KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality and position your Kramer VP-8x8TP away from
moisture, excessive sunlight and dust
to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
3.1 Terminology Used in this User Manual
Table 1 defines some terms that are used in this user manual.
Table 1: Terminology Used in this Manual
802.3 The standard specification for Ethernet that is maintained by the Institute of Electrical
and Electronics Engineers (IEEE).
Dynamic Host Configuration
Protocol (DHCP) Allows the network administrator to distribute IP addresses from a central point and
automatically send a new IP address when an Ethernet point is plugged into a different
Gateway A network position serving as an entry to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
IP Address A 32-binary digit number that identifies each sender or receiver (within a network via a
particular server or workstation) of data (HTML pages or e-mails) that is sent in packets
across the Internet. Every device connected to an IP network must have a unique IP
address. This address is used to reference the specific unit.
Local Area Network (LAN) Computers sharing a common communications line or wireless link, which often share a
server within a defined geographic area.
Media Access Control (MAC)
A computer's unique hardware number (or address) in a LAN or other network. On an
Ethernet LAN, the (MAC) address is identical to the Ethernet address.
Transmission Control
Protocol/Internet Protocol
The basic communication language or protocol of the Internet that breaks the message
into appropriately sized packets for the network, and can be used as a communications
protocol in an intranet or an extranet.
3.2 18BShielded Twisted Pair and Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable. There are
different grades of STP cable available, and we advise you to use the best quality
STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is
intended for digital signals and for analog signals where skewing is not an issue.
For cases where skewing occurs, our UTP skew-free cable, Kramer BC-XTP, may
be used. Bear in mind, though, that we advise using STP cables where possible,
since the compliance to electromagnetic interference has been tested using STP
cables.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, UTP cable should be installed as far as possible from electric cables,
motors, and so on, as these devices tend to create electromagnetic interference.
However, since the use of UTP cable might not conform to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.
