RS232 Portable Buffer, 4 MB

  • RS232 Portable Buffer

Storage and transfer of machine data


General information:

  • Non-volatile buffering of serial data:
    • Print and plot data
    • Telephone fee information
    • Machine data
    • etc...
  • Conversion of baud rate, data format and handshake protocol possible
  • Addition of RS422, RS485 or 20mA interface modules available on request
  • Integrated diagnostic and startup aid: Setting dump
  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3

Application example "Transport of serial machine data":

It’s not always possible to connect a computer and the machine to be loaded with data using a serial data cable. Likewise, data transfer via diskette, CD or USB memory stick is often impractical (due to incompatibility or because a device does not have the appropriate terminal) or undesired (due to virus transmission). In these cases the RS232 Portable Buffer can be used as a transport medium - almost like a "memory stick" with RS232 interface.
