About the NI CVS-1459
The NI CVS-1459 is a compact vision system that acquires, processes, and displays images
from USB3 Vision cameras. The NI CVS-1459 provides multiple digital input/output (I/O)
options for communicating with external devices to configure and start an inspection and to
indicate results.
Hardware Overview
The NI CVS-1459 front panel consists of a VGA connector, RJ50 serial port, two USB 2.0
ports, a 10/100/1000 Ethernet connector, and two USB3 Vision ports.
The NI CVS-1459 front panel also includes LEDs for communicating system status and a 44pin Digital I/O port. The Digital I/O port offers 8 isolated inputs, 8 isolated outputs, 2
bidirectional differential I/O (RS-422) or single-ended input lines that can be used with a
quadrature encoder, and 8 bidirectional TTL lines.

Ethernet Port
The Ethernet port on the NI CVS-1459 provides a connection between the NI CVS-1459 and a
network. The NI CVS-1459 automatically detects the speed of the connection and configures
itself accordingly.
A CAT 5e or CAT 6 1000Base-T Ethernet cable is required to achieve 1,000 Mbps (Gigabit)
Ethernet performance. CAT 5e and CAT 6 Ethernet cables are not guaranteed to meet the
necessary requirements. While CAT 5 cables may appear to work at 1,000 Mbps. CAT 5 cables
can cause bit errors, resulting in degraded or unreliable network performance.

RS-485/422/232 Serial Port
The NI CVS-1459 has a single serial port that can operate in either RS-485/422 mode or
RS-232 mode. Set the serial port mode in the BIOS.
The serial port is a 10-position RJ50 modular jack, which can connect to serial devices, such
as PLCs, scanners, and lighting devices.

Using the Serial Port in Windows
The default serial communications driver for Windows is installed on the NI CVS-1459. The
serial port appears in the operating system as COM2. This driver is provided by Microsoft
with all Windows installations.
Use the default serial driver when the serial port is configured to RS-232 mode in the BIOS.
The default serial driver can also be used when the serial port is configured to RS-485 in FourWire or Auto wire modes.
The default serial driver does not allow the wire mode to be changed at run time and it does
not allow the RS-485 transceivers to be controlled manually. For full control of the RS-485
serial port, the NI-Serial for Windows driver must be installed. The serial mode, whether
RS-232 or RS-485, must be configured in the BIOS regardless of the driver used.
Refer to the National Instruments website at ni.com to download NI-Serial. Install NI-Serial
15.0 or later.
VGA Port
Use the VGA port to connect a monitor to the NI CVS-1459. Use any standard 15-pin VGA
cable to access the VGA port. The VGA port has a maximum resolution of 1920 x 1200 at
60 Hz.

Digital I/O Port
The 44-pin Digital I/O port on the NI CVS-1459 offers 8 isolated inputs, 8 isolated outputs, 2
bidirectional differential I/O (RS-422) or single ended input lines which can be used with a
quadrature encoder, and 8 bidirectional TTL lines. The Digital I/O port can be connected to
any appropriate shielded device or connector block using a shielded cable. Refer to the
following image and table for pin locations and functions.
