GPI/O Connections
GPI/O:
This 15 pin female high density ‘D’ connector (
AUX I/O
) contains several general-purpose
control inputs and outputs. The inputs are used to connect manual or automatic triggers for
the display or insertion of media. The outputs provide feedback on internal unit status of the
downstream keyer. See section 2.8 for information on connecting the general-purpose
inputs and outputs. For information on configuring the GPI and GPO functions, see section
4.8 for VLPRO Configuration and sections 5.11.1 and 5.11.2 for RCP Configuration.
