Installation Manual - RIO 425 

 

 

Is the DCU communicating 
with the RIO 425? 

 
This can be verified in the DCU web 
server or user interface under the 
Troubleshooting menu. See the RIO 
425 section. 
There is a comm LED indication on the 
RIO 425 that flashes when 
communicating.

Configuration 

The RIO 425 can be configured from 
the web server on a DCU in the Auto-
Maskin Marine Pro range. This is the 
easiest and preferred method. 
If no such DCU is available, the RIO 
425 can be configured using the user 
interface on the front of the unit. 

Note! The current transformer ratio is 
pre-configured to 5:1. It is possible to 
change this ratio to 1:1, but only using 
the RIO 425 user interface.
