Two camera question again

[whwang]

Hi,

 

Based on another earlier thread, it seems not possible to launch two BYE instances to control two cameras on the same mount to dither.  Now, my need is slightly simpler than this, and I would like to know whether this is possible.

 

The situation is, I have two cameras (One Nikon D800, one Canon 5D2) on the same mount, and I would like to dither.  However, only one of the cameras needs BYE or BYN control.  Let's say I will use BYE to control the 5D2, to focus and frame, and to image and dither.  I don't need any other imaging/focusing function on D800.  All I need is a Bulb signal that is synchronized between the two cameras, so the dithering on 5D2 will not destroy the exposure on D800.  Is there any setup that can do this?  For example, if I use DSUSB between 5D2 and BYE for shutter control, can the same shutter signal somehow be wired to D800 too?

 

Cheers,

Yes that would work. 

 

EDIT: But you need to split your DSUSB so you get 1 camera connection and one computer usb connection.

 

1) Start BYE as you normally would

2) Go to Settings -> Advance Settings and enable "FORCE SERIAL CABLE"

3) Select DSUSB in cable select (Capture Plan Center)

 

4) Start BYN and connect your D800.  This is optional but it is practical if you want your NIKON images download to the computer

 

5) Using your BYE instance (from step 1) start your capture plan.

 

Both cameras should fire at the same time and you'll be able to dither using your BYE instance.

 

Hope this help.

Thank you Guylain.  That would solve my situation.

 

Just to make sure, what you said is that BYE can fire shutter signal to two cameras, one

via USB and one via DSUSB, right?

Not directly.  You need to hack/split your cable so it has 2 camera connection end, one for each camera.

 

I have never seen someone do this with a DSUSB but I've seen a few users using a straight serial cable and spiting it to add a second camera connector/plug.

 

Does make any sense?

 

Hope this help,

Hi,

 

Now I get a DSUSB controller and a Y splitter for the controller to connect to

both a Canon 5D2 and a Nikon D800.  The BYE is controlling the Canon, of course,

and is also the one that fires the shutter signal and PHD dither signal.  I did not 

open BYN at this moment.

 

However, here I am facing a new difficulty.  BYE cannot trigger D800's shutter this way.

Using DSUSBCheck, I found that to control D800's shutter, it requires the assert

and dessert wakeup signals too.  It seems BYE doesn't do this.  (Perhaps BYN does,

since people report that BYN works well with D800+DSUSB.)

 

Is it possible to let BYE also trigger the wakeup signal through DSUSB?  Doug

at Shoestring told me that this should not affect Canon cameras.

 

(I know that it may work the other way: using BYN to trigger shutter and PHD

dither.  However, I am having some difficulty connecting to my D800 with 

BYN beta02e.  I will report this on the BYN forum later.)

Hi Wei-Hao,

 

Try BYE 3.1 RC04, it does have the assert/deassert commands.

 

In BYN, you probably need to enable "Force Serial Cable" in advance settings to tell BYE to use the DSUSB cable for BULB.

 

Keep me posted

Hi Guylain,

 

It works perfectly with 3.1RC4.

Now I can synchronize the dither and shutters of my two cameras.

This is wonderful.
