Daisy Chaining
To control even more computers, up to 31 additional switches can be daisy 
chained down from the first unit. As many as 512 computers can be controlled 
from a single console in a complete installation. A table showing the relation 
between the number of computers and the number of KH0116 units needed to 
control them is provided on p. 49 of the Appendix.
To set up a daisy chained installation, first make sure that the power to all the 
devices you will be connecting up has been turned off, then refer to the diagram 
on p. 12 as you perform the steps listed below.
1. Use a daisy chain cable set (described in the Cables section, p. 4), to 
connect the Chain Out port of the parent KH0116 unit to the Chain In port 
of the child KH0116 unit (First Station Out to Second Station In, Second 
Station Out to Third Station In, etc.).
Note: You cannot use the Chain In port of the First Station KH0116, since 
it is the highest level parent.
2. Use KVM cable sets (described in the Cables section, p. 4), to connect any 
available KH0116 Computer Port to the Keyboard, Video and Mouse ports 
of the computers you are installing.
3. Plug the female end of the power cord into the KH0116's Power Socket; 
plug the male end into an AC power source.
4. Repeat the above steps for any additional KH0116 units you wish to add to 
the chain.
5. Power up the installation according to the following procedure:
a) Power on the First Station.
Wait for the unit to ascertain its Station ID and display it on the Station 
ID LED. (The Station ID for the First Stage unit is 01, the ID for the 
Second Stage unit is 02, the ID for the Third Stage unit is 03, etc.). 
b) Power on each Station on the installation in turn (Second Station, then 
Third Station, then Fourth, etc.).
In each case, wait for the Station ID to be ascertained and displayed on 
the current Station before powering on the next one.
c) After all the Stations are up, power on the computers.
