Looking for advanced discrete codes for the video input L1 & video input F1, for a JVC 3500 SVHS VCR.

I have the same VCR. Pressing "0" for channel number effectively sets the VCR to L1 input. It takes the VCR a few seconds, but it works. I have yet to find a disrete advanced code for F1, but simply hitting "0" then channel down gets you there discretely. I haven't tried searching all the possible advanced codes yet. There are several missing numbers on the list I quelled from Starbase314 and ONE4ALL together. I'm still looking. I'll let you know if I find one.

Dave

Et tu, David B.? I'm beginning to wonder if I'm
the only one who's actually done an exhastive
search for advanced codes. :)

-=Ingenious=-

I finished my 000 to 255 search. If you're using device code 0067 for JVC VCR's, these codes should work...

070 - Discrete L1 selection
079 - Discrete F1 selection
177 - VCR PLUS beginning
180 - Eject
122 or 250 - audio mode toggle discrete
100 - shifts picture (or perhaps just text) on screen


I didn't find a code that would discretely take you back to tuner on the channel you jumped from, but if the original remote has a "previous channel" function a.k.a. jump or back or review then that should do it. My original remote is packed in a box somewhere yet to be found.

There are a slew of other codes that do something useful, and a few that do strange and possibly dangerous things to the VCR. I got mine into a display mode that refused to show the time and had to unplug/reset it to get it working again.

Hope these few help.

Dave

David B.,

I have a Sony VCR I did an advanced code search
on, and I found a similar code to the one you
mentioned. It makes the VCR display the number
30106 on the display instead of the counter or
the time. It don't see how it could be
considered dangerous, however. I believe is it a
diagnostic code. I've actually seen that number
come up once, and only once, before, and that was
when a piece of a VHS tape broke off inside the
machine, and jammed the mechanism. The VCR did
it's best to operate normally, but upon
discovering it was stuck, it gave up and
displayed the number 30106, which I assumed was
some sort of error message. Now, with my Cinema
7, I can make it display that number on command,
not that that is a particularly desirable
feature, but it's interesting nonetheless.

That's probably my favorite thing about this
remote: the WEIRD stuff you can do with it. Just
controlling all the equipment is great, but for
me the real fun is in finding ways to do things
you CAN'T do with the original remote.

That's why this kind of remote is better than a
pure learner. They can only duplicate; This can
originate.

David,

Thanks for the quick update, I will give the codes a try tonite.

Do you know whether there has an advanced discrete code to display the TIME on the VCR display, rather than using the advanced code 533 Display, and cycling thru each of the display options until the time is displayed ??? I like to use the VCR Time display as a device that I can quickly glance at to determine what the actual time is.

Wonderful device, however, I need more memory !!!

Mike,

No, I did not find one that will discretely make the VCR show the time. Of course, mine automatically shows the time once it's turned OFF. and I DO have a discrete OFF code for it (247). BTW, ON is 248.

Ingenious,

My VCR would go into a display mode E:--:__ with code 233. I assume that E is for Error, and if there had been an error in the VCR the E: would have been followed by some numbers. Code 233 toggles this display on and off.

There was some other code I sent, and I wasn't paying enough attention when I did it, that froze the display with 23:12 or something similar. Nothing I could do would get this off the display, except unplugging the VCR.

The few fun and odd things I discovered include 3 sets of channel up and down codes, a code that turns on and OFF a red REC LINK light on the VCR face (which I have no idea what means), discrete channel numbers 10 thru 14, and the above mentioned picture shift.

I did my search with no tape in the VCR, so there are surely some additional functions to be found for the recording and playing conditions of the VCR. The list I have already documents all of the common and most of the rare transport functions.

The great delight in discovering hidden functions is when you realize that internally your device probably has most of the features of it's more expensive brothers, and it's only the "dumbed down" remote they included with it that prevents you from using these features. On of the ways sony differentiates it's camcorder models is that their cheapest doesn't include a remote control. What they don't tell you is that it will WORK with one. I found this out by trying a Pronto CCF with codes for sony camcorders on my cheap sony that came with no remote. That in itself was worth $50 of the Pronto's price, since Sony wanted an extra $50 for the model with the remote.

