7. Operation  
7.1 Opening and Closing the Cable Nook Jr. 
Lift the Cable-Nook Jr.’s cover to install or route cables. If the cables need 
to  be  connected  while  the  lid  is  closed,  route  the  ca bles  through  the  open 
space  in  the  front  of  the  lid.  Unconnected  cables  may  be  stored  inside the 
Cable-Nook Jr. until they are needed. 
7.2 Power/Signal Connections 
Connect external devices to the appropriate cable f rom the Cable Nook Jr. 
Remember, the devices plugged into the AC power conn ectors should not

7.3 Output/Display Select 
Connect the Display Select cable with terminal block
 connector to the 
input of the UT250-101 Under-Table Switcher.  
The UT250-101 can be configured for various modes of  operations. The 
output select buttons behave differently depending o n the precise 
configuration. In the default configuration, the ou tput select buttons have 
the following behavior: 
CNK321 with No Video Signal Applied: 
Pressing either output select button wakes up the syst em up, 
turns on the display, and then directs the video from  Input 8 to 
all outputs. Input 8 is typically used for a logo, scr eensaver, or 
demonstration video. 
CNK321 with Video Signal Applied:  As soon as the UT250-101 detects a video signal, the syste m 
wakes up, turns on the display, and switches Input 8  to all 
outputs. Input 8 is typically used for a logo, screensav er, or 
demonstration video.  
Press Output Select 1 button to direct the audio and  video from 
the CNK321 to Outputs 1A and 1B. Press the Output Sel ect 1 
button a second time while its LED is on to switch the  input 
from the CNK321 to Input 8 on the UT250-101. Output  Select 2 
operates the same except it directs the audio and vid eo to 
Outputs 2A and 2B.

Symptom  Resolution 
No Display on Projector  
  or Monitor  1.  Check the source and make sure there is a signal pr
esent. 
2.  Make sure the projector has power and is turned on . If the projector power is controlled by the switcher through 
RS-232 control, make sure the cables are connected an d the correct codes have been selected. 
3.  Make sure the correct input is selected at the CNK 321. 
Poor Output Image 1.  The source resolution may not be compatible with t
he projector or other display device. Try other resolutions from 
the source. 
2.  The source and display may not be compatible. Conn ect the source directly to the input of the projector or other 
display device. If the image is poor the devices may b e incompatible. 
3.   Use high-quality cables, especially if making long  cable runs. Cable quality does affect image quality. 
No Sound 1.  Make sure the amplifier or speakers are connected 
to the speaker output on the switcher.  
2.  Make sure an input is selected and that the input  has audio playing. 
3.  The output audio plays the audio from the last sel ected source. Make sure the last selected source has aud io playing. 
4.  Increase the source volume.   
5.   Some audio sources require amplification to be heard on overhead speakers. Check the audio level and m ake sure 
the source level is compatible with the speakers.
