The AECntSvc.exe program was created to allow a computer running the
Microsoft Windows NT operating system to keep its internal clock locked
to an external time code (LTC or VITC) reference.  The Adrienne Electronics
Corporation time code reader boards (expansion cards for ISA bus computers)
continuously read the time code into the computer's memory.
The AECntSvc.exe program then compares the external reference time with
the internal time, and makes changes to the computer's internal clock
as needed.  Any of the PC-LTC/VITC/VLTC boards that read LTC and/or VITC
can be used with this program.  The PC-LTC/IOR LTC Reader board is the
least expensive model, and works fine for this application.

This program has been developed as an NT service that has the ability
to start running whenever the operating system is loaded into the computer.
This will allow the computer to always be "time matched" to an external
time code signal reference.  The computer's time will be constantly kept
to within +/- 150milliseconds (max error) of the reference.  The max error
could be kept smaller but the service would end up taking more of the
processor's time to do its job.  This error amounts to no more than 5
time code frames at any given moment.

To use this program and set it up as a Windows NT service, do the following:

1) Follow the instructions to register the WinRT.sys file into the registry.

2) Create a new directory having a name such as "AECtime".  Copy the
   AECntSvc.exe and AEC_NTTC.dll files into the new directory.

3) Open a DOS (console) window and change to the "AECtime" directory.
   Load/install the service by entering the following command line:
                      " AECntSvc -load " <enter>
   This will register the service into the device registry and set it up
   to start automatically each time the computer is turned on (it will
   run in the background like a DOS "TSR" program).  You will need to
   reboot the computer in order for the above changes to take place.

4) You can always stop the service, or change the automatic starting of
   the service to "manual", in the "main" -> "control panel" -> "services"
   Windows NT icon aplet.

5) If you ever need to remove this service from the computer, change to
   the "AECtime" directory, then enter the following command line at the
   DOS window command prompt:
                      " AECntSvc -unload " <enter>
