When used with the DCU 200 Series, connect the same power supply to the RIO
410/210 as used to supply the DCU 200 Series.
Terminator Resistor
The 120 ohm terminator resistor shall be connected at the last RIO unit (furthest away from
the DCU) in the RIO link chain.
If the RIO 410/210 is the only unit on the RIO link, the terminator resistor shall be connected
at this RIO 410/210. If so, connect the resistor directly across terminal 64 (L) and 65 (H) on
the RIO 410/210.
There shall be one
terminator resistor only on the RIO link. The DCU has a built-in
terminator resistor at its end, so no terminator resistor shall be added on the DCU
side.
Is the DCU communicating with the RIO?
This can be verified in the DCU web interface under the following section:
Home –> Troubleshooting -> DCU -> Communication.
Locate the RIO 410/210 line.
DCU Configuration
When properly connected, the DCU will find the RIO automatically (plug and play). However,
the DCU configuration shall be updated to include the connected RIO.
If the RIO is not detected at a later stage because of a fault, then the DCU will indicate this
with a warning.
If a RIO is removed from the application, then it must be manually removed from
the configuration, otherwise the DCU will keep looking for it and indicate with a
warning.
3.3 Configuration
All RIO channels are configured using the DCU Engine Controller web interface. The RIO
does not store any I/O configuration internally.
Additional configuration information of the RIO can be found in the DCU Configuration
Manual.
4 Schematic
In the drawing below “RIO 410” can be either RIO 410 or RIO 210, and “DCU 410” can be
any DCU in the Marine Pro family.
