Pista Posted December 20, 2017 Report Share Posted December 20, 2017 Hello. I connected the Unistream HMI Panel USP-104-B10 with Uni-com module UAC-02RS2. (2xRS232) However, the power LED on UAC-02RS2 does not light up or blink. It's a hardware bug, or I'm doing something wrong. I use the software Unilogic version 1.21.51 . TX RX communication works well on this module. Does anyone know, how to help me? Quote Link to comment Share on other sites More sharing options...
