Crestron CEN-CN Ethernet/Cresnet Interface

Glossary of Terms

CIP

Cresnet (over) Internet Protocol is a combination of Cresnet and Internet protocols. On a regular Cresnet network (such as a CNMSX talking to a CT-3000 touchpanel) the low-level protocol that handles communications (such as "Digital 1 Pressed on Cresnet ID 05") is called Cresnet Protocol. The same protocol is used when speaking eControl devices (CEN-COM, CEN-IO, eControl touchpanels, TPS touchpanels over ethernet, etc.), except that it is packaged into the IP protocol that is used on the Internet and referred to as Cresnet over Internet Protocol.

CTP

Crestron Terminal Protocol is the protocol used when the viewport establishes a connection via REMOTE -> TCP/IP CONNECT and only an IP Address is given. The port number is assumed to be 41795, which is the port number that CTP uses for communications.

CNX Control System

A CNX control system is any Crestron control processor in the CNX product line.

Currently, these include the integrated control systems CNMSX-PRO and the

CNMSX-AV and modular control system CNRACKX/-DP.

Cresnet ID

Cresnet ID, a unique identity code ranging from 03 to FE (in hexadecimal), is given to all devices that communicate using the Cresnet network protocol.

Default Router

A default router is a router that sends packets within the local network to destinations outside of the local network, or receives them from outside and propagates them onto the local network. It is also referred to as a Gateway.

Ethernet Hub

Inexpensive four to 16 port devices that provide a way to physically tap into an existing Ethernet connection and expand the plugs available, but do not perform any packet routing.

Gateway

See Default Router above.

IP Address

Internet protocol address is a unique number that is used to represent every single computer in a network. All the computers on the Internet have a unique IP address. The format of the IP address is four numbers separated by dots (e.g., 198.168.0.1).
