It uses the same usb device as mentioned before by other Sony users in the past:
Thank you for your interest in the Timelapse+ product. I did some research on the Sony A7II, and I found that it can be controlled through a USB connection to a computer, but only if the computer has special software installed on on it provided by Sony. The Timelapse+ uses standardized PTP software that is used by Canon and Nikon. This is explained better in: http://www.timelapseplus.com/compatability.
The bulb-ramping mode on the TL+ requires that ISO and aperture be controlled via USB, which is not supported for the A7II. However, the shutter can still be controlled through a separate shutter-release cable, which is all that is needed for basic time-lapse mode.
A cable is connected from the remote shutter-release port on the camera to the upper-left 2.5 mm port on the TL+. Your camera would use the the S2 cable shown on: http://www.amazon.com/gp/product/B00P9FUD8A/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1http://www.timelapseplus.com/adaptor-cables. This is 2.5mm to Multi Terminal Cable for remote control shutter release. An interval and shutter speed (or bulb time) can be set in the TL+, so the it triggers your camera once per interval period.
I also mentioned another kind of cable hook-up in the forum topic on the RX100-II, where you made a reply.
