If you open up the back panel of the unit where your mot boards and cpu are there is a panel with test points. You can test all the dc voltages there including the 5 and 12 volts ones for the cpu.

1. Palm down the GSM and open the safety cover to check input voltage +12VDC (at KDC2 3PL pins 2 to 3) and output voltage +5VDC (at KDC2 2PL pin 4 to 3) at the DC/DC converter. The DC/DC converter is located inside the control panel assembly ("Nose c

Resistor Help Needed

Three LEDs, 3.5volts @.02amps each is 10.5volts. You said you calculated out an 82 ohm resistor so 82 ohms * .02amps is 1.64volts, I guess your going to use a 12volt supply. P=I*E =.02amps * 1.64volts =.033watts so a .25watt resistor will be fine

Hello all, Recently, we had a bad problem of block protection. You know, our programmer can't protect the 29F002 flash ROM, and our motherboard doesn't have 12 volts output for BIOS. So, from the preceding phenomena, it seems impossible to get a prot

Kel- My first impulse is to tell you to go ahead and try it your way. We all need to learn from our mistakes to find the right way. What you are proposing is called a "smoke" test. As long as you can keep the smoke inside the device, in your case th
