Analog output terminals (D/A OUT 0 and D/A OUT 1)
You can connect up to two analog output connections to the screw terminal pins 13 and 14 (D/A OUT 0 and D/A OUT 1). Refer to the pinout diagrams on page 13 for the location of these pins.
Each channel can be paced individually at rates up to 10,000 updates per second. Both channels can be paced simultaneously using the same time base at 5000 updates per channel. The
Digital I/O terminals (Port A0 to A7, and Port B0 to B7)
You can connect up to 16 digital I/O lines to the screw terminal containing pins 21 to 40 (Port A0 to Port A7, and Port B0 to Port B7.) Refer to the pinout diagrams on page 13 for the location of these pins. You can configure each digital port for either input or output.
When you configure the digital bits for input, you can use the digital I/O terminals to detect the state of any TTL level input. Refer to the schematic shown in Figure 8. If the switch is set to the +5 V input, Port A0 reads TRUE (1). If you move the switch to GND, Port A0 reads FALSE.
