NI CVS-1450 Series Overview

This chapter provides an overview of the features and components of the National Instruments CVS-1450 Series compact vision system.

About the NI CVS-1450 Series

NI CVS-1450 Series devices are easy-to-use, distributed, real-time imaging systems that acquire, process, and display images from IEEE 1394 cameras conforming to the IIDC 1394-based Digital Camera Specification, Version 1.30. The CVS-1450 Series also provides multiple digital input/output (I/O) options for communicating with external devices to configure and start an inspection and to indicate results.

An Ethernet connection between the CVS-1450 device and a development computer allows you to display measurement results and status information and to configure the CVS-1450 device settings. When configured, the CVS-1450 device can run applications without a connection to the development computer.

Each CVS-1450 device ships with documentation and the NI-IMAQ for IEEE 1394 Cameras driver software, which is licensed for one development system and one deployment system.

Hardware Overview

The CVS-1450 device front panel consists of a VGA connector, an RS-232 serial port, a 10/100 Ethernet connector, and three IEEE 1394a ports.

The CVS-1450 device also includes LEDs for communicating system status, DIP switches that specify startup options, TTL inputs and outputs for triggering, and isolated inputs and outputs for connecting to external devices, such as PLCs, sensors, LED indicators, and start/stop buttons. The isolated inputs and outputs on the CVS-1450 device provide an easy means for preventing ground loops that could degrade signal integrity.

Caution The isolation on the CVS-1450 device is not safety isolation.

Available Camera Bandwidth

The IEEE 1394 bus provides a fixed amount of bandwidth that is shared among the three IEEE 1394a ports on the CVS-1450 device. These ports provide direct connection for up to three DCAM-compliant IEEE 1394 cameras, depending on the amount of bandwidth each camera requires. Higher frame rates and larger image sizes require a higher data transfer rate and use more bandwidth.

Table 1-1 shows the maximum number of cameras the CVS-1450 device supports for three common video formats. Use this table as a guide when determining the combination of cameras to use in your application.

Note Bandwidth calculations described in Table 1-1 do not include software decoding of

YUV images to RGB. This conversion time is dependent on processor speed.

By triggering your cameras at a frame rate slower than those rates listed in Table 1-1, you can operate more cameras simultaneously. If the camera combination exceeds the amount of available bandwidth, the software returns an Insufficient Resources error.

Chapter 1 NI CVS-1450 Series Overview

Software Overview

Programming the CVS-1450 device requires NI-IMAQ for IEEE 1394

Cameras 1.5 (or later) driver software to control the hardware and one of

the following application software packages to process images.

• NI Vision Builder for Automated Inspection (AI) 2.0 or later—Allows you to configure solutions to common inspection tasks

• LabVIEW Real-Time Module 7.0 or later with the Vision Development Module 7.0 or later—Provides customizable control over acquisition hardware and algorithms

The following sections provide an overview of the driver software and the application software. For detailed information about individual software packages, refer to the documentation specific to the package.

NI-IMAQ for IEEE 1394 Cameras Driver Software

The NI-IMAQ for IEEE 1394 Cameras driver software ships with the CVS-1450 device. NI-IMAQ for IEEE 1394 Cameras is the interface path between the application software and the CVS-1450 device.

NI-IMAQ for IEEE 1394 Cameras includes an extensive library of VIs you can call from LabVIEW. These VIs include routines for video configuration, continuous and single-shot image acquisition, trigger control, and register-level camera configuration.

The NI-IMAQ for IEEE 1394 Cameras driver software performs all functions necessary for acquiring and saving images but does not perform image analysis. For image analysis functionality, refer to the National

Instruments Application Software section.

NI-IMAQ for IEEE 1394 Cameras features both high-level and low-level functions. A function that acquires images in multi-buffer, single-shot, or continuous mode is an example of a high-level function. A function that requires advanced understanding of the CVS-1450 device and image acquisition, such as configuring an image sequence, is an example of a low-level function.

