Instructions, M-611, Software Rev. R.
Connecting Multiple M-611 Units via CAN Connection:
If installing more than one M-611 unit on a vessel, the CAN connection must be utilized so the
M-611 units can communicate with each other. When installed with the CAN connection
(Terminals 37-39 per Drg. 3-6705), the "master" M-611 is connected to installed output devices
(horns, lights), while additional M-611 units are connected only to a power source, and the
"master" M-611 via the CAN connection.
Note: If CAN connection is utilized to wire only M-611s to each other, external of a properly
configured CAN bus, a 120 Ohm resistor must be wired in parallel as a jumper between
terminals 37 and 38 (CAN HIGH and CAN LOW) on each networked M-611 to provide resistance
on this circuit.

2.) Device Setup:
On certain vessels, some of the sound signaling devices such as aft horn, or gong may

and "Gong" button
switch. To re-enable a device, the process is the same. The Date and Time Display will
notify the user when the device is re-enabled. Once the devices that are not included in
the sound signal system have been disabled, the included P546-12 and P546-10 Button
Overlays may be permanently placed over the unused switches, to eliminate them from
view on the keypad. The M-611 is now set up and ready for normal use.
