I just purchased a Canon T6i/750D and was looking at how to connect it to APT for a programed eclipse sequence. Most of the documents I am reading indicate using a serial cable to control the shutter but my searches for one are coming up blank. Does anyone know where I can find one?

Hello, have you tried to control the camera with the USB cable provided with the camera?

The serial cable is needed to enable you to shoot 1-2 images per second via APT vice the 1 per every 5seconds that the USB cable allows. I think I may have just found one from Hap Griffin.

I wasn't aware of that subtle detail! I wish you good luck with your project!

Have you tried setting up a plan in APT to do this as im sure its possible.
ie 1/50th of seconds no pause

Yep I tried that and APT automatically puts in 5sec even if the pause is set to zero. They indicate it is a limitation of communicating with the camera via USB. I checked the APT forum and someone had already asked the question about setting up continuous shooting with no delay and APT responded that they have a "Extreme EOS shooting" mode that does allows for 1-2frames/second but it requires the use of both the USB cable and a serial cable.

Just tried it with my 750d
Seems funny you can do a 300 second exposure but not a 1/2 second exposure one after the other , they need to sort that out i think.

I tried to replace USB standard cable for a longer one (2-3 meters instead standard 6 feets), but it does not work, no signal. Do I need a shielded one with compensators?

This might be helpful.  It is from the Edlipse Orchestrator website.   The links discuss how to make a serial cable.

Shutter Cables: (Pro only)
  • Supports virtually all RS-232 serial port shutter cables using the RTS or DTR signal. Nikon IR cables supported. Powered cables supported. Inverted (active low) cables supported. For computers without a serial port, the Shoestring DSUSB is supported, or a USB to serial adapter can be used.[/*]
  • A common question is why using an RS-232 serial port shutter cable is faster than USB 2.0 for taking photos. The irony of a 1960s-era interface outperforming a 480 megabit one is not lost on us. No, it's not an artificial limitation, it's primarily due to the fact that when triggering an exposure via USB, the camera does not allow buffering. That limits you to the speed at which each exposure can be flushed out to the internal memory card. When using the shutter cable, images can be buffered in the camera's RAM before being written, allowing bursts of exposures at or near the maximum speed of the camera.[/*]

Try using backyard EOS. The only delay I get is the camera writing to the SD Card.  You can try taking a movie with it as well. Pretty high frame rate.

I just bought the Canon serial cable from Hap Griffin but have decided to use BYE since I know it well and I do not want to learn a new program.  I would be happy send it to anyone for a discounted price ($28.00).  I have it on Ebay at -

I replaced my cable with Belkin USB-mini 6 feets, works just perfect a bit expensive (US $ 25), but worths any penny  ;)
