devcId - The device parameter (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(org.lsst.ccs.monitor.Channel ch)
                      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:

ch - The Channel to check

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(org.lsst.ccs.monitor.Channel ch)

Initializes a channel.

Overrides:

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

Parameters:

ch - The Channel to initialize

getGroupForChannel

protected String getGroupForChannel(org.lsst.ccs.monitor.Channel ch)

Gets the group for a channel.

Overrides:

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

Parameters:

ch - The channel

Returns:

The group name, or null if not in a group

readChannelGroup

protected void readChannelGroup(String group)

Reads Channels for the provided group.

Overrides:

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

Parameters:

group - The group to read.

readChannel

protected double readChannel(org.lsst.ccs.monitor.Channel ch)

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:

ch - The Channel to read.

Returns:

The value read from the channel
