A: No. The "Update Firmware" button in Opcom software only works for legitimate 1.78 to 1.85 updates. For 1.99, you need a PIC programmer.
: Officially, original OPCOM firmware development branched differently. Most stable clone units rely on hardware optimized for version 1.59 or 1.64. opcom firmware 199 hex file work
What the 199 HEX claims to do
Modern software versions require genuine hardware interfaces with active licenses. If you connect a firmware 1.99 clone to modern, unmodified software, the software will detect the clone. It will then overwrite the microcontroller, disabling the device. How to Flash an OP-COM Hex File If you connect a firmware 1
: Newer versions of official OP-COM software include counterfeit detection. If you open a clone 1.99 interface with official software, the software may send an invalidating command string to wipe or lock the firmware.
