Firmware for EDX-200A Ver.02.11 (08/25/2022)

EDX-200A firmware version update

Ver. 02.11 (08/25/2022)

Fixed the following bug.

  • Fixed the bug in which the monitor output (analog output) on the CVM-40A and DPM-42B series (DPM-42B, 42B-F, 42B-I, and 42B-I-F) sometimes stopped after balancing was performed.
    This bug occurs when the balance operation is performed with none of the balance targets present (none of the balance targets are present, meaning that "BAL OFF" or "BAL NONE" is selected for all measurement channels).
    *The same event also occurs in inner sensitivity register (in this case, the event occurs when there are none of the objects for the inner sensitivity register).
    *This bug does not occur in the CVM-41A and DPM-42A series.
  • Fixed a bug in which a communication error would occur in rare cases when balance operations were executed from a PC in synchronous operation using a LAN cable, and subsequently EDX operation would become unstable.
  • In reading TEDS information, some recommended mode values based on the reading results have been changed.
  • Fixed the bug in which monitor data could be transferred beyond the transmission buffer size in the GDD command.
    *This bug is not affected when DCS-100A is used.
