3.3 Bi-directional digital I/Os
The ADQ-250 series provides one bi-directional 8 bit wide digital I/O port (DIO_7..0). If the
digital port is configured as input the pins can be monitored on bit-change and can generate
an interrupt event.
The port can be attached by the HDMI connector ST9 at the front panel. A suitable terminal
block is available as an option (see chapter 4.2.4 on page 32).
Note
: After power-up all ports are configured as input.
3.3.1 Wiring
When wiring digital I/Os take care that the TTL level is met (see specifications on page 27)
and that a reference to PC ground (GND_PC at ST9) must be established. The max. output
current is I
O
= 24 mA.
