Careful planning needs be made before placing a PCM96 Surround on a network that provides any access to the public. Some examples of public access are direct access to the unit from the Internet, an unsecured or weakly secured wireless network, a network jack in a public area that provides net- work access to the PCM96 Surround, or having a computer on the LAN that is not secured so that someone could use it to reconfigure the PCM96 Surround. It is highly recommended that the equipment be placed on a pro- tected, isolated network that does not have any connection to the public to prevent unauthorized users from reconfiguring the unit. Please refer to the VPN portion of this section for more information. Factory defaults for the Internet Protocol (IP) settings for the PCM96 Surround are as follows:
| 169.254.x.x (where “x.x” is determined by | |
|
| the PCM96 Surround box numbers) |
| Subnet Mask: | 255.255.0.0 |
| Gateway: | 0.0.0.0 |
| DHCP Support: | Enabled |
| Overview of TCP/IP Basics | |
| 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 peri- | |
| ods. Each number can be zero to 255. The last number should not 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 indi- | |
| cates which part of the TCP/IP address is the NETWORK ID and which | |
| part is the HOST ID. In | |
| address is the NETWORK ID”. Example: Suppose the IP ADDRESS of | |
| a device is 192.168.xx.yy and the SUBNET MASK is 255.255.x.y. That | |
| means, (192.168) is the NETWORK ID. The remaining set of numbers (xx. | |
| yy) is the HOST ID. If your network stands alone (it is not part of a larger | |
| network) then the HOST ID identifies each device in the network. If your | |
24 | network is part of a venue’s larger network, your network is actually a sub- | |
network or subnet. |
