Spectral Response#

onsemi MT9P031 Spectral Response

The spectral response curve excludes lens characteristics, light source characteristics, and IR cut filter characteristics.

IR Cut Filter#

To achieve best camera performance, Basler recommends using a dielectric IR cut filter.

The filter should transmit in a range from 400–≈700 nm, and it should cut off from ≈700–1100 nm.

  • For the bare board variant, Basler recommends installing an IR cut filter or a lens with an integrated IR cut filter.
  • For the S-mount variant, Basler recommends attaching a lens with an integrated IR cut filter to the camera.
  • On the CS-mount variant, a suitable IR cut filter is already built into the lens adapter (see below).

Integrated IR Cut Filter (CS-Mount Variants Only)#

Basler dart CS-mount color cameras are equipped with an IR cut filter. The filter is mounted in a filter holder inside the lens mount.

The IR cut filter is manufactured by Fujita Electric Works Ltd. and has the following spectral characteristics:

Wavelength [nm] Transmittance
420–600 Tmin ≥ 90 %
Tavg ≥ 92%
650 ± 10 T = 50 %
700–1000 Tavg ≤ 1 %
1000–1100 Tavg ≤ 5 %

Info

On daA1600-60um/uc camera models, side-fill material (Loctite E1172A 15G) is injected beneath the sensor. The side-fill material is visible around the sensor. This material optimizes the mechanical robustness of the camera and does not impair camera operation.

Electrical Requirements#

WARNING – Electric Shock Hazard

Unapproved power supplies may cause electric shock. Serious injury or death may occur.

  • You must use power supplies that meet the Safety Extra Low Voltage (SELV) and Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the SELV and LPS requirements.
WARNING – Fire Hazard

Unapproved power supplies may cause fire and burns.

  • You must use power supplies that meet the Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the LPS requirements.
NOTICE – Incorrect voltage can damage the camera module.

You must supply camera and I/O power within the safe operating voltage ranges specified below.

Camera Power#

You must supply camera power that complies with the Universal Serial Bus 3.0 specification.

The nominal operating voltage is 5 VDC, effective on the camera module's connector.

General Purpose I/O Lines#

The camera module has two direct-coupled GPIO lines that are accessed via contact 3 and 4 of the I/O connector on the back of the board.

The GPIO lines have the following characteristics:

  • They can be configured to operate as inputs or outputs.
  • They are called line 1 and line 2.
  • They are directly connected to the FPGA (unbuffered, see circuit diagram). Therefore, they are not protected against overcurrent or overvoltage.
  • They are on the same electrical potential as the circuit board.
  • They are compatible with low-voltage TTL (LVTTL) signals. To make the camera module compatible with standard TTL signals, attach the optional dart I/O board.
  • They are protected against electrostatic discharge (ESD) strikes of up to 2 kV (contact discharge). The tests were performed according to the EN61000-4-2 standard.
  • By default, they are configured as input lines. Due to their high impedance, inputs are susceptible to noise and electromagnetic interference (EMI). For long cables or in harsh electromagnetic environments, the use of active converter circuits may be necessary.

If you require a specific output logic level at all times, add a suitable pull-up or pull-down resistor. If you use a pull-down resistor, the resistor value should be 1.8 kΩ or greater so that the current limit is not exceeded.

NOTICE – Applying incorrect electrical signals to the GPIO lines may severely damage the camera module.

Before you connect any external circuitry to the GPIO lines, use the Line Mode feature to configure the line as an input or output line.

If a GPIO line is configured as an output line, never short-circuit the line.

Before you apply signals to the GPIO lines, connect the camera module to a USB port.

Make sure to apply appropriate input or output signal voltages as specified below.

