High Country Tek, Inc. (HCT) is North America’s foremost independent designer and producer of
modular, ruggedized digital and analog electronic controller products for the fluid power industry.
From our factory in California, we build, test and produce ‘specialty’ controllers for specific functions as
well as our ‘DVC family’ of fully adaptable user programmable units that can be integrated to enable large
area networked system solutions.
The modules are used in mobile, industrial and marine applications. They are also applied successfully in
other industry segments.
HCT’s every module is encapsulated in solid flame resistant material for maximum durability, electrical
integrity and complete environmental security. We deliberately select the highest quality components at
all times, ensuring 100% operating products.
HCT is a market leader in many application arenas, including hydraulic generator, e-Fan and hydraulic
fan system controls. These controllers realize significant fuel, emission and operational savings by

Welcome
Welcome to the High Country Tek Inc. (HCT) evc/epc user manual.
If you have any questions, requesting new features or finding errors, please contact us @ 530-265-3236
or e-mail at [e-mail], giving details of the issues and your contact information.
Introduction
This manual explains the installation and use of the evc/epc Digital Controllers. Users need to understand
the hazards in an electromechanical environment. Read this entire manual before installation. Pay particular
attention to caution and safety information.
Cautions
Changing setup values or operating modes while the machine is running may cause unintended machine
movement. It may lead to possible injury or death. Any moving parts should be disabled prior to
changing setup values or operating modes. In any case, exercise caution and work should be completed
only by qualified personnel.
Warranty Information
High Country Tek guarantees this product to be free of defects in materials and workmanship for one year
from the date shipped from the factory. Within this time frame, High Country Tek will provide evaluation of
warranted items free of charge. Warranty repair or replacement will be at the factory’s discretion.
Please have the units full Model / Part Number and Serial Number available when contacting the factory.
Do not return products to the factory without a RMA (Return Material Authorization) number.
Controller Updates
HCT continuously improves the controllers and makes additional information and/or features available.
Please check on-line at www.hctcontrols.com for the latest products, software update and information.

Product Application Guidelines
ALWAYS do the following
FULLY read this manual and accompanying data sheets BEFORE starting.
Isolate this unit from all other equipment BEFORE any form of welding.
Isolate the controller from ANY form of battery charging or battery boosting.
Be aware of the adjustments and reactions on the external equipment.
Operate the units within the temperature range.
Use the correct tools to do the job (i.e. P.C., software) etc.
Separate High Voltage AC cables from Low Voltage DC signal and supply cables.
Check that the units supply voltage is CORRECT, ‘ELECTRICALLY CLEAN’ and STABLE.
Make sure the controller output voltage & current is compatible with the equipment!
All unused wires / terminals should be terminated safely.
Ensure ALL connectors have no unintended SHORT or OPEN circuits.
Ensure ALL connectors are wired correctly, secure, locked in place and fully connected.
Observe all the set-up procedures in this manual.
Follow and abide by local and country health & safety standards!
NEVER do the following
Arc Weld or Charge Batteries with this module connected as damage can/will occur.
Attempt to use this unit if you are unsure of electrical OR mechanical connections or expected operation.
Use a power supply that is not rated for the output current under full load.
Allow wires to or from the unit to short circuit (to each other or chassis/cabinet etc.).
Use this controller in areas of intense Radio Frequency fields without adequate screening.
Disconnect or connect wires to or from this unit unless it isolated from the power supply.
Use this unit in temperatures that exceed the limits.
Start or operate this controller without ensuring ALL work areas are clear of personnel!
Software Safety
The GUI and controller software give the user flexibility and ease of use, even for novice users.
The GUI is not intended to be connected to a non-evc/epc unit. Care must be taken to use the correct GUI
and hardware combination. After program entries, cycle the power to ensure changes are accepted by the
unit.
When the GUI is first connected to a powered controller, a ‘Handshake’ takes place that confirms the
internal software (BIOS) is compatible with the GUI software. Only then the PC and the module are allowed
to communicate and exchange data.
If an error or miss-match is detected, or loss of communication, the GUI software will indicate “OFF LINE”
and NOT allow communications until the problem is corrected.

Using the evc/epc with your PC
Install the Graphical User Interface (GUI) in a host PC. Use the default file locations for easy future
update. The user has the option to choose where the program should be located.
Don’t run the GUI from a network as it needs access to certain files only in the Windows directories.
System Requirements
Windows XP, Vista or Windows7, 100MB or greater free disk space.
Insert the CD into the PC drive and follow the on-screen instructions. This will install the evc/epc GUI,
manual and help files.
Install the Com Port drivers for the evc/epc.
Start HCT Products Digital Controllers evc/epc USB Serial Drivers, CDMxxxxx_setup.exe
To insure a complete install, run the CDMxxxxx twice.
The evc/epc can be powered by +5V USB to allow configuration without connecting to a 12/24Vdc system.
A message “Supply Voltage is Low” appears on the screen. You may fully communicate, change, and
save settings to the unit. You can not drive the coil(s).

evc/epcController
WithSAEJ1939Interface
At start up the GUI searches the PC com ports for the evc/epc controller.
The default MAC ID is 1. If the evc/epc has been programmed with a different Mac ID, you can search
for the controller by “Find Module” or enter the Mac ID. The “Find Module” will restart the operation when
the unit responds with its information and Mac ID.
The MAC ID determines the module’s Command and Status PGN addresses on the SAE J1939 bus. The
user may command many evc/epc modules on a single J1939 bus. Please see SAE J1939 section.

evc/epc GUI
File

All changes made through the GUI are temporary until saved permanently.
Permanently save settings to unit: Save the settings from the RAM (temporary) memory to the unit’s
EEPROM (permanent memory).
Permanently save settings to unit & file (.dat): Permanently save the settings to the unit’s EEPROM
and to a data file that may be loaded later.
Settings will be lost if not permanently saved before power cycle.
Reset the unit with a power cycle, you must remove both the USB cable and DC power from the
unit.
Restore unit to last permanent settings saved: Reload RAM with settings stored in the EEPROM. This
will undo all changes made since the last Permanent Save.
Restore unit settings from data file (.dat): Load the data file from the PC to the evc/epc for different
modes of operation.
Restore unit from v1.03 data file: Load the previous version data file from the PC to the evc/epc for
different modes of operation.
