NOTE: The control system ships with DHCP enabled. To access the web configuration interface using the control system IP address:

The interface can be accessed using the control system IP address or the XiO Cloud® service.

The control system may be configured using the provided web configuration interface. The CONTROL SUBNET port must only be connected to Crestron Ethernet devices.įor more information on using the Control Subnet, refer to the 4‑Series™ Control System Reference Guide. 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.ĬAUTION: Do not connect the CONTROL SUBNET port to the LAN.

A ground terminal connection is recommended but not required.

If necessary, RXD+/RXD- and TXD+/TXD- may be swapped to maintain correct signal levels. RXD- and TXD- should idle low (going high at start of data transmission). RXD+ and TXD+ should idle high (going low at start of data transmission).

RS-422 transmit and receive are balanced signals that require two lines plus a ground in each direction.

Apply power after all connections have been made.

Connect the chassis ground lug to a known earth ground circuit (such as building steel) to ensure that the control system is grounded properly.

The control system may be powered with the included 24 VDC power supply or via Cresnet® network power with the NET port.

Use Crestron power supplies for Crestron equipment.

Observe the following when connecting the control system: Make all necessary connections to the control system as shown below.

Place onto a flat surface or stack with other equipment.

Attach the four adhesive rubber feet near the corners on the underside of the control system.

Mount the control system into the rack with four mounting screws (not included).

Attach the two included rack ears with the removed screws.Use a #1 Phillips screwdriver to remove the six required screws from the control system assembly (shown in the illustration below).The control system occupies 1U of rack space. The control system may be mounted into a rack or placed onto a flat surface. Use the following procedures to install the CP4 and CP4N control systems.
