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-AV and the
CNMSX-PRO and modular control systems CNRACKX and the 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., 198.123.456.7).
IP ID
The IP ID is a two-digit hexadecimal number that is used to differentiate a given
device from a group of Ethernet devices in a control system with the same IP
address. Just as the Net ID is used to distinguish between identical devices within a
SIMPL Windows program, the IP address for a specific IP ID in the control system’s
IP table must be set to the IP address of the given device. Furthermore, the IP ID in
the given device’s static master table must be set to the IP address of the control
system.
