Hardware installation guide
Audio and displays
Follow installation instructions for your selected speakers and displays.
For BITTSy to display image and video stimuli, your system's display settings should be set to Extend mode. See here for instructions on changing Windows 10 display settings.
There are several audio issues that can be identified during setup that can cause problems for experiments in BITTSy (or any other experimental software) later. See this section for more info.
Lights
Connect the USB-DMX interface box (such as ENTTEC DMX USB PRO) to the computer tower. Both ends should be USB ports (albeit different types).
Connect your dimmer/switch pack (such as DP-415 unit) to a power source.
Connect the USB-DMX box to the dimmer pack. The connection between them should be DMX OUT on the USB-DMX box to DMX IN on the dimmer pack. The outputs of the dimmer pack are only for the lights.
Connect dimmer pack to the lights. If you wish to control each light individually (as in a headturn preference setup with a left, center, and right light), ensure that they are plugged under separate numbered channels. The numbering of the channels on your dimmer pack will generally match with the device IDs used by BITTSy, but this will be confirmed later when you run the BITTSy setup protocol!
If you have the DP-415 unit, be sure that notches 1 & 10 are flicked to the “ON” position (toward the top). Notch 1 sets the starting DMX address to the lowest (the options 2-9 are unneeded), and notch 10 makes it function as a switch pack.
Check for necessary firmware/drivers for your USB-DMX interface box. If you purchased from ENTTEC, see the Downloads section at the bottom of the product page (here for the ENTTEC DMX USB Pro); download and install both the Win D2XX driver and the recommended firmware.
After everything has been successfully installed, this is what the booth looks like:
