abeasst Posted April 25, 2020 Share Posted April 25, 2020 I have gotten the IT-230 communicating with the alarm panel, but I can't get the below adapter to convert the RS422 to RS232. I wired the below adapter in the below manner and it still says "Establishing Communication" in Composer. IT-230--------RS422 Adapter TX(+) ---------- T/R (+) TX(-) ---------- T/R (-) RD(+) --------- RXD (+) RD(-) ---------- RXD (-) Anyone used this adapter before and able to help me with the wiring? https://www.amazon.com/gp/product/B0196AO1IG/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1 Quote Link to comment Share on other sites More sharing options...

If the driver is still trying to communicate with the pannel that means there may be an issue in the wiring. What I can tell you is c4 use pins 2 , 3 and 5 to communicate Maybe this diagram will help you Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
