Time code Clock Jamming on 9x PC WITH *PCI* time code reader cards
Application note:
The following steps 1-4 are general for all uses of the board on a
Windows 9x PC. Step 5 is specific to setting up the software that
will set the PC's clock to match the time code that is read.
When setting the board up to be used as a clock setting (jamming)
source, do the following steps:
1) Install the time code card in the PC (be sure power is off) then
boot the PC and follow the directions in the INSTAL9x directory.
2) Reboot the PC
3) Copy the following two files into directory "C:/AECtime" (or other
directory of your choice)BE SURE THAT THE PATH TO THIS DIRECTORY DOES NOT
CONTAIN ANY LONG (GREATER THAN 8 CHARACTERS) FILE/DIRECTORY NAMES.
a) 9xPciClk.exe (in Instal9x directory)
b) AecPciPoll.exe (in PCI_noDLL subdirectory)
c) There is also a sample .bat file with the 9xPciClk.exe
that you may want to copy so that you can edit it as
you desire. See below for additional command line argument
information.
All of these files are located on the PCI board diskette in various
directories.
4) Run C:/AECtime/AecPciPoll.exe and see if this program runs.
This small program provides some very good indications as to the
performance of the a) driver and b) the time code reader board
and the reading performance of the board (if time code is hooked
up).
5) Now try running the 9xPciClk.exe program from a console window.
See the additional text below for more information on the
required command line arguments.

Clock setting service application INFORMATION & INSTRUCTIONS
**** NEW VERSION for PCI time code reader cards ONLY *****
The 9xPciClk.exe file was created to allow a computer running the Windows9x
operating system to keep its internal clock locked to an external reference
time code time reference. The Adrienne Electronics Corporation PCI-LTC/RDR and
other PCI-xTC/??? models that read time code (expansion cards for the PCI bus)
present the time to the computer as it is read. This program instructs the
computer to change the computer's local/system time to match the time code time
(with a possible offset).
This program has been developed to run as a '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 computers time will be constantly kept to within "the
command line parameter value that you set" (+/- 50 to 250 mSec (max error)).
Note: Windows 9x does NOT support 'service' applications, WindowsNT does. This
program is designed to run "like" a service.
To use this program and set it up as a service, do the following:
1) Open an MS-DOS (console) window and get the "c:\" prompt to the new
directory. (ie. "c:\AECtime" ). Load/install the service by running
the program with the following command line (with options).
9xtPciClk -load X nnn fff kkk <enter>
to load the AEC 9x Pci Clock Set service where
X = S or L, (set the SYSTEM or LOCAL time (CAP sensitive)
nnn = 50 to 250 (user defined, maximum allowed
time code vs. clock time mismatch before
resetting the PC's clock. (milliseconds))
fff = Offset from 0 to 1439 minutes.
(00:00:00:00 to 23:59:00:00. The PC's clock will
be set to match the time code PLUS (+) the Offset)
This parameter allows for "time zone" offsets to
be handled if the time code that is being read is
not the same as the Local or System time.
kkk = 50 to 60000 (50mS default,60000 mS (1min) max)
(Allows for the times to be checked and compared
less often. Decreases the amount of CPU time used
the larger the number. Note that this service uses
very little time anyway.
For Example:
'9xPciClk -load L 100 0 1200 <enter>'
will set the LOCAL time to within 100ms of time code with
0 minute offset, and will re-check for clock drift every
1.2 seconds.
### SEE/edit THE ClkSampl9x.bat file for easy command line entry ###
This will register the service into the device registry and set it up to
start automaticly each time the computer is turned on (and it will run in
the background like a "TSR" program). You will need to reboot the computer
in order for the above changes to take place.
2) If you ever need to remove (stop) the service from the computer, enter the
following command line at the MS-DOS promt (at the new directory) ...
" 9xPciClk -unload " <enter>
END!
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
