Crestron CEN-IO

Master list is a list of Crestron Internet Protocol (CIP) enabled devices that will be 
informed of any changes in the state of the controlled device. The device accepts 
commands from the addresses of these masters. 

NMS trap catcher is the address of a SNMP monitoring station that sends any alarm 
messages that the monitored device wishes to send. 

Router is a communications device which routes data between networks. 

SNMP stands for Simple Network Management Protocol. It is part of TCP/IP that 
deals with managing the devices in a network.  

TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is quite simply 
a standard set of protocols that govern the basic workings of the Internet that was 
implemented in 1982.  

The TCP part is all about ensuring that data is transmitted correctly between two 
computers. If any errors occur these are detected and the data is retransmitted. The 
data transmitted is split up into small portions called data packets. The IP part of 
TCP/IP is how these data packets are moved from one point to another. Each 
computer on the internet has a unique IP address and the data packets are moved 
from the source to the destination through many different computers which is 
controlled via TCP/IP. This protocol is used on the Internet and also by computers 
that are part of a LAN.
