Pin description of the RS-485 connector to HOST interface
The indicated colors above apply to the standard yellow 8 wire cable as used for the SMP pyranometers (with 8 pin Binder 712
connector). To use this port as 2 wire RS-485, connect the RD+ and TD+ together (as D+) and the RD- and TD- together (as D-) and
select in the webpage under system configuration/ Communication / Transmission, the 2-wire option. This switches local echo off.
6.3 Serial interface, AUX in port
