Electromagnetic and Electrostatic Interference Prevention

During installation and use of this product, high-voltage leakage must be avoided to prevent personal injury or equipment damage.

When using shielded cables, ensure the shielding layer is intact without damage and 360° crimped to the metal connector for conduction.
If this product is frequently powered on and off, be sure to strengthen voltage stabilization and isolation; a DC/DC isolated power module can be added between this product and the adapter.
Insulate unused cables of this product.
When installing this product, if you cannot ensure good grounding of the product itself and all connected equipment, choose insulated brackets to isolate this product.
The protective earths of all equipment must be bonded together and connected to protective earth at a single point to avoid voltage differences and interference loops caused by multiple grounding points.
When using custom network cables, ensure the shielding shell at the aviation connector is well bonded to the foil or braided shielding layer.
The product’s control lines and the industrial light source power lines should be routed separately; avoid bundling them together.
Route the product’s power cable separately from data and signal cables; if metal cable trays are used for separate routing, ensure the trays are well grounded.
Do not share wiring with other products (especially servo motors or high-power equipment); the spacing between routes should be ≥10cm. If unavoidable, implement proper shielding on the cables.
Keep power and network cables away from high-current, high-voltage, or frequently switching devices (such as stepper motors and solenoid valves) to avoid interference coupling.
When using centralized power supply, use a line filter to filter the product’s main power separately before use, or use a power adapter to supply the product independently.
The switching power supply that powers this product and the PC’s AC power should come from the same AC power strip; the protective earth can be shared to avoid multiple grounding points. Do not power high-power electromechanical equipment directly from this AC source.

Other on-site products (such as machines, internal components, etc.) and metal brackets must be correctly grounded to avoid static accumulation.
Use high-quality SSTP shielded network cables. Under the premise of meeting usage requirements, do not overly pursue cable flexibility, so as not to compromise the conductor, shielding layer, or jacket and reduce anti-interference capability.
Shielded cables can be used for power control lines and avoid coiling; magnetic rings can be added to the product’s power control lines to absorb electromagnetic interference signals.
When the product’s cables are excessively long, bundle them in a figure-8 shape; route the excess in back-and-forth bends, avoiding loops, to reduce electromagnetic interference coupling.
Power cables and network cables can be routed in parallel, but must not be entwined together.
During wiring, reasonably assess routing space; do not pull cables forcefully to avoid damaging electrical performance.
When connecting this product to metal accessories, ensure reliable contact to maintain good conductivity.
Install the product and cables as far as possible from equipment that may generate sparks (such as brushed motors and relays); add metal shielding enclosures if necessary.

Maintain appropriate ambient humidity; wear an anti-static wrist strap during operation, wear anti-static clothing and shoes, and use conductive materials for mounting surfaces to reduce electrostatic discharge (ESD) risk.

The above values are typical measurements at an ambient temperature of 25°C; individual differences exist between cameras.

The relationship between input signal amplitude and delay for the opto-isolated input interface is shown in the table below:

Input signal amplitude (Vp-p)	Rising-edge trigger delay tDR (µs)	Falling-edge trigger delay tDF (µs)
3.3	3.99	20.80
5	3.80	21.16
9	3.61	21.47

Rising-edge trigger delay is the time from 90% of the external input signal amplitude to 90% of the signal amplitude at the FPGA input pin.
Falling-edge trigger delay is the time from 10% of the external input signal amplitude to 10% of the signal amplitude at the FPGA input pin.
Trigger input delay measures the latency from the external opto-isolated input port to the FPGA input pin; it does not include FPGA internal logic delay or sensor internal trigger circuit delay.
For the opto-isolated input interface circuit, with a pulse amplitude of 3.3 V, the shortest measured positive input pulse width is 1.02 μs, and the shortest measured negative input pulse width is 20.97 μs.
The above values are typical measurements at an ambient temperature of 25°C; variations exist between individual cameras and across operating temperatures of the same camera.

Do not apply voltages exceeding the rated values to the input terminals.
If a fuse blows due to overvoltage or other abnormal conditions, please contact technical support. Do not replace the interface fuse yourself.

Output Delay vs. External Power Supply Voltage

In some applications a pull-up resistor to an external supply is required to produce a high-level output. The pull-up resistor value depends on the external device and application scenario, but must not exceed the maximum allowable current of the opto-isolated output port. The larger the pull-up resistor value, the smaller the optocoupler conduction voltage drop; the longer the output waveform rise/fall time; and the smaller the external drive capability. The maximum current of the opto-isolated output is 50 mA, and the timing diagram of the opto-isolated output signal delay is shown below.

Recommended pull-up resistor values under different external supply voltages are as follows: 1 kΩ for 3.3 V or 5 V supply; 2.4 kΩ for 12 V supply; 4.7 kΩ for 24 V supply.

When using a 1 kΩ pull-up resistor, the output rise/fall time and rising/falling edge delay time under different external supply voltages are shown in the table below.

External supply voltage (V)	Rise time tR (µs)	Fall time tF (µs)	Rising-edge trigger delay tDR (µs)	Falling-edge trigger delay tDF (µs)
5	19.70	3.20	39.9	8.06
12	24.06	5.22	44.8	11.8
24	30.11	8.10	44.8	53.2

Output delay measures the latency from the FPGA output pin to the opto-isolated output pin; FPGA internal logic delay is not considered.
Rise time is the time for the output pulse to rise from 10% to 90%; fall time is the time to drop from 90% to 10%.
Rising-edge trigger delay is the time from 10% of internal logic to 90% of the output pulse; falling-edge trigger delay is the time from 90% of internal logic to 10% of the output pulse.
The above values are typical measurements at an ambient temperature of 25°C; individual differences exist across temperatures and between cameras.

Output Conduction Voltage Drop vs. Output Current

The relationship between opto-isolated output conduction voltage drop and output current is shown below.

opto output characteristic curve area scan

The conduction voltage drop is the voltage difference between OPT_OUT (LINE0) and OPT_GND when the optocoupler is conducting.
The maximum conduction voltage drop at the opto output end is about 2.35 V (measured at 100 mA output current).
The above values are typical measurements at an ambient temperature of 25°C; variations exist between individual cameras and across operating temperatures of the same camera.

Optocoupler Interface as Transistor Output

The camera’s transistor output is isolated from internal circuits via an optocoupler, therefore the transistor output can be used as NPN or PNP output. When used as PNP output, opto input LINE1 is not available. The connection methods for the opto interface as NPN output and as PNP output are shown below.

The maximum allowable continuous output current at the opto-isolated output port is 50 mA. Do not apply voltages or loads that exceed its maximum switching capacity to the output terminals.
If the fuse blows due to a short circuit or other overcurrent condition, please contact technical support. Do not replace the interface fuse yourself.
When using the camera’s output interface to drive inductive loads (such as relays), you must choose a relay with a built-in flyback diode or add a flyback diode in the external circuit. Otherwise the output interface may be damaged by overvoltage. The figure below shows an example DC inductive load suppression circuit. In most applications, using only the additional diode A is sufficient; if a higher turn-off speed is required, it is recommended to also add Zener diode B. Ensure the selected Zener diode can satisfy the current and power requirements of the output circuit.

When using the camera’s opto output to connect a tungsten filament lamp load, avoid direct connection. A tungsten filament lamp generates an inrush current about 10 to 15 times the steady-state current at turn-on, which may exceed the maximum allowable current of the opto-isolated output, leading to damage to the output interface. It is recommended to isolate and protect it via a replaceable plug-in interposing relay or by adding an inrush current limiter in the circuit.
