OPTO Trigger 5#

What is OPTO Trigger 5?#

OPTO Trigger 5

  • is a trigger extension board that can be used together with all frame grabbers of the microEnable IV, microEnable 5 marathon and microEnable 5 ironman series.a
  • offers 16 OPTO-coupled (galvanically isolated) trigger signals for controlling cameras and peripheral devices. Its signals can be adapted to the industrial signal level (typically 5 VDC – 24 VDC).
  • allows to synchronize multiple frame grabbers.
  • is configurable and can replace any of the 6 flavors of its predecessor Basler OPTO trigger board IV.

OPTO Trigger 5 is connected to the frame grabber via a 34-pin flat cable:

  • You can configure the IN pins of port B to receive single-ended or differential incoming signals.
  • You can configure if you want to use the IN pins of both ports in pull-up or pull-down mode.
  • You can configure if the outgoing signals are inverted or not.

For details on configuring OPTO Trigger 5, refer to the Configuring the Physical Interface section.

For information which signals are received by OPTO Trigger 5 via the flat cable, see Flat Cable Pinout.

Installing the Trigger Extension Board#

Info

Before installation, check if the DIP switches on OPTO Trigger 5 are easily available after installation. If not, Basler recommends you to first set the DIP switches before installing OPTO Trigger 5 into the host PC. For information on how you use the DIP switches for configuration, see Configuration Options.

Info

Make sure you use an adequate ventilation system within your computer. This is of special importance if

  • there is little space between boards in a multi-board installation,
  • an installation is close to a graphics card.

Basler recommends leaving enough free space between boards.

You need the following components:

  • One microEnable frame grabber board
  • One trigger extension board
  • One 34-pin flat cable you received from Basler

To install your trigger extension board:

  1. Shut down the host PC.
  2. Unplug the host PC from the power outlet.
  3. Plug the trigger board into an empty slot on the slot bracket of the host PC. Frame grabber and empty slots in host PC Frame grabber and trigger board in host PC
  4. Fasten the trigger board to the PC chassis by screws.
  5. Connect the trigger board with the GPIO socket of your microEnable frame grabber board, using the 34-pin flat cable. Frame grabber and trigger board connected by flat cable
  6. Reboot your host PC.

Now, the trigger board is ready for use.

Info

For information how you can use multiple microEnable frame grabber boards with one trigger board or vice versa, see Using Multiple Boards.

Info

The power must be delivered by an external power source.

Info

The input signals are not directly passed to the opto couplers but send to differential comparators. The advantage is that the input accepts low current, voltage driven signals between 5 and 25 VDC. (Input signals can have pull up or a pull down resistor of 10 k Ohm). The polarity of the input signals is NOT inverted.

Info

On OPTO Trigger 5, the opto-couplers do not directly connect to the output, but are buffered by MOSFET transistors. These transistors build an easy-to-use open collector driver with a 20 mA static current diode as pull-up.

Configuring the Physical Interface#

You can configure various parameters that allow you to use OPTO Trigger 5 in different operation modes:

  • You can configure the IN pins of port A to receive single-ended or differential incoming signals.
  • You can configure the IN pins of port B to receive single-ended or differential incoming signals.
  • You can configure if you want to use the IN pins of both ports in pull-up or pull-down mode.
  • You can configure if the outgoing signals are inverted or not.

You set the individual parameters via the DIP switches located directly on the trigger board.

Info

When connected to microEnable 5 marathon Frame Grabbers, the configuration can be programmed by software using the command line tool gpiotool.exe see Configuration via Software. Programming by software overrides the DIP switch setting.

The LEDs on the board inform you which settings are active.

LEDs on the Board

Info

The software configuration always overrides the position of the DIP switches. Therefore, the position of the DIP switches on the board may not represent the actual setting. To know which settings are active, always rely on the LEDs.

Default Settings#

On delivery, the default settings are active. All DIP switches on OPTO Trigger 5 are OFF. All LEDs are OFF.

The default settings for the OPTO trigger board are the following ones:

  • Port A receives 4 single-ended incoming signals.
  • Port B receives 4 single-ended incoming signals.
  • The trigger board is in pull-up mode.
  • The outgoing signals are not inverted.

