5.6. Check Automatic Fail-Safe (Default) Operation
This procedure will verify that, should the D600 timecode reader fail for any reason, the system will
automatically switch to the predefined optical sound format.
1. While the demo film is running, block the timecode at the reader or unplug the 9-pin connector at
the reader.
To block the timecode reader, insert a business card between the film and the lens of the D600
Timecode Reader Head and keep it there for at least six seconds.
2. Verify that after 4 to 5 seconds of not seeing timecode, the XD20 switches to the SR optical
sound format.
There should not be a dramatic sound level difference when the cinema processor switches from
digital to analog during
dialog scenes . If there is a dramatic difference, check the cinema
processor’s levels first, then check the XD20 levels, and test again.
Remember, the XD20 output level must match the cinema processor’s buss level.
3. Now, restore timecode and the XD20 should automatically switch the cinema processor to the
DTS digital format after about two seconds.
4. For two-projector theaters, repeat this procedure for Projector 2.
5.7. Networking multiple XD20s
Note: It is always advisable to consult with an IT professional when networking the players.
The Network Transfer feature enables the XD20s distribute feature audio and CSS content to all players
in the network. Video content will not be transferred. Content loaded into any of the XD20s using
network transfer will automatically be distributed to all players on the network. To connect multiple
XD20s in a local network, it is necessary to connect each XD20 using CAT 5e or CAT 6 Ethernet cable to
a network switch or router, depending on the requirements of your system. Whether using a network
switch, a router, or connecting to an existing LAN, it is necessary to make sure that Network Transfer is
set to “
Enable ” for each XD20 on the network. (Full menu path is Setup

Notes –
1. When content is deleted from an XD20 (manually or automatically), then it is not copied from
the other unit(s). It
will be copied if it is reloaded from a disk.
2. Delete all film content before adding a unit to the network - OR - delete all film content before
enabling the network. This will prevent all other units on the network from trying to update
their content with content from the newly installed unit.
5.7.1. Stand-Alone System using Switches and Routers
Two methods of connections can be done when using network transfer feature. If you have a closed
system and only the XD20s will be connected, a simple network switch (hub) can be used to allow all
XD20s to communicate with each other. This method requires each unit to be manually issued an IP
address.
You may also connect several XD20s in a closed system using a router. This method is simpler, and is
also discussed below.
5.7.1.1. Setup Procedure with a Network Switch
The following steps are done after Ethernet cables have been installed and connected to all XD20s and
passed through a network switch. See drawing H319 in
Appendix B .
