Section 4
External Keyboard / KVM Switch
There is an inbuilt USB trackball and keyboard included with the C300HD system. These can be used for normal control
of the console's mixing and naming functions.
The C300HD console also contains additional hardware that allows its trackball/keyboard to be
used to control an external workstation and the console monitor may be used to display the
workstation's video output. The switches that control the keyboard and video selection are
located on the surround of the monitor section's LCD screen. The switches may be operated
individually or can be electronically linked – by pressing both down together – to simplify
operation.
'EXT VID' selects between the two SXGA inputs on the connector panel, 'VID 1 and 'VID 2'. 'VID
1' is normally connected to the Centuri Core. 'VID 2' is available for connection to an external
SXGA input from a PC or Mac. Maximum supported resolution is 1280 x 1024.
'EXT K/B' routes the output from the USB connector mounted in the Keyboard drawer either to the console's processor
or to the Type B USB connector on the connector panel marked 'K/BOARD'. This enables the keyboard and any connected
pointing device (Mouse, Trackball etc.) to be routed to an external PC or MAC.
A further Type B USB connector marked 'CRTL' carries USB Keyboard data generated via Console Soft Keys. This can also
be routed to a MAC or PC and used to control a DAW via its supported Keyboard short commands supplementing the
existing MIDI DAW control offered on C300. The standard connector panel includes a two port USB hub to simplify
installation by allowing the simulated USB keyboard data to be merged with the commands from the physical keyboard
connected to the console with a single USB link to the PC or MAC running the DAW software.
Two USB A-B cables are supplied with the console to connect the 'CTRL' and 'K/BOARD' USB outputs to the hub inputs.
Script Tray (option)
The script tray is a movable transparent panel which fits over a channel bay. It is fitted with rollers to allow it to be moved
along straight sections of the console.
A script tray can be added at any time as it does not require modifications to the console.
Loudspeaker Shelf (option)
A flat secure shelf is available for the positioning of loudspeakers, monitors etc. Each shelf is 400mm wide by 253mm deep.
A supporting rail is fixed to the console back panel for each speaker shelf. Additional support rails can be fitted so that
shelves may be moved to different positions along the console.
TFT External Input (option)
This option allows any of the channel bay TFT screens to be switched to show an external XGA (1024x768) video signal.
The switchover may be effected either by a GPI closure triggered from a free button or by a dedicated switch which can
be mounted on a custom panel. This option must be specified at time of order. The input will be via an HD15-pin female
connector mounted into one of the blanks on the Audio connector panel.