In default setting, the four LEDs are set to OFF:

Default Settings

Single Ended / Differential IN Signals#

You can configure the IN pins of Opto Trigger 5 in one of the four following ways:

  • all IN pins of port A and B receive single ended inputs (= 8 single-ended IN signals):

all IN pins of port A and B receive single ended inputs

This is the default setting. The DIP switches for Port A (switch 1) and B (switch 2) are in OFF position. The LEDs for port A (A DS) and port B (B DS) are OFF:

DIP Switches

  • all IN pins of port A and B receive differential inputs (= 4 differential IN signals, i.e., 4 pairs):

all IN pins of port A and B receive differential inputs

The DIP switches for port A (switch 1) and B (switch 2) are in ON position. The LEDs for port A (A DS) and B (B DS) are ON:

The DIP switch for port A (switch 1) is in ON position. The LED for port A (A DS) is ON . The DIP switch for port B (switch 2) is in OFF position. The LED for port B (B DS) is OFF:

DIP Switches

Pull Up / Pull Down#

You can configure OPTO Trigger 5 according to the electrical source of the incoming signal:

  • Use pull-up (10 kΩ) to receive signals from NPN transistors (open collector, open drain).
  • Use pull-down (10 kΩ) to receive signals from PNP transistors (open emitter, open source).

In most application scenarious, you will need to configure OPTO trigger 5 to pull-up .

Pull-up variant

Pull-up is the default setting. The DIP switch for transistor mode (switch 3) is in OFF position. The LED P DN is OFF:

Pull-up

Pull-down variant

Pull-down

Inverted / Not Inverted OUT Signals#

You can configure the OUT pins of the trigger board to send the outgoing trigger signals in inverted mode.

Not inverted

Not inverted is the default setting. The DIP switch for the inversion mode (switch 4) is in OFF position. The LED O INV is OFF:

Not inverted

Inverted

The DIP switch for the inversion mode (switch 4) is in ON position. The LED O INV is ON:

Inverted

Configuration via Software#

If you use OPTO Trigger 5 together with microEnable 5 marathon, you can - as an alternative to the DIP switches - use software to configure the physical interface of OPTO Trigger 5. This is especially helpful if you want to test OPTO Trigger 5 under laboratory conditions.

As soon as you configure OPTO trigger 5 via software, the position of the DIP switches does not provide any information about the actual configuration.

However, the LEDs on Opto Trigger 5 always inform you which setting is activeb. In addition, you can use the software to get information about the current settings.

Info

If you configure the physical interface of the trigger board via Software, the DIP switch position has no effect on the actual physical interface of the trigger board. How to reset the trigger board to read the DIP position for configuration of its physical interface, see Re-Enabling DIP Switch Configuration.

Configuration via Command Line#

For configuring the physical interface of Opto Trigger 5 via command line, you work with the gpioTool which comes as part of the Basler runtime environment.

Info

If you configure the physical interface of the trigger board via Software, the DIP switch position has no effect on the actual physical interface of the trigger board. How to reset the trigger board to read the DIP position for configuration of its physical interface, see Re-Enabling DIP Switch Configuration.

Configuring GPIO Banks on a Frame Grabber#

To configure a GPIO unit via command line:

  1. Open the command line window:

    Command Line Window

  2. In the command line tool, go to the bin directory of your runtime installation: cd /D %SISODIR5%\bin.

  3. Now, enter your commands and values as described in the following.

You have the following commands and parameters available:

gpioTool -b
-g
-s < bank >:< settings >
-h
-v

Commands

  • With command gpioTool -b you specify which frame grabber board in your system you want to address. Specifying the addressed board ins mandatory.
  • Via command gpioTool -b <board_index> -g you get the current GPIO bank settings of the specified frame grabber board displayed directly in the command line window.
  • Via command gpioTool -b <board_index> -s <bank>:<settings> you configure a specific GPIO bank on the specified frame grabber board.
  • Via command gpioTool -h you get help instructions displayed directly in the command line window.
  • Via command gpioTool -b <board_index> -v you get verbose output displayed directly in the command line window.

Value Ranges

  • :Index of the frame grabber board you want to configure. The value range depends on the number of frame grabbers you have installed in your system. When you are configuring a trigger extension board, you need to specify the frame grabber the trigger extension board is connected to.
  • bank: The bank defines which GPIO bank on the frame grabber board/trigger extension board you want to address. You have the following values available:
Value Addressed GPIO Bank
0 Front GPIO
1 GPIO on LightBridge / Port A on external trigger extension board
2 Port B on external trigger extension board
all Addresses all GPIO banks of the selected frame grabber. When working with LightBridge, all addresses the Front GPIO and the GPIO. With marathon, all addresses the front GPIO and both ports of the trigger extension board.
  • settings: You set here the values for three parameters, separated by comma. settings is in the form signal,pull-up-down, inversion.

