Patent applied for GB2424280
As part of the MurphyLink® family, CANdrive offers a cost
effective instrument solution for modern electronic engines.
CANdrive modules read engine ECU CANbus/J1939 data,
drive standard electric panel gauges, and provide LED
indication of status and faults.
CANdrive has three dedicated outputs for tachometer, oil
pressure and coolant temperature gauges, with DIP switchselectable compatibility for Murphy, VDO or Datcon gauges.
For volume orders, the outputs can be custom-configured for
other gauge types, lamps, relays or remote signalling.
CANdrive advantages include:
x
the retrofitting of existing electric gauge panels to new,
J1939 compatible engines
x
the use of standard, economical electric gauges with
new J1939 engines
x
no need for installation of additional gauge senders,
tachometer magnetic pickups and wiring.
CANdrive is packaged in a compact, surface mounted
case with epoxy encapsulation for maximum durability
and environmental sealing. Electrical connection is via a
12-way automotive type connector. Model CDV100F has
a forward facing connector and one power/CAN status
LED. Model CDV300R has 8 LEDs for indication of
J1939-transmitted engine faults and status. All models
include a 6-way DIP switch for flexible configuration.

Panel Installation
CANdrive modules are surface-mounted with 4 x no.4 screws, fixing centre dimensions as
shown. Select screw length according to panel thickness, ensuring a maximum of 13mm
(½ inch) screw depth into the CANdrive fixing holes.
Dimensions
mm (in.)
Model CDV100F, with forward facing connector, is designed for surface mounting inside
an enclosed panel. Model CDV300F, with 8 LED indicators and rearward facing connector,
is designed for front-of-panel mounting: this module requires an additional 60 x 40mm
(2.4 x 1.6 in.) panel cut-out for rear access to connector and switches. A CDV300F with
optional gasket CDVG (fitted into a well behind the case rim) provides IP65 front-of-panel
environmental sealing.
Before installing, ensure that the final mounting location meets operating temperature and
environmental sealing requirements, and allows access for:
a) connection of the wiring harness
b) configuration of DIP switches S1 to S5 (location as shown above right). Alternatively,
set these switches before panel fixing – see Configuration section below for full details.
Configuration
DIP switches S1 to S5 allow OEM- or user-configuration of
CANdrive operating options. Switch S6 is not used. CANdrive
is supplied with all switches in the ON (up) position.
Switch settings must be made as appropriate, according to
the configuration table right. Adjustment of the switch
positions must be made while CANdrive is powered down.

Electrical Connection
CANdrive electrical connection is via a 12way automotive type receptacle shown right.
CANdrive models are available with the
connector facing forward through the front
label (‘F’ option, e.g. model CDV100F), or
rearward through the epoxy encapsulation
(‘R’ option, e.g. model CDV300R).

Pin 7 gives a square wave output (0V to battery positive
DC), with a frequency proportional to engine speed.
At 1500 RPM engine speed, the output frequency is
119 Hz (±1%), suitable for driving charge alternator
based tachometers such as the Murphy ATA and ATHA
series. Pin 7 gives no output when engine speed is
below 100 RPM.
An 8-way, 30”/270mm wiring harness is available as
an additional loose item or as part of a CANdrive kit.
For customer-made harnesses, part numbers for the
mating connector plug and pins are as follows:

Connect each output to the appropriate gauge/
tachometer signal input. Connect gauge/tachometer
negative terminals to battery negative, ideally via
dedicated wiring to terminal 3. (The use of dedicated
return wiring to pin 3, rather than a ground/earth return,
minimises gauge inaccuracies caused by ground noise.)

Connect these terminals to the engine CANbus, taking
care to observe the correct polarity. The CANbus cable
shield/screen is typically connected to ground/earth at
one end only (often at the ECU): refer to the engine
manufacturer’s installation guidelines.

CANbus J1939 specifications require two 120 Ohm
terminating resistors at each end of the network.
CANdrive is supplied with a 120 Ohm network
terminating resistor in circuit. If CANdrive is not
positioned at the end of the CANbus network, switch
out the terminating resistor by pushing DIP switch S4
off (down) – see Configuration section for details.
CANdrive is supplied for use with 12V (7 to 16V) DC
operation. If 24V (19 to 30V) DC operation is required,
push DIP switch S5 to the off (down) position.
Connect a 1 Amp anti-surge fuse in the positive DC line
(pin 2).
Pins 1 and 3 are internally linked: pin 1 is typically used
as a power supply connection; pin 3 is typically used as
a common negative return for the gauge outputs.

Pins 4 and 6 give a variable current output for driving

switches S1, S2 and S3 – see Configuration section.

Operation and Maintenance
Operation
Maintenance and Warranty
Gauge driver outputs
The gauge outputs operate when CANdrive reads valid J1939
data for engine speed, oil pressure and coolant temperature.
If CANdrive stops receiving valid data, the gauge outputs
are maintained at the last known value for approximately
5 seconds, after which time the outputs turn off.
CANdrive has no user-serviceable parts. Maintenance is
therefore limited to the following preventative checks:
Indicating LEDs
All standard models have a green CAN LED. A flashing
CAN LED indicates that CANdrive is powered, but is not
receiving any J1939 data. A constantly lit CAN LED indicates
power on with good CANbus connection and J1939 activity.
(Note: J1939 activity can originate from ANY device on the
CANbus network, and may not necessarily be valid data from
the engine ECU.)
Model CDV300R has additional LEDs for indication of J1939transmitted engine faults. CANdrive responds to single
DM1 (active fault code) messages that contain SPN (Suspect
Parameter Number), FMI (Fault Mode Indicator) and
warning/stop lamp data. CANdrive also reads multi-packet
transport messages broadcast using the BAM protocol.
x Check that electrical connections are secure.
x Check that the CANdrive is securely mounted, and
kept free from ingress of water or build up of excessive
dust/dirt. The front label and casing may be wiped with
a clean, damp cloth. Do not use cleaning solvents.
CANdrive is supplied with a 2 year warranty on parts and
workmanship. In the event of a fault or technical query, please
contact your Murphy representative for technical support.
