General Information Introduction As part of the MurphyLink ® family, the Murphy 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 tempera

Installation Instructions Configuration CANdrive modules are supplied with 5 circuit board links soldered in place. These wire links, labeled L1 through L5, are located on the back side of the unit. The links allow configuration of operating options by snipping the appropriate wire according to the following configuration table. WARNING: The configuration links are one-time breakable and are not replaceable. Care must therefore be taken to select the correc

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, an

Terminal Functions PIN Function 1 Negative DC, power supply 2 Positive DC, power supply 3 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, remove (cut) rear link L2. Connect a 1 Amp anti-surge fuse in the positive DC line (pin 2). 4 Oil pressure gage output 6 Coolant temperature gage output Pins 4 and 6 give a variable current output for driving oil pressure and coolant temperature

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 de

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 no

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. Section 78 00-02-0618 04-10-07 - 7 -
