IMVIORS232TriggerSource

The IMVIORS232TriggerSource interface contains methods and properties to configure the MV I/O RS232 Trigger Source  filter.

Methods:

Header file: IMVIORS232TriggerSource.h
Interface definition language file: IMVIORS232TriggerSource.idl
Typelib: MVIORS232TriggerSource
Interface ID: IID_IMVIORS232TriggerSource

Method IMVIORS232TriggerSource::AddPin

Declaration: Function AddPin(iSignal As Long) As Long

Add pin with specified event as MV_RS232TRIGGER_SIGNAL. The event string is also the pins name, e.g. "Ring_On".

Parameter:

iSignal

Trigger event for this pin.

C Prototype:

HRESULT AddPin(LONG iSignal, LONG* value);

Property IMVIORS232TriggerSource::BaudRate

Declaration: Property Get/Put BaudRate As Long

Comport speed as MV_RS232TRIGGER_BAUD_RATE.

C Prototype:

HRESULT put_BaudRate(LONG newVal);
HRESULT get_BaudRate(LONG*pVal);

Property IMVIORS232TriggerSource::ComPort

Declaration: Property Get/Put ComPort As Long

Selected comport.

C Prototype:

HRESULT put_ComPort(LONGnewVal);
HRESULT get_ComPort(LONG*pVal);

Method IMVIORS232TriggerSource::GetIdleLevel

Declaration: Function GetIdleLevel(iPinNumber As Long) As Boolean

Get idle level for this pin. If the idle level is FALSE, the trigger signal will be a TRUE - FALSE sequence and if the idle level is TRUE, the trigger signal will be a FALSE - TRUE sequence.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT GetIdleLevel(LONG iPinNumber, VARIANT_BOOL* value);

Method IMVIORS232TriggerSource::GetPinCount

Declaration: Function GetPinCount As Long

Get the amount of available pins.

C Prototype:

HRESULT GetPinCount(LONG* value);

Method IMVIORS232TriggerSource::GetPinName

Declaration: Sub GetPinName(iPinNumber As Long, pbstrname As String)

Get the pin name for the specified pin.

Parameter:

	iPinNumber	The pin number.
	pbstrname	Receives the name of this pin.

C Prototype:

HRESULT GetPinName(LONG iPinNumber, BSTR pbstrname);

Method IMVIORS232TriggerSource::GetPinSignal

Declaration: Function GetPinSignal(iPinNumber As Long) As Long

Get the event that triggers this pin as MV_RS232TRIGGER_SIGNAL.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT GetPinSignal(LONG iPinNumber, LONG* value);

Method IMVIORS232TriggerSource::IsPinConnected

Declaration: Function IsPinConnected(iPinNumber As Long) As Boolean

Get the connection status of a pin, TRUE if the pin is connected.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT IsPinConnected(LONG iPinNumber, VARIANT_BOOL* value);

Method IMVIORS232TriggerSource::SetIdleLevelHigh

Declaration: Sub SetIdleLevelHigh(iPinNumber As Long)

Set idle level for this pin to TRUE. The trigger sequence for this pin will be FALSE - TRUE.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT SetIdleLevelHigh(LONG iPinNumber);

Method IMVIORS232TriggerSource::SetIdleLevelLow

Declaration: Sub SetIdleLevelLow(iPinNumber As Long)

Set idle level for this pin to FALSE. The trigger sequence for this pin will be TRUE - FALSE.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT SetIdleLevelLow(LONG iPinNumber);

Method IMVIORS232TriggerSource::Trigger

Declaration: Sub Trigger(iPinNumber As Long)

Send trigger signal to this pin.

Parameter:

iPinNumber

The pin number.

C Prototype:

HRESULT Trigger(LONG iPinNumber);