  • signal is either "ds" or "se" (GPIs receive differential or single-ended signals)

  • pull-up-down is either "pu" or "pd" (pupull-up or pull-down)
  • inversion is either "in" or "ni" (inverted or not-inverted)
Parameter Value Effect of specific value
signal se You set all addressed GPIs to receive single-ended signals.
signal ds You set all addressed GPIs to receive differential signals.
pull-up-down pu You set to pull-up mode.
pull-up-down pd You set to pull-down mode.
inversion ni GPOs are not inverted.
inversion in GPOs are inverted.

Example:

  • C:\Users\nameofuser>cd /D %SISODIR5\bin
  • C:\SiliconSoftware\Runtime5.4.1\bin>gpioTool -b 0 -s 0:ds,pu,ni

Explanation

a. In the first line of the example, you go into the bin directory of your Basler runtime installation.

In the second line:

b. You call the GPIO configuration tool via gpioTool. c. You specify which frame grabber board in your system you want to configure. When you are configuring a trigger extension board, specify the frame grabber the trigger exension board is connected to. You first enter -b to say that the next input will be the board index of the frame grabber board. Then you enter the index number of the frame grabber you want to configure {0, 1, 2 …}. If you have only one frame grabber board in your system, the board index is 0. In our example, you want to configure GPIOs on frame grabber 0. Specifying the frame grabber index is mandatory. d. With -s you announce that you are now starting the actual configuration. e. With the value that follows {0,1,2,all} you specify which GPIO bank on the selected frame grabber/trigger extension board you are going to configure. In the example, you selected the Front GPIO (0). f. With double dot: you separate the specification of the addressed GPIO bank and the actual configuration values. g. After the double dot you specify the values for the three parameters. In the example, the Front GPIO is configured to receive two differential IN signals (ds), to work in pull-up mode (pu), and to send the outgoing signals not inverted (ni).

Re-Enabling DIP Switch Configuration#

Info

If you re-set the GPIO banks on a frame grabber board to be configured per DIP switch position on Opto Trigger 5, the configuration you entered via Software will no longer be effective.

To re-enable the configuration via DIP switches:

  1. Open the command line window:

    Command Line Window

  2. In the command line tool, go to the bin directory of your runtime installation: cd /D %SISODIR5%\bin

  3. Now, enter the following string: installdir\bin>gpioTool -b -s < bank >:dip-switch

Re-Setting Default Values#
  1. Open the command line window:

    Command Line Window

  2. In the command line tool, go to the bin directory of your runtime installation: cd /D %SISODIR5%\bin

  3. Now, enter the following string: installdir\bin>gpioTool -b -s < bank >:default

LED Behaviour#

LED Label LED not active LED active
A DS Port A receives 4 single-ended incoming signals. Port A receives 2 differential incoming signals.
B DS Port B receives 4 single-ended incoming signals. Port B receives 2 differential incoming signals.
P DN Trigger board is in pull-up mode. Trigger board is in pull-down mode.
O INV The outgoing signals are not inverted. The outgoing signals are inverted.

Examples:

  1. Default setting: The four LEDs on the OPTO trigger board are not active:

Other Combination

Info

The LEDs always show the actual setting of the parameter, no matter if the parameter has been set via DIP switch or via software.

Electrical Characteristics#

There are three different power/ground systems on OPTO Trigger 5. One supplies the signals of the port A connector, another one the signals of the port B connector, and the third one the signals of the flat cable connector. There is no electrical connection between these three power/ground systems.

Each of the three power/ground systems may have a different supply voltage. The voltage range lies between 5 and 25.0 VDC. The signal voltage is defined by the supply voltage for both, input and outputs. See below for details on the electrical characteristics.

The following data apply to the physical input and output ports of both ports, port A and port B.

Inputs#

Min Typical Max Unit
Supply Voltage 4.5 VDC 28 VDC V
Input Threshold 20% Supply Voltage V
Differential Input
Offset Voltage
10 mV mV
Input Current 4 mA (per channel)

Info

The input signals are not directly passed to the opto couplers but send to differential comparators. The advantage is that the input accepts low current, voltage driven signals between 5 and 25 VDC. (Input signals can have pull up or a pull down resistor of 10k Ohm). The polarity of the input signals is NOT inverted.

Info

OPTO Trigger 5 has been designed with a varistor which opens at an input voltage of 30V to let the onboard surge protector get active to protect the board. At a total supply voltage of 36V, the electronic chips will become defective.

