Caution: The RayData must be connected to a 12V supply only.
Connect the power supply using the standard power cable supplied, as
follows:
1. Connect the molded power plug to one of the SeaTalk connections
on the rear of the RayData. Run the free end back to the vessel’s
12V DC distribution panel or battery.
2. Cut the cable to length and connect the red wire to 12V and the
screen to 0V. Protect the circuit with a 5A fuse/circuit breaker.
Larger System
If you are using the RayData as part of a larger system, you will need to
use the SeaTalk and/or NMEA connectors. You can still use the directly-
connected depth and speed transducers in this case.
The RayData can be connected to an existing SeaTalk system, using a
standard SeaTalk extension or interface cable connected to the SeaTalk
connectors on the rear of the RayData. The power supply and data are
passed from instrument to instrument via the daisy loom cable, as
shown in the following diagram.
