IF Unit
The IF unit installs between the processor unit and the transceiver unit. Connect the
cables according to the diagram inscribed on the shield cover of the IF unit. JIS cables
and FURUNO cables are available for the connection. To connect the JIS cables, use
the larger cable holes as shown below.
Connect the processor unit earth to the ship's earth with a ground cable (IV-2sq.,
local supply).
Select a location that provides the maintenance space prescribed in the outline
drawing. Follow the compass safety distance in the "SAFETY INSTRUCTIONS" to
prevent interference to a magnetic compass.

How to fabricate the cables
Wrap the drain wire around the outer sheath and secure it with
insulated tape. Secure the sheaths and cable jacket with vinyl tape.
Wrap braided shield around vinyl sheath.
Cover braided shield with conductive fabric tape.
Retrofitting
When retrofitting units such as the FSV-30, the cables from the IF unit to the
Transceiver can be substituted with 10S1258 cables. Check the cables are twisted
pairs and each pin signal is correctly wired. Clamp the cable shields to the respective
unit's cable clamps. Make sure the cables are not bent or damaged.
