VS300 Pre-installation Manual Planning for control and monitoringPage 8-4 Issue 2.0 2010-12-01Table 8.1: Factory Defined Digital InputsDigital outputsUp to 16 digital outputs, that indicate either the presence of various alarms or the status of operatorcontrolled circuits, are available for remote monitoring on the REMOTE I/O-B D-sub connector(A1J2B) on the rear of the transmitter. The sources and active logic levels of these digital outputs arepreset at Nautel, but are also user-configurable. See Table 8.2 on page 8-5 for a list of the factorypreset outputs, their descriptions and their associated pins on the REMOTE I/O-B connector (A1J2B).A switching device for each digital output, configurable through the front panel UI, provides thedesired active logic when a true condition exists.For example, if a digital output is configured as Output Low When On (see the VS300 Operations andMaintenance Manual for the specific text displayed on the UI), then the digital output’s switching circuitwill provide a current-sink-to-ground when a logic true condition exists and an open collector for alogic false condition.Digital Input Function Input Pin1.
