‍Summary

‍A number of EEG and other biometric recorders use BNC connectors.

‍Important: As the name implies, m-pod for BNC TTL generates TTL signals, i.e. 0 or 5 volts. Check your documentation or ask the manufacturer to make sure that your recorder’s BNC connector can handle a 5 volt input. If it does not, then you probably need Analog m-pod instead.

‍m-pod for BNC TTL has two connectors:

• A BNC connector, handy for when you need a single bit of output (or when your recorder offers a single BNC connector).
• A DB15 connector that offers 8 bits of output. Your unit comes with a breakout cable. It connects to the DB15 connector on one end and has 8 BNC connectors on the other end.

‍Default Output Signals

‍On the breakout cable, the wires have a white tag. The leftmost column shows the tag number.

‍When Connected to a Riponda or RB-x40 Response Pad

‍Note: When used with a Lumina 3G controller, the same info applies, with the difference that key presses 5 through 8 correspond to keys 1 through 4 on “Response Pad 2”.

‍Customizing The Output Signals

‍m-pod contains a powerful microprocessor that can reassign any input signal to any output line, and without any significant delay. It can also assign multiple signals to the same output line.

‍The tables above describe the factory default. If your experiment or lab setup requires different output, Cedrus provides a free utility for configuring your m-pod. After you use it, your configuration is saved to flash memory so that it’s remembered even after you power off m-pod.
