Need Help Getting My FSBUS NG I/O Going Again..

Folks....I have some GOOD news and then BAD news....first the GOOD news...

I managed to get my FSKey Classic III up and running thanks to all your help...

Now the BAD news....I think I cooked the FSCOM III as I accidently hooked up 12V from PC to it instead of the 5V !! The two PIC's were hot and I can get nothing to work now !!!

Can I rescue the FSCOM Classic III ? If I replace the 2 PIC's and re-program would that do it or have I damaged other components on the FSCOM board ?

Any advice would be very appreciated ?

Thanks...JB

HI JB

Just for sure, the you mean the NE555 and the MAX232 ?

If yes you can replace them, no programming needed because they are ordinairy IC´s.

Hi Jan...

There are 2 PIC's on the FSCOM...one is the MAX232 but the other has the following written on top:

4312FFK
SN74HC04N

Do you think this 4312 will need special programming ?

Also, do you think I could have damaged any other parts on the FSCOM with the 12 V ?

Many thanks...JB

Then you have the FSCOM NG !!!
You must give me (us) the correct info if you want help, it's all in the manuals.
The 74HC04N is just an ordonairy IC, will cost you a few $ cents.
No programming needed.

And yes, there can be more damage, i.e. the transistor BC558, change that as well.

hi,
D1 if used will also have to be replaced.I dont use Fsbus now but did what you did.Fscom was fixable.Also be prepared to replace other chips on other boards if they were plugged in at the time.If i remember rightly
the 8535 suffered some damage on the Analogue inputs and had to replace it.
