3 Installation of the RIO 425
This chapter covers installation of the RIO 425.
3.1 Introduction
The RIO 425 is a generator interface. The module can be connected at the generator, or
close to the generator.
Using the two-wire data interface, it communicates its measured data to a DCU in the
Auto-Maskin Marine Pro range.
The unit can also be used standalone and communicate its data on the inbuilt Modbus
interface.

3.4 Wiring
The RIO 425 has these main connections
● AC Power Supply
● Communication to the DCU
● Generator voltage interface
● Generator current interface
When properly connected and communicating to the DCU on the RIO link, the DCU will
automatically detect the RIO 425 and add an instrument page similar to the one below.
3.4.1 Power Supply
On the RIO 425, connect an AC power supply to terminals A1 and A2.
The supply shall be in the range 100 – 240 VAC (+/- 10%).
Power Supply Fuse
The RIO 425 module shall be protected with an external 2 A fuse on the supply line.
Wire Requirement
Supply wires shall have a minimum area of 1mm2(~17 AWG).
Page 5 (11)

3.4.2 Communication to the DCU
The RIO 425 comes preconfigured to communicate with the DCU 410E/408E or DCU
210E/208E in the Auto-Maskin Marine Pro range.
It can be used together with other RIO expansion modules on the same RIO link.
Only one RIO 425 can be used on a RIO link.
Communication Wiring
Depending on the DCU model connect the wires in the shielded communication cable to the
terminals as shown in the table below:
RIO 425
DCU 410E / DCU 408E
DCU 210E / DCU 208E
S (Shield)
57 (Shield)
B (L)
58 (L)
C1.5 (L)
A (H)
59 (H)
C1.6 (H)
Do not connect the cable shield at both ends.
To minimize the effect of external noise it is recommended to use twisted pair wires.
Communication Bus Termination Resistor
The 120 ohm (1/4 W) termination resistor shall be connected at the last RIO unit (furthest
away from the DCU) in the RIO link chain.
If the RIO 425 is the only unit on the RIO link, then the termination resistor shall be
connected at the RIO 425.
Connect the resistor directly across terminals A and B on the RIO 425.
If the RIO 425 is not the last RIO unit on the link, then the termination resistor shall not be
connected to the RIO 425, but at the last RIO unit on the RIO link.
If there are
several units
attached to the
link add the 120
Ohm resistor
together with the
last unit on the
bus.
Page 6 (11)

The DCU has an inbuilt termination resistor at its end.
When the bus is properly connected, the measured impedance between bus terminals A and
B shall be 60 ohm (+/- 5 ohm).
Wire Requirement
Wires shall have a minimum area of 1.0 mm2(16 AWG).
3.4.3 Generator Current Interface
Connect the generator current interface as follows:
Phase
Current Transformer
RIO 425 Terminal
L1
S1
S2
1
2
L2
S1
S2
3
4
L3
S1
S2
5
6
If only one phase is to be monitored, it is sufficient to connect the desired phase terminals.
Wire Requirement
The wire area shall be minimum 2.5 mm2(12 AWG).
3.5 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.
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.
3.5.1 Configuration from the DCU Web Server
Log into the DCU, and then select Home and then RIO 425.
Set the desired values and press the Submit button.

3.5.2 Configuration using the RIO 425 User Interface
The RIO 425 can be configured using the small push buttons and display on the front of the
unit.
Initiate Configuration
To enter the configuration menu press the key for 3 seconds.
If the icon appears on the configuration screen, the configuration parameters can be
edited.
If the icon appears, the configuration of the unit will be locked with a password. If the
configuration is locked the user must enter the password to unlock.
Press the key to modify the value of the flashing digit.
When the desired value is shown on the screen, use the and keys to move the
edit cursor.
To validate the password, press the key if you are on the last digit or the key if
you are on the first digit.
Default password: 1234
The configuration parameters can be modified after entering the correct password.
Voltage Transformer Primary value
This value shall conform to the phase-phase voltage in the installation. The setting
is important even if there is no voltage transformer in the installation.
Page 8 (11)

Press the key to modify the value of the flashing digit.
When the desired value is shown on the screen, use the and keys to move the
edit cursor.
To validate the value, press the key for 3 seconds; the prog icon will stop flashing.
If the value entered by the user is out of the range of programming values, the programmed
value will be deleted and the system will restore it to the last saved value.
Maximum programming value: 99999
Minimum programming value: 1
Voltage ratio ≤ 1000
Voltage ratio x Current ratio ≤ 300000
The ratio is the relation between the primary and the secondary.
Press key to access the next programming step.
Voltage Transformer Secondary value
If there is no voltage transformer in the installation, then the secondary value shall
be equal to the primary value.
Press the key to modify the value of the flashing digit.

Current Transformer Secondary value
The RIO 425 comes preset to a transformer ratio of 5:1, meaning the secondary
current varies up to 5A. If necessary, the ratio can be changed to 1:1.
Voltage ratio x Current ratio ≤ 300000.
Use the key to browse the available options: 1A or 5A.
To validate the value, press the key for 3 seconds; the prog icon will stop flashing.
