VideoNet Overview
VideoNet is HP’s communication protocol used between the print server software (Including HP RIP
SW, ColorSpan ColorMark Legacy and third parties) and the printer (excluding DisplayMaker
Professional Legacy). A networking protocol is a specific software method that packages up information
for transmission over a medium, such as a cable. In this regard, VideoNet is no different from
AppleTalk, TCP/IP, or Microsoft Windows Networking.
Most network protocols, including VideoNet, require a physical medium for transmission. VideoNet
uses industry-standard 10/100baseT Ethernet hardware, including Category 5 cabling and hubs, to
physically link the printer and server. All HP VideoNet-equipped printers communicate at 100Mbs
except for DisplayMaker Express Legacy and PressMate-FS Legacy, which operate at 10Mbs only.
Each new HP printer includes a crossover VideoNet (ethernet) cable. This cable is appropriate for use
if the printer will be connected directly to the Ethernet port on the computer that is acting as the print
server. If you connect more than one VideoNet printer to a print server, or have multiple servers that will
connect to a single printer, you will need additional networking hardware to make the connection. Note:
The Legacy Personal Software RIP and RIPStation™ each support only up to 2 PressMate-FS, or any 1
(one) of the other supported VideoNet printers; consequently, the information provided in this document
has limited application to those products.
VideoNet must be Physically Segregated
In the sections that follow, VideoNet network configurations are described that involve the use of hubs
and other network hardware. It is important to emphasize, however, that VideoNet must be on a
physically separate network from you normal network. VideoNet requires all available network
bandwidth and both printer/server performance and general network performance are severely
degraded if VideoNet attempts to communicate alongside any other network protocols. This is why your
print server must have a regular network interface and a second, VideoNet-only interface.
Required Hardware and Cabling
When there is only one VideoNet printer connected to your print server, use the crossover VideoNet
cable supplied with your equipment.
When connecting multiple VideoNet devices to your print server, you will need additional networking
hardware in order to make the connections (see diagram, next page). Fast 100Base-Tx hubs, 10Base-T
hubs, 10/100 bridges, and “Smart” Hubs are readily available at any reputable reseller of networking
hardware. If more than one VideoNet printer is connected to the server, use standard Unshielded
Twisted Pair Category 5 cables and a hub to connect the print server with the printers. Category 5
cable is the only twisted pair cable rated for 100 Base-T and has 5 twists per foot. These cables may
be called “straight-through” to distinguish them from the crossover cable used to connect the printer
directly to the server.
Adding the Printers to the Server’s User Interface
In most cases, you should be able to connect all of the VideoNet devices to the hub with straightthrough cables, power them on, and add the printer(s) to the print server interface.
If this is not successful at first, troubleshoot by connecting just one printer directly to the server with the
supplied crossover cable. If the server is now able to add that device, then you have an issue with the
hub and/or other cables.
If you are still not successful, there may be a configuration problem with VideoNet on the print server.
Ensure that both the regular network interface and the VideoNet-only interface are appropriately
configured.
Supported Configurations
Below is a sample chart of some supported configurations. See your Print Server User Guide or Quick
Start Guide for detailed information on the maximum number of printers and configurations supported
with your print server.
