This instrument operates from a single-phase power source with one current-car-
rying conductor at or near earth-ground (the neutral conductor). Only the line
conductor is fused for over-current protection. The mains frequency is 50 or
60 Hz. The operating voltage range is continuous from 100 to 240 VAC.
Note that the instrument does not have a power-switch. When you connect the
power cable to the AC voltage line, the instrument powers on.
The two Parallel Input connectors accept signals which comply with the
SMPTE 260M/274M/296M standard:

The Serial Out 1/2 connector outputs two identical converted serial digital signals

Inspection and cleaning are preventive maintenance procedures. When done
regularly, preventive maintenance may prevent converter malfunction and
enhance reliability.
