Getting Started with the NI PCIe-1429 and NI PCIe-1430
5.
Right-click
Port 0
or
Port 1
and select
Camera
.
6.
Select your camera from the menu. If your camera is not in the menu, verify that the appropriate
camera file is installed in the
<NI-IMAQ>\Data
directory.
Note
If you lose communication with the camera during an acquisition for any reason, such as
unplugging a cable or powering off your camera, you must restart the acquisition to allow the device
to relock the incoming timing signals.
Note
The NI 1429 and NI 1430 are each equipped with a temperature monitor. The device will stop
acquiring images if it reaches its maximum allowable temperature. An error will occur, reporting that
the maximum temperature has been reached.
Specifications
The following specifications apply to the NI 1429 and NI 1430 image acquisition devices. These
specifications are typical at 25 °C, unless otherwise stated.
External Connections
Number of external trigger I/O lines......................1
Note
External TTL lines on the 15-pin D-SUB connector become unavailable when the trigger
source is set as an optically isolated input or an RS-422 input in MAX.
External trigger lines
Voltage range .................................................0 V to 5 V (TTL)
V
IH
min ..................................................2.0 V
V
IL
max ..................................................0.8 V
V
OH
min .................................................2.4 V at 8 mA source
V
OL
max .................................................0.55 V at 8 mA sink
Polarity...........................................................Programmable, active high or active low
Power-on state........................................................Input (high-impedance) 22.1 k
Ω
pull-down to
ground
Camera interface ....................................................Camera Link 1.1
Clocks
Pixel clock frequency range...................................20 MHz to 85 MHz
1
Note
The Camera Link specification requires cameras to transmit at a minimum of 20 MHz.
PCI Express Interface
PCI Express compliance ........................................Version 1.0a
Native link width....................................................x4
Up-plugging link width availability.......................x8, x16
Note
Some system devices limit data transfer rates for plug-in devices in an up-plugging
configuration. Refer to the documentation provided by your computer manufacturer to determine
if your computer will support a x4 plug-in device at a x4 data rate in a larger slot.
1
This value corresponds to the serialized Camera Link cable transmission rate of 140 to 595 MHz.
