Crestron CP4 User manual

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.

Connect the Control System
Make all necessary connections to the control system as shown below.
Observe the following when connecting the control system:
lUse Crestron power supplies for Crestron equipment.
lThe control system may be powered with the included 24 VDC power
supply or via Cresnet® network power with the NET port.
lConnect the chassis ground lug to a known earth ground circuit (such
as building steel) to ensure that the control system is grounded
properly.
lApply power after all connections have been made.

1. RS-422 transmit and receive are balanced signals that require two lines plus a ground
in each direction. RXD+ and TXD+ should idle high (going low at start of data
transmission). RXD- and TXD- should idle low (going high at start of data
transmission). If necessary, RXD+/RXD- and TXD+/TXD- may be swapped to maintain
correct signal levels.
2. A ground terminal connection is recommended but not required.

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
4-Series™ Control System Reference Guide.
Configure the Control System
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 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 control
system IPaddress.
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.
Configuration via XiOCloud
The XiOCloud®service allows supported devices across an enterprise to
be managed and configured from one central and secure location in the
cloud. Supported Crestron® devices are configured to connect to the
service out of the box.
Use of the service requires a registered XiOCloud account. To register
for an XiOCloud account, refer to
www.crestron.com/Support/Tools/Licensing-Registration/XiO-Cloud-
Registration-Room-Licenses.
NOTE:The device may be disconnected from the XiOCloud 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 connect the device to the XiOCloud service:
1. Record the MAC address and serial number that are labeled on the
shipping box or the device. The MAC address and serial number are
required to add the device to the XiOCloud service.
NOTE:If the device has multiple MAC addresses, use the MAC
address that is providing the primary connection back to the
network. For most devices, the Ethernet MAC address should be
used. However, if your device is connecting to the network over a
different protocol (such as Wi-Fi® communications), use the
MAC address for that protocol instead.
2. Log in to your XiOCloud account at portal.crestron.io.
3. Claim the device to the XiOCloud service as described in the
XiOCloudUserGuide.
Select the device from the cloud interface to view its status and
settings. The device may now also be managed and assigned to a group
or room. For more information, refer to the XiOCloudUserGuide.

NOTE:For XiOCloud accounts with room-based licenses, the device
must be added to a licensed room before its status and settings can be
viewed.
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 control system 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 control system 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
(Doc.8536)that shipped with the control system.
