Activating the Pulse Outputs
The radio clock PC32 generates active high TTL level pulses whenever a second or
minute changes. A jumper block on the board can be used to wire the TTL outputs
(0..5V) to some of the connector pins. In this case, absolute care must be taken if
another device is connected to the port, because voltage levels of -12V through
+12V (as commonly used with RS-232 ports) at TTL outputs may damage the
radio clock.