The NI-IMAQ for IEEE 1394 Cameras software handles many of the complex issues between the CVS-1450 device and the camera, such as IEEE 1394 bus communication and camera control.

NI CVS-1450 Series User Manual 1-4 ni.com

National Instruments Application Software

This section describes National Instruments application software packages you can use to analyze and process the images you acquire with the CVS-1450 device.

Vision Builder for Automated Inspection

NI Vision Builder for Automated Inspection (AI) is configurable machine vision software that you can use to prototype, benchmark, and deploy machine vision applications.

Refer to Appendix A, Troubleshooting, for information about troubleshooting LEDs.

STATUS

POWER OK

Chapter 3 LEDs, DIP Switches, and Connectors

POWER OK LED

Under normal operating conditions, the POWER OK LED remains green while the CVS-1450 device is powered on. A green POWER OK LED indicates that CVS-1450 device main power is receiving power and that the CVS-1450 device is not in a fault state. A red POWER OK LED indicates that the CVS-1450 device has shut down because of a fault state. A fault state occurs when the user shutdown input is asserted, the processor overheats, or the watchdog timer expires.

Note The POWER OK LED does not indicate the status of the isolated power, Viso.

STATUS LED

The orange STATUS LED remains off under normal operating conditions and flashes a specific number of times to indicate error conditions or certain DIP switch settings. The STATUS LED remains lit if the CVS-1450 device detects an internal error.

Refer to the Hardware Errors section of Appendix A, Troubleshooting, for information about LED error indications.

ACT/LINK LED

100 Mbps LED

The orange ACT/LINK LED blinks when the CVS-1450 device receives data from or transmits data to the network through the Ethernet connection. Unrelated network activity causes this LED to blink occasionally even when the CVS-1450 device is inactive.

Figure 3-2 shows the location of the ACT/LINK LED on the CVS-1450 device.

The green 100 Mbps LED is lit when the network provides 100 Mbps support and the CVS-1450 device is communicating at 100 Mbps. If the 100 Mbps LED is not lit, the CVS-1450 device is not operating at 100 Mbps.

IP RESET Switch

NO APP Switch

Chapter 3 LEDs, DIP Switches, and Connectors

To clear the CVS-1450 device IP settings, move the IP RESET switch to the ON position and reset the CVS-1450 device. Use IP RESET to reset the TCP/IP settings when moving the system from one subnet to another or when the current TCP/IP settings are invalid.

Resetting the CVS-1450 device with the IP RESET switch in the ON position resets the IP address to 0.0.0.0. You can then set up a new network configuration for the CVS-1450 device from a development machine on the same subnet, or you can use an Ethernet crossover cable to connect the CVS-1450 device directly to the development computer.

To prevent the CVS-1450 device from automatically running VIs at startup, move the NO APP switch to the ON position and reset the CVS-1450 device. If the CVS-1450 device becomes inaccessible because of a startup program, enable the NO APP switch and reset the CVS-1450 device.

Enable this switch to prevent the CVS-1450 device default startup program or Vision Builder AI from running at startup.

USER 1 Switch (LabVIEW Real-Time Module Users)

The USER 1 switch is user-configurable and has no default functionality. You can use the RT Read Switch VI to read the USER 1 switch state and perform a custom action based on the current switch state position.

Digital I/O Functionality

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. Uses for output signals include controlling camera reset and exposure, controlling strobe lighting, outputting inspection results, or communicating with PLCs. You can also define the functions of digital input and output signals.

For information about how to use the LabVIEW Real-Time Module to implement specific digital I/O functions, refer to the application software documentation and examples in the following locations:

TTL and Isolated Inputs and Outputs

This section describes the TTL and Isolated I/O functions available on the CVS-1450 device.

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.

Isolated Inputs and Outputs

The isolated inputs and outputs on the CVS-1450 device have a separate ground reference from the main CVS-1450 device supply, providing an easy means to prevent ground loops that can introduce noise into a system. You can apply signals up to 30 V to the isolated inputs. The voltage swing of the isolated outputs is determined by the Viso you supply on the connector.

