Sensor Adapters - Furuno VR-7000 Installation Manual

Sensor Adapters

A maximum of eight MC-3000S can be connected to a sensor network. The MC-
3000S can connect max. 10 sensor adapters using the MC1.5-W cables. The maxi-
mum number of MC-3010A units is five.
When fabricating the MC1.5-W cables, use the rod terminal (ferrule type, supplied) to
maintain performance. This fabrication requires the optional crimping tool (type:
CRIMPFOX 10S).
For how to attach the rod terminal and the relations between the connectors and rod
terminals, see "ROD TERMINALS" on page AP-7. Also, the stickers attached on the
reverse side of the covers show the detailed connections.
Note 1: Use the MC1.5-W cable between the sensor adapters.
Note 2: The total length of the MC1.5-W cables should be less than 6 m to prevent
malfunction.
2.8.1 MC-3000S connections
Unfasten four screws to remove the cover, pass the cables through the clamps and
attach the cables to respective connectors. The shield part of the cable (or drain wire)
must be fastened by (connected to) the clamp. For fabrication of the cables connected
to the unit, see appendix 2.
Note: Fasten the cable shield with the cable clamp.
