Introduction This addendum to the LD-232, LD-485 and LD-CL manual contains information for the installation and operation using the arithmetic mode ARtH or the wind monitor mode NMEA. The display will accept inputs from RS232, RS485, RS422 or serial current loop inputs (input type is factory configured). The two modes covered by this addendum are detailed below.
Electrical installation Electrical installation The display is designed for continuous operation and no power switch is fitted to the unit. It is rec- ommended that an external switch and fuse be provided to allow the unit to be removed for servicing. The terminal blocks are plug in screw type for ease of installation and allow for wires of up to 1.5mm (2.5mm for relay, AC or isolated DC supply connections) to be fitted.

Wind speed and direction NMEA mode This chapter deals specifically with the NMEA (National Marine Elecronics Association) mode of opera- tion. When used in this mode the display must be connected to a wind sensor with NMEA output such as model WS-MMW-005 solid state wind speed and direction sensor and the RM4 CodE function must be set to NMEA.
