The C2N-UNI8IO is a compact interface which allows a third-party keypad to be connected directly to the Cresnet® control network.

More Details


The C2N-UNI8IO is a compact interface which allows a third-party keypad to be connected directly to the Cresnet® control network. Its low-profile design makes the C2N-UNI8IO excellent for installation directly inside a 55mm European electrical box or other suitable enclosure. Supporting up to 8 buttons and indicators, the universal keypad interface can be used in a variety of applications including homes and offices where custom styling is of the most importance, or museums and courtrooms where simple user interfaces are required.

Because it supports contact closure inputs, the C2N-UNI8IO can transform virtually any button or switch into a Cresnet device. The simple low-voltage, 4-wire bus makes Cresnet the smart choice in wiring infrastructure, allowing daisy chaining of devices for present or future needs. Simply add door sensors to systems providing indication of entry or exit, or take a doorbell to the next level by triggering the audio system when "rung."

More than just an input interface, 8 low-voltage outputs are capable of driving LEDs, relay coils, or lamps. Visual feedback is natively supported with the C2N-UNI8IO because it's capable of delivering various light intensities and blinking patterns to LEDs. Just as Crestron keypads indicate which source is selected or what lighting scene has been chosen, the universal keypad interface lets any keypad follow suit.

  • Drives up to 8 LEDs for feedback
  • Low-profile design fits in 55mm European electrical box
  • Supports 8 buttons and indicators
  • Transforms a third-party keypad into a Cresnet® device
