Grass Valley iTX System v.2.6 - Manual (Page 37)

Preparing a system for iTX software
Windows sound scheme
A Microsoft Windows sound scheme, which you use to assign sounds to system events, can
disrupt the recording of audio on an Encode Server machine. Ensure all sound schemes are
disabled on Encode Server machines; alternatively, disable the Audio Service.
Direct connection to a VTR
If you want the Encode Server to be able to control a VTR (videotape machine), connect a
breakout cable with a Sony 9-pin connector between the Encode Server machine and the VTR.
This functionality requires a suitable SDI-video card to be installed in the Encode Server
machine. More details are in the iTX Hardware Specification, which you can download from the
Club iTX website.
Installing Drivers for SDI video cards
AJA video card driver version
Output Server 1 requires AJA video card driver version v7.4.0.49 and Output Server 2 requires
AJA video card driver version 12.1.0.107. Both versions of the drivers are included in the iTX
Suite, within the Drivers folder.
You can verify the version of the currently installed drivers by accessing the AJA Corvid SDI I/O
Properties or AJA Kona 3G SDI I/O Properties window from Device Manager.
Note:
• Do not use drivers that are supplied with the card or have been downloaded from the
AJA website. The required drivers for iTX are specially supplied by AJA and are included
with the iTX Suite in the Drivers folder.
• For more information on SDI I/O cards for Output Server 2, see the Output Server 2
Channel Configuration Guide.
To verify the current version of the AJA card drivers:
1. On the Windows desktop, right-click the Computer desktop icon and select Manage
from the displayed menu commands. The Computer Management window appears.
2. Within Computer Management (Local), select Device Manager. The Device Manager
window appears.
3. Expand the Sound, video and game controllers category.
4. Right-click AJA Corvid SDI I/O or AJA KONA 3G SDI I/O and select Properties.
The Properties window for your model of AJA card opens.
5. Select the Drivers tab and take note of the version number.
