Chapter 2 LEDs, DIP Switches, and Connectors

TRIG 0

Note Additional isolated inputs are available on the 44-pin DSUB connector.
Caution
These isolated inputs are compatible with 5 V logic if the external circuit meets
the voltage and current requirements listed in the Specifications section of Getting Started
with the NI CVS-1450 Series Compact Vision System.

TRIG 1 and TRIG 2

Note Additional TTL outputs are available on the 44-pin DSUB connector.
Caution Do not connect voltage or current sources to TTL outputs. Doing so could
damage the NI CVS-1450 device.

General-Purpose Digital I/O

Note Isolated inputs are compatible with 5 V logic if the external circuit meets the voltage
and current requirements listed in the Specifications section of Getting Started with the
NI CVS-1450 Series Compact Vision System.
NI CVS-1450 Series User Manual
The TRIG 0 isolated input on the NI CVS-1450 device provides connection
to external devices, such as proximity sensors and start/stop buttons. For
easy connection to the TRIG 0 input, use the National Instruments SMB
111 coaxial cable (part number 763422-01).
You can use the two TTL outputs available on the SMB connectors for
triggering cameras and external interfaces, such as lighting control units.
For easy connection to the TTL outputs, use the National Instruments
SMB 111 coaxial cable (part number 763422-01).
The 44-pin DSUB connector, shown in Figure 2-8, provides access to the
general-purpose digital inputs and outputs. The general-purpose digital
I/O available on this connector includes 2 TTL inputs, 8 TTL outputs,
12 isolated inputs, and 4 isolated outputs. For easy connection to the digital
I/O connector, use the NI Vision I/O Terminal Block and Prototyping
Accessory (part number 779166-01).
For detailed information about digital I/O functionality and recommended
use cases, refer to Chapter 3, Digital I/O Functionality.
