Preliminary Operations
a)
Select the location of Display 09 on the ECU and verify the position of the Dip Switch 4 indicated in the top left of the display
with the caption Sw.4=ON/OFF.
b)
If the position of the Dip Switch 4 is ON, it is necessary to change it to OFF following below procedures:
•
Switch off the ECU (Disconnect the primary power and any power supply coming from the back-up power supply system
if present)
•
Using the appropriate screwdriver remove the four screws used to block the metal protection of the electronic board
connecting the signal cables (terminal block board placed at the bottom of the cabinet containing the ECU)
•
Once the metal protection has been removed, move the Dip Switch 4 to the OFF position (Downwards) then switch on
the ECU again

f)
Connect a "Straight" Serial Cable Male-Female
between the serial port of the PC and the serial port
placed at the bottom right of the Front Panel of the ECU
(COM Port 1). If the PC does not have a dedicated
serial port use an USB / Rs-232 adapter and proceed
with the installation of the drivers necessary for correct
operation.
g)
Check the PC for the "Number" of the serial port "COM"
being used for the connection; in order to do this, go to
"Devices Setup" in Windows, expand the item "COM –
LPT Port", then verify the "Number/Name" of the serial
ports available on the system.
When using an USB/Rs‑232 converter it is
possible that a high COM port "Number"
(above 5) was assigned to it; in this case it
is necessary to modify the allocation in field
1 – 5; in order to do this verify the functions
included in the installation driver of the
converter itself.

h)
Launch the DosaLink software, check that the Station
in operation is already present in the grid (the User
Code - Number must be identical to that at loc:03 of the
ECU to connect), if not it will be necessary to insert a
new Station following the instructions in the DosaLink
software manual.
i)
Check that the type of connection selected on the
column "Modem Number" is "COM X - 19200", where
X stands for the "Number" of the PC serial port on
which the serial cable has been connected; if not, it is
necessary to open the archive of the stations, select the
station to modify, push the button "Edit", then update
the item "Connection Type" stating the communication
port required. In order to "open" the station archive
display, click on the second icon on the upper left part
of the DosaLink display, then proceed with the update
of the "Connection Type".
The following image shows a CORRECT configuration
permitting communication between the Station "DEMO_2"
and the "User Code" 00000002, through the PC Serial Port
COM 1.
