5. Network Type must be set to “Server” on 1 (and only 1 !) XT on the
network. The others must be set to either “Master” (to share clips
and view others’ clips) or “Client” (to share clips only).
6. A different network number must be specified for each XT system
that you want to connect on 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 XT’s must be connected with a good quality BNC 75Ohm cable to
form a closed loop. Connect the SDTI OUT connector of the first
XT to the SDTI IN connector of the second one, etc until the loop is
closed by connecting the SDTI OUT connector of the last XT 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 a XNet
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 a 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 folowing SDI-Fibre converters :
a. Stratos Lightwave Media Converter TX/RX VMC-T-H-2/VMC-
R-H-2 (www.stratoslightwave.com)
b. Telecast TX/RX292 (www.telecast-fiber.com
)
c. Network Electronics SDI-EO-13T (electrical to optical) / SDI-
OE-S (optical to electrical) (www.network-electronics.com)
d. Network Electronics HD-EO-13T (electrical to optical / HD-
OE (optical to eleltrical)
e. BlueBell BB320T (TX) and BB320R (RX) (www.bluebell.tv)
Cable type @ 540 Mbps @ 270 Mbps
RG59 100m / 300ft 200m / 600ft
RG11 250m / 750ft 400m / 1200ft
Super HiQ 350m / 1050ft 550m / 1650ft
Fiber 200km(*) 400km(*)
(*) 200km/400km 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. 100 km @ 540Mbps or 200km @ 270Mbps.
Note : When using reclockers, the total delay induced by these reclockers between
2 active servers on the network must no exceed 15µs.
