Section 6 — External Interfaces
General External Device Interfacing
In general, interfacing an external device to the Karrera system involves the
following elements:
• Control cabling and configuration (Ethernet, serial ports, GPIs).
• Video cabling (Karrera Frame input connectors).
• Creating an External Device Definition (for DDR, VTR, etc.) and
assigning it to a Karrera source definition.
• Mapping that Karrera 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 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 Karrera Menu application, and Macros can be created to allow trig-
gering using Control Panel buttons.
Routing System configuration with Karrera involves establishing commu-
nications between the Karrera and Routing control systems, assigning
Router destinations to Karrera sources, and identifying which Router
sources will be accessible to the Karrera system.
Ports & Devices Menus
Control ports, GPI outputs, External Device Definitions, Serial 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 Menu
The PBus Ports Menu ( Figure 149 ) is used to configure serial ports for PBus
control of external devices. Eight PBus devices are supported, which can be
assigned to the same or different serial ports, using PBus addresses (0-7)
when the same port is used for multiple devices.
