(The following is not specific to the FG|SB system - but generally useful information.)
It used to be, in the "good old days", that switches on monitors were simple mechanical ones: if a power switch was in the ON position, then whenever 120VAC power was applied, the monitor came on. Thus, an entire set of museum exhibits would start up when power to the building was turned on in the morning.
Those days, unfortunately (in this regard anyway), are gone. Now, many monitors have switches that interface to an internal microcontroller. The consequence of this is:
- Some monitors still function in the old way (even if implemented by new methods).
- Some monitors will start on application of AC power only if you build a mechanical fixture to hold the power button in always.
- Most horribly, some monitors require a momentary press to start them up after an AC power cycle.
If you have A/V systems integrators installing exhibits, they are the ones to address this and will likely be familiar with this issue.
