Loading FIR filters into DFM processors & amplifiers

17 September 2019: NetControl2 (2.4.6) appears to have problems loading FIR filters and we are currently working with DFM to resolve this.

This page describes how to load FIR filters from FIR Designer M, FIR Designer and FIR Creator EX into DFM processors.

In the Export tab, select the format “Text file (Column, decimal)” and press Save FIR. Rename the TXT file extension to FIT.

Contact DFM to receive a download link for the NetControl software and install.

  • Run NetControl.
  • In the GroupList panel, right-click on ROOT, select Add devices and select a device. In this example we have selected the DMOD2SX.
  • The Device panel appears. Click on any of the FIR tabs or buttons.
