Example 2:
Index: 2 in the screenshot above
From the DSE Gencomm protocol document, the following shows the location of the “Fuel Pressure 1”
instrument which is read from the CAN ECU of engines that support this feature.
This is taken from Page 5 – Extended Instrumentation. Therefore the Page parameter is set to “5”.

Offset parameter is
set to match the
first register for the
instrument, in this
case 5.
Sign parameter is set to
Unsigned. This is
identified by the Lack of
the “S” after the number
of bits.
Size is set to 16 bits.
This means that every 1 kPa is stored in
the DSE controller as “1” (ie the DSE
controller records kPa).
When selecting this instrument for
display in the DSEWebNet system,
select “1” for the Scalar parameter to
display it as kPa. Alternatively select
“100” for the Scalar parameter to
display it as Bar (1 bar =100 kPa).
