I am trying to use my Nikon D5100 with Asiair Plus but running into some issues with exposure. I understand that Nikon does need two connections - 1. USB connection for data transfer, 2. Shutter release cable ( connected to "DSLR" port on Asiair) for exposure over 30secs ( also known as support for bulb mode).
My problem is when the shutter release cable is enabled, I cannot trigger the image, it comes back with " exposure failed, check shutter release cable" and if I remove the cable, I can trigger the image capture but limited to 30sec exposure only. Wondering if this is a problem with my Shutter release cable?
Any pointers is appreciated.
