Which Model to Choose?

Here are some guidelines that might help. From a programming perspective, they all behave similarly, even Analog c-pod.

Your Device Has Multiple BNC Connectors

Some EEG and other data recorders have multiple BNC connectors, one per data bit. In this case, a logical choice would be c-pod for BNC TTL. We ship it to you with a convenient breakout cable that has eight BNC connectors:

Breakout cable, provides 8 separate BNC connectors for "c-pod for BNC TTL".

The BNC Connector Can “Read” a Range of Voltages

While BNC connectors typically handle TTL input, i.e. 0 volt or 5 volts, some can detect and report a range of voltages. In this case, Analog c-pod is the choice.

Analog c-pod offers tremendous versatility. The output range can be set from 0-1V to 0-10V via our free Xidon software. When you send an event marker as a numeral, Analog c-pod automatically computes and produces the corresponding voltage level. The output range can be divided into 8 or 16 different values depending on your requirements.

In All Other Cases

Universal c-pod is the way to go. In addition to its BNC connector output, Universal c-pod offers eight additional lines of output on a separate connector. This can come in handy if you want to send event markers to two devices at the same time.

Additionally, Universal c-pod accepts eight lines of input.
