Questions on Configuring Serial Shutter with GPhoto (DSLR Cameras) in Ekos was created by phattire72

Hello,

I am trying to setup a serial shutter release in Ekos using GPhoto (DSLR Cameras). When I try to connect to the serial cable I get the following error (attached picture):
Cannot Open Camera: Power OK?

In the info for GPhoto (DSLR Cameras) it show the following:

If your camera uses an external shutter release cable, make sure to indicate the port of the shutter release USB cable (usually /dev/ttyUSB0) in the Main Control tab of the GPhoto driver before connecting to the camera.

Additionaly, users may employ DSUSB/DSUSB2 from Shoestring Astronomy in order to control the shutter. Before you connect, the port field must be set to DSUSB.


I verified my Pi is seeing my USB Comm port and it is listed as /dev/ttyUSB0 when I have the terminal list devices.

Does anyone know what I could be doing wrong? I have not added the circuitry for the shutter release yet to the Comm port as I would like to verify GPHOTO sees the Comm port first.

I plan on making the opto-isolated circuit on this website when I get this working: www.beskeen.com/projects/dslr_serial/dslr_serial.shtml

Does Ekos need to see the circuit in order to detect the Comm port?

The error message is that the camera is not getting detected to begin with. Try to install GPhoto2 and test the capture.
sudo apt-get -y install gphoto2

then
gphoto2 --debug --debug-logfile=gphoto.txt --summary

Does it detect it?

It comes up :

*** Error: No Camera found. ***

I do not have a camera connected, only a USB serial port with the opto-isolated serial to shutter release. I have attached the diagram of what I built. My Stellarmate Pi is detecting the USB port from what I can see. I ran ls /dev and I see the follwing:

Bus 001 Device 008: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC
Bus 001 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC

My USB comm port has 2 separate ports and they both populate the list. Is there something in Gphoto2 I need to enable so it looks for the USB serial as a camera?

Hello Jasem,

Does Ekos support the serial shutter if a camera in not connected via USB? I just want to simplify things by using Ekos to Guide, Dither, and Trigger the shutter release with a USB serial cable. I thought from the description for Gphoto2 it would do this, but after some tinkering I see it does not which is why it is not detecting my serial release. My Olympus only has 1 USB port which can either be used for a computer connection or a remote shutter release, so I cannot do both at the same time.

Is there a way to add a stand alone serial shutter control to Ekos without having a camera connected?

Hello Derek,

This is what the "Shutter Release Port" is for in the GPhoto driver. Just find out what port the serial shutter release port is using and put that in. Is it /dev/ttyUSB0 or 1 or something else? what does dmesg say when you insert the cable?
