Termination with MFD
The MFD unit is terminated with a terminator as shown in Fig.23, because the unit does not
have the internal terminator.

Internal Terminator
Furuno CAN bus devices, DRS, FI-50, GP-330B, SC-30, and WS-200 have an internal
terminator, so these devices can be connected to the backbone cable as shown in Fig.24.
By connecting the device to the backbone cable, the cable length between the T-connector
and the device can be extended more than 6 m.

To activate the internal terminator;
(a) DRS
The resistor assembly, 120 OHM-1007#24-L50, C/N: 000-167-746 is connected between
#5 and #6 of J603 in the radome antenna and #4 and #5 of TB102 in the open type
antenna.
