Is the blink rate adjustable? If not, it is normal for different systems to have different blink rates? Thanks.
Yes, but only in hardware. There is a 555 timer on the mainboard (position B3) that generates the flash timing. Change the resistor values to adjust frequency and duty cycle. Read the NE555 datasheet (at www.alldatasheet.com) for further details.
