Intan Recording Controller

The Intan Technologies Recording System is a modular family of components based on the RHD2000 series of digital electrophysiology chips that allows users to record biopotential signals from up to 1024 low-noise amplifier channels using small, affordable hardware and free, open-source software.

The Intan Recording Controller comes in a 512-channel version with four headstage ports (Part #C3004) and a 1024-channel version with eight headstage ports (Part #C3008). The Recording Controller connects to a host computer via a SuperSpeed USB 3 connection.

Small amplifier boards (headstages) connect to the Recording Controller via thin, flexible, all-digital cables that may be daisy-chained to form robust connections up to ten meters in length. Each headstage port has independent ground isolation to eliminate ground loop noise.

Included software controls the operation of the amplifiers and streams data to the screen and to disk in real time at user-selected sampling rates from 1 kS/s to 30 kS/s. The software allows users to select amplifier bandwidths, measure electrode impedances, and select between a hardware reference or digital re-referencing to a selected amplifier channel.

The Intan Recording Controller has two analog input and output ports with +/-10V range and two digital input and output ports. Analog and digital inputs are recorded in synchrony with amplifier waveforms and may be used to trigger fully automated episodic recording sessions. Analog outputs may be configured to monitor selected amplifier channels. An audio output jack facilitates real-time monitoring of any two selected amplifier signals. Digital outputs can perform low-latency threshold-based spike detection.

An optional I/O Expander (part #E6500) may be added to the Recording Controller to increase the total number of auxiliary ports to 8 analog inputs, 8 analog outputs, 16 digital inputs, and 16 digital outputs.

The Recording Controller may be mounted in a standard 19" rack (1U) or operated from a bench top.

See the Intan Recording Controller User Guide for more information on the hardware and software.

Here is the compiled version 2.06 Intan Recording Controller software for Windows and Mac (updated 14 August 2018). This software can be run without a Recording Controller; it will generate synthetic neural data for demonstration purposes if no Recording Controller is connected. For USB drivers and source code, visit our downloads page.

Note: The Intan Recording Controller does not currently work with our RHD2000 LabVIEW Library or MATLAB Toolbox. However, we do provide MATLAB code that allows data saved with the Recording Controller to be loaded into MATLAB. We also provide Python code for loading data files.
