Add the following Digital Clock text for LED Clock Series
1532A:
DIGITAL CLOCK THEORY OF OPERATION
General
The digital clock is a solid-state 24 hour clock with a
seven segment LED (light emitting diode) display. It
indicates time in hours, minutes and seconds in synchro­
nism with the 5065A generated 1 PPS signal. Time may
be set and synchronized using the HOLD/SLOW/FAST
pushbuttons of the LED clock.
The required inputs which enable the lock to operate
are connected to the clock by five wires. These are:
1. Unregulated +28 Vdc from the 5065A used to
generate a regulated +5 Vdc and used exclusively
to drive the display.
