EVS Synapse GED100, Manual

Page: 20 / 74

GPI-Ctrl The GED100 has several physical GPI contacts to control the card’s presets (if
presets are set to be GPI controlled).
Latch : Latching GPI mode. When a contact is closed momentarily (edge triggered).
Non-Latch : Non-latching GPI mode. When a contact is closed all the time (level
triggered).
BCD : Binary GPI mode. GPI contacts work as shown in the following table:
GPI 3 GPI 2 GPI 1 Activate Preset
0 0 0 No change
0 0 1 Preset 1
0 1 0 Preset 2
0 1 1 Preset 3
1 0 0 Preset 4
1 0 1 Preset 5
1 1 0 Preset 6
1 1 1 Preset 7
Ext-Mode With this item you set the purpose of pins 5 through 8 of the RJ45 connector on the
backpanel. The pupose can be either additional GPIO contacts (resulting in 7 GPI
contacts instead of 3) or to use these pins as a Dolby
metadata I/O. Default is GPIO .
LossDetect With this setting you can set which source should be checked for the LossDetect
function (see settings Control and MD-control). When the here-set-source is lost, the
card will switch to the preset set with the
Loss setting. When the source returns, the
card will switch to the preset set with the Detect setting.
Sources which can be checked on are DolbyE , S2020-SDI , MD-LocalIn (local
metadata input) or DolbyD) . Default is DolbyE .
The aforementioned Dolby sources are detected sources and are not necessarily supported
by embedded Dolby encoders or decoders.
If LossDetect is being used, the #Emb-Mode and #Emb_A_Sel ~ #Emb_D_Sel settings need
to have the same values for both “loss” and “detect” presets to circumvent ‘reset’ of the
embedders.
This can result in Dolby and/or PCM CRC errors at the output of the embedders. If one of
these values changes, a reset is needed to guarantee audio-phase alignment for all
embedder outputs!
Loss Here you select to which of the 7 presets the card should switch in case the source
set with LossDetect is lost. When set to
off , the card will not switch presets when a
loss is detected. Default is off .
