Hi,
good day~

i having IFC Mainbrain card, Dual brush motor card, Control Panel card, Power card.
i use 12V power supply to supply to the board and connect ext out 12V to ext in 12V of Dual brush motor card.
12V DC motor is connected to the card.
RS232 port of the IFC card is connected to a RS232-to-USB convertor and connected to my PC thru USB port.
UIC00B programmer is connected to my PC thru another USB port.

1)
each time while i programming my IFC using UIC00B, my DC motor will be like triggered /shake a bit with "tek tek tek" sound (but not turning la, just shake a bit), is that normal? that's due to the current surge due to the programming? and cause current disturbance at the motor?

2)
with the RS232 and programmer connected to my PC (with DC motor connect to the IFC card),
even though i didnt send any command to the IFC regarding the DC motor,
i just get the IFC to send RS232 data to the PC,
very often my PC will become blue screen in the middle of the program,
the timing of the blue screen occurance is not consistence and random.
After it turn blue screen i need to restart my PC again.
Any idea?


Pls advise and thanks

Bluescreen normally is cause by driver problem.

You might need to check the driver of USB to Serial
