Section 4 - Operation 

Operation 

Operating the Product 

Self-Test Procedure:  

As product powers-up it performs a self-test procedure. In case of 
self- test failure for any reason, including jammed buttons, the 
product will be Inoperable. Self-test failure will be indicated by the 
following abnormal LED behavior:  

 

All 

channel-select LEDs will be turned 

ON and then OFF; 

 

A specific, predefined LED combination will be turned ON;  

 

The predefined LED combination will indicate the problem 
type (jammed buttons, firmware integrity). 

 
Try to power cycle product. If problem persists please contact your 
system administrator or technical support. 
 
Now that product, computers and peripherals are connected and 
powered up, it is ready for use.  

 
Default Channel 

 

After product boots up, blue LEDs stripe will illuminate and the 
default active channel will be channel #1. This will be indicated by 
white color illumination of  
push-button #1.  

 
Product Mapping to Sources 

 

Product mapping to sources is indicated by stickers/labels specifying 
which channel is mapped to which computer. 

Front Panel Push-Buttons 

Following power up, the default channel is #1.  

The  user  can select  any other  channel by pressing the  appropriate 
front panel push button.  

The  mouse  cursor  will  be  positioned  at  the  center  of  the  selected 
computer display. If computer is connected to multiple displays, the 
cursor will be positioned at the center of the primary display. 

The  currently  selected  channel  is  indicated  by  white  color 
illumination of the appropriate push-button.  

Once  a different channel is selected  -  keyboard, mouse,  and audio 
follow selected channel.  

Keyboard Status Indication 

In  order  to  enhance  usability,  product  provides  keyboard  status 
indications  via  dedicated  LEDs  located  on  product  front  panel.  To 
maintain the required unidirectional connectivity between keyboard 
and product, these indication are not given on the keyboard itself as 
done with non-secure products 

The  keyboard  status  indications  are  given  via  3  LEDs  on  the  front 
panel of the product: 

 

• CL – CAPS Lock 

• SL – SCROLL Lock 

• NL – NUM Lock 

The indications behave the same as the LEDs on the keyboard as if it 
was connected directly to computer. 

Switching  from  channel  to  channel  may  change  the  status  of  the 
LEDs based on the current settings on the computer connected to 
the active channel.
