DT OpenDataTakerSerialConnection.vi
LabVIEW DataTaker Driver >> DataTaker Low Level Communications >> DT OpenDataTakerSerialConnection.vi
Opens a serial communication session to the dataTaker.
Notes
- Requires that the "DT CloseDataTakerSerialConnection" is called to terminate the connection.
Error Message Generated
- DT LOWLEVEL ERROR: Unable to open serial connection.
Controls and Indicators
|
protocol specifies whether to use standard serial communications, or the DARTS protocol (DT500 only). |
|
port config: serial port configuration options (data bits, stop bits, parity, and flow control are ignored when using DARTS protocol). |
|
parity is the parity used for the connection. The DT 500 uses none, while the DT800 uses none, odd, or even parity. |
|
stop bits specifies the number of stop bits used to indicate the end of a frame. |
|
data bits is the number of bits in the incoming data. |
|
baud rate is the rate of transmission |
|
flow control sets the type of control used by the transfer mechanism. |
|
VISA resource name is the VISA resource used for serial communications (ignore when using DARTS protocol). |
|
DT type shows the type of dataTaker that is connected (DT800 or the DT500 family). |
|
The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
|
The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning. |
|
The code input identifies the error or warning. |
|
The source string describes the origin of the error or warning. |
|
DT serial contains the serial session configuration information. |
|
protocol: specifies whether to use standard serial communications, or the DARTS protocol (DT500 only). |
|
VISA resource name: the VISA resource to use for serial communications (ignore when using DARTS protocol). |
|
DARTS reference Reference to a DT DARTS object. |
|
serial buffer reference Reference to a DT SerialBuffer object. |
|
The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
|
The status boolean is either TRUE (X) for an error, or FALSE (checkmark) for no error or a warning.
|
|
The code input identifies the error or warning.
|
|
The source string describes the origin of the error or warning.
