Crestron CP4N, CP4 User Manual

CP4/CP4N

4-Series Control System

The Crestron® CP4 and CP4N are secure, high-performance control
processors with a powerful 4-Series control engine. The CP4 and
CP4Nare designed to integrate and automate technology within any
modern networked home, commercial building, or government facility. An
isolated control subnet port provides a Gigabit Ethernet LANdedicated to
Crestron devices (CP4NOnly).

NOTE:TheCP4 and CP4N are functionally similar. For simplicity within

this guide, the term "control system"is used to refer to both the CP4
and CP4Nunless otherwise noted.

QuickStart

Connect the Control Subnet
(CP4NOnly)

The CP4N has a dedicated Control Subnet that is used for
communication between the control system and Crestron Ethernet
devices without interference from other traffic on the network.

CAUTION:Do not connect the CONTROL SUBNET port to the LAN.

The CONTROL SUBNET port must only be connected to Crestron
Ethernet devices.

For more information on using the Control Subnet, refer to the 3-Series®
Control System Reference Guide (Doc. 7150) at

www.crestron.com/manuals.

Configure the Device

The control system may be configured using the provided web
configuration interface. The interface can be accessed using the control
system IP address or the Crestron XiOCloud™ service.

Configuration via IP Address

To access the web configuration interface using the control system
IPaddress:

NOTE:The control system ships with DHCPenabled. A DHCPserver is

required to access the web configuration interface via the device
IPaddress.

Configuration via Crestron XiOCloud

The Crestron XiO Cloud service allows supported Crestron devices across
an enterprise to be managed and configured from one central and secure
location in the cloud. Supported devices are configured to connect to the
service. Use of the service requires a registered Crestron XiO Cloud
account.

NOTE: The device may be disconnected from the service by navigating

to the Cloud Services tab in Crestron Toolbox software (Functions >
Device Info > Cloud Services). For details, refer to the Crestron
Toolbox help file.

To access the web configuration interface using the Crestron XiOCloud
service:

1. Connect the control system to the network.

2. Record the MAC address and serial number that are labeled on the top
of the control system. The MACaddress and serial number are
required to add the device to the service.

3. Do either of the following

l For existing accounts, access the Crestron XiO Cloud service at

https://portal.crestron.io.

l For new accounts, register for a Crestron XiO Cloud account at

www.crestron.com/xio-cloud-registration.

4. Claim the device to the service as described in the Crestron XiO Cloud
User Guide (Doc. 8214) at www.crestron.com/manuals.

5. Select the device from the cloud interface to view its settings.

1. Connect the control system to the network.

2. Use the Device Discovery tool in Crestron Toolbox™ software to
discover the control system and its IP address on the network.

3. Enter the control system IPaddress into a web browser.

QuickStart

Create an Admin Account

The first time the web configuration interface is accessed, a dialog box is
displayed asking the user to create an admin account. A similar message
is displayed when connecting to the device in Crestron Toolbox software if
an admin account has not already been created.

To create an admin account:

1. Enter a username and password for the admin account in the
appropriate text fields.

CAUTION:Do not lose the username and password for the admin

account, as the device must be reset to factory settings to regain
access.

2. Click OK. A dialog box is displayed stating that enabling authentication
will restart the web session.

3. Click Yes to confirm and restart. The username and password created
in step 1 must be entered to regain access to the web configuration
interface.

NOTE:The username and password must also be entered when

connecting from CrestronToolbox or XPanel.

Set the Time Zone

The time zone must be set on the control system to ensure that the
correct time settings are pushed to controlled devices.

To set the time zone:

1. Access the web configuration interface using either the device
IPaddress or the Crestron XiOCloud service.

2. Navigate to Settings >System Setup.

3. Select the time zone where the control system is used from the Time
Zone drop-down menu.

4. Click Save Changes on the top right of the screen.

Pair with Apple HomeKit

The control system can be paired with Apple® HomeKit® technology to
enable communication between the control system and Apple HomeKit
devices and accessories.

For pairing instructions and to locate the unique QRcode required for
pairing, refer to the CP4/CP4NProduct Information document
