Bulb mode does not release shutter

[jpb1978]

Backyard EOS version 3.1.17, Canon 400d xti.  USB attached.  No serial port on camera.  Works fine when when a specific shutter time is chosen in capture plan but if bulb is selected the shutter will not release.  If I manually trip the shutter while the timer is spinning then it works.  Any suggestions?  I have considered getting a timed remote bulb but in addition to the added expense I would have to sit by the camera and perform each shutter release.

Thanks,

Joe

Your XTi is a DIGIC II camera. It requires a second cable for BULB shutter control. This is outlined in the Supported Cameras table on this web site.

Shoestring Astronomy makes a DSUSB cable that is compatible with BYE for this purpose.

The 400D is an old camera.... it is in fact the last model Canon made that requires a serial cable for bulb. 

You need a serial cable.

Thanks for the replies, I am thinking I should get a newer camera.

If you look at Used Canon DSLRs, avoid the T4i and the M series.  As always, check for compatibility and supported features on the Supported Cameras page.

Thanks, I am currently looking at the 77D.
