About the Crestron CP4
The CP4 uses an embedded 4-Series multicore CPU with 2 GB SDRAM and 8 GB flash memory, and a modular programming architecture. The system can be controlled from iPhone, iPad and Android apps or through XPanel computer and web based control. The processor supports Crestron Fusion room monitoring and scheduling, XiO Cloud provisioning and management, and enterprise-class network security and authentication.
Onboard ports include eight IR/serial outputs, COM 1 for RS-232/422/485, COM 2 and 3 for RS-232, eight normally open isolated relays, eight Versiport digital input/output or analogue input ports, a Cresnet master port and gigabit Ethernet. More connectivity can be added with Crestron control port expansion modules, Ethernet to Cresnet bridges, wired Ethernet I/O modules, wireless network I/O modules or infiNET EX gateways, all sold separately.
The processor is powered by the included PW-2420RU power pack or from Cresnet (connect only one) and draws 15 W, not including connected Cresnet devices. The NET port passes power to Cresnet devices only when the power pack is connected. The black aluminium chassis is 1 RU high and can be freestanding or mounted in a 19-inch rack, with adhesive feet and rack ears included.

Questions about the Crestron CP4
What is the Crestron CP4?
It is a 4-Series control system: a rack-mountable control processor with a 4-Series control engine and numerous integrated control ports. It is designed to integrate and automate technology in networked homes, commercial buildings and government facilities, and supports app, XPanel and web based control.
What is the difference between the CP4 and CP4-R?
The CP4 is the standard 4-Series control system for custom programmed and commercial systems. The CP4-R is the version with the Crestron Home operating system built in, set up with the Crestron Home Setup app instead of a custom programme, and it has its own page in our Crestron shop.
What control ports does the CP4 have?
It has eight IR/serial outputs, COM 1 for RS-232/422/485, COM 2 and 3 for RS-232, eight normally open isolated relays rated 1 A at 30 VAC/VDC, eight Versiport I/O ports, a Cresnet master port, a gigabit Ethernet LAN port, a rear USB 2.0 host port and an SD card slot.
How is the CP4 powered?
It comes with the PW-2420RU power pack, which takes 100-240 VAC and outputs 2.5 A at 24 VDC. It can instead be powered from Cresnet, but only one source should be connected. The processor draws 15 W, not including connected Cresnet devices, and the NET port powers Cresnet devices only when the power pack is connected.
How is the CP4 mounted?
It is 1 RU high and can be freestanding or mounted in a 19-inch rack; adhesive feet and rack ears are included. It measures 44 mm high without feet, 439 mm wide (483 mm with rack ears) and 167 mm deep, in a black aluminium chassis.
How much is the Crestron CP4?
Crestron asks its dealers to give the price of the CP4 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 CP4?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the CP4 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 CP4 come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the CP4 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 CP4 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 CP4 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.
