The PCIe bus data throughput depends on the motherboard, the chip set, and the BIOS configuration of the host computer. It can differ from slot to slot. It can also depend on the number of installed PCIe boards, e.g., a PCIe x8 connector may support only x4 performance. For more information, check the manual of your mainboard.
For help with the hardware installation, refer to the Basler boost CXP-12 Quick Install Guide.
To operate the interface card with a Basler boost CXP-12 camera, install the Basler pylon Camera Software Suite (version 6.1 or higher) on the host computer.
When installing the pylon Camera Software Suite for Windows, make sure to select the CXP Camera Support feature. This will install all runtime software, drivers, and related software tools that are required for operating the interface card.
- PCIe interface on host computer: The host computer must have at least one PCIe 3.0 x8 slot available.
- Power supply on host computer: When using Power over CoaXPress (PoCXP), the host computer must provide one female 6-pin PCIe connector for power supply. You can find the matching power connector on the interface card.
|Temperature during operation||0–50 °C (32–122 °F)|
|Humidity during operation||5–90 %, relative, non-condensing|
|Storage temperature||-50–80 °C (-58–176 °F)|
|Storage humidity||5–95 %, relative, non-condensing|
Allow sufficient air circulation to keep the temperature during operation below 50 °C. Additional cooling devices aren't normally required, but should be provided, if necessary.
You can use pins 8, 9, 11, 12, 13, and 14 on the front GPIO connector to receive trigger input signals.
You can receive either up to 3 differential signals, or two differential signals and one single-ended signal.

- The CXP-12 Interface Card 2C has been designed with a varistor that opens at an input voltage of 30 VDC (on the input lines). This activates the onboard surge protector to protect the board. At a total supply voltage of 36 VDC the electronic chips would become defective.

Ports and LEDs#
The CXP-12 Interface Card 2C offers the following ports:
LEDs on the Slot Bracket#
There are two status LEDs located on the slot bracket of the interface card. They indicate the status of the two CXP connections:
- Green: Connection at CXP link ready for operation.
- Red: No connection at CXP link.
LEDs on the Board#
The following LEDs provide you with information:
|LED Name||LED Color||Meaning|
|TRG||Yellow||There is external voltage supplied on the 15-pin connector.|
|READY||Orange||The FPGA has been configured successfully and is ready for operation.|
|USR1 to USR6||Green||User-defined. The LEDs can be controlled via software. They are not related to camera ports and can be used for any purpose.|
|PG_EXT||Green||"Power Good External": Voltage on the PCIe power connector is stable. The PoCXP voltage (24 VDC) generated internally is also stable.|
|PG_INT||Green||"Power Good Internal": Voltage on the PCIe slot is stable. The voltage generated internally is also stable.|
|12EXT||Green||Green: The interface card's PCIe power connector is connected to a power supply via the host computer.|
|12PCI||Green or red||Green: The interface card gets power via PCIe slot (12 VDC IN). |
Red: The interface card doesn't get power via PCIe slot.
Interface Card Connectors#
The card is interfaced to external devices via the following connectors:
- Two Micro-BNC connectors (HD-BNC) to transmit image data, control signals, and configuration commands. The connectors can also be used to provide power to PoCXP-complaint cameras via Power over CoaXPress (PoCXP). Please refer to the manual to connect the Interface Card to the PC power supply.
- A 15-pin D-Sub Micro-D connector used to send and receive trigger signals.
Two status LEDs on the slot bracket indicate the status of the CXP connections.

|11||Yes||GPI 0+||GPI voltage IN / GPI GND|

All general purpose inputs (GPIs) of the 15-pin connector are electrically isolated. The incoming signals are transferred to the interface card via opto-coupler. This way, the interface card is securely protected against high incoming voltages. However, to operate the internal GPI circuits, you need to connect a voltage source and ground: On pin 10, you apply the voltage (GPI voltage IN) that serves as operating voltage for the internal operational amplifiers. On pin 15, you connect the according ground (GPI GND).
Pins 8 and 9 can be used in two ways: 1) together for receiving a differential signal, 2) only pin 8 for receiving a single-ended signal. In case 2), pin 9 is not connected.
The voltage applied must be the same voltage as the signal source voltage.
The CXP-12 Interface Card 2C trigger system needs to get supply voltage on the GPI Voltage IN pin (pin 10). If you want to connect devices that have no PWR pin, you need to provide the power supply to the GPI Voltage IN pin from an external source.