Trigger Inputs

Trigger inputs are available from both TTL inputs and isolated inputs. You can use these trigger inputs to synchronize the CVS-1450 device with an external event, such as the assertion of a signal generated by a proximity sensor or a PLC to indicate that an inspection item is passing in front of the camera. The CVS-1450 device uses this input to initiate a timed pulse that can be used for camera control, lighting control, encoder pulse counting, and result output timing.

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.

Timed Pulse Output

The CVS-1450 device is capable of timed pulse output on six different digital outputs, which provides precise control over time-critical signals, such as camera exposure. This section describes the various uses for the timed pulse output and the parameters you can set to control these outputs.

Uses for timed pulse output include controlling camera reset and exposure, controlling strobe lighting, operating plungers on an assembly line, and communicating with PLCs. You can configure the start of the pulse output generation to occur from software or from a rising or falling edge of a trigger input.

In addition to controlling the timing of pulse output, you can also configure the polarity of the output signal, resulting in a high-true or low-true signal. Based on the polarity setting, the output signal asserts after the appropriate delay time and de-asserts after the configured pulse width. You can set the delay time in microseconds or in quadrature encoder counts from the start signal—either a hardware trigger or a software command. Width is always configured in microseconds.

Initiating a Timed Pulse

Each timed pulse generator has a trigger input that specifies whether to wait on a particular trigger input to generate the pulse or to immediately generate the pulse when software sets the pulse mode to Start.

When the pulse generator is configured for a particular trigger input, after generating a pulse, it waits for another trigger before generating another pulse. When the pulse generator is configured to immediately generate the pulse on a software start, after generating a pulse, it immediately generates another pulse.

If the trigger input is set to Immediate, the pulse generation occurs as soon as the pulse mode is set to Start. If the trigger input is set to one of the hardware trigger inputs, the timed pulse output waits for an assertion edge on the appropriate trigger input. The assertion edge is configurable based on the trigger polarity parameter. It then generates one pulse and rearms to

NI CVS-1450 Series User Manual 4-4 ni.com

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.

Pulse Delay

Pulse delay is the amount of time between a trigger and the first (assertion) edge of an output pulse. The pulse delay is configurable in units of microseconds or quadrature encoder counts. If configured for microseconds, available values are between 10 µs and 4,294,967,295 µs, which is 4,294 seconds, or approximately 71 minutes. If the delay is configured for quadrature encoder counts, the range of choices is 0 counts to 4,294,967,295 counts.

Pulse Width

Pulse width is the amount of time between the first (assertion) edge of a pulse and the second (deassertion) edge. Pulse width is configurable only in microseconds from 10 µs to 4,294,967,295 µs.

Trigger Polarity

Each pulse generator can be individually configured for rising or falling edge triggering. Even if multiple pulse generators are using the same trigger, each can have different polarities.

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.

Quadrature Encoder

The quadrature encoder uses ISO Input 6 for its Phase A input and ISO Input 7 for its Phase B input. Encoder speed is limited by the speed of the isolated inputs. Each isolated input can change at a maximum rate of 100 kHz, making the maximum encoder rate 400,000 counts/s.

The quadrature encoder can also be used as a timebase for the pulse generation 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. You can program the CVS-1450 device to switch between up to 32 (2 inspection sequences for different parts on an assembly line.

)

Based on the input to the product selection port, you can configure the application software to run the appropriate inspection sequence. For example, an upstream CVS-1450 device programmed for part classification might drive the product selection port of a downstream CVS-1450 device. Alternatively, a PLC with information about which part is being inspected can drive the product selection port of the CVS-1450 device.

Using ISO Input 5 as a Latch

You can configure the product selection port to use ISO Input 5 as a latch. A rising edge on ISO Input 5 can latch the data into a data register on the CVS-1450 device. Before each inspection, the software checks the status of the product select inputs and reads the most recent value latched into the register.

Note In Vision Builder AI, ISO Input 5 is always designated as a latch.

Chapter 4 Digital I/O Functionality

Table 4-3 lists the product selection ports.

