Software Development Kit & CNX Gateway Crestron e-control™
Glossary of Terms
CNX Control System
Any Crestron control processor in the CNX product line. Currently, these include the
CNMSX-PRO and CNMSX-AV.
CNX Gateway
A Crestron software package that routes control messages between the Crestron e-
control SDK and the Crestron Ethernet device.
Cresnet ID
A unique identity code, ranging from 03 to FE (in hex), given to all devices that
communicate using the Cresnet network protocol.
Ethernet Hub
Inexpensive four to 16 port devices that provide local network to destinations outside
of the local network, or receives them from outside and propagates them onto the
local network.
Gateway
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.
IP ID
A unique identity code, ranging from 03 to FE (in hex), given to all devices that
communicate using the Cresnet over IP (CIP) network protocol. Each IP ID is
associated with an IP address, determined by an IP Table which resides inside the
CNX control system.
IP Table
A table which lists IP IDs and their corresponding IP addresses. This table is
maintained inside each CNX control system, though it may be generated by a SIMPL
Windows program, or edited manually using the Viewport utility.
Network Address
A pattern of bits in IP address format that is shared by all network devices on a given
local network. For example, network address 192.168.2.0 describes the local network
where all devices have an IP address of 192.168.2.x, where x is any value from 1 to
254.
