  1. and ... What do you think may still ask if NI provide tools to circumvent the blockade? Will it succeed?😁🙄
  2. As in the topic, the problem of a large number of adapters : NI GPIB-USB-HS From software version 17.6 (NI 488.2) all Chinese adapters (mainly bought on ebay) are detected as not genuine. So far the solution is to use software version 17.0 (which is also not available on the NI website). But is this the only solution? According to me, there should be at least 2 more: 1 - finding a module (entry) in the software which, after detecting an incorrect number, throws this error. 2 - (or even better) find the entry in the adapter's flash memory where the serial number is and change it Has anyone tried to deal with the topic? So far, I have not been able to find such an entry neither in the software nor in the memory of the adapter, most likely this value is encrypted in some way. and ... ... programmed eeprom 24lc256 (from original unit) serial no. changed in NI MAX but software still sees it as not genuine? WTF? (on version NI MAX > 17.0 ... actual 21)
  3. Interface GPIB-USB-HS National Instruments The device is fully functional But software from version 17.6 detects them as non-genuine until version 17.0 - no such problem. (and I attach this version to the set on CD - it works from winXP to Win10) Bought a few years ago on ebay Inside, the electronics do not differ from the original. Price : 179 Euro more info please contact via priv (shipping cost in EU ~ 10 Euro) (pay via PayPal)
