Auto HiQnet Address:
When devices boot up, System Architect software, when configured to do so, will
automatically negotiate and assign a unique HiQnet™ address to each device. The devices will then keep this
address until there is a conflict at start up or the user manually assigns the device a new address.
AES/EBU:
The digital audio standard frequently called AES/EBU, officially known as AES, is used for carrying
digital audio signals between various devices. It was developed by the Audio Engineering Society (AES) and the
European Broadcasting Union (EBU) and first published in 1985, later revised in 199 and 00. Both AES and
EBU versions of the standard exist. Several different physical connectors are also defined as part of the overall
group of standards.
Auto-IP Address:
Devices and computers, if set to use a DHCP server, and a DHCP server is not present on
the network, will automatically negotiate a default IP address in the form of 169.5.xxx.xxx. This can cause
problems if you have some devices or PC’s set with static IP addresses. It is possible that addresses manually
assigned to Static IP devices may intentionally fall outside of the default Auto-IP address range and may now
be on a separate subnet and will no longer be able to communicate with devices in the Auto-IP address range.
However, if there isn’t a DHCP server on the network, then having all devices/PC’s using an Auto-IP address will
not cause any problems. In summary: all devices and PC’s on a network will need to exist on the same subnet,
whatever that may be.
DHCP:
(Dynamic Host Configuration Protocol) An established Ethernet protocol for assigning IP addresses
automatically to physical hardware devices. A DHCP server must be present on the network to provide an IP
address to each device when power is applied. With dynamic (DHCP) addressing, a device might have a different
IP address every time it connects to the network. If a DHCP Server is not installed on the network, a computer will
place a default network ID (See Auto-IP Address) into the TCP/IP address and Subnet Mask.
HiQNet:
The networking protocol established by Harman Professional to provide communication between
products for the purposes of: control, monitoring, and providing interaction between products. The protocol is
independent of the physical connection type. Typical physical connections include: Ethernet, USB, RS, RS,
Infrared, and others. For info go to http://www.harmanpro.com/hiqnet/
HiQnet Address:
The HiQnet™ address is a unique number that allows System Architect software, the PC in
use, and the connected devices, to keep track of each other on the network. The HiQnet address is completely
independent of Ethernet IP addresses.
IP Address:
(Internet Protocol address) Identifier for a computer or device on a TCP/IP network. Each device in a
network has its own identifying IP address. Example: 169.5.17.. Networks using the TCP/IP protocol route
messages based on the destination’s IP address. An IP address is made of four numbers separated by periods.
Each number can be zero to 55. The last number can never be a zero or 55. For example, 16.16.17.1 could
be an IP address. 16.16.17.0 would not be a valid IP address.
Subnet Mask (short for Subnetwork Mask):
Large networks may require subdivision into smaller groups or
subnets to keep the network more manageable. A subnet is a portion of a network that shares a common address
component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix.
For example, all devices with IP addresses that start with 16.16.16. would be part of the same subnet. IP
networks are divided using a subnet mask. A mask is a filter that selectively includes or excludes certain values.
Values that do not conform to the mask are not visible to each other. A mask is used to determine what subnet
an IP address belongs to. An IP address has two components, the network address and the host address. Like
IP addresses, a subnet mask contains four bytes ( bits) and is often written using the same “dotted-decimal”
notation. A very common default subnet mask for example is 55.55.0.0 A subnet mask neither works like an
IP address, nor does it exist independently from them. Instead, subnet masks accompany an IP address and
the two values work together. Applying the subnet mask to an IP address splits the address into two parts, an
“extended network address” and a host address. The subnet mask is the network address plus the bits reserved
for identifying the subnetwork. Dividing a network into subnets is useful for both security and performance
reasons.
System Architect:
A software application for use on Windows PC’s that provides control of HiQnet compliant
products. System Architect integrates HiQnet-compliant products within a unified control application program.
This program allows grouping, cutting and pasting of settings, custom control panels, and more. It integrates
products from Harman Professional brands using the HiQnet protocol.
