STEP-BY-STEP SETUP PROCEDURES 

All NVIS products ship with the necessary cabling for basic monoscopic (non-stereo) operation.  
Figure 3 illustrates the setup steps for connecting your computer to the AVCU and for cabling the 
HMD to the AVCU (dual-input configuration shown).

  Connect NVIS display 

cables to the AVCU. AVCU 
connectors are color coded 
white or black and should 
match display connectors. 

  Plug the power cable 

(which includes the 
universal power supply) 
into the AVCU and into 
110-220V AC source. 

  Connect your video 

cable(s) to the computer 
and to the AVCU. 

  Connect an optional 

external monitor from the 
AVCU (two external 
monitor ports are provided 
on the back of the AVCU). 

  Connect an optional 

motion tracker. (Note: You 
might need to take 
additional steps to con-
figure your motion tracker. 
Please consult your motion 
tracker user manual for 
instructions.) 

  Power on the AVCU. 

For the headset to operate  properly,  you  need  to  make 
sure that your display is set for 1280x1024 resolution 
at  60  Hz.  Please  refer  to  Figure  4  for  an  example  of 
what your display settings should look like.
