5. Turn on the power to the CS-228.
Note: When you turn the unit On, it undergoes a Power On Self Test. If there is a
problem, the On Line Port LEDs flash repeatedly according to a pattern that
indicates what the problem is:
Pattern Indication
On Line LEDs 1 - 8 Flash Simultaneously Internal RAM Memory Error
On Line LEDs 1 - 8 Flash One After the Other External RAM Memory Error
On Line LED pairs 1+2, 3+4, 5+6, and 7+8 Flash
One After the Other ROM Test Error
If any of these problems occur, turn the Switch Off, then turn it On again.
6. Plug in the power cords and power On all the computers.
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.
