IRdeo - questions and answers
last edit: 17.02.2004 Where can I find the schematic
for IRdeo ?
Where can I find the schematic
for IRdeo Infrared only solution, with learn mode ?
I know that the camera
zoom and exposure can be controlled with control-L. I have a Sony 7000
Digital video camera and don't want to shake it when I need to adjust something
while recording. Even though it has "steady shot" and is on a tripod, I
don't want to shake it because I will put the video on VideoCD, and shake
makes MPEG-1 compression look bad. I don't really need IRdeo for linear
editing- I do digital editing on my computer with "firewire IEEE 1394".
I am trying to find out if IRdeo can control: focus, white balance, black
level, zoom, digital effect, exposure, and any other image features.
From the hardware-interface you can send any command via control-L to
Sony equipment. At the moment the software is not written for this. It
should not be too complicated. If there are more enquiries in this direction,
I might consider to implement it.
I’ve got some problems
with Panasonic Camcorder control system via 5-pin control cable. The sio_demo
recognizes that the Panasonic Camcorder is connected to the IRdeo but none
of the command works except eject which somehow is allocated to play function.
That is true. Everything
should work, however, with the IRdeo32.exe program.
The published source of SIO.PAS
is somehow out of date. The routines for Panasonic control are not included
there. SIO.PAS is under construction, and not republished after every change.
Do the 4052 chips from
different manufacturers have all the same functionality ?
I don't know. At least the
supplied chips from segor electronics are interchangeable.
I have got the following
problem report : The problem was a result of "latch phenomena" which can
occur in some implementation of 4052 chips. I've used Toshiba 4052 chips
that would not work with IRDEO design. I've replaced with Philips an implementation
of 4052 and the problem has been solved immediately.
What do the
boxes with messages mean ? Errors ?
After first run, IRdeo needs
to make some measurements. The boxes inform the user about this. Also the
choice of the relevant COM port is made. If you suspect error messages,
start over and use a fresh copy of the program in an empty subdirectory.
Should the program not work, please provide me with some information :
English and German Q&A
are different.
If you suspect, that your
question has already been asked in German, try the translation service
of Altavista on the
German Q&A page.
Sometimes hard to understand. But better than nothing.
A link to this service is on the
IRdeo UK homepage
The link to the first article
is on the IRdeo homepage : it is included there.
There is no extra schematic
for this solution until now. I am still working on the "perfect" schematic.
Until then take the complete schematic and leave off some parts
as detailed in the link to the pc remote control in the "infrared" navigation bar above.
If you want to speed up things,
do in addition :
Why is the German
translation of Q&A so much longer ?
