EVS Synapse GDK200, Installation And Operation Manual, Page: 18 / 56

5. Settings Menu
5.1. Introduction
The Settings menu displays the current state of each GDK200 setting and allows you to change or
adjust it.
Settings can be changed using the front panel of the Synapse frame (SFR18, SFR08 or SFR04) or with
Cortex. The SCP08 control can also be used. Please refer to "Quick Start" on page 3 for information on
the Synapse front panel control and Cortex.
5.2. Control
Setting Description
Inp_Format With Inp-Format you can set the input format. Possible settings are:
• 1080p60 • 1080p50 (default)
• 1080i60 • 1080i50
• 720p60 • 720p50
• SD525 • SD625
The default setting for this item is 1080p50.
Lock-Mode With this setting you select to what the card should lock to: input1, ref1, ref2. Can
also be set to RefAuto.
When set to RefAuto the card chooses ref1 as its source. Whenever ref1 fails, it
will switch to ref 2 (only for SFR08 and SFR18 frames and only when ref2 offers
the same ref format as ref 1). When ref 1 is back up again, it will only
automatically switch back to ref 1 when ref 2 fails.
Please be aware that the GDK200 does not have a built in frame-synchronizer. This means
that all inputs should already be locked to the lock-source (ref1, ref2 or input1). This should
be accurate within the values stated on page 12 under the paragraph ‘Important notice about
input specifications’.
Ref-Type The GDK200 is able to lock onto an HD sync 600mV nominal Tri-level as
described in the SMPTE 274M and 296m spec. An SD sync 300 mV nominal Bi-
level sync can also be used. Ref-Type sets the type of reference to Tri-level or
Bi-level.
The default setting is Bi-level.
