E1701A Modular Analogue Scanner Controller

Beside different other, common scanner cards BeamConstruct also supports the only modular scanner controller card worldwide*: the E1701A analog scanner card. This is a low-cost scanner card with the smallest ground-size out there* and it is the only one which can be extended by additional boards* providing different signals and outputs. So it is not necessary to buy one fully featured card and to pay for functions that are not needed. Via its extension boards only these functions and I/Os can be added, that are really required.

These extension boards are plugged onto baseboard. Several of them can be combined freely according to required functionality.

Please note: E1701A is in state "discontinued" and therefore not recommended to be used for new designs any more but only for maintenance and replenishment of stocks! Please use E1701D or E1803D together with HALdrive analogue converter instead.

E1701A is an analogue scanner card which can be extended
by options described by below and provides following features:

  • 16 bit analogue interface to scanhead with X and Y channel, ±5V and ±10V output
  • 3x 12 bit additional analogue outputs, 0..5V output
  • ILDA-capable interface
  • USB 2.0 and 100 Mbit Ethernet connection
  • Online XY grid correction with support for several correction table file formats (like BeamConstruct HD .bco correction files, SCAPS™ .ucf, Scanlab™ .ctb and .ct5, Raylase™ .gcd, GSI/CTI™ .xml, Sunny™ .txt)
  • Switching between up to 16 grid correction tables during marking process
  • 10 microseconds vector cycle time and resolution (microstep period)
  • Command execution time down to 0,5 microseconds
  • Realtime processing of laser and scanner signals
  • 26 bit internal resolution (for better quality also with 16 bit hardware output)
  • Can control nearly every laser type (this may require extension boards as described
  • 512 MByte DDR3 RAM
  • 1 GHz CPU clock
  • Support for Micro-SD and Micro-SDHC cards with up to 32 GByte disk space for stand-alone operations
  • Internal command and vector data list with more than 17 million entries
  • Continuous list concept, no need to swap between buffers
  • BeamConstruct PRO license included
  • Open source compatibility library that emulates existing programming interface for
    fast and easy usage with existing software (contains e.g. Scanlab™ RTC4™, SCAPS™ USC™/SCI and other compatible interfaces)
  • Very small size of about 87 mm x 55 mm
  • Shipped with easy to use connection kit
  • Hardware/firmware is quality made in EU/Germany

LP8 Extension Board requires E1701A baseboard as described above
and provides additional signals for controlling lasers and external
equipment. It offers following features and functions:

  • LP8 8 bit CMOS level parallel digital output e.g. for controlling laser power
  • LP8 latch CMOS level digital output for usage with IPG™ and compatible laser types
  • Main Oscillator CMOS level digital output for usage with IPG™ and compatible laser
  • 8 bit 0..5V analogue output e.g. for controlling laser power
  • Two laser CMOS level digital outputs for usage with YAG, CO2, IPG™ and compatible
    laser types (outputs can provide PWM frequency, Q-Switch, FPK-pulse, continuously running frequency, stand-by frequency), running with frequencies up to 20 MHz
  • Hardware is quality made in EU

Digi I/O Extension Board requires a baseboard as described above
and provides additional I/Os for controlling external equipment. It offers
following features and functions:

  • 8 digital inputs and 8 digital outputs can be switched to opto-insulated mode with
    external power supply of up to 24 V
  • 2 inputs can be used for 90 degree phase-shifted encoder signal for marking on-the-fly applications
  • Inputs can be used to select one of up to 256 stand-alone marking jobs stored on microSD card of baseboard
  • Hardware is quality made in EU

The optional E1701base Mounting Kit allows faster and easier mechanical installation of all types of E1701 controller boards:

  • Comes with DIN rail clamps which can be installed in 2 different positions combined with 2 different orientations resulting in 4 different mounting variants
  • E1701 can be mounted on top of E1701base with distance bolts or hex-stands using premanufactured mounting holes
  • Can be used also without DIN rail clamps for custom mounting in machines and as top-cover for E1701

* As per 06/2015 we do not know of any other scanner controller card
that is fully modular and comes with a smaller size for such a low price.
