Worry Free Event Markers

Precise, Asynchronous, Plug-and-Play USB to TTL

Picture of c-pod family. Over a dozen models are available for different EEG, eye tracker, NIRS, and other recorders.

High Precision

Where timing precision is vital, you need c-pod. We packed it with a speedy 32-bit microprocessor, a separate, dedicated USB interface chip, and top quality USB drivers for your Mac and PC.

Turnkey Solution

We deliver c-pod ready to connect. The correct pin assignments. Mating connector. Matching TTL or analog signal. And where necessary, built-in optical isolation for the highest signal quality. 

Available Models By Manufacturer

By Connector Type OR Signal

If your product is not listed, please contact us. Chances are we have a solution.

  • 2.5mm or 3.5mm round jack
  • BNC / coax
  • Analog signal
  • Parallel Port


  • Universal Model  [coming soon]
    Offers input as well as output / customizable to a degree.

Analog Support

If your device accepts analog input (e.g. Nihon Kohden), we support that as well. The Analog c-pod model divides the voltage range into 8 or 16 and generates corresponding voltage levels with an excellent 1% precision.

The voltage range can be between 1 and 10 volts, easily set in software.

Dedicated USB interface chip for best timing.

Powerful 32-bit, 44-pin microprocessor with built-in flash memory.

“Set and Forget” Output

Asynchronous output distinguishes c-pod from all other products on the market.

In the past, software that wanted to send a 20ms long event marker had to pause running for 20ms. In fields like neuroscience and psychology, 20ms is forever. With c-pod, the software sends a command and proceeds – no pausing. 

c-pod has even more advanced features, like a pulse scheduler and a pattern generator; see Specifications.

Software Support

c-pod enjoys extensive software support. Some packages can deliver jitter free performance.

Jitter Free Support

  • SuperLab 6
    Free upgrade to all SuperLab 5 users.
  • Python Library
  • C++ Library
  • Inquisit

Others

  • E-Prime
    We offer an E-Basic code sample. Precision is about ±5ms.
  • Presentation

Jitter Free USB

When sending event markers via USB, c-pod delivers them with jitter free precision when used with SuperLab 6 or with our open source Python or C++ libraries.

Delay is guaranteed to be 2ms exactly, every time.

Ships Complete

c-pod ships complete and ready to connect to your device. All models include a USB cable. Some include other accessories needed to make sure it’s a true plug-and-play experience.
