Initial System Configuration
Selecting a Sync Reference
In many applications, this server and downstream equipment connected to it must be referenced
to a common genlock source (SMPTE 170M or ITU-R-BT.470). A BNC connector is provided on the
rear panel to receive a genlock signal. It has a 75-ohm termination.
An internal crystal reference is also provided so that the server can be used as a stand-alone
player, and also for convenience for testing. Use particular care when operating the server with an
internal reference, as synchronization with other equipment may not be possible. Systems that
incorporate retiming circuitry in the router or video switcher may not require referencing.
Note that the input sync for recording is derived from the input itself. The E-E output is
synchronized to the input as well, so it is not possible to time the E-E output to gunlock.
Setting the Video Sync Source
To use with a genlocked system, select External Sync using the GUI as follows:
A. From the main menu bar select EDIT->CONFIGURE. Select the TIMING option. The
screen of Figure 9 appears.
B. Select EXTERNAL as the sync source.
C. Check that the front panel GENLOCK

GENLOCK LED is now illuminated and the word
GENLOCKED now appears in the bottom right of the main GUI window.
Genlock Signal Quality
A genlock signal for the server must conform to one of the standards listed in the Technical
Specifications. An unstable genlock source may result in unwanted artifacts in the video output .
To use in a non-genlocked system, follow the instructions above but select INTERNAL Sync.
The input to the server uses the input signal itself as a reference, this allows recording any signal
that conforms to the currently selected video format and frame rate. No configuration is
required to use this feature.
