Constructor Details

RS422VideoIO

public RS422VideoIO(InputStream inputStream,
 OutputStream outputStream,
 long ioDelay)

Parameters:

inputStream - The serialPorts inputstream

outputStream - The serialPorts outputstream

ioDelay - The amount of millisecs to wait between request and responses. RXTX seems to need about 10 Purejavacomm about 100.

Method Details

readResponse

protected void readResponse(byte[] mostRecentCommand,
 VideoCommand videoCommand)
                     throws IOException,
RS422Exception,
InterruptedException

Reads the response to a command from the serial port connected to the VCR.

Throws:

IOException

RS422Exception

InterruptedException

send

sendCommand

protected void sendCommand(byte[] command,
 VideoCommand<?> videoCommand)

Sends a command, in the format of a byte[], to the VCR.

Parameters:

command - The command to send to the VCR

getCommandSubject

public io.reactivex.rxjava3.subjects.Subject<VideoCommand<?>> getCommandSubject()

Specified by:

getCommandSubject in interface VideoIO<RS422State,RS422Error>

getErrorObservable

public io.reactivex.rxjava3.core.Observable<RS422Error> getErrorObservable()

Specified by:
