Configuring DCOM Access to Your Unit
Configuring DCOM Access to Your Unit
DCOM technology allows to control devices and optical instruments via
Ethernet. The EXFO IcSCPIAccess Class component provided with your
unit acts as a communication link between a client application and EXFO’s
Instrument Control. For more information, refer to the EXFO Remote
Control Demo available in EXFO Apps, at
http://www.exfo.com/software/exfo-apps/exfo-remote-control-demo .
DCOM ensures communication between the client application and
Instrument Control via your local network. Since each network has its own
configuration, you need to be familiar with network security, users, groups,
domain management, etc. Basic programming skills are also required to
work with DCOM. For more information, you can refer to the Microsoft
MSDN Help feature, which provides exhaustive technical documentation
on all DCOM issues.
The example presented in the following pages illustrates how to make the
EXFO IcSCPIAccess Class component available to all users of a local
network under Windows 8.1 Pro. The example provided below is for
guidance only; it may not work properly with all networks and interfaces
may slightly differ depending on the operating system used.
To enable DCOM access to your unit, you must:

set the general security parameters

customize the specific security parameters

register callback events.
