ECUMASTER PMU
ECUMASTER PMU is an inteligent power management unit designed to replace the old, traditional
and often unreliable fuses and relays. PMU is not only an electronic switch, but a device that can
perform all kinds of advanced operations, validate logical conditions, manage abnormal situations,
as well as log its parameters for you to have an oversight. PMU allows you to power up external
devices such as fan, blinkers, wipers, oil pump etc. and create advanced strategies for those
devices using logic with failsafes, condition checking and many more functions. It can
communicate and work in tandem with other ECUMASTER CAN devices. It is equipped with over
and under current protection, surge protection, 3 gyroscope, accelerometer, LE Status lights,
Soft Start, Pulse Width Modulation with uty Cycle control and more.

CONNECTING PMU TO PC
CAN – USB in erface
To properly connect PMU to PC using USB 2.0 a special interface must be used. PMU Client
supports three interfaces:
•ECUMASTER USBtoCAN interface (can be bought directly from www.ecumaster.com)
•PEAK Systems PCAN-USB
•Kvaser USBcan
Each interface must have its drivers installed.
Interface must be bought separately.
ECUMASTER USB oCAN in erface
To use ECUMASTER USBtoCAN interface, user must be equipped in following items:
•USB A to USB B adapter to connect the interface to PC
•B-9 Cable to connect interface to PMU
•ECUMASTER USBtoCAN interface drivers, available at:
http://www.ecumaster.com/products/usb-to-can/
To install drivers run EUSBtoCAN_Driver_v1.0.exe and follow installation instructions.
Basic cable connection should look like this.
ECUMASTER USBtoCAN also has LE signaling ability:

Page 12

Connec ing USB in erface, wiring schema ics
To connect PMU to PC, CAN1 CANbus must be used. This is the CAN provided for us for PC
communication. To wire the USB - CAN interface, CAN1H and CAN1L pins (See PMU Pinout
section) must be used. Twisted pairing is also recommended. CANbus must also be terminated at
both ends of the bus. ECUMASTER USBtoCAN is equipped with one terminator that can be
switched on or off (See ECUMASTER USBtoCAN inter ace section).
If the Interface is connected, PMU must be supplied with power, both on the +12SW Pin (See PMU
Pinout section) and the M6 stud.
Here is a simple diagram of USB connection, please note that it assumes that the second
terminator is applied by the USBtoCAN interface:
PMU s a us
PMU device is fitted with LE that signals status of the PMU device.
Picture showing the LE location:
There are 6 possible states of PMU LE :

•Maximum unterminated cable length from device to CANbus is 30 cm
•Maximum bus length is 40m.
•Maximum of 30 nodes
•120 Ohm terminators must be applied at both ends of CAN bus.
•Twisted pairing is required.
For 500kbit/s connection (CAN 2) following rules must be abided:
•Maximum unterminated cable length from device to CANbus is 30 cm
•Maximum bus length is 100m.
•Maximum of 30 nodes
•120 Ohm terminators must be applied at both ends of CAN bus. PMU is equipped with
CAN2 terminator which can be turned on or off via PMU Client (Tree View → CAN Setup)
•Twisted pairing is required.

USING PMU SOFTWARE
Launching PMU sof ware
To run PMU software either doubleclick the icon on desktop, or use start menu to find it.
Using PMU sof ware
When PMU Client is launched for the first time, user will be asked to enter the name of his device.
All projects will then be saved to the directory corresponding to devices name.
After entering the Client, main window will appear:
Using the Client is pretty straightforward. The Project Tree window is the most significant one. You
can use it to set up analog inputs, configure power outputs, create functions etc.
To create elements, either use the toolbar with icons located on Project Tree window, use Alt + A
Keyboard shortcut or click Add button, then select the type of element you want to create.
Page 15

New device name

To upload current project to on-device flash memory, either use the Make Permanent button, or
use F2 keyboard button. The PMU status LE will flash with orange color (See PMU Status
section).
To save a copy of your current project on hard drive either use Ctrl+S keyboard shortcut, or use the
Clients toolbar.
Right on the main screen there are also windows with monitoring functionality. They are updated in
real time and show various parameters reported from particular pins as well as values of elements
created by user.

