Alarming Capability

The SMX SeaView digital displays have 100% full audio/visual alarming capability. In addition, an external lead can be used that will close an external alarming circuit allowing for the use of externally driven alarm devices such as buzzers, lamps, ect. This will allow the operator to trigger an external existing alarm circuit when the SeaView experiences a engine/gear fault event. For example, if a vessel is already configured with a flow alarm and/or thermal sensing alarm circuit which is indicated by a buzzer/light at the dash, the SeaView alarm output wire can be “tied” into that circuit to indicate an alarm on BOTH the SeaView device and the external buzzer/light circuit. The lead that drives an external alarm is located on PIN 3 of the grey “A” connector on the back of the display unit. This lead will close to ground when an alarm is experienced. If using a 5-pin Bosch style relay, wire one end of the coil to switched 12V+, and use the external alarm lead as the coil NEG. All alarms are saved in the devices alarm panel and can be referenced at a later date.

NMEA Gateway Capabilities

The SMX DigitalView™ Mechanical Engine Digital Display can be fully integrated with robust NMEA 2000 input and output (I/O) features that will allow you to fully display engine operating parameters on your exisiting NMEA 2000 compatible devices such as plotters, GPS, and more.
