Opticon releases new Firmware for the OPN-2500 - version FFN4076H

02-09-2025
by OPTICON shop

New firmware has been released for the Opticon OPN-2500 - version FFN4076H.



New in this new version:

  • Fixed communication issues when multiple OPN-2500's are connected at the same time, either directly to the PC or via a DOKKi multicradle.

Due to timing issues communication could become unstable or even stall when multiple OPN-2500's are attached to one PC, either being connected directly to multiple USB ports of the PC or be it via a DOKKi multicradle.

The solution is two-fold, the first part is the new OPN-2500 firmware whilst the second part is the newly released 'Csp2.dll'  (version 4.0.7.3) where the timings have been finetuned to the new OPN-2500's speed. The latest Csp2.dll is already included in the Companion Application installer.
For your Custom application the latest Csp2.dll can best be pulled from the 'Companion Application' installation directory as this App is being updated more frequently than the larger SDK. You can find the download links below.

The new versions are available for download here:
