Chapter 2. Installation and Operation

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.
