Sequence #3:
If both RDD100 and transducer are operating normally before an over/under-range condition is detected, the
RDD100 will continue to display the valid last reading prior to the error condition. The error LED will not be lit.

RDD100 Connections
(1) This cable allows a personal computer, with suitable software, to communicate through the RDD-100 to the transducer.
Data can be logged and transducer parameters set/reviewed. Length of cable can be chosen when the RDD100 is ordered.
(At the PC, USB to RS-232 converters can be used.)
(2) Separate cables are available for transducers with Metal or Plastic electrical connectors.
Standard cable length is 6 feet (1.8 m). Connectors may be purchased from Honeywell to construct custom-length cables.
Due to RS-232 limitations, recommended maximum length is 50 ft (15 m).
(3) 12 VDC plug is 2.1 x 5.5 x 10 mm (I.D. x O.D. x length)
Center pin may be either positive or negative polarity.
