This is a good opcom hardware that use an original MCU( PIC18F458). I saw fake MCU’s soldered in this hardware instead of real MCU’s. HQ clone it is a name of the interfaces that can works with a cracked software to make difference between them.
MCU( PIC18F458) are built-in high quality of opcom firmware 1.99 and opcom firmware 1.59
And both opcom firmware 1.99 and 1.59 is tested working fine with vaux com 120309a which is available free download:
