NAME

Lab::Connection::VISA_RS232 - RS232-type connection class which uses Lab::Bus::VISA and thus NI VISA (Lab::VISA) as a backend.

SYNOPSIS

This class is not called directly. To make a RS232 suppporting instrument use Lab::Connection::VISA_RS232, set the connection_type parameter accordingly:

 $instrument = new BlaDeviceType(
    connection_type => 'VISA_RS232',
    port => 'ASRL1',
 )

DESCRIPTION

Lab::Connection::VISA_RS232 provides a RS232-type connection with Lab::Bus::VISA using NI VISA (Lab::VISA) as backend.

It inherits from Lab::Connection::RS232 and subsequently from Lab::Connection.

The main feature is to set upon initialization all the RS232 libe parameters baud_rate ...

CONSTRUCTOR

new

 my $connection = new Lab::Connection::VISA_RS232(
    port => 'ASRL1',
    baud_rate => 9600,
 )

METHODS

This just falls back on the methods inherited from Lab::Connection.

config

Provides unified access to the fields in initial @_ to all the child classes. E.g.

 $GPIB_Address=$instrument->Config(gpib_address);

Without arguments, returns a reference to the complete $self->Config aka @_ of the constructor.

 $Config = $connection->Config();
 $GPIB_Address = $connection->Config()->{'gpib_address'};
 

CAVEATS/BUGS

Probably few. Mostly because there's not a lot to be done here. Please report.
