  Introduction:

  PCL-846/847 series cards provide four independent RS-422/485
  serial ports on a card. Each port has a 16C550 UART with an on-chip
  16-byte FIFO buffer for reliable, high-speed serial I/O. The UART
  buffers data into 16-byte packets before putting it on the bus. This
  drastically reduces the CPU load and avoids data loss when the
  system is busy and cannot process the interrupt quickly. The UART
  is especially useful for high speed serial I/O under Windows.
  PCL-846 cards differ from PCL-847 cards in that they utilize
  on-board optical isolators to protect your PC and equipment against
  damage from ground loops, increasing system reliability in harsh
  environments. To further increase reliability, PCL-846B/847B cards
  include surge protection technology, protecting your system from
  abrupt high voltage surges (up to 3000 V) such as those caused by
  lightning during thunderstorms.

  An RS-485 Network with Automatic Data Flow Control
  Using RS-232 Software
  The RS-485 mode automatically senses the direction of incoming
  data and switches its transmission direction accordingly. This feature
  makes your network look and act just like an RS-232 network.
  Application software written for half duplex RS-232 can be used
  without modification. Moreover, you can simply and quickly build an
  RS-485 network with just two wires.

  PCL-839 – HIGH SPEED STEP MOTOR CONTROL.

  576,00 € Excl. VAT

  Introduction

  PCL-839 is a high-speed three-axis stepping motor control card that
  simplifies stepping motor control, giving you added performance from
  your stepping motors.

  Three-axis control
  The PCL-839 has three single-chip pulse generators on-board, which
  enables the simultaneous and independent control of three axis. The
  PCL-839 provides digital pulse and directional control (+ and -) for each
  stepping motor axis.

  User-friendly interface
  The PCL-839 has been designed to act as a user-friendly solution for
  your stepping motor control applications. Programming the PCL-839 is
  very easy. ‘C’ Libraries are provided and they contain all the command
  functions needed for total control of your stepping motors.

  Stand-alone interpreter
  A stand-alone, non-resident command interpreter, PROGg39.EXE, can
  also be used to control your stepping motors without any programming.
  Digital I/O
  The PCL-839 features 16 digital inputs and 16 digital outputs for general
  I/O use (on/off control etc.).
  Isolation protection
  The PCL-839’s PULSE and DIRECTION outputs and five limits input
  switches are isolated from the PC side.

  Features of PCL-839 :

  · Three on-board pulse generators that enables simultaneous independent
  control of three stepping motors
  · Two operating modes – two-pulse (+ and – direction pulse) or one-pulse
  (pulse-direction) mode
  · Programmable step rate from 1 to 16k pps (pulses per second).
  · Programmable initial speed, final speed and time duration. Automatic
  trapezoidal acceleration/deceleration Tamping is performed
  · 16 I/O TTL compatible channels
  · All inputs/outputs are optically isolated, providing 500VDC isolation
  protection
  · ‘C’ libraries containing device drivers provided
  · Command Interpreter provided that eases learning the PCL-839 command
  set

   

  Applications

  · Precise X-Y-Z position control
  · Precise rotation control
  · Robotics and assembly equipment
  · Other stepping-motor applications

   

  General
  · Power consumption: 300mA, +5VDC
  · Connector: 37-pin D-type connector
  · Board dimensions: 183.5 mm x 99.06 mm
  · Operatingtemperature:0 to70°C

  Introduction :
  The PCL-849 series cards provide four individually configurable
  RS-232 serial communication ports. The PCL-849A/849B/849L has a
  16C554 UART which makes serial I/O more reliable. The higher
  performance PCL-849+ has a 16C654 UART. By buffering data into
  64-byte packets before putting it on the bus, UARTs drastically reduce
  the CPU load. This makes the PCL-849+ especially suitable for high
  speed serial I/O applications under multitasking environments.
  The PCL-849 series cards support two operating modes, standard
  mode and enhanced mode. In enhanced mode, the address for all four
  ports can be set automatically. The PCL-849 series cards also support
  either shared IRQ or independent IRQ functions. When an on-board
  interrupt occurs, the interrupt status register (vector address) indicates
  which port generated it. The shared interrupt can be set to most common
  (extended) AT interrupts. This simplifies programming, speeds up
  interrupt processing and frees up interrupts for other devices.
