Nikon D90 to RS232 pin out or links

[lostbit]

I just downloaded backyard nikon version 2.1 I ordered USB to RS232 adapter and a Nikon 8 pin cable.

I am looking for what is needed to connect the two.

Thank You Harry

You may have ordered too quickly. Shoestring Astronomy offers a pre-made shutter control cable solution for the D90. It is compatible with BYN.

Because you are a new poster here, you should know that the shutter control cable is only used to open and close the shutter for long exposures. All other operations need a regular USB cable to be connected between the camera and the PC, in parallel to the shutter control cable.

Thanks Rick, I did read before buying EOSnikon I could just use the USB for short exposures less

than 30 seconds. I have not been able to get that to work. I do plan on making a shuter release

setup in the near future. Ill have to play with that some more. I did find some other resources for

making the cable interface from rs232 to nikon DC2.

Thank You

Harry

Yes, BYN will take non-BULB (Tv) exposures less than 30 seconds. If you cannot get that to work, perhaps you are doing something incorrectly, or some setting in the camera or in BYN is interfering. This group can help.

OK update, I can take a photo only after I do a focus exposure. I can not

get the photo to work in the image tab. Looks like camera busy some times

other times just beeps.  Also the image I do shoot under the focus tab

is not saved to disk, should it be saved?

Camera Nikon D90, basic USB cable Camera set to 1 second manual mode.

What is strange I tried NINA and that takes the shot fine but does not download

to file! Bought BYN but I am still stuck.

There is a BYN setting that controls whether Snap images on Frame & Focus are saved to the hard drive.

Are you testing with a lens? Make sure that the lens is in Manual Focus mode.

You should have worked through these "starter" issues while using the free Trial license. The authors have said that there are no refunds once a purchased license has been issued.

It is possible to shoot a 1 second exposure with either Tv or BULB settings. Be sure NOT use Bulb with the D90 until you have a shutter control cable.

If you have a lens, set it to manual focus.... auto ficus does nto work in the dark anyways.

The default in image tab is BULB, be sure to change that to one of the shutter TV values until you get your DSUSB cable.

As mentioned above, snap images in Frame&Focus are not saved by default.  Go to settings and toggle that option on, and they should save after that.

Hello everyone, I had some of the items to make my own serial connection, did not want

to pay pay for a full solution. I could not get the  demo to work always said the key was invaled.

Good news I build the serial connection and it works fine. I now see saved images, now waiting

for a night no clouds and or rain or snow. 

Thank all for input.

If you only received your Trial license a few days ago, then it should be valid.

Do not try to type the license in manually. Swipe across it with the mouse and copy just the key to the Windows Clipboard with Ctrl-C. Then paste it into the License Validation dialog with Ctrl-V.

I am not worried about the trial version. I knew I would get it to 

work, looks like I am making headway now.

Good day again, back to my eos nikon setup, I had only short RTS trigger over USB serial port.

Windows shows the adapter as com 3, so in BYN I select com 3. Today no voltage on any pins

from the rs232 adapter. Do I need an ascom driver for BYN to use com 3?

Thanks all

Harry

All I know about using shutter control cable with BYE or BYN is in the manual under Configuring your Serial Cable.

Here is a drawing that I found via Internet search:

Hopefully your solution is close to this.
