Multi-box Configurations (-MB Option)

Multi-box configurations are identical to a two or three box system except each chassis (box)
has its own controller. When connected as a multi-chassis system through the system interface,
the controller in the auxiliary chassis is disabled and the entire system is controlled from the
master unit. Operation is identical to a normal multi-box model. E.g. a 9000CS/2-MB is
connected and operated the same way as a 9000CS/2. While a 9000CS/2 will have one
chassis with a blank front panel, a 9000CS/2-MB will have a controller on both front panels of
which only one is used when configured as a 9000CS/2. The other controller will display a
message indicating it is operating as an auxiliary unit
The benefit of the –MB option is that both units can be separated and operated independently.
To so do, proceed as follows:
1. Turn off both units.
2. Disconnect the output terminals (A,B,C, COM) from each other.
3. Disconnect the system interface cable between the two (or three) units.
When powered up, each unit will power up as a stand-alone unit. Connection diagrams for a –
MB system are identical to those for a 9000CS/2 13500CS/3 or 18000CS/4. See section 3.5.3,
Figure 3-3 through Figure 3-5 for wiring diagrams.
3.8.1 Power Up and Power Down sequence.
A multi-box CS system can be turned on in either order. Generally, it is recommended to turn on
the master unit before turning on the auxiliary unit and turn off in the opposite order but no
damage will occur if the order is reversed.
Note: It is not recommended to turn off either unit without turning off the other unit and
then turning it back on. This may result in miscellaneous error messages
occurring on the unit that was not powered down. If one unit has been turned off,
turn off all units first before turning the system back on.
If a master unit is to be used by itself, it is not sufficient to just leave the auxiliary unit off while
the system interface cable remains connected. Disconnect the system interface from the back of
the master unit and then turn the unit on for stand-alone use.

This message will disappear when the controls on the auxiliary unit are operated. However, changing settings on
the auxiliary unit controller will not affect the output. Use the master unit controller and or remote control interface to
operate the system.