Monitoring Windows

On the left, there is a Tree View double clicking any item on it, will bring up it's window to current
desktop.
PMU Clien workflow
PMU Client workflow is really simple. You can monitor parameters of your channels, make
adjustments, follow the graph log to understand channels behavior, you can create elements, then
use those to control other elements or channels.
Elements and channels in this case can be anything, Power Output, Analog Input, Function, Switch
etc.
Let's take a look at two more in-depth use cases.
Page 17
Tree View

These are just two examples of how PMU Client can be used, but the possibilities are endless.
Page 18

ELEMENT TYPES
Analog Inpu
Analog inputs are input devices connected directly to the PMU.
Below is the list of analog inputs supported by PMU.
•Switch - Active High
•Switch - Active Low
•Rotary Switch
•Analog Sensor
Head to Wiring section to see wiring diagrams for each type of analog input.
Power Ou pu
Power Outputs are devices powered by PMU which are connected to particular output pins.
Power Output examples:
•Fuel Pump
•Fan
•Oil Pump
Every Power Output has over current, under current (both user configurable) and overheat
protection. They can be either turned on by default, controlled by function or triggered by another
element such as Analog Input
CANbus Message Objec (Mob)
CANbus Message Objects are interfaces needed for data gathering from CAN Stream. They read
a particular number of frames (user defined, up to 8) starting from particular I (also user defined)
from chosen CANbus. Maximum of 8 CANbus Message Objects can be created for each CANbus.
They also have special timeout flag which can be used to set up a different strategy if a connection
from another CAN device times out.
CANbus Inpu
CANbus Inputs use CANbus Message Objects to extract data from chosen frame. They are able to
read a user defined number of bits starting from user defined position, then apply offsets, division
or multiplication to the extracted data.
CANbus Keyboard
CANbus Keyboard is an element that provides communication with Keyboard. It is used to define
and handle Keyboard buttons, set their color, type etc.
Swi ch
You can use two types of switches:
•Latching Switch – switches between user defined number of states.
•Press Hold Switch – short press switches between high and low state, holding it triggers
third state.
Page 19

Number
Number is simply an integer. It can be either a typed in constant or value of chosen channel.
Number is mostly used for comparison or to control Duty Cycle in Pulse Width Modulation (See
PWM section).
Func ion
Function is one of the most important elements. It can be used to create a set of rules, conditions
to Power on an output device. Function always evaluates to either 0 or 1. If the function is used as
control channel for a Power Output, the Power Output will be turned on if function returns 1 and
turned off if function returns 0. Functions will be explained in depth later on in Functions section.
Wipers Module
Wipers module is a separate module to control the Wipers. It consists of two Power Outputs for
slow and fast wiper speed and an Analog Input for Park Switch. To use park functionality, Output
Pin O8 is provided to use for slow wiper speed. To see the wiring instructions, head to Wiring part
of the manual.
Blinkers Module
Blinkers module is a bit like Wipers Module, it is a separate element which controls the blinkers. It
consists of two Power Outputs for left and right blinkers and needs three inputs (ie. CANbus
Keyboard) to control the Left Blinker, Right Blinker and Hazard Lights.
CANbus Expor
CANbus Export allows you to broadcast (send) data to the CANbus, which then can be used by
other CAN device. For example, you can transmit the status of a Fan to other PMU or EMU Black
MANAGING ELEMENTS
Saving elemen s
Most elements can be saved to hard drive. To save your element, click icon on elements
toolbar and choose where you want to save it.
Loading saved elemen s
Elements that can be saved, can also be loaded. To load your element, click icon on elements
toolbar and choose file to load.
