2. Installation Procedures 
CAUTION: Do not handle the unit by the bezel’s thin lip or lay it on its side. The thin bezel is very sharp and can be easily dented or 
bent. Handle by the housing portion only. 
Step 1. Cut an opening in the table’s surface. Refer to www.altinex.com for 
table cutout dimensions and templates. The tabletop thickness must 
be 3 in [76 mm] or less. Always confirm dimensions before cutting to 
ensure that the specifications have not changed. 
Step 2. If needed, adjust the interior bracket mounts to the level you require 
by removing the two screws securing each bracket to the interior 
housing. Make sure both sides are at the same level. 
Step 3. Insert the Cable-Nook Jr. unit into the tabletop cutout. Place a 
mounting bracket with the thumbscrew installed into the support 
mounts on each side of the housing as shown. With the mounting 
brackets installed, turn the thumbscrews until the ends of the screws 
begin to push against the bottom of the table. Tighten the screws 
until the unit is secure. Do not over-tighten. 
3. Limited Warranty/Return Policies 
Please see the Altinex website at www.altinex.com for details on warranty and return policies.

5. About Your Cable-Nook Jr. (CNK Jr.) 
 Easy installation into tabletop 
 Convenient access to cable ends or fixed connectors 
 Modular configuration: more room for additional connectors 
 Simple, cost-effective interconnect solution 
 12 Amp AC module with 9.5 ft. (2.9 m) power cord on CNK241/261/341/361 
 Wide variety of custom plates available 
The CNK Jr. interconnect box is designed for installation into a conference room or boardroom table. The CNK Jr. provides a means 
of connecting audio, video, and other multimedia sources into a presentation system. It is ideal for use with Altinex computer video 
interfaces or distribution amplifiers. It provides a simple yet effective way of storing and hiding cables, eliminating the obstruction. 
Cables remain connected to a presentation system, enabling the user to connect them to different media sources needed for a 
presentation. After the presentation, the cables are returned to the nook for safe storage. 
The CNK Jr. is designed for use with tabletops up to three inches thick. Optional insert plates are available to secure the cable ends 
or to add connections for a variety of multimedia and power cables. The insert plates can be adjusted to fit a variety of cable sizes. 
The height of the insert plates can also be adjusted by changing the height of the interior bracket mounts in the Cable-Nook Jr. 
CNK221/241/261 
The CNK221 is an empty enclosure with only the interior mounting brackets; select from a wide variety of Altinex custom plates, or 
design and build your own custom panels. The CNK241 is preconfigured with a dual AC power module and 5 retaining rails that can 
be adjusted to hold up a wide variety of cable types. The CNK261 is preconfigured with a dual AC power module and 2 cable retainer 
grommets specifically designed to be used with Altinex retractable cables. 
Stackable Bezel 
The CNK221/241/261 come standard with a mounting bezel. One CNK Jr. is installed in one table cutout. If more CNK Jr.’s 
are needed in a limited space, stackable bezels come in 2, 3, and 4-up options. A single cutout is required for the stackable 
bezel. The stackable CNK Jr.’s ship with a flat bezel that drops easily in to the bezel. See Diagram 4 for dimensions. 
CNK321/341/361 – Display Select 
Building upon the 200 series, the 300 series offers the same options but utilizes an extended bezel with built-in, two-button 
illuminated display selection. The display select feature is designed to control the Altinex UT260-052 Under Table HDMI switcher 
making presentations simple and easy to use. However, the display select controls may be used to control other equipment. 
Each CNK321/341/361 user can select which display receives their laptop image. The user selects output 1, output 2, or both 
outputs. The combination of CNK321/341/361 with UT260-052 provides an exceptional collaborative presentation environment 
where up to 5 individuals can present ideas and data using a single set of shared LCD panels or other display devices.

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 
cables 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 from the 
Cable Nook Jr. Remember, the devices plugged into the AC 
power connectors should not draw more than 12A AC. 
 
CNK321/341/361 ONLY 
7.3 Output/Display Select 
Connect the Display Select cable with terminal block connector 
to the input of the UT260-052 Under-Table Switcher. 
The UT260-052 can be configured for various modes of 
operations. The output-select buttons behave differently 
depending on the precise configuration. In the default 
configuration, the output-select buttons have the following 
behavior: 
CNK321 with No Video Signal Applied: 
Pressing either output select button wakes up the system up, 
turns on the display, and then directs the video from Input 6 
(internal media player) to all outputs. Input 6 is typically used 
for a logo, screensaver, or demonstration video. 
CNK321 with Video Signal Applied: 
As soon as the UT260-052 detects a video signal, the system 
wakes up, turns on the display, and switches Input 6 (internal 
media player) to all outputs. Input 6 is typically used for a logo, 
screensaver, or demonstration video.  
Press Output Select 1 button to direct the audio and video from 
the CNK321/341/361 to Outputs 1. Press the Output Select 1 
button a second time while its LED is on to switch the input 
from the CNK Jr. back to Input 6 on the UT260-052. Output 
Select 2 operates the same except it directs the audio and 
video to Output 2.

8. Troubleshooting Guide
Warning 
Make sure no cable or power cord is damaged or pinched. If there has been damage, do not use 
the Cable Nook Jr. Please call the Altinex Customer Service at (714) 990-2300 for repair. 
 
The Cable Nook Jr. supplied was carefully tested and no problems were detected. However, we would like to offer the following 
suggestions: 
 
  CNK321/341/361 
Symptom Resolution 
No Display on 
Projector 
  or Monitor 
1. Check the source and make sure there is a signal present. 
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 and the correct codes 
have been selected. 
3. Make sure the correct input is selected at the CNK Jr. 
Poor Output Image 
1. The source resolution may not be compatible with the display device. Try other resolutions from 
the source. 
2. The source and display may not be compatible. Connect the source directly to the input of the 
display device. If the image is poor the devices may be 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 selected source. Make sure the last selected 
source has audio playing. 
4. Increase the source volume.  
5.  Some audio sources require amplification to be heard on overhead speakers. Check the audio 
level and make sure the source level is compatible with the speakers.
