Constructor Detail

Maq20Device

public Maq20Device(String nodeName,
                   String[] serialNo)

Constructor.

Parameters:

nodeName - The node name of the MAQ20 system

serialNo - The array of serial numbers of the MAQ20 modules in the system, in device ID order

Maq20Device

public Maq20Device()

Method Detail

configure

protected void configure(org.lsst.ccs.subsystem.monitor.Monitor mon)

Performs configuration.

Overrides:

configure in class org.lsst.ccs.subsystem.monitor.Device

Parameters:

mon - The associated monitor

initialize

protected void initialize()

Performs full initialization.

Specified by:

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

close

protected void close()

Closes the connection.

Specified by:

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

checkChannel

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

Checks a channel's parameters for validity.

Overrides:

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

Parameters:

name - The name of the channel.

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(String name,
                           int id,
                           int hwChan,
                           int type,
                           int subtype)

Initializes a channel. Much of the testing that is often done in checkChannel() has to be done here because the device has to be opened first.

Overrides:

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

Parameters:

name - The channel name

id - The channel ID

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

subtype - The channel subtype returned by checkChannel.

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a channel.

Overrides:

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

Parameters:

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

Returns:

Channel value
