NAME

Lab::Connection::VISA_RS232 - RS232-type connection which uses NI VISA (Lab::VISA) as backend

VERSION

version 3.631

SYNOPSIS

This RS232 Connection class for Lab::Bus::VISA implements a RS232-Standard connection on top of VISA (translates RS232 settings to VISA attributes, mostly).

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.
