INPUT-OUTPUT.
Use the left ( ◄ ) or right ( ► ) arrow button con fi gure the
BLACK 1 connector as an INPUT or an OUTPUT . This connector is forced to
be an input if the TIMING REFERENCE SOURCE is set to a Genlock signal or if
VITC is the TIME OF DAY reference.
NOTE.
If a reference signal is connected to the BLACK 1 / REF IN connector, you
should con fi gure this connector as an input so that the GPS7 module does not
output a video signal if the Reference Source is changed to GPS or internal.
This might occur when using the GPS7 module in a dual-con fi guration where the
module is being switched between being a slave via genlock to incoming video or
a master source using the GPS reference.
NOTE. This submenu is available only when BLACK 1 is selected for con fi guration
and the module has the BLACK 1 / REF IN connector.
