gram most suited to your brand of radio or other device. If your device manual indicates an RS-232 connection (i.e., a computer), remove the resistor and diode and connect using Wiring Diagram B. Most other connection types (TTL; NMEA + and NMEA –; differential) will re- quire Wiring Diagram A.

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 M68i. (You'll notice the M68i'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 M68i's data cable (shown right).

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 M68i data cable's yellow wire, and the radio's Ground/Shield wire to the M68i 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.
