Digital I/O Functionality 4 This chapter describes the primary functions of the digital inputs and outputs on the NI CVS-1450 device. This chapter also includes guidelines for connecting the digital I/O and for setting up a typical CVS-1450 device. Overview The digital I/O functions are accessible through 2 TTL inputs, 10 TTL outputs, 13 isolated inputs, and 4 isolated outputs. You can use input signals as triggers, product selection ports, or to read quadrature encoders.
Chapter 4 Digital I/O Functionality TTL Inputs and Outputs TTL is a fast-switching, 5 V, digital, signaling standard commonly used for applications that require high precision, such as camera triggering. TTL inputs and outputs do not require a separate power supply. Caution Do not connect voltage or current sources to TTL outputs. Doing so could damage the CVS-1450 device. Table 4-1 summarizes the TTL inputs and outputs available on the CVS-1450 device. Table 4-1.
Chapter 4 Digital I/O Functionality Table 4-2 summarizes the isolated inputs and outputs available on the CVS-1450 device. Table 4-2.
Chapter 4 Digital I/O Functionality For more information about creating a timed pulse output, refer to the Timed Pulse Output section. TTL Input 0, TTL Input 1, TRIG 0, and ISO Input 8 can alternatively function as general purpose inputs. ISO input 5 can alternatively function as a latch input for the product selection port.
Chapter 4 Digital I/O Functionality wait for the next trigger. In either case, the pulse output generation stops and resets if the pulse mode parameter is set to Stop. Figure 4-1 shows an output pulse when a trigger is selected. Trigger Input Output Pulse Figure 4-1. Output Pulse When Trigger Is Selected Pulse Modes Each pulse generator has a Start and a Stop mode. Configure the pulse generator when in Stop mode and then set it to Start mode.
Chapter 4 Digital I/O Functionality Figure 4-2 shows the output of a pulse generator configured to look for a rising edge trigger and output a high pulse with a microsecond width and delay. Delay Width Trigger Pulse Figure 4-2. High Pulse with Rising Edge Trigger Figure 4-3 shows how to create a high and low pulse train with a microsecond delay and width. High Pulse Train Delay Width Delay Width Low Pulse Train Software Start Figure 4-3.

Trigger Low Pulse Delay Width Phase A Phase B Figure 4-4. Rising Edge Trigger, Low Pulse with a Quadrature Encoder Delay Product Selection Port The product selection port consists of a group of five isolated digital inputs that the software running on the CVS-1450 device reads simultaneously.
Chapter 4 Digital I/O Functionality Table 4-3 lists the product selection ports. Table 4-3. Product Selection Port Function External Connection Data(5), rising edge latch ISO Input 5 Data(4) ISO Input 4 Data(3) ISO Input 3 Data(2) ISO Input 2 Data(1) ISO Input 1 Data(0) ISO Input 0 General-Purpose I/O General-purpose inputs and outputs are available as both TTL and isolated connections.
Chapter 4 Digital I/O Functionality An example of using general-purpose outputs is driving a relay that turns on an Inspection in Progress light for an operator to see while the inspection sequence is running.
Chapter 4 Digital I/O Functionality Shutdown Shutdown mode is a software-enabled feature, that when activated, allows an external device to halt the CVS-1450 device processing operations. Additionally, Shutdown mode allows you to specify user-defined shutdown states for all fault conditions. When Shutdown mode is enabled and the shutdown input signal, ISO Input 11, turns off, the CVS-1450 device registers an external shutdown condition.
Chapter 4 Digital I/O Functionality Configure the watchdog timer to take one of the following actions when it expires: Caution Use the Indicator Only option only to test the watchdog timer. If software becomes unresponsive, it cannot be relied upon to send notification to the host. • Indicator Only—This option sends the expiration signal back to the development machine through software. True indicates an expired watchdog timer. False indicates an unexpired watchdog timer.
Chapter 4 Digital I/O Functionality Considerations When Connecting the Digital I/O The isolated trigger inputs on the CVS-1450 device are current sinking and optically isolated. Figure 4-6 shows the trigger input interface circuit. Wiring an Isolated Input to a Sourcing Output Device You can wire an isolated input to a sourcing output device, as shown in the example in Figure 4-5. Refer to Appendix B, Specifications, for switching thresholds and current requirements.
Chapter 4 Digital I/O Functionality Viso Vcc Digital Output Load Ciso CVS-1450 device Figure 4-6. Example of Connecting an Isolated Output to an External Load Protecting Inductive Loads When an inductive load, such as a relay or solenoid, is connected to an output, a large counter-electromotive force may occur at switching time due to energy stored in the inductive load. This flyback voltage can damage the outputs and the power supply.
Chapter 4 Digital I/O Functionality Viso Vcc Digital Output Load Ciso External Flyback Diode for Inductive Loads CVS-1450 device Figure 4-7. Example of Using an External Flyback Diode for Inductive Loads Transmission Line Effects Transmission line effects can degrade the signals on the I/O cables and cause instability. To minimize transmission line effects, use twisted-pair wires with a characteristic impedance of 118 Ω to connect external signals to the 44-pin I/O DSUB connector.

5 Deployment This chapter provides guidelines for connecting the NI CVS-1450 device to a network. Connecting Multiple CVS-1450 Devices An Ethernet connection between the development computer and the CVS-1450 device allows you to assign an IP address, configure the CVS-1450 device, download inspection tasks, and remotely monitor an ongoing inspection. As with all Ethernet devices, you can connect multiple CVS-1450 devices to the same network, as shown in Figure 5-1. Figure 5-1.
Chapter 5 Deployment To connect multiple CVS-1450 devices to the same network, each CVS-1450 device must have a unique IP address. By default, the configuration utility running on the development computer displays each CVS-1450 device that exists on the subnet. To add entries for CVS-1450 devices that exist on other subnets, you must know the IP address assigned to each CVS-1450 device.
Chapter 5 Deployment Figure 5-3. CVS-1450 Device Connected to a Monitor At any time, you can reconnect the host machine to the CVS-1450 device and remotely monitor progress.
A Troubleshooting This appendix provides instructions for troubleshooting the NI CVS-1450 device. Software Configuration Problems CVS-1450 Device Does Not Appear in MAX or in Vision Builder AI Possible causes and solutions: • Verify that there is power to the CVS-1450 device and that both the CVS-1450 device and the development computer are properly connected to the network. The POWER OK LED should be lit.
Appendix A Troubleshooting • Another device on the network is using the IP address assigned to the CVS-1450 device. Either remove or reconfigure the other device, or reconfigure the CVS-1450 device IP address. • The DIP switch settings on the CVS-1450 device may be invalid, such as all switches set to the ON position. Change the DIP switch settings and reset the CVS-1450 device by pressing the RESET button on the CVS-1450 device for at least two seconds.
Appendix A 4. Troubleshooting Right-click the name of the device you want to reformat and select Format Disk. The video output connected to the CVS-1450 device displays the status of the format. 5.

Refer to the NI 1450 Series Compact Vision System Quick Start Guide, or Chapter 2, Setup and Configuration, of this manual for information about configuring the CVS-1450 device for your application.
Appendix A Troubleshooting Cannot Drive Isolated Outputs Verify that you have power connected to Viso and Ciso inputs on the CVS-1450 device power connector and that the contact at the screw terminals is solid. Because these outputs are electrically isolated from the CVS-1450 device main supply, they require power in addition to the CVS-1450 device main supply.
