Our newest and most powerful optical interface unit yet, the Birch interface offers the works-with-everything, standards-based data output you know and trust from Current Designs in a slick, mountable package. This is a drop-in replacement for the 932 interface and compatible with all your existing handhelds. An easy-to-read touchscreen displays responses as they happen and simplifies mode selection.

When your session is over, take an independent time-stamped record of your subjects' responses in your pocket on a USB thumbdrive.

Based on years of feedback from users, this latest interface has been updated for 2020 with wireless network connectivity for easy firmware updates and an improved form factor that allows you to get the interface off the console tabletop and into a permanent location for easy access and simplified cabling.

The Birch interface, like the 900 series of interfaces, adheres to USB HID standards and will work with any operating system or program you choose, but with an added Raspberry Pi single board computer it brings new potential for stimulus delivery and response collection in a single compact package.
