CONNECTOR PIN EXPLANATION
PD-6130 Series
(Caution) The operating voltages specified below are used in common irrespective of the presence of signals. In this case, how-
ever, part of the operating voltages (red characters) may change according to the signal conditions when the main
power supply is turned on (POWER button ON).
Status of LED lighting:
v
for lighting in green,
vv
for unlighting, and
vvv
for lighting in red.
