APMB2 - AEWA Print Manager Board


APMB2 is the second generation of Print Manager Boards from AEWA. It is the core hardware of the AEWA Printing System and can drive up to 8 printhead boards. It connects to the printhead boards via optical fiber cables which makes the data transfer immune to electromagnetic interference.


  • Different host interfaces:
  • APMB2-GBE: APMB2 with 1-Gigabit Ethernet and 2Gb RAM.
  • APMB2-USB: APMB2 with USB 3.0 and 4Gb or 8Gb RAM.
  • High speed Operation:
  • 1-Gigabit Ethernet: 110 MBytes/sec.
  • USB 3.0: 400 MBytes/sec.
  • Optical interface to printheads: 600 MBits/sec.
  • Encoder: 80 MBits/sec.
  • RS422 Interface: 10 MBits/sec.
  • Can drive up to 8 printhead boards.
  • Up to 500 meter distance from printhead boads through optical fiber cables.
  • Easy daisy chaning. Up to 16 APMB2 boards van be connected together to drive more than 8 printhead boards.
  • Supports rotary spiral, rotary step, flatbed and single pass band printing modes.
  • High speed encoder signal multiplication and division logic which enables any printing resolution.
  • Software programmable internal virtual encoder and print start signal.
  • Full featured printhead control (drive voltage, temperature, waveform, grayscale, etc.).
  • Firmware update over host interface.
