Device Definition
The switcher system uses a software External Device Definition object to define the
capabilities of each device interfaced with the system.
Use the Ports & Devices menu to define external devices.
External Device Definitions contain the interface information required for that external
device, (e.g., IP Address or Serial Port). Each Device Definition is given a unique name. Once
a Device Definition has been created for a device (DDR, or VTR), it can be assigned to a
source. That source then supports the specific capabilities of that external device. (PBus and
GPI configurations are different, and are not associated with a particular source.)
Selecting an already defined item in the scrolling External Devices list on the left brings up
information for that device and delegates the rest of the menu to that object.
Device Name – Touching this button opens an alphanumeric keypad used to give the
External Device a descriptive name. These names appear in the Control Panel System Bar
and GV Switcher menus.
Note:
When configuring servers with multiple channels, the channel
number must be appended to the device name with a - character, and the
base name be the same for all channels on the same server (e.g. 'Vdr4-1',
'Vdr4-2', etc.).
Type – Chooses a control protocol for the currently selected device.
• For Ethernet devices, and IP address field is available for entering the IP address of the
External Device.
• For serial control devices, selecting a Port button on the right assigns the selected
device to that port in the Ports & Devices, External Devices menu.
Unassign Ext. Device – Clears the definition of the selected item.
