ADCLOCK Jumper. __________________
The AD1200 series cards have an external clock input line
EXT CLOCK, that can be used to strobe A/D conversions when
the card is in mode 3. The EXT CLOCK line must be driven by
a high to low going edge. The ADMUX card’s relay made feed
back signal can be used to drive this input so allowing the A/D
converter to automatically start an A/D conversion as soon as the
relays have switched through the input signal. The ADMUX
card’s line is tristated and so several boards can all be jumpered
onto the AD1200 input, each board driving it as it is selected.
