1.2 System Diagram
The figure below shows the system diagram for the RC-1800F/1800T. The RC-1800 series
GMDSS Radio Station consists of two models' RC-1800F (floor deck mount) and 1800T (tabletop
mount). Equipment are controlled using FURUNO’s radio interface protocol called MIF (see
note below).
The type and number of the component differ from set to set.
Note: MIF is a handshaking type signal exchange protocol developed by FURUNO for remote
control of radio equipment. In the RC-1800F/1800T, for example, the DSC-60 can automati-
cally set the frequency on the SSB Radiotelephone.
