Item  à Description NMEA 0183-compliant device NMEA 0183 cable Item Garmin Wire Function Power Power ground Data ground RxB (-) RxA (+) Lamp or Horn Connections The device can be used with a lamp, a horn, or both, to sound or flash an alert when the chartplotter displays a message. This is optional, and the alarm wire does not need to be used in order for the device to function normally. When connecting the device to a lamp or horn, observe these considerations. • The alarm circuit switches to a low-voltage state when the alarm sounds. Garmin Wire Color Red Black Black Orange/white White NMEA 0183 Device Wire Function Power Power ground Data ground N/A TxA (+) • The maximum current is 100 mA, and a relay is needed to limit the current from the chartplotter to 100 mA. • To manually toggle visual and audible alerts, you can install single-pole, single-throw switches.

When connecting video input and output sources, observe these considerations. • The eight- and twelve-inch models have two composite-video ports labeled CVBS 1 IN, and CVBS 2 IN. The fifteen-inch models have four composite-video ports labeled CVBS 1 IN, CVBS 2 IN, CVBS 3 IN, and CVBS 4 IN. • The fifteen-inch models have one component-video port labeled COMPONENT IN (480i/576i). ◦ The composite- and component-video ports use BNC connectors. You can use a BNC to RCA adapter to connect a composite-video source with RCA connectors to these ports. ◦ The video from sources connected to these ports is available only for display on the device or additional monitor connected to the device. Composite or component video is not shared across the Garmin Marine Network or NMEA 2000 network. • The fifteen-inch models have one video port labeled DVI-I VIDEO IN that accepts video from digital or analog sources using a DVI-D or DVI-I cable. ◦ If needed, you can use an HDMI to DVI-D converter to connect an HDMI-compatible source to this device. ◦ If needed, you can use a VGA to DVI-I adapter to connect a VGA source to this port. • You can connect a display to the DVI-I VIDEO OUT port to view a mirror image of the screen on a computer monitor or HD TV using a DVI-D or DVI-I cable. ◦ If needed, you can use a DVI-D to HDMI adapter to connect to an HD TV or other HDMI-compatible display. ◦ If needed, you can use a DVI-I to VGA adapter to connect to a computer monitor or other VGA-compatible display. • Although it is recommended to use DVI cables sold by Garmin, high-quality third-party DVI cables may be used. 11
