Appendix G: The automated test equipment (ATE) interface
Both the OUI and the LRCP have two types of WCF interfaces to allow control
from a user application. Both types are provided to achieve full functionality and
compatibility with simple interfaces such as MATLAB and via a client application
program.
The LRCP ATE interface
The Automated Test Equipment (ATE) interface exposes the LRCP functionality
through a Windows Communication Foundation (WCF) service. As the LRCP is
used with all OM4000 instruments, its interface exposes more commands than
those used by the OM4x06 CLSA.
Basic/Advanced WCF
Service Interface for the
LRCP
The WCF services (basic and advanced) are available on port 9000 in the machine
that is running the LRCP. The service (basic and advanced) interface was
developed for incorporation into an ATE client application that can be developed
in your choice of .NET language, typically C# or VB.NET. Both services expose
most of the functionality that is available through the LRCP’s user interface.
The basic service, implemented using a wsBasicHTTPBinding, exposes the
same subset of commands as the advanced service. It was implemented using
a simpler binding for compatibility with applications like MATLAB (See
page 167,
ATE functionality in MATLAB .) or Labview that only support the
wsBasicHTTPBinding. The basic service is referenced at the following URL:
http://localhost:9000/LaserReceiverControlPanel/Laser_ReceiverServiceBasic/
The advanced service, implemented using a wsHTTPBinding, (and which is not
available in MATLAB) was developed for use with an ATE client application
(See page 169,
Building an OM4006 ATE client in VB.NET .) and uses events
to provide a time-ef fi cient interface.
The advanced service is referenced at the following URL:
http://localhost:9000/LaserReceiverControlPanel/Laser_ReceiverService/
NOTE. For safety reasons, neither the basic or advanced services support the
activation of a laser; this must be done on the user interface.
