Addendum I
Additional Instructions for
Cuda 250 & Cuda 250i S/Map
The Cuda 250 contains a communications port for NMEA 0183 output.
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 250 can send information to any device that
receives NMEA 0183 data.

- Page 1 Pub. 988-0152-082 Addendum I Additional Instructions for Cuda 250 & Cuda 250i S/Map The Cuda 250 contains a communications port for NMEA 0183 output. 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.
- Page 2 Cuda 250 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. 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.
- Page 3 Wiring Diagram "A" Begin by stripping the wire ends of the device you're connecting to the Cuda 250. (You'll notice the Cuda 250 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.
- Page 4 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. After taping the wire ends individually, wrap the entire connection with electrical tape as shown.
- Page 5 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.
- Page 6 When the data cable is connected to your VHF radio, all you have to do is plug it into the sonar/GPS unit. Attach the data cable's plug to the accessory socket on the right side of the back of your unit's case.
