Constructor Detail

SimA1000Device

public SimA1000Device()

Method Detail

initDevice

protected void initDevice()

Performs configuration.

Overrides:

initDevice in class A1000Device

initialize

protected void initialize()

Performs full initialization.

Overrides:

initialize in class A1000Device

close

protected void close()

Closes the connection.

Overrides:

close in class A1000Device

setFrequency

public void setFrequency(double freq)

Sets the frequency.

Overrides:

setFrequency in class A1000Device

Parameters:

freq - The value to set

getFrequency

public double getFrequency()

Gets the frequency.

Overrides:

getFrequency in class A1000Device

Returns:

The set frequency, or NaN if device is offline

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 A1000Device

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.

readChannel

protected double readChannel(int hwChan,
                             int type)

Reads a channel.

Overrides:

readChannel in class A1000Device

Parameters:

hwChan - The hardware channel number.

type - The encoded channel type returned by checkChannel.

Returns:

The value read from the channel
