KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
4
Control the VP-4x8AK using the front panel butto ns, or remotely via:
• RS-485 or RS-232 serial commands (using Kramer 2000 and 3000
protocols) transmitted by a touch screen system, PC, or other serial
controller
• The Kramer infrared remote control transmitter or infrared remote
extension cable transmitter (optional)
• The ETHERNET
The VP-4x8AK is dependable, rugged, and fits into two vertical spaces (2U)
of a standard 19” professional rack.
To achieve the best performance:
• Use only good quality connection cables1
• Avoid interference from neighboring electrical appliances that may
adversely influence signal qual i ty and position your Kramer VP-4x8AK
away from moisture, excessive su nlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables).

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
network location.
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) Address
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
(TCP/IP)
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.
