Variants
The daA1280-54um camera is available in the following variants:
Bare board: Consists of a circuit board only.
S-mount: Consists of a circuit board and a camera front. S-mount lenses can be
mounted in the lens mount on the camera front.
CS-mount: Consists of a circuit board and a camera front. CS-mount lenses can be
mounted in the lens mount on the camera front.
Basler dart S-mount color cameras are not equipped with an IR cut lter. If
you want to operate a Basler dart S-mount color camera with an IR cut
lter, you must attach a lens with an integrated IR cut lter to the camera.

Electrical Requirements
DANGER
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 re 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
Voltage outside of the specied range can damage the camera.
You must supply camera and I/O power within the safe operating voltage ranges
specied below.

https://docs.baslerweb.com/?filter=Camera:acA2500-14gm#t=en%2Fdaa1280-54um.htm 7/11
You must supply camera power that complies with the Universal Serial Bus 3.0
specication.
The camera’s nominal operating voltage is 5 VDC, effective on the camera’s connector.
General Purpose I/O Lines
The camera 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 congured to operate as camera inputs or camera 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
compatible with standard TTL signals, attach the optional dart I/O board to the
camera.
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 congured 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 specic 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 camera’s GPIO line can severely
damage the camera.
Before you connect any external circuitry to the GPIO line, use the Line Mode
parameter to congure the line as an input or output line.
Make sure to apply appropriate input or output signal voltages as specied below.
Before you apply signals to the GPIO lines, connect the camera to a USB port.
If a GPIO line is congured as an output line, never short-circuit the line.
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.

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 to the camera. The I/O board makes the camera 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

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 to a USB 2.0 port. Otherwise, the camera may not work properly.
To avoid EMI, cables must be shielded, as specied in the USB 3.0 standard.
Basler recommends using USB 3.0 cables from the Basler Vision Components
range.
For more information, see the Recommended Accessories for Basler USB 3.0 Cameras
document.

https://docs.baslerweb.com/?filter=Camera:acA2500-14gm#t=en%2Fdaa1280-54um.htm 9/11
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.
Basler recommends using I/O cables from the Basler Vision Components range.
USB 2.0 Compatibility
All Basler dart USB 3.0 cameras are USB 2.0 backward compatible.
However, camera 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 camera's maximum possible frame rate.
This also affects other aspects of the camera 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 on a USB 2.0 port, image noise may
increase. This is because the image sensor of the camera produces more image
noise at low frame rates. To reduce image noise at low frame rates, try the
following:
Disable free run image acquisition and use triggered image acquisition instead.
Disable overlapping image acquisition by setting the OverlapMode parameter
to Off.
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.

Indicates camera operation:
LED is blinking slowly: Camera is being congured.
LED is lit permanently: Camera is congured and operative.
LED is blinking rapidly: Internal error.
The LED can be turned off permanently by setting the DeviceIndicatorM
ode parameter to Inactive.
USB 3.0 Connector
The camera's USB 3.0 connector is a standard Micro-B USB 3.0 connector. It provides a
USB 3.0 connection to supply power to the camera 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 gure above.

The dart I/O board is available from Basler. It has the following benets:
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 cameras simultaneously.
Protects the dart camera 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 of the Basler dart.