As for doing the exhaustive 000-255 code search... I've done it for every device I own. Sometimes it's very depressing to find NO additional functions. The older the device, the less likely there are undiscovered features it seems. Most of the time it is empowering! All of the time it is worth the trouble, since just knowing means you can stop wondering.

Dave

David do you happen to remember what the code was for turning the record link on?

PJ

PJ,

Code 228 is for REC Link. Again, this is for device code 0067. Can you tell me what REC Link is for?

Dave

David,
I think the REC Link is a way to record from cable or satellite in some way. Its mentioned in the manual by the way. The vcr will start to record as soon a signal becomes active on the L (rear) inputs (and the vcr is off or on timer I think). I don't whether they mean any AC signal, a DC level or a correct composite signal with sync in the right place. It will be an unused function unless someone here can think can think of an interesting use.

David B.,

>The few fun and odd things I discovered include
>3 sets of channel up and down codes...

I suggest you investigate these three sets
further. I have a similar situation with my Sony
VCR, only with 2 sets, and I knew in advance I
would find two sets. Why? Because one is the
channel up and down codes, and the other is the
shuttle right and shuttle left codes. Now, there
IS NO shuttle on the original remote, but there
IS on the console. I used 994 to replace the
channel up and down buttons on the Cinema 7 with
the shuttle right and left codes, which enables
me to change channels as before, but also use the
same buttons to access slow motion, reverse play,
reverse slow motion and such, all using the
channel up and down buttons of the Cinema 7. I
recommend it as a very handy and efficient use of
buttons.

>...a code that turns on and OFF a red REC LINK
>light on the VCR face (which I have no idea what

I did a quick search of usenet, and I get the
impression that rec link is a feature that you
enable with the vcr off, and set to one of the
inputs. I think the VCR is then supposed to turn
on and start recording whenever it detects a
video signal on that input, and turn off again
when the signal goes away. That would be my
guess, based on some extremely sketchy reports.
Perhaps someone who knows more on the subject
could confirm or correct this.

Well that's just weird. :)

Yes, indeed. It's the advanced codes, and the
weird things that can be done with them, that
really make these remotes worth the money. So
much so, in my not-so-humble opinion, that
they're worth the money even if you're completely
satisfied with your current remotes.

It's more than a universal remote; it's a
consumer electronics hacking tool. :)

I wonder if similar situations exist among Sony's
portable CD players. I know some of the higher
end models have remotes, but most do not,
including the one that I have. Maybe later I'll
see if I can get it to respond to the Cinema 7,
although I've never seen anything on it that
looked like a remote sensor.

I think it's because the older the device, the
more likely it was designed from the ground up,
whereas the newer ones tend to be made with
higher levels of integration, using more
standardized designs. You may find functions
that are supported by everything but the original
remote, or you may find functions that are
supported by the programming, but which can't
work without some absent sensor or component. Is
the sensor required for "rec link" present in
your VCR? You'll have to check and see. It's a
crapshoot. :)

David,

I tried the advanced discrete codes for F1/L1 input selection, works just as you advertise.

Thanks a bunch,I personally don't have the patience myself to try all the undocumented codes !!!

Now, if I could only get a memory upgrade, I am in the process of streamlining my advanced codes and macro programming to fit the 180 memory unit limitation.

Any idea whether the 8800/9800 has a larger memory size than the 6800/7800 to work with ???

Mike K.

Mike,

I'm glad the codes worked for you. I'd love a memory upgrade too, but until then I've already optimized my customization as best I can.

I have no idea what limits the 8800/9800 remotes have. If someone wants to send me one, I'll gladly figure them out. I have LOTS of free time.

Dave

David thanks for the code for the record link. Ingenious is right it allows you to put the vcr in a ready to record mode and once a signal is detected through the line 1 inputs it begins to record until the signal is no longer there. This works great in conjunction with a timer menu system on a satellite IRD. On my JVC S3600 you have to manually push the record link button. It will be neat if I can now put it on with the remote.

thanks again
