When the logic output is set low (off), the transistor will turn off and an open
circuit will be created between the logic output and the chassis ground
preventing any flow of current as shown in the following figure.
See Logic Examples for information on how to wire the logic interface for
common logic applications.
Powering Up The System
Connect the AC power line to a grounded AC power main when ready to
power the device and plug the other end securely into the rear of the
SoundStructure unit. Ensure the plug is securely inserted as shown in the
following figure. Upon insertion there will be some initial resistance - continue
pushing until the power cord is plugged in.
The SoundStructure units require an AC voltage supply in the range of 90-250
VAC and 50-60 Hz. Power should be applied after any plug-in cards are
installed.
As there is no power switch on the SoundStructure devices, once power is
connected, the system will begin the boot-up process.
