General Information
Introduction
As part of the MurphyLink® family, the CANdrive™ offers a cost effective instrument solution
for modern electronic engines. CANdrive acts as an interface between ECU CANbus/J1939
transmitted data and standard electric indicating gages. CANdrive and electric gages are an
alternative solution to retrofitting of engine senders, magnetic pickups and associated wiring.
CANdrive has dedicated outputs for a tachometer, oil pressure, and coolant temperature
electric gages. Configurable switch settings allow for selectivity between 12 or 24 VDC
systems, and for all gage outputs to be selected for Murphy, VDO, or Datcon.
CANdrive is packaged in a compact, surface-mounted case with epoxy encapsulation for
maximum durability and environmental sealing. Electrical connection is through a 12-way
automotive-type connector.

Installation Instructions
Configuration
CANdrive modules are supplied with configuration switches located on the back side of the
unit. All switches are factory set to the ON (pushed up) position. Switches 1 to 5 allow
configuration of CANdrive operating options. Switch 6 is not used.
Configuration Table
Switch settings must be made according to the configuration table below.
WARNING: Adjustment of the switch positions must be made while
CANdrive is powered down.

Gage Compatibility Tables
Electrical Connection
CANdrive modules electrical connection is through a 12-way 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, model CDV300R).
CANdrive electrical connection is through a 12-way automotive type receptacle. A 30-inch
connector harness is included with each CANdrive model, and has each wire individually
labeled for ease of installation.

Function
Negative DC, power supply
Positive DC, power supply
Negative DC, gage common return
CANdrive modules are supplied for use with 12V (7 to 16V) DC operation. If 24V
(19 to 30V) DC operation is required, switch 5 must be pushed to the off (down)
position.
Connect a 1 Amp anti-surge fuse in the positive DC line (pin 2).
Oil pressure gage output
Coolant temperature gage output
Pins 4 and 6 give a variable current output for driving oil pressure and coolant
temperature electric gages. The outputs can operate with several different gauge
types, according to the settings of switches 1, 2, and 3 - see Configuration section
above.
Tachometer output
Pin 7 gives a square wave output (0V to battery positive DC), with a frequency that
is proportional to engine speed. At 1500 RPM engine speed, the output is
approximately 121 Hz, suitable for driving charge alternator based tachometers
such as the Murphy AT(H)A series. Pin 7 gives no output below 100 RPM engine
speed.
Connect each output to the appropriate gage/ tachometer signal input.
Gage/tachometer negative terminals should be common to battery negative, ideally
via dedicated wiring to terminal 3. (The use of dedicated return wiring to pin 3
rather than a ground return will minimize gage inaccuracies caused by ground
noise.)
CAN Hi
CAN Lo
Connect these terminals to the engine CANbus, taking care to observe the correct
polarity. The CANbus cable screen/shield is typically connected to ground at the
ECU end: refer to the engine manufacturer’s installation guidelines.
CANdrive modules are supplied with a 120 Ohm network terminating resistor fitted
in-circuit between CAN Hi and CAN Lo. If CANdrive module is not positioned at the
end of the CANbus network, remove the resistor by pushing switch 4 off (down).

NOTE: Connection Pins 9, 10, 11, and 12 are reserved for future use, or
are used in the factory setup of CANdrive modules. Do not connect wiring
or equipment to these terminals. Connection can result in permanent
damage to CANdrive modules.

Panel Mounting
WARNING: Do not install the CANdrive module near exhaust manifolds,
turbochargers or other engine locations that might exceed the
maximum allowable operating temperature of 185°F (85°C).
CANdrive modules are surface-mounted with four no. 4 screws, fixing center dimensions as
shown. Select screw length according to panel thickness, ensuring a maximum of 1/2 inch
(13mm) screw depth into the CANdrive module fixing holes.
Model CDV100F, with forward facing connector, is designed for surface-mounting inside an
enclosed panel.
Model CDV300F, with additional LEDs and rearward facing connector, is designed for front-ofpanel mounting: these modules require an additional 2.4” x 1.6” (60 x 40mm) cut-out for rear
access to connector and switches. The CDV300F includes a CDVG gasket (fitted into a well
behind the rim of the case) to provide front environmental sealing to IP65.
Before mounting, ensure that the final position allows access for:
•
Connection of the included wire harness.
•
Configuration of switches 1 - 5. Alternatively, set thee switches before mounting. See
Configuration section for full details.

Operation and Maintenance
Gage Driver Outputs
Gage outputs operate when CANdrive module reads valid J1939 data for engine speed, oil
pressure and coolant temperature. If CANdrive module stops receiving valid data, the gage
outputs are maintained at the last known value for approximately five seconds, after which time
the outputs are turned off.
Indicating LEDs
All standard models have a green CAN status LED. A flashing CAN status LED indicates that
CANdrive module is powered, but is not receiving any J1939 data. A constantly lit CAN status
LED indicates a good CANbus connection and J1939 activity. (Note: J1939 activity can
originate from ANY device on the CANbus network, and may not be valid data from the engine
ECU.)
Model CDV300R has additional LEDs for indication of engine faults, as transmitted from the
ECU. CANdrive modules respond to single DM1 (active fault code) messages that contain a
Suspect Parameter Number (SPN), Fault Mode Indicator (FMI) and warning/stop lamp data.
CANdrive modules also read multi-packet transport messages broadcast using the broadcast
address message (BAM) protocol.
LEDs typically light continuously to indicate a shutdown fault, and flash to indicate a (nonshutdown) warning fault.
CANdrive modules can handle up to 8 simultaneous faults at one time; additional fault
messages are not registered. When a fault becomes inactive and is no longer broadcast, the
appropriate LED goes out after approximately two seconds.

Maintenance
CANdrive modules have no user-serviceable parts. Maintenance is therefore limited to the
following preventative checks:
•
Check that electrical connections are secure.
•
Check that the CANdrive module is securely mounted and kept free from
exposure to 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.
