200 KARRERA K-FRAME — Installation & Service Manual
Section 6 — External Interfaces
General External Device Interfacing
In general, interfacing an external device to the Karrera K-Frame system
involves the following elements:
• Control cabling and configuration (Ethernet, serial ports, GPIs).
• Video cabling (K-Frame input connectors).
• Creating an External Device Definition (for DDR, VTR, etc.) and
assigning it to a source definition.
• Mapping that source to a Control Panel button.
Once configured, that external device can be selected as a source on the
Control Panel. If a DDR or VTR it can be directly controlled from the
System Bar, Device Control Module, Multi-Function Module, or from the
Karrera K-Frame Menu Panel, as well as via EMEM.
PBus and GPI control of external devices is generally accomplished by the
operator using EMEM. PBus and GPI triggers can be manually tested from
the GV Switcher menu application, and Macros can be created to allow trig-
gering using Control Panel buttons.
Routing System configuration with Karrera K-Frame involves establishing
communications between the Karrera K-Frame and Routing control sys-
tems, assigning Router destinations to sources, and identifying which
Router sources will be accessible to the system.
Ports & Devices
Control ports, GPI outputs, External Device Definitions, Ethernet Tally and
Editor Ports are configured with the Ports & Devices menus, accessed via
Eng Setup
,
Ports & Devices
, and then touching the appropriate tab.
PBus Ports
The PBus Ports menu ( Figure ) is used to configure serial ports for PBus
control of external devices. Twenty four PBus devices are supported, which
can be assigned to the same or different serial ports, using PBus addresses
(0-23) when the same port is used for multiple devices.