Outputs#

Min Typical Max Unit
Supply Voltage
(max. supply current per port)
4.5 VDC 28 VDC V
Output Signal Voltage High -0.3 VDC Supply Voltage V
Output Signal Voltage Low 0.3 mV
Output Current 20 mA (per channel)

The supply current required for each port of OPTO Trigger 5 depends on the number of used inputs and outputs, the signal and the voltage level. Typical supply current required per port: < 200 mA/port

Info

On OPTO Trigger 5, the opto-couplers do not directly connect to the output, but are buffered by MOSFET transistors. These transistors build an easy-to-use open collector driver with a 20 mA static current diode as pull-up. Note that the power must be delivered by the external power source.

Info

OPTO trigger 5 has been designed with a varistor which opens at an input voltage of 30 VDC to let the onboard surge protector get active to protect the board. At a total supply voltage of 36 VDC, the electronic chips will become defective.

Timing Characteristics#

Inputs#

Min Typical Max Unit
Propagation Delay 200 230 260 ns
Min. Puls Width 200 ns
Max. Frequency (50% Duty Cycle) 2.5 MHz

Outputs#

Min Typical Max Unit
Propagation Delay 40 60 80 ns
Min. Puls Width 200 ns
Max. Frequency (50% Duty Cycle) 2.5 MHz

Due to the use of a static current diode as pull-up of the output signal, there is a static rise time that leads to different low-high transition delays for different voltages and loads. The delay time is measured without load from/to 50 % of the signal level.

Use Cases#

Using Multiple Boards#

You can also combine multiple boards, i.e.,

  • use multiple OPTO Trigger 5 boards with one frame grabber board, or
  • use one OPTO Trigger 5 board with multiple frame grabber boards.

You connect the frame grabber(s) to the OPTO Trigger 5 board(s) by a specific 34-pin flat cable (see below). The signals of this cable use open collector drivers.

Using one OPTO Trigger 5 for several frame grabbers makes synchronizing the frame grabbers most easy. By sharing the trigger input lines of OPTO trigger 5, all frame grabbers in the PC are accurately synchronized. All frame grabbers connected to one OPTO trigger 5 must be seated in the same PC.

In most use cases, one OPTO Trigger 5 synchronizes all frame grabbers seated in one host PC. This is useful if the acquisition is controlled by an external generator.

Info

Do NOT connect frame grabbers residing in different host PCs.

Info

To connect the devices in the host PC (one or several Opto trigger 5 boards and one or several frame grabbers), use a custom-tailored 34-pin flat cable which provides all required connectors in the desired order. Contact Basler sales department for ordering information.

Info

Don't connect the following pins between two frame grabbers:

  • Pin 2
  • Pin 4
  • Pin 32
  • Pin 34

If you use the special 34-pin flat cable available from Basler, these lines are already disonnected directly on the cable.

Info

There are applications where no external source is available or desired. In these cases, synchronization of multiple frame grabbers is not possible via OPTO trigger 5. Instead, a master frame grabber needs to synchronize all its slave frame grabbers.

Info

microEnable IV AD4-CL, microEnable IV AD4-LVDS, and the microEnable IV VD4-CL with implemented I/O option "3.3V TTL (LVTTL) compatible (push/pull)" DO NOT allow the connection of two or more microEnable IV frame grabbers via the flat cable.

Connecting a Shaft Encoder (Example)#

Pins#

You connect the two differential signals (A and B) of the Shaft encoder to one of the trigger board ports as follows:

Connecting a Shaft Encoder

The Shaft Encoder sends differential signals, i.e., signal A+, signal A-, signal B+, and signal B-. Therefore, you have to use four pins (11 - 14) for receiving two signals (signal A and signal B).

Explanation#

If you are using a Shaft Encoder, you receive either one signal or two signals (signal A and signal B).

Using one signal, you are receiving pulses when the transportation belt is moving.

The combination of both signals indicates in addition if the transportation belt moves forward or backward. If you are receiving both signals (A and B), you can suppress and compensate backward movements.

One signal, indicating the movement of the transportation belt:

Two signals, indicating movement and direction of the transportation belt:

  1. The only Basler standard frame grabbers that can't be connected to OPTO Trigger 5 are the stand-alone devices of the LightBridge series. 

  2. Known issue: In some cases, LED O INV shines less brightly than the other LEDs when Opto Trigger 5 has been configured via software. This doesn't indicate any difference in function.
