NAME

Lab::Bus::IsoBus - Oxford Instruments IsoBus bus

SYNOPSIS

This is the IsoBus bus class. Typically you create it implicit through instrument creation:

  my $instrument = new Lab::Instrument::IPS({
    BusType => 'IsoBus',
        base_connection => new Lab::Bus::VISA_GPIB({ gpib_board => 0, gpib_address => 24}),
        isobus_addres => 2,
  }

METHODS

connection_new

  $isobus->connection_new({ resource_name => $isobus_address });

Creates a new instrument handle for this bus.

The handle is usually stored in an instrument object and given to connection_read, connection_write etc. to identify and handle the calling instrument:

  $InstrumentHandle = $isobus->connection_new({ resource_name => $isobus_address });
  $result = $isobus->connection_read($self->InstrumentHandle(), { options });

See Lab::Instrument::Read().

connection_write

  $isobus->connection_write( $InstrumentHandle, { command => $command, wait_status => $wait_status } );

Puts in front of the $command-string the isobus_adress, e.g. "@1$command". Passes the modified argument hash to the base_connection. For further information refer to the specific connection class of $base_connection.

connection_read

  $isobus->connection_read( $InstrumentHandle, { command => $command, read_length => $read_length, timeout => $seconds,  brutal => 0/1 } );

Puts in front of the $command-string the isobus_adress, e.g. "@1$command". Passes the modified argument hash to the base_connection. For further information refer to the specific connection class of $base_connection.

connection_clear

  $isobus->connection_clear( $InstrumentHandle );

Clears the specified connection $InstrumentHandle.

connection_query

  $isobus->connection_query( $InstrumentHandle, { command => $command, read_length => $read_length, wait_status => $wait_status, wait_query => $wait_query, brutal => 0/1 } );

Puts in front of the $command-string the isobus_adress, e.g. "@1$command". Passes the modified argument hash to the base_connection. For further information refer to the specific connection class of $base_connection.
