I have XTEND-PKG-R and I want to connect it to USB TTL
My connection is like this
PKG female RS‐232 (DB‐9)
TTL pin out
pin2 (Rx) ---- To --- > TTL (Tx)
pin3 (Tx) ---- To --- > TTL (Rx)
pin5 (GND) --- To --- > TTL (GND)
power connector --- To --- > Power Adapter 12v.
DIP Switch settings is (1,5) ON and others OFF .
but I couldn't connect to X-CUT software ,
Where is the problem ??
