Furuno FAR-2137S - Chapter 7. Block Description

7.1 Overview
7-1
7.1 Overview
The standard supply units are comprised of Processor unit, Monitor unit, Control unit
and Antenna unit (TR unit). Serial signals are used as control signals between each unit.
The ARPA and video plotter functions are incorporated in the SPU board as standard
and a performance monitor is integrated into the Antenna unit as an option. The inter
switch function operates via LAN connection.
7.1.1 Interface
The communication between TR unit and Processor unit is made via RS-422/115.2 kbps,
and the communication between Processor unit and Control unit via RS-422/19.2 kbps,
both using an asynchronous communication method.
The LAN ports of 100 Base-Tx allows the connection with CU-200 or radars of FAR
series. The connection via HUB-100 allows the connection with up to eight FAR-series
radars and up to two CU-200 units. (Maximum 8 ports)
INS (ECDIS) supports both LAN and serial port (RS-422/4800 bps) connection. See
page.6-13 for details of interface of each port.
Fig. 7.1.1 Example of the Interface between units.
