Resumen del manual
The instructions for connecting data cables and setting up the communications port appear in this addendum. NMEA 0183 Data Cable Connections NMEA is a standard communications format for marine electronic equipment. The Cuda 240i can send information to any device that receives NMEA 0183 data. This allows the unit to work with VHF marine radios equipped with the Digital Selective Calling (DSC) distress call feature. To send NMEA 0183 data, the Cuda 240i has one NMEA 0183 version 2.0 communication port. The com port can be used to send NMEA formatted data such as your current position. The provided Cuda 240i data cable plugs into the accessory socket on the right side of the back of your unit's case. The data cable ends in two wires that connect to your VHF radio or other NMEA device. The Cuda 240i uses the yellow wire to transmit and the black shield wire for signal ground. NOTE: Some VHF radios, such as the popular Uniden. brand, have input levels which require use of an additional diode and resistor built into the Cuda 240i data cable. This is Wiring Diagram A, which is described on page 2. The majority of the DSC radios will work with the resistor and diode as provided by Eagle. 1 A few other radio brands (and other electronic devices) that meet the NMEA 0183 standard won't need these adapters and you will have to remove the resistor and diode to make those work. This is Wiring Diagram B, which is described on page 4. A few other radio brands (and other electronic devices) that meet the NMEA 0183 standard won't need these adapters and you will have to remove the resistor and diode to make those work. This is Wiring Diagram B, which is described on page 4. Recommended Tools and supplies Recommended tools for this job include: wire pliers or wire stripper and a wire cutter. Required supplies for this job include: two gray (18 gauge) or blue (16 gauge) wire nuts and electrical tape. Supplies are not included. Wiring Diagram "A" Begin by stripping the wire ends of the device you're connecting to the Cuda 240i. (You'll notice the Cuda 240i's data cable comes pre-stripped, with wire ends exposed.) Use a pair of wire pliers to strip about 1/4-inch (6.35 mm) of insulation from each of the radio's or other device's data wires. Strip the ends of the VHF radio's data wires. Connect them to the pre- stripped wires of the Cuda 240i's data cable (shown right). 2 Twist the exposed wires together as shown in the following figures. If you're using a Uniden or similar radio, connect the radio's NMEA Wire to the Cuda 240i data cable's yellow wire, and the radio's Ground/Shield wire to the Cuda 240i data cable's black shield wire. If you're using another radio brand or NMEA device, see Wiring Diagram B instructions at the end of page 3. NMEA Wire (Receive) or NMEA + Twist the exposed wires together as shown in the following figures. If you're using a Uniden or similar radio, connect the radio's NMEA Wire to the Cuda 240i data cable's yellow wire, and the radio's Ground/Shield wire to the Cuda 240i data cable's black shield wire. If you're using another radio brand or NMEA device, see Wiring Diagram B instructions at the end of page 3. NMEA Wire (Receive) or NMEA + Com port to Cuda 240i Shield (Ground) Ground/Shield or NMEA – To Uniden radio or other device Com port wiring to transmit NMEA information to a Uniden or similar VHF radio or other device. Twist the appropriate wires together, making sure that the exposed ends make good contact. Secure the wire ends with wire nuts, then wrap each wire nut securely with electrical tape to protect against moisture, as shown in the figure on the right. 3 Wiring Diagram "B" If your VHF radio or other device requires true RS-232, you will need to remove the diode and resistor built into the end of the Cuda 240i data cable. You will notice near the end of the cable a segment protected with black heat-shrink. To connect the Cuda 240i to a true RS-232 radio, first remove the Uniden adapter segment of the cable as shown in the following figures. For Wiring Diagram B installations, remove the Uniden adapter segment at the end of your data cable as shown at left. Snip off the end of the cable protected by the black heat-shrink. At right, we have used clear heat-shrink for clarity, so you can see the diode and resistor protected within. Remove this portion of the cable. 4 After you've removed the adapter segment, use wire pliers to expose the ends of the five remaining wires in the cable. Cut off the black, blue and white wires, then seal their ends with electrical tape. Blue White Cut black, blue and white.
