsoft Office (Microsoft VBA, Microsoft Excel, Microsoft Access, Microsoft Word...), ASP, VBscript, Javascript, and many more! | | DAQ Software Object Methods, Events| Open () | Opens a connection to the device specified by IOType & Device. | | Close () | Closes connection. | | Read (...) | Reads data with maximum length of nBytes within the period defined by timeout. | | GetNoOfBytesRead () | Returns the number of bytes received during the last Read method. | | ClearBuffer () | Deletes all data from the input buffer. | | Write (...) | Writes data with length of nBytes within the period defined by Timeout. | | StartListen () | Starts asynchronous mode: OnData events are fired when data is received by the specified interface (IOType & Device). | | StopListen () | Stops asynchronous mode. | | SetStates (...) | Set status of interface status line(s). | | AboutBox () | Displays about dialog. | | EscapeZeroBytes (...) | Represent Zero Bytes (binary value = 0x00) as "\0" in the input/output data stream. Avoids truncation of strings by Zero Bytes in COM wrappers (such as used by Visual Basic). | | LicenseMe (...) | Licensing by program code. After applying a valid license key the demo version is turned into a full version. The insertion of "Demo" into the data stream will be disabled. | | Licensing () | Opens the license dialog for manual licensing. After entering a valid license key the demo version is turned into a full version. | | OnData (...) | Each time when data is received an OnData event is thrown (in asynchronous mode). The data read from the device is returned within the Data argument. | | OnStatusChange (...) | Each time when a status line changes its state, this event will be fired (in asynchronous mode). The changes are passed as array in the States argument. | | OnClose () | This event occurs when the server closes the connection (only available for IOType "TCP"). | | OnError () | This event will be fired when an error occurs (only available during asynchronous mode). | | TranslateErrorNo (...) | Translates the error number given by the OnError event to the corresponding error text. | | SetDebugLevel (...) | Enables tracing of TConnector's internal activities into a log-file. | | GetStates () | Returns an array of actually set states. | | SetSingleState (...) | Like SetStates(), but only to set a single state. | | EmulateKeys (...) | Translates an input string into virtual key strokes and puts them into the keyboard events message queue. | | UseCodePage (...) | Adjusts Codepage to be used for Unicode-MultiByte string conversion. |

HighlightsRemote Data Acquisition OnData Event Contact us for customizing | | Special Features
- In connection with TEC-IT's COM2TCP software you can build up a remote network for serial data acquisition with only a few steps.
- Handling of incoming data is made easy by the asynchronous mode. An OnData event can be generated automatically when data is received by the specified interface. In addition to this event you can simulate key strokes of the incoming data (wedge mode).
- Removal of delimiter characters adjustable (e. g. CR/LF).
- Custom specific extensions and/or adaptation to custom needs available on request.
