Noland Engineering RS11 v3.0 Manual page 11

Programming Example
An example will demonstrate how to configure the RS11. Connect the Unit to a powered CANbus or power injection adapter.
Also connect the device to a PC using the supplied 9-pin Serial Cable. If necessary, a USB-Serial Adapter (not included)
may be used. On the PC, open a Terminal window and set it to match the following:
Baud rate
Data bits
Stop bits
Parity
Flow Control
The Terminal program should be set to send characters as soon as typed. You should not need to hit 'ENTER' to send the
command. You are now ready to send a command. If the device is currently receiving data, you can stop the data flow by
typing
@<
This causes the data flow to stop. If not, your command was either not sent or it was typed incorrectly. You made need to
change your Terminal Program settings. If you now type
@?
You will get a list of the current configuration settings as well as a list of commands/options.
Instance setup
Assume we now want to change an Instance ID. By typing
@I2 or @i2 and @I3 or @i3
the Port or Stbd Instances id would change to 2 and 3 respectively. Note that both lower and uppercase commands are valid.
To confirm the change, type another '@?' and look for the Instance ID's at the end of the first line as shown below.
It will remain configured this way unless it is reconfigured sometime in the future. To verify the configuration change was
accepted, we can again type "@?" which will show
RPM setup
To calibrate RPM, you must have the RPM message enabled. This can de done with the command
@P _ _ _ or @p _ _ _ (Port RPM),
@S _ _ _ or @s _ _ _ (Stbd RPM)
where the 3 dashes represent the ppr value for your engine(s). Assuming we have a V8 engine with a tach signal derived
from Ignition Coil pulses, the ppr will likely be 4 so the command is
@P004 or @p004
for the Port (or single) Engine. The same command with the 'P' replaced by 'S' or 's' will set the Starboard Engine ppr. If
you do not know the engines' ppr, you can keep entering different values and resetting the unit by typing
@ >
This restarts the unit with your new settings. You can view the "$ERRPM,.." sentence in your Terminal window to see if the
RPM is reading correctly. This trial-and-error procedure may be needed for most diesel engines with alternator tach signals
or flywheel inductive pickups. To turn off Port or Stbd RPM enter a ppr value of '000'.
