Prologix GPIB-to-Ethernet Python wrapper

Simple wrapper for the Prologix GPIB-to-Ethernet adapter. Also includes a simple device wrapper class.

Currently only supports the CONTROLLER mode of the Prologix GPIB-to-Ethernet adapter.

Requirements

Make sure you can reach/ping the adapter before you start using this library.

Install

Install with pip

pip install git+git://github.com/nelsond/prologix-gpib-ethernet.git

Example usage

Using the adapter directly

from plx_gpib_ethernet import PrologixGPIBEthernet

gpib = PrologixGPIBEthernet('192.168.1.14')

# open connection to Prologix GPIB-to-Ethernet adapter
gpib.connect()

# select gpib device at address 10
gpib.select(10)

# send a query
gpib.query('*IDN?')
# => 'Stanford_Research_Systems,SR760,s/n41456,ver139\n'

# write without reading
gpib.write('*RST')

# close connection
gpib.close()

Using the device wrapper

Also see examples/.

from plx_gpib_ethernet import PrologixGPIBEthernetDevice

class ExampleDevice(PrologixGPIBEthernetDevice):
  def start(self):
    self.write('STRT')

  def get_span(self):
    return float( self.query('SPAN?') )

my_device = ExampleDevice(host='192.168.1.14', address=10)

# open connection
my_device.connect()

# run predefined commands
my_device.idn()
# => 'Stanford_Research_Systems,SR760,s/n41456,ver139\n'
my_device.reset()

# run custom commands
my_device.start()
my_device.get_span() # => 0.191

# close connection
mydevice.close()
