About the Crestron C2N-UNI8IO
Its inputs read contact closures, so almost any button or switch, not just a keypad, can become a Cresnet device through the C2N-UNI8IO. Its 8 low-voltage outputs can drive LEDs, relay coils or lamps, and it can give LEDs various light intensities and blinking patterns, so a third-party keypad can show which source or lighting scene is selected, as Crestron keypads do.
Cresnet runs on a low-voltage, 4-wire bus with devices daisy chained along it, so the interface can join an existing Cresnet run. Its low-profile design suits mounting directly inside a 55 mm electrical box or another suitable enclosure. Door sensors are another example of contact closure devices that can be brought into a Crestron system this way, providing indication of entry.

Questions about the Crestron C2N-UNI8IO
What does the Crestron C2N-UNI8IO do?
It is a universal keypad interface. It links a third-party keypad straight to the Cresnet control network, so the keypad works as a Cresnet device, and it handles up to 8 buttons and indicators and up to 8 feedback LEDs.
Can the C2N-UNI8IO work with switches other than keypads?
Yes. Its inputs read contact closures, so almost any button or switch can be brought onto Cresnet this way. Crestron gives door sensors as an example, used to give the control system an indication of entry.
What can the outputs on the C2N-UNI8IO drive?
Its 8 low-voltage outputs will drive LEDs, relay coils or lamps. For LEDs it can produce various light intensities and blinking patterns, so a third-party keypad can show feedback such as which source or lighting scene is selected.
Where does the interface mount?
The interface is low profile, so it can sit directly inside a 55 mm electrical box or another enclosure of suitable size. From there it connects to the Cresnet control network, which uses a low-voltage, 4-wire bus.
How does it connect to the Crestron system?
It connects over Cresnet, a low-voltage 4-wire bus. Devices are daisy chained along the bus, so more can be added now or later. Once connected, the third-party keypad or switch acts as a Cresnet device in the Crestron control system.
How much is the Crestron C2N-UNI8IO?
Crestron asks its dealers to give the price of the C2N-UNI8IO directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the C2N-UNI8IO?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the C2N-UNI8IO on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the C2N-UNI8IO come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the C2N-UNI8IO develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the C2N-UNI8IO in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the C2N-UNI8IO without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
