MMRDevice

public MMRDevice()

Method Detail

configure

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

Configures the device parameters.

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. This is a no-op

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.

readChannel

                             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

setPowered
