GPI / Tally Connections
The Kayak HD GPI / Tally system has universal relays that interface source
tally and GPI Output information to an external system through the Tally
Port connectors. The channels can be assigned in the Setup menu.
Tallies are a source attribute and relays can be assigned to a source when
source definitions are defined in the Setup menu during initial system con-
figuration. The nominal rating specification for each relay is 1A, 60 V.
The GPI (General Purpose Interface) and Tally Interface provides a means
to transfer commands to and from the switcher to external customer pro-
vided equipment. A “one wire per function” parallel hardware connection
is used.
Connectors and pins are provided to create a mating connector.
