Additional Instructions for
Eagle Cuda 240i S/GPS
Your sonar/GPS unit, the Cuda 240i, functions exactly like the Cuda
240 described in the manual provided (part 988-0152-012). In addition,
the Cuda 240i 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 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
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.

- Page 2 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. Consult your other device's owner’s manual, then read through all of the following instructions before you begin.
- Page 3 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.
- Page 4 After taping the wire ends individually, wrap the entire connection with electrical tape as shown. This will help protect from moisture and prevent the wires from breaking contact. 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.
- Page 5 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.
