IRQ routing and opto IRQs
6000 Series user’s manual
Optically isolated inputs
The PC Microcontroller provides two remote, isolated inputs. The first
input OPTO A+, OPTO COM on the AUX I/O connector, resets the CPU
when a voltage input between 4.0V to 6.0 VDC is applied. The second
input, OPTO B+, OPTO COM on the AUX I/O connector, activates an
IRQ9.
Pin 2 of P1 on the breakout board is the opto-isolated return pin com-
mon to both optically isolated A and B inputs. Octagon recommends
that these input sources have a common ground point established that
is tied to pin 2 on P1. See the following figure for recommended timing
usage.
The optical isolators provide 300 VDC of isolation between the optically
isolated inputs and the card.
