5.8  Setting a security password 
 

There are many situations where unrestricted access to corporate file servers or sensitive 

information needs to be controlled. In such circumstances, the LINDY CPU Switch can be locked 

away in a room or secure cabinet and controlled remotely. In this mode typing the keyboard 

hotkeys together with 0 will blank the screen, disconnect the keyboard and mouse from all of the 

computers and display ‘P’ on the LINDY CPU Switch display. Control can only be regained by 

typing the correct password on the keyboard. 

To set the password in configure mode, first type 

3

 then <ENTER>. The display on the LINDY 

CPU Switch will change to show ‘=‘ and you can then type your password. The password is not 

case sensitive and can be any combination of key strokes, including the function keys, but 

excluding the 

t

 ,

s

 , 

u

 and <ENTER> keys. When you have typed in your password type 

<ENTER> to register it in the stored memory. Do not worry if you type the password incorrectly, 

you can always re-enter configure mode and set the password again. If you have lost the 

password and the LINDY CPU Switch Junior is locked, the unit may be unlocked by powering 

down the LINDY CPU Switch Junior, entering configure mode at power on (see section 5.1) and 

performing a complete reset using the 

I

 function. 

NOTE - The password consists of a combination of key strokes rather like the code to a safe. The 

key strokes are not case sensitive and can include all the keys on the keyboard (except 

t

 , 

s

 , 

u

 and <ENTER>). Consequently the following 'password' would be valid:  

e)5('

5.9  Cascade query code 

The LINDY CPU Switch Junior OSD use a special ‘query code’ to detect whether or not they are 
connected to another LINDY CPU Switch Junior. By default your LINDY CPU Switch Junior OSD 
uses query code AD. Another range of switches, LINDY CPU Switch Pro with firmware versions 
less than 1.09 used query code EF. This was found to conflict with a small number of other (rare) 
devices that used the same query code so an alternative query code was provided to ensure 
compatibility. Either query code may be used but you should make sure that all cascaded LINDY 
CPU Switches are set to use the same query code. If any of the cascaded LINDY CPU Switch 
Pros have firmware versions less than 1.09 then the cascade query code for all the LINDY CPU 
Switch Juniors and LINDY CPU Switch Pros should be set to EF.
