Please note that the following conditions apply when operating the True Loop Emulator
system is this way:
 The Interface will not be able to run Scripts on its own.
 The Interface must have a constant supply of power. If the power supply is
interrupted, the Interface will lose the settings it has been programmed with, the PC
will need to be reconnected, and the Interface re-configured.
 The Interface cannot store any data and therefore the PC cannot be reconnected to
retrieve events or data logs that occurred whilst it was disconnected.
 The analogue ramping function does not work without the PC connected.
