8Appendix A: TCP-IQ Network Basics

8.1Glossary

The following glossary explains network terminology. It is arranged in logical order rather than alphabetical order.

Network: A group of interconnected components, such as a central computer, network switching equipment, and other computers or devices.

TCP/IQ network: A network made of a computer, network switching equipment, and other audio devices such as IQ- PIP cards plugged into power amps. Since each I-Tech amp connects directly to a network, each amp is also a network component.

Subnet: A small network within a larger network. For example, a TCP/IQ audio network might be a subnet of a venue’s network, which could include computers through- out the building. Or an audio network might be divided into subnets. For example, one audio subnet might be for the house system and another audio subnet might be for the paging system.

IP address: An identifier for a computer or device on a TCP/IP network. Each device in a network has its own IP address to identify it. Example: 126.126.17.42. Networks using the TCP/IP protocol route messages based on the IP address of the destination. An IP address is made of four numbers separated by periods. Each number can be zero to 255. The last number can never be a zero or 255. For example, 126.126.17.1 could be an IP address. 126.126.17.0 would not be a valid IP address.

A TCP/ IP or IP address has two parts: the NETWORK ID and the HOST ID. The NETWORK ID identifies the network, and the HOST ID identifies either the subnet and device, or just the device if there is no subnet.

The subnet mask is a code that indicates which part of the TCP/IP address is the NETWORK ID and which part is the HOST ID. In subnet-mask code, 255 means “This part of the address is the NETWORK ID”.

Example:

Suppose the IP ADDRESS of a device is 126.126.17.42 and the SUBNET MASK is 255.255.0.0.

That means, (126.126) is the NETWORK ID. The remaining set of numbers (17.42) is the HOST ID. If your audio net- work stands alone (it is not part of a larger network) then the HOST ID identifies each device in the network.

If your audio network is part of a venue’s larger network, your network is actually a sub-network or subnet. In this case, the HOST ID can be further divided into two or more parts. The first part is the SUBNET ID. The other part is the DEVICE ID. The first part of the HOST ID identifies the sub- net of your audio system, and the remaining part identifies the particular device within that subnet.

So in this case, a complete IP address is in the form

NETWORK ID - SUBNET ID - DEVICE ID.

All devices in the network have the same network ID. All devices in a subnet have the same subnet ID.

There are many resources available on the Internet for IP and subnet calculation. For a stand-alone system, Crown has provided a worksheet of a tested configuration in Sec- tion 1.2.5.

DHCP (Dynamic Host Configuration Protocol): This is a protocol for automatically assigning IP addresses to devices on a network. With dynamic (DHCP) addressing, a device might have a different IP address every time it con- nects to the network. If a computer is NOT connected to a network with a DHCP server, the computer will place a default network ID into the TCP/IP address and Subnet Masks.

TCP/IQ does not use DHCP. A computer attached to a TCP/IQ network must have its IP addresses assigned stati- cally (manually).
