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 four direct-coupled GPIO lines that are accessed via contacts 3, 4, 5, and 6 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, Line 2, Line 3, and Line 4.
  • 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.
  • 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.
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#

→ See Circuit Diagrams.

Cable Requirements#

USB 3.0 Cable#

  • Use a high-quality USB 3.0 cable with a USB 3.0 Micro-B plug.
  • 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.
  • The cable must be wired to conform with the pin assignments shown below.

USB 3.0 Compatibility#

Info

This camera module is not USB 2.0 compatible. It won't work when connected to a USB 2.0 port.

NOTICE – Unsuitable USB 3.0 components or bandwidth settings may impair the camera's performance.

  • Use high-quality USB 3.0 components only. Otherwise, due to bandwidth limitations, performance may be reduced and frames may be corrupt or dropped.
    • Basler strongly recommends using only accessories available from Basler. These have been thoroughly tested for optimum performance.
    • If possible, use only one camera per USB 3.0 host controller.
    • For more information, see the Recommended Accessories for Basler USB 3.0 Cameras document.
    • If you can't use suitable USB 3.0 components, decrease the value of the DeviceLinkThroughputLimit parameter. However, this will reduce the camera's frame rate.
  • The camera's performance is affected by certain bandwidth settings. The following problems are common:
    • Corrupt or dropped frames may occur if the DeviceLinkThroughputLimit parameter is too high.
    • On rolling shutter cameras, image distortion (increased rolling shutter effect) may occur if the DeviceLinkThroughputLimit parameter is too low.
    • The camera's frame rate may be reduced significantly if the MaxTransferSize parameter is too low.

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 camera operation (LED lit = camera operating).

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