ASR-33 / PDP-11 question

Ok, I need to call in the experts. I have had much success lately in getting my PDP-11/34 system hooked up to multiple peripherals, running RSTS/E V7. I have RL02, RK05, multiple VT52s, LA36, VT100 all working running timesharing, terminals all connected via EIA DZ11. I added a 20mA DZ11, which is recognized by RSTS, and it uses 8 more KB numbers, with 8 less "unrecognized devices". The EIA DZ11 uses KB3 through KB10. I have configured the lines that I'm using so that the terminal characteristics are set properly by $TTYSET to match the terminal types when the system starts. The 20mA DZ11 uses KB11 through KB18. I want to connect my ASR-33 to the second terminal connector on the distribution panel, therefore it should be KB12 to RSTS. My problem is that I am now attempting to connect my ASR-33, which works just fine is local mode. I am using phone wire, connecting wires from the DZ11 connectors 1,2,3, and 4 to connectors 3,4,6,and 7 respectively on the ASR33 terminal strip. My info tells me that: DZ11 1 = Receive + = ASR33 7 DZ11 2 = Receive - = ASR33 6 DZ11 3 = Transmit - = ASR33 3 DZ11 4 = Transmit + = ASR33 4 Something must be working right because if the 11/34 is not on and the ASR33 is turned on in "online" mode, it sits there and "clicks" repeatedly. However, it stops this clicking when the 11/34 is powered on. I checked the lines and there is a 20mA +/- current on the lines. The problem is that when I type on the ASR33, it does not echo, and when I use RSTS to send characters to the ASR 33, it does not respond. This ASR33 works perfectly in local mode. Anyone on the list have a clue what's wrong before I dig deeper? Is there something obvious that I've done wrong? The ASR33 is supposed to be working. I have configured the ASR33 on KB12 to 110 baud using $TTYSET, but no luck. Just to be sure, I set all 8 KBs, KB11-KB18 to use ASR33 terminal chracteristics. Help would be much appreciated. Ashley
