I have just made the DIO board for FSBus and I have started populating it.I have a couple of questions on the components:What are the values of R4 to R11What is the value of R12What are the values of R21 to R28What are the values of C8 to C15Why does Q1 (16mhz crystal) have 3 pads/holes.ThanksDavid

Just another one on the Com NG board:What is the Australian equivelent of the ZF 3.9 diode - D2What is the Australian equiv. of D1 1,5KE6V8AWhat is the Australian equiv. of F1 HSN75 2,7A fuseDavid

FSIO NG:What are the values of R4 to R11---1 kohm (see page 24/30 in docs)What is the value of R12--- 22 ohm (see schema on page 5/30)What are the values of R21 to R28--- 180 ohm )see page 26/30)What are the values of C8 to C15---- 220 nanofarad(see page 24/30)Why does Q1 (16mhz crystal) have 3 pads/holes.--- I asked that once at an experienced electrotechniciam, He said you could also use a resonator (not sure wheter I remembered the name exactly). They have 3 pins, middle is ground. So if you use the crystal, just leave out the middle hole.FSCOM NGI do not know. I would think that these names are all international. You would only need the Zener diode ZF3,9, the other 2 are optional. Just take care for a good protected power supplyregardsNorberthttp://home.wanadoo.nl/norbert.bosch/

Thanks as always Norbert.
