Can anyone point me at the pinouts for the KDJ11-E
pdp11/93 DB9 rs232
connectors for the extra 7 (simulated) DL11s?
Alas, documentation on the 11/93-94 seems to be very scarce on the ground.
(And, just for grins, the page in the 11/94 User Guide which has the section -
1.2.6 - which talks, however briefly, about that panel - pg. 1-4 - is missing
from all the online copies of that manual which I
checked.)
The only thing I can suggest is that if you actually have the cable, the
pinout on the board is given in the KDJ11-E User's Guide (EK-KDJ1E-UG-001,
available online), on pg. 88-91 (aka 2-13 to 2-16), and an ohm-meter and some
time will give you the pinout of one of the DB9's - presumably they are all
the same, from there.

Hmm. Interestingly enough I just searched through both the 11/93 and
11/94 manuals, which I referred to before, and neither actually seems to
have the pinouts for the serial ports. Oh well.
The console is on a DB25, with a very standard RS-232. I hope everyone
can manage to get that one right.
For the DE9 connectors, they actually also follow the RS-232 standard.
For a connector without the modem control, all pins are in the first 9
anyway, so no problem. If you want full modem control, there is one
signal - DCD I think, which is on pin 20 in the RS-232 spec. On the DEC
DE9, I think that one was moved to pin 8. But someone should check that
out, in case they actually want full modem control.

And I just read Glen Slick's response about the pinouts, where he listed
them fully. Apparently, DEC never did modem control on any of the ports,
so it's just 2,3,7 which are useful anyway.

I have that manual, I am not sure whether it is missing page 1-4. I will
check.
If I have that page, I will scan it and email it to Al.
Jjust a few months ago, I wanted to connect a VT510 to the console port.
All connectors are DE-9, and I *assume* that they all have the same pinout.
What worked for me is the "VAX console cable", in other words: that DE-9
connectors is NOT "PC alike"! You can find the VAX console cable pinout on
the web. You only need to wire RXD, TX and GND.

There you have all the pinouts of connectors and everything you could need.
Oh, and the 9-pin serial ports (all but the console) have 2,3 and Rx/Tx
and 7 i Gnd. Just like in the 25-pin connector. :-)
