GPI / Tally Connections
The Kayenne XL 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.
Kayenne XL GPI and Tally Interface
The Kayenne XL is highly modular and configurable. This document
describes various possibilities for tally interconnections.
There are two 50 pin female subminiature 'D' connectors on the rear of the
4-RU Kayak HD frame and four connectors on the rear of the 8-RU
KayalHD-XL frame. Each connector is activated by the presence of a Mix/
Effects module installed in the frame. A one M/E switcher (4-RU or 8-RU
frame) activates only the first connector. Two M/Es activate two connec-
tors, and so forth, up to four connectors activated by a four M/E system.
GPI inputs and outputs are assigned as follows:
• GPI in 1 - 8 and GPI/Tally out 1 - 32 routed to the first connector.
• GPI in 9 - 16 and GPI/Tally out 33 - 64 routed to the second connector.
• GPI in 17 - 24 and GPI/Tally out 65 - 96 routed to the third connector
(8-RU frame only).
• GPI in 25 - 32 and GPI/Tally out 97 - 128 routed to the fourth connector
(8-RU frame only).
For pinouts of these connectors refer to the listings in:
• 4 RU and 8RU Frame Tally (GPI In 1-8, GPI Out 1-32) on page 102
• 4 RU and 8RU Frame Tally (GPI In 9-16, GPI Out 33-64) on page 103
• 8 RU Frame Tally (GPI In 17-24, GPI Out 65-96) on page 104
• 8 RU Frame Tally (GPI In 25-32, GPI Out 97-128) on page 105
These four connectors do not share any signals in common other than
ground reference and chassis ground. Because of this, some GPI / Tally
interconnects may require external common connections between connec-
tors, as explained below.
