I got a DSC PC1832 with keypads mixed into a box of electronics I got. The DSC works fine standalone. I have just about given up getting the DLS5 software working. I have used HAI Dealer Access, ELK RP2 and Ademco Compass software successfully but the DLS5 has got me stumped. I've found all kinds of forums where other people have the same problem. The problem is I never can get the PC1832 recognized by the software. I've tried every combination of wires for the serial connection with no luck. Anyone have any success getting DLS5 working reliably?
