Compare Where to buy


The Coaxlink Quad CXP-12 JPEG enables the compact implementation of a multi-channel ultra-high-resolution image acquisition and recording system. The embedded pixel processing drastically reduces the CPU workload to monitor and compress image streams.

  • Power over CoaXPress : Feed your camera up to 17 W per channel under 24 VDC with automatic device detection, measurement and overload protection.
  • Total and per-channel voltage and current measurement is possible, allowing validation and performance deviation monitoring.

General purpose I/O lines
General purpose I/O lines

  • Compatible with a wide range of sensors and motion encoders.
  • High-speed differential inputs: Quadrature motion encoder support up to 5 MHz.
  • Isolated current-sense inputs: 5V, 12V, 24V signaling voltages accepted, up to 50 kHz, individual galvanic isolation up to 250VDC and 170VAC RMS.
  • Isolated contact outputs.
  • High-speed 5V-compliant TTL inputs/ LVTTL outputs.

Area-scan triggering capabilities

  • A trigger is used to start the acquisition when the part is in position. Hardware triggers come from the Coaxlink's I/O lines. Software triggers come from the application.
  • An optional trigger delay is available to postpone the acquisition for a programmable time.
  • A trigger decimation function allows to skip some of the triggers.
  • Camera exposure control allows the application to control the exposure time of the camera.
  • When the acquisition starts, at the appropriate timing, the Coaxlink board generates a signal to control an illumination device connected to one of its output lines.


  • The 4-camera firmware variant of the Coaxlink Quad CXP-12 JPEG implements four independent image acquisition channels with, for each of them, a Bayer CFA decoder and a baseline JPEG encoder that can process up to 250 Megapixels/s, for a total of 1 billion color pixels per second.
  • Each channel delivers two concurrent streams: a "JPEG" encoded stream for recording and a "Preview" stream for monitoring.
  • The JPEG stream delivers, with a typical latency of only 20 lines, 4:2:2 full-resolution JFIF-compliant encoded images compatible with standard JPEG decoders. The JPEG encoding quality is configurable from 1 to 100.
  • The Preview stream provides 8-bit Bayer full-resolution, 24-bit RGB full-resolution or 24-bit RGB low-resolution images.

I/O Toolbox tools The I/O Toolbox is a configurable interconnection of tools that generates events (usually triggers):

    • A quadrature edge detector delivering events on selected transitions of selected pairs of input lines.
    • An optional backward motion compensator for clean line-scan image acquisition when the motion is unstable.
    • A 32-bit up/down counter for delivering a position value.
  • Device Link Trigger tool (DLT): delivers an event on reception of a valid high-speed CoaXPress 2.0 connection trigger packet message from the remote device.
  • User Actions Scheduler tool (UAS): to delegate the execution of 'User Actions' at a scheduled time or encoder position. Possible user actions include setting low/high/toggle any bit of the User Output Register or generation of any User Events.
  • Delay tool (DEL): to delay up to 16 events from one or two I/O toolbox event sources, by a programmable time or number of motion encoder ticks (any QDC events).
  • Divider tool (DIV): to generate an event every nth input events from any I/O toolbox event source.
  • Multiplier/divider tool (MDV): to generate m events every d input events from any I/O toolbox event source.
  • The 'Input Tools' (LIN, QDC, DLT and UAS) can be further processed by the 'Event Tools' (DEL, DIV and MDV) to generate any of the following "trigger" events:
