For easer cable routing, the power, NMEA^® 0183, and Garmin^® Marine Network cables are packaged without the locking rings installed. You should route the cables before you install the locking rings.

After connecting a locking ring to a cable, make sure the ring is securely connected and the o-ring is in place so the power or data connection remains secure.

The device should be connected to the same power source as the card reader. If this is not possible, the devices must be connected to the same ground.