General-Purpose I/O

General-purpose inputs and outputs are available as both TTL and isolated connections. At any time, the software running on the CVS-1450 device can read the inputs and drive the outputs high or low.

General-Purpose Inputs

The primary difference between general-purpose inputs and trigger inputs is that you cannot use general-purpose inputs to initiate a timed pulse generator. In an application, use the general-purpose inputs to get the status of the inputs at a given point and not to synchronize the CVS-1450 device with an external event.

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

An example of how to use general-purpose inputs is reading the status of a general-purpose input as the first step in your inspection sequence and recording that value as part of your inspection.

General-Purpose Outputs

The primary difference between general-purpose outputs and timed pulse outputs is that the timing of general-purpose outputs is controlled by software rather than hardware. As a result, timing of general-purpose outputs changes as the inspection algorithm changes, which makes general-purpose outputs less appropriate than timed outputs for camera control, strobe light control, and other applications that require precise timing.

NI CVS-1450 Series User Manual 4-8 ni.com

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.

I/O for Fault Conditions

The CVS-1450 device recognizes the following fault conditions:

• External shutdown, when Shutdown mode is enabled

• Watchdog timer expiration

• Overheat

The behavior of the CVS-1450 device in the event of a fault condition is dependent on configuration settings of the SAFE MODE DIP switch and the software-enabled Shutdown mode. Table 4-4 summarizes how user configuration affects the behavior of the CVS-1450 device in the event of a fault condition. To resume operation, address the fault condition and reset the CVS-1450 device. The following sections describe each fault condition.

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. When this fault occurs, the POWER OK LED turns red and all system operation halts. To resume operation, you must reset the CVS-1450 device.

For all fault conditions, outputs operate according to user-defined shutdown states. Each TTL output is configurable to drive high, drive low, or 3-state, and each isolated output is on/off configurable.

Shutdown mode is unavailable when the SAFE MODE DIP switch is turned on.

Refer to Table 4-4 for a summary of how user configuration affects the shutdown condition.

Disabling Shutdown Mode

To disable Shutdown mode once it is enabled, remove Shutdown mode from the software script and reset the CVS-1450 device. To reset the system, press the RESET button on the CVS-1450 device front panel for at least two seconds.

Note For prototyping when equipment is unavailable, you can wire from Viso to

ISO Input 11 to simulate external equipment that indicates to the CVS-1450 device to operate normally.

Watchdog Timer

The watchdog timer is a software configurable feature that can monitor software on the CVS-1450 device and take action if the software is unresponsive. The millisecond counter on the watchdog timer is configurable up to 65,534 ms, in 1 ms increments, before it expires.

NI CVS-1450 Series User Manual 4-10 ni.com

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. The expiration signal that indicates an expired watchdog timer continues to assert until the watchdog timer is disarmed. Disarming the watchdog timer resets the I/O.

• TTL Output 0—This option outputs a signal on TTL Output 0. A

High on TTL Output 0 indicates that the watchdog timer has expired. Low indicates that it has not expired. If the watchdog timer has

expired, the expiration signal continues to assert until the watchdog timer is disarmed.

• System Shutdown—This option halts the CVS-1450 device operation and turns the POWER OK LED red. If Shutdown mode is enabled, the outputs go to the user-defined shutdown states.

Table 4-4 summarizes how user configuration affects the shutdown condition.

Overheat

Operating the CVS-1450 device outside of its temperature specifications may cause the CVS-1450 device to overheat. Refer to Appendix B,

Specifications, for temperature specifications.

In the event of an overheat, all CVS-1450 device operation halts and the POWER OK LED turns red. If Shutdown mode is enabled, the outputs go to the user-defined shutdown states.

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.

Caution Do not apply a voltage greater than 30 VDC to the isolated inputs. Doing so could

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.

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. Use a 75 Ω coaxial cable, such as RG-179, to connect to the SMB connectors.

Figure 4-8 shows connections to the 44-pin DSUB connector and the TRIG 0 SMB connector that minimize transmission line effects.

