Constructor Detail

DL34970Device

public DL34970Device(String connType,
                     String devcId,
                     int baudRate)

Constructor.

Parameters:

connType - The device type (FTDI or serial)

devcId - The device parameter (serial no. or device name)

baudRate - The baud rate (0 for default)

DL34970Device

public DL34970Device()

Method Detail

initDevice

protected void initDevice()

Performs configuration.

Overrides:

initDevice in class org.lsst.ccs.monitor.Device

initialize

protected void initialize()

Performs full initialization.

Specified by:

initialize in class org.lsst.ccs.monitor.Device

close

protected void close()

Closes the connection.

Specified by:

close in class org.lsst.ccs.monitor.Device

checkChannel

protected int[] checkChannel(String name,
                             int hwChan,
                             String type,
                             String subtype)
                      throws Exception

Checks a channel's parameters for validity. This is called before the device has been initialized.

Overrides:

checkChannel in class org.lsst.ccs.monitor.Device

Parameters:

name - The channel name

hwChan - The hardware channel number

type - The channel type string

subtype - The channel subtype string

Returns:

A two-element array containing the encoded type [0] and subtype [1] values.

Throws:

Exception - if any errors found in the parameters.

initChannel

protected void initChannel(int chan,
                           int type,
                           int subtype)

Initializes a channel.

Overrides:

initChannel in class org.lsst.ccs.monitor.Device

Parameters:

chan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

subtype - The encoded channel subtype returned by checkChannel.

readChannelGroup

protected void readChannelGroup()

Reads grouped channels.

Overrides:

readChannelGroup in class org.lsst.ccs.monitor.Device

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a channel. The channels have been read in ascending channel number order (this is a feature of the data logger), so the map is used to locate where in the data array a particular channel is located.

Overrides:

readChannel in class org.lsst.ccs.monitor.Device

Parameters:

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

Returns:

The value read from the channel
