9.4 Example 4 - 24 Receivers with Multiple Operator Stations
The example in Figure 18 shows a much larger system than the previous
examples. Three CIB modules are used to control a total of 24 receivers. The
three IIB modules can be used to provide control of all receivers from the main
console. Each PC in the system can control all receivers as well. The HIB
modules provide both local and remote control of all receivers. With the HIB
connected directly to the modem, the comparators can be accessed from anywhere
that has a dial-up phone line.

Figure 18 - 24 Receivers with Multiple Operator Stations
Power can be provided to this MCN system from two power supplies, as long as
the network cables are connected properly for power distribution. One supply
could power one HIB module and all three CIB modules. Another supply could
power the other HIB module and the three IIB modules.
This system allows parallel status and control of three comparators from three
operator locations. If an operator at one station force votes a receiver, the other
two operator stations will show that receiver as voted. Or, if an operator at one
station disables a receiver, all other operator stations will also show that receiver
as disabled. If one of the comparators signals that a receiver is voted, all three
stations will show the receiver being voted.
