Contact Closure

*Note! Pin 9 is used for contact closure input. This pin is not normally used by RS- 232 devices. Some laptop and desktop computer COM ports have been observed to “pull” pin 9 to ground; this will cause unexpected behavior of the contact closure function if pin 9 is not disconnected on the PC end of the cable. If this behavior is observed, make sure that pin 9 is disconnected on the PC end of the cable.
