NOTE: The signals on pins 1, 3, 4, 6, 9 and 10 each have an open collector output. Thes pins normally
measure + .07V maximum when a true condition exists. If a false condition occurs, the voltage will drop to
0V. To achieve a signal level of +5V, you must add a 330 ohm, 1/4 W pull-up resistor between the open
collector output pin and Vcc (pin 13) as illustrated. This will provide a signal level of +5V for a true
condition and 0V when a false condition exists. The maximum voltage that can be applied to these pins is
+50V and the maximum current they can sink is 500 milliamps.