Typical System Setup

Digital I/O configuration varies depending on the number of cameras your system setup requires. You can access the digital I/O through the 44-pin DSUB connector or through the three SMB connectors.

The digital I/O capabilities of the SMB connectors on the CVS-1450 device are ideal for typical single-camera applications. The SMB connectors are labeled TRIG 0, TRIG 1, and TRIG 2.

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. Multiple CVS-1450 Devices Connected to the Same Network

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. This feature allows remote configuration, programming, and monitoring of any CVS-1450 device not protected by a firewall or user password.

Use the CVS-1450 device serial number and media access control (MAC) address to uniquely identify each unit. The serial number and MAC address are printed on the top side of each CVS-1450 device unit, as shown in Figure 5-2.

Figure 5-2. Serial Number and MAC Address Label on the CVS-1450 Device

The configuration environment on the host machine displays these values in order to distinguish one CVS-1450 device from another. In addition to distinguishing units based on serial number and MAC address, you can also assign each CVS-1450 device a descriptive name in the configuration environment.

When configured to run an inspection, the CVS-1450 device can run autonomously without connection to the host machine. All image acquisition, inspection, decision making, and I/O occurs on the CVS-1450 device itself. For local monitoring of the inspection, you can connect a monitor directly to the Video Out connector on the CVS-1450 device, as shown in Figure 5-3.

NI CVS-1450 Series User Manual 5-2 ni.com

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.

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. When you click Browse, the ACT/LINK LED on the CVS-1450 device should flash to indicate that communications are taking place.

• Certain network devices, such as switches and routers, may filter out the directed UDP broadcast packets the development computer uses to communicate with unconfigured CVS-1450 devices, even if these devices are on the same subnet. You can test this by connecting the development computer and the CVS-1450 device directly to a network port or by using a crossover cable between the CVS-1450 device and the development computer. If the CVS-1450 device appears in the software using this configuration, but not when connected to the larger network, the network is not properly communicating with the CVS-1450 device. Consult your network administrator.

• The CVS-1450 device may have been configured on another network and then moved to the current network. Reconfigure the CVS-1450 device on the current network.

• The grade of cable you are using may be insufficient for the speed of your network, or you may be using the wrong type of Ethernet cable. Use a straight-through cable when connecting to network hardware. Use a crossover cable to connect directly to the development computer.

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.

restart the device.

or Chapter 2, Setup and Configuration, of this manual for information about configuring the CVS-1450 device for your application.

– ISO Input 11 is used to indicate to the CVS-1450 device that all

external devices are ready for operation. When ISO Input 11 turns off, the NI 1450 shuts down. Either turn on ISO Input 11 with an external source and reset the CVS-1450 device, or disable Shutdown in the software.

Note For prototyping when external equipment is unavailable, Viso can be wired to

ISO Input 11 to turn on the CVS-1450 device.

• Watchdog timer expired while configured for the system shutdown option

– Determine if the interval between watchdog timer resets is

insufficient for the processing time. Check the software to determine if it could monopolize the processor.

• Processor overheat

– Make sure you are operating the CVS-1450 device in compliance

with the temperature specifications in Appendix B,

Specifications.

Refer to Table 4-4, Configuration Settings and Effects, for more information about fault conditions.

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.

Runaway Startup Application

If a runaway startup application causes the CVS-1450 device to become unresponsive, power off the CVS-1450 device and then restart it with either the NO APP switch or the SAFE MODE switch in the ON position. Restarting the CVS-1450 device with the NO APP switch enabled prevents any VIs from running at startup. Restarting with the SAFE MODE switch enabled starts the CVS-1450 device in Safe mode and does not launch the embedded LabVIEW RT engine. Refer to the DIP Switches section of Chapter 3, LEDs, DIP Switches, and Connectors, for more information about these DIP switches.

System Displays a Missing Operating System Error at Startup

The CVS-1450 device was powered on or reset with all DIP switches in the ON position. Set the DIP switches to the off position, and reset the CVS-1450 device by pressing the RESET button for at least two seconds.
