Here’s my situation:
I bought the ‘Assembled RS232 Serial Adaptor’, not from you guys directly, but let’s have it ‘from the horses mouth’ then, which I received a couple of days ago and which is behaving ‘kinda strange’. I’m hooking it up to my serial-out on a MAC G5. Power supply from the PC itself: At first I tried 3.3V… yeah, grounded of course… with no success at all when ‘looping’ the TX and RX outlets to test the connection via Terminal. They are not communicating.
After several attempts of disassembling and reassembling my setup [I lost count how often] I figured maybe the old ‘more helps more’ strategy will give me the desired result… so I’m hooking it up to 5.0V… grounded of course… and ‘bang’ success… TX and RX outlets are communicating when looped. Hooray!
But only once! Because after I disassemble my connections again to build my desired setup, I cannot recreate the TX - RX communication whatever I try.
Any advice or hints would be highly appreciated. Thanx