Operation as Input#
Voltage Description
4.2 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–3.4 VDC Safe operating range. The minimum external pull-up voltage is 3.3 VDC.
0–0.7 VDC Indicates a logical 0 (with inverter disabled).
1.8–3.4 VDC Indicates a logical 1 (with inverter disabled).
  • Maximum input leakage current: 10 μA
  • Internal pull-up resistor: 25 kΩ typical, 7 to 41 kΩ.
  • To increase the voltage allowed on the I/O input lines, attach the optional dart I/O board. The I/O board makes the camera module compatible with TTL input signals.
Operation as Output#
Voltage Description
3.4 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–0.5 VDC Indicates a logical 0 (with inverter disabled).
2.4–3.3 VDC Indicates a logical 1 (with inverter disabled).

Maximum current allowed through the output circuit: 2 mA

For more information about the I/O lines, see the I/O Control section.

Circuit Diagrams#

Cable Requirements#

USB 3.0 Cable#

  • Use a high-quality USB 3.0 cable with a USB 3.0 Micro-B plug.

  • Do not use cables with a USB 1.x/2.0 Micro-B cable plug, even if you are connecting the camera module to a USB 2.0 port. Otherwise, the module may not work properly.

    Cable Recommendation

  • To avoid EMI, cables must be shielded, as specified in the USB 3.0 standard.

  • Basler recommends using USB 3.0 cables from the Basler cable portfolio.

For more information, see the Recommended Accessories for Basler USB 3.0 Cameras document.

I/O Cable#

  • The camera-side connector must be terminated with a 1.27 mm pitch dual-row plug. If you need other I/O connectors, use the dart I/O board.
  • The cable must be wired to conform with the pin assignments shown below.

USB 2.0 Compatibility#

This camera module is USB 2.0 backward compatible. However, performance is limited when connected to a USB 2.0 port:

  • In order to handle the lower USB 2.0 bandwidth, the DeviceLinkThroughputLimit parameter value is set to 32 000 000 (32 MByte/s).
  • This reduces the maximum possible frame rate.
  • This also affects other aspects of the performance, e.g., the sensor readout time, trigger delay, jitter, or the precision of the exposure time set.
  • If you operate a daA1280-54um/uc camera module on a USB 2.0 port, image noise may increase. This is because the image sensor produces more image noise at low frame rates. To reduce image noise at low frame rates, try the following:

For information about suitable USB 2.0 host controllers and about optimizing the USB 2.0 data transmission rate, see the Recommended USB 2.0 Host Controllers for Basler dart and pulse Cameras application note.

Physical Interface#

Connectors and Status LED#

Camera Connectors and LED Indicator

I/O Connector#

6-pin socket connector with a 1.27-mm pitch dual-row receptacle. Provides access to the I/O lines.

USB 3.0 Connector#

Camera USB 3.0 Connector

The camera module's USB 3.0 connector is a standard Micro-B USB 3.0 connector. It provides a nominal 5 Gbit/s SuperSpeed data transfer connection to supply power to the device and to transmit video data and control signals.

Connection assignments and numbering adhere to the Universal Serial Bus 3.0 standard. The recommended mating connector is any standard Micro-B USB 3.0 plug.

Depending on how you integrate the Basler dart into your system, you must select a corresponding USB 3.0 connector that matches the orientation of the dart USB 3.0 connector in the mounted position. The orientation of the USB 3.0 connector is shown in the figure above.

Status LED#

Indicates operation:

  • LED is blinking slowly: Device is being configured.
  • LED is lit permanently: Device is configured and operative.
  • LED is blinking rapidly: Internal error.

The LED can be turned off permanently by setting the DeviceIndicatorMode parameter to Inactive.

I/O Board#

The dart I/O board is available from Basler. It has the following benefits:

  • Offers additional I/O connectors instead of the single standard I/O connector.
  • Increases the voltage allowed on the I/O input lines (TTL compatibility).
  • Allows you to trigger multiple dart USB 3.0 camera modules simultaneously.
  • Protects the camera module against short circuits.

The board can be mounted on the back of the Basler dart circuit board. The connectors of the I/O board replace the standard I/O connector.

Contact your Basler sales representative to order the dart I/O board.
