Using the Ignition System Manager (ISM)

Embedded and Industrial Computing

Appendix A

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.
