Appendix A:
Using the Ignition System
Manager (ISM)
The Ignition System Manager (ISM) is a software that
can monitor the system’s voltage level and configure the
features that the Power Ignition Module provides.
For sample ISM code, see
ISM
folder under LVC-5550S
Utility on the
Driver and Manual CD.
Running the Program
Just double click the ISM.exe to launch the ISM.
The program can configure the following values:
Voltage
: It shows the current power system.
Power Input System
: Select either 12V or 24V for vehicular
power input.
Startup Voltage (V):
If the DC-in voltage is not higher
than this value, the system will not be able to start up.
Shutdown Voltage (V)
: If the DC-in voltage is lower than
the shutdown voltage, the system will start shutdown
process automatically. (Refer to selector 2 of SW1 dip
switch on the board)
Power-on Delay (min/sec):
Select power-on delay value
to indicate the time to delay powering on the system.
(Refer to the power-on flow chart in Chapter 4)
Power-off Delay (hr/min/sec)
: Select power-off delay
value to indicate the time to delay powering off the system
(Refer to the power-off flow chart in Chapter 4)
Serial Port:
Select the serial communication port.
After you have made changes, click
Apply
to apply the
changes to the Ignition controller or
Cancel
to cancel the
changes.
Click
Cancel
to exit the ISM program.
Note:
You will have to enable (the default is enabled)
1.
the
selector 2 (Low Voltage Detection) of SW1 dip
switch
on the LVB-5550 to enable automatic
shutdown function. (Refer to
Select MCU Detect
Function for power ignition behavior (SW1)
in
Chapter 3 Block Diagram
).
Refer to the
2.
flow chart
in Chapter 4 for more
information about how the system behave
according to these parameter set here.
