Note: You must turn on the power to the CS-228 before turning on the power to the computers.

Two Stage Installation

To control even more computers, up to eight additional Master View units can be cascaded from the CPU ports of the CS-228. The cascaded Master Views that connect back to the First Stage unit (the CS-228), are considered Second Stage units. As many as 64 computers can be controlled in a complete two stage installation. A table showing the relation between the number of computers and the number of Master View units needed to control them is provided in the Appendix.

Note: 1. Only Master View CS-138A, CS-9138, CS-128A, or CS-124A units can be used with the CS-228;

2. Master Views cannot be cascaded beyond the second stage.

To set up a two stage installation, do the following:

1.Make sure that power to all the devices you will be connecting up, including all preexisting devices on the installation, have been turned off (unplug the power cords of any computers that have the Keyboard Power On function; unplug the First Stage unit).

2.Use a 2L-1601P Custom Cable set (described in the Cables section, p. 3), to connect any available CPU port on the CS-228 (First Stage) unit to the Console Port connectors of the Second Stage unit.

3.Use CS Custom Cable sets (see the Cables section of the Second Stage unit’s user manual for details), to connect any available CPU port on the Second Stage unit to the monitor, keyboard and mouse ports of the computer you are installing.

4.Repeat steps 1 - 3 for any other Second Stage units you wish to connect.

5.Plug in the power adapter cable for the First Stage Master View unit’s Power Jack.

6.For each Second Stage unit, plug the power adapter into an AC source; plug the power adapter cable into the Master View’s Power Jack.
