User manual
6. A different network number must be specified for each EVS video server that you
want to connect to the network. If the same network number is assigned to 2 different
systems, the second one will not be able to connect and a warning message will be
displayed.
7. All EVS video servers must be connected with a good quality BNC 75Ohm cable to
form a closed loop. Connect the SDTI OUT connector of the first EVS video server to
the SDTI IN connector of the second one, etc until the loop is closed by connecting
the SDTI OUT connector of the last EVS video server to the SDTI IN connector of the
first one. The SDTI loop must be closed at all times during network operation. If for
any reason the loop is open, all network communication will be interrupted and all
systems will automatically switch to stand alone mode. When the loop is closed
again, network operation will resume automatically. This problem can be avoided or
limited using EVS XHub SDTI hub.
8. The distance shown in the table below is the maximum cable length between two
active EVS servers, or 2 SDTI reclockers, on an XNet2 SDTI network, using a single
piece of cable between 2 servers or 2 reclockers. Intermediate connectors, patch
panels, etc., might degrade these figures. Depending on the number of servers
connected on the network, the location of the master server, the presence or not of an
XHub SDTI hub, the actual maximum values may be higher than indicated. If longer
distances between servers are required, SDTI to Fiber converters can be used,
allowing distances over thousands of meters if necessary. EVS has validated the
following SDI-Fibre converters:
◦ Stratos Lightwave Media Converter TX/RX VMC-T-H-2/VMC-R-H-2
(www.stratoslightwave.com)
◦ Telecast TX/RX292 (www.telecast-fiber.com)
◦ Network Electronics SDI-EO-13T (electrical to optical) / SDI-OE-S (optical to
electrical) (www.network-electronics.com)
◦ Network Electronics HD-EO-13T (electrical to optical) / HD-OE (optical to
electrical)
◦ BlueBell BB320T (TX) and BB320R (RX) (www.bluebell.tv)
Cable type @ 1485 Mbps
RG59 45m / 148ft
RG6 90m / 484ft
RG11 120m / 393ft
Super HiQ 150m / 492ft
Fiber 80km (*)
(*) 80km/200km is the total length of the return path, i.e. the actual distances between
the 2 servers connected via the fiber link is half of this value, i.e. 40 km @ 1485 Mbps.
Note
When reclockers are used, the total delay induced by these reclockers between
2 active servers on the network may not exceed 15 μs.
