HFX Product Family
12.0 FUNCTIONALITY AND BASIC OPERATION
12.1

Reset Procedure

A different service tool is required for the reset
procedure. Run the HFX Service Tool installation
file setup.exe in the Service Tool folder of the HFX
Support Package. Follow the installation prompts to
install the service tool.
When launching the HFX Service Tool you may be
prompted for a password. The latest passwords
can be found in the file `Password.txt', located in
the Service Tool folder of the HFX support package.
You have the option to select `Save password and
S/N', which stores the password for the next time
the software is used. Note: The current read only
password is: "YZJI-K2LH-0KCX-CYRC"
At initial startup, the controller enters the bootloader.
A bootloader is simply a small program that loads
the rest of the firmware when the controller is
initially powered up. This firmware resides in the
flash memory and provides the necessary memory
mapping and instructions for the controller, allowing
the application program to be processed. The
bootstrap mechanism provides the means to enter
the bootloader. The IEC bootstrap mechanism is as
follows:
1. Check for PWM1&2 ≥ 11.0 V
2. Delay 3 seconds
3. If either the HFX service tool or IEC is connected,
abort and don't load IEC app from flash
4. Otherwise, load and run the IEC app in flash like
normal.
This provides a mechanism to remove a frozen
application.
1. Load a new application, or
2. Reset origin will clear entire application memory.
Boot Process
PWM 1&2 ≥ 11 VDC
IEC or HFX service tool is detected within delay period
Abort and don't load IEC app from ash
No
Continue Booting &
Load IEC from ash

Sleep Mode (Time Delay Operation)

Sleep Mode provides a mechanism to have a
controlled shutdown of the vehicle control system.
This is a benefit because the unit can be put
into an idle state where less current is required
thus extending battery life. It is also useful with
applications where, prior to shut down, the
controller needs to return key functional outputs
to a predefined or home position.
Operating Enter Sleep
Mode bit State
Sleep True
Awaken False
The controller will enter sleep by setting
the "enterSleep" bit to TRUE anytime that
the "sleepAllowed" status bit is TRUE
({Sleep is high} or {IGN is low or not connected}).
The controller will awaken from sleep if
{Sleep is low or not connected} and {IGN is high}
Sleep current 2.4 mA, @ 10 V, 1.9 mA @ 15 V,
1.6 mA@ 20 V, 1.2 mA @ 25 V

Task Configuration

The maximum number of tasks is 5. The controller
supports the following tasks:
Cyclic: Task processed in a predefined time.
•
Freewheeling: Task processed as soon as the
•
program is started. When complete, it will
automatically restart in a continuous loop.
Note: There are no external events available to trigger
task execution.
Sleep Allowed State
True (Sleep Pin> approximately 6.6 V or
Ignition Pin < approximately 6.6 V)
False (Sleep Pin< approximately 6.6 V and
Ignition Pin > approximately 6.6 V)
