Hey guys and gals,
I have tried and failed to get a successful connection between my uvax II and a pc rs-232
serial port. The H8751-B didn't seem to work, so I pulled it off and wired my own
MMJ-DB9 connector. I have tested the MMJ cable, and it works flawlessly.
For my connectors I have followed "The Cable" documentation at
http://www.mcmanis.com/chuck/computers/vaxen/panels.htm (chucks house of vax), under
"The MicroVAX II" section but it hasn't helped. I have tested the MMJ-DB9
connection from my uvax III consoles and from the microvax 3100 and it works fine, so I
think the PC side is working correctly.
The MMJ-DB9 on the pc side is
DB-9 Pin Color Purpose
1 Pin 4 & 6
2 Yellow Transmit
3 Black Receive
4 Pin 1 & 6
5 Red Signal GND
6 Pin 1 & 4
7 N/A
8 N/A
9 N/A
When I toned out the H8571-B connector and this is what it toned out to (using a straight
MMJ cable out of the connector:
H8571-B Pinout
DB-9 Pin Color Purpose
1 N/A
2 Black Transmit (Tx+)
3 Yellow Receive (Rx+)
4 White DSR
5 N/A
6 Blue DTR
7 Red Transmit Ground (Tx-)
8 Pin 8
9 Pin 9
Any idea what pinouts I should use for the H8671-B -> PC connector cable should be?
This situation is driving me nuts.

If you have double checked a couple different cable options already, have
you double checked that the bulkhead panel for the KA630 is working
correctly? Is it possible that the battery leaked and corroded the PCB
traces on the bulkhead panel?
I've used both a homemade KA630 DB9 - PC DB9 cable and also an H8571-B MMJ
cable without any issues. It shouldn't be difficult if the KA630 panel is
working correctly and cabled to the KA630 correctly.

The MVII
"bulkhead" uses a non-PeeCee DE9 RS232 pinout. So your MMJ-DE9
adapters can't work. Just solder a DE9-to-DE9 cable as described on
"chucks house of vax".

MMJ adapters work fine with the KA630/650/655 bulkhead panel DB9 connector
if you use the MMJ adapter that is specific for that purpose.
http://h71000.www7.hp.com/faq/vmsfaq_025.html
14.27 What connectors and wiring adapters are available?
H8575-B - Older MicroVAX (other than the MicroVAX 2000) DB9 EIA232 serial
port. Functionally similar to the H8571-B, though the H8575-B has better
ESD shielding. Note: Cannot be used on a PC, Alpha nor Integrity DB9 9-pin
connector.

Jochen,
I actually have the H8571-B. I traced it out with a meter and found 5 connections, so
there should be some combo that works with the DB9-MMJ going to RS-232 on the other end,
right?
I could see there being an issue with the MMJ-DB9 if there were more than 6 wires involved
that I would need the DE9, but since the B8571-B has MMJ coming out the other side, there
has to be a solution.
I would use the H8571-B on the vax bulkhead side, not the pc side. The pc side would have
the DB9-MMJ.

^^^^^^^
You mean the H8571-J on the PC side. The H8571-B would indeed be correct
on the VAX side. I suppose I need to take photos since the two adapters do
actually look quite different from each other...

OK. Then it should
work - in theory. (I googled H8751-B and didn't find
any substantial information like a pinout.) But obviously it doesn't
work in practice. So - at least for me - thats the point where I heat my
soldering iron and solder a cable where I _know_ that it has the
correct wiring. Getting out a meter and mesuring the actual wiring of
the MMJ setup is a good idea also.

So, after connecting the H8571-B to the VAX db9 bulkhead, and then fabbing an H8571-J (mmj
to db9) connector, and a straight (the only kind) MMJ cable, I have comms from the UVax II
to a pc com port. The only problem is, it appears that the system has a QxSS card, and
the only time I have any communication between the serial console and the system is when I
Halt it with the front panel button (or send a break signal from the PC). This gives me
the SRM console (>>> dead sergeant) prompt, and allows me to type "c"
to continue, but then immediately reverts back to the graphics console port for output,
which I have nothing to connect to.
The SRM console seems to be limited, it doesn't recognize "SET CONSOLE
SERIAL", it returns an "?18 INV DGT" most other commands return "?17
ILL CMD". if I try to tell it to boot from a disk (such as dua0) with boot/r5:1 dua0
I get "?15 CORRPTN" after a short while.
Any ideas on how to get this vax to boot with a serial console without having to pull the
QxSS boards out?

New subject: Which vax-vms license for a microvax II with VCB-02?
I've been wracking my brain over which license I need for VMS 5.2 on a microvax-II
with a VCB-02 graphics module installed?
I understand that I could just use the hobbyist licenses, but I bought the system with a
legitimate VMS license and want to keep it as close to the original configuration as
possible (I have other microvax systems with hobbyist 7.x).
Unfortunately there is no vmslicense/charge like you have with vms 5.3 and beyond.
I'm testing by connecting up a terminal to a serial port (not the console, thats a
different problem, won't work with VCB-02 installed unless you are in debug), and
trying to log in. Right now I'm getting license exceeded. I figured I would just
need a workstation license, but this doesn't seem to have worked.

The pinout for the cable at Chuck's House of VAX is correct. I just opened
up the connector shells on my own cable which I assembled more than 10
years ago and verified that it matches the information given there.
Your other option would be to use a H8571-B on the VAX side connected with
an MMJ cable to a H8571-J (or equiv.) on the PC side. While the two
adapters are both DE-9, the pinouts for each are very different.
I've used both solutions for my own systems, and I used to make and sell
H8571-J "work alike" adapter cables on eBay (DE-9F adapter with crimpped
pins to 6P6C jack, wired the same as a H8571-H, along with a 6P6C to MMJ
modular cable; I sold 100s of those things).
If you'd rather not butcher an MMJ cable, I'd suggest finding an H8571-J
adapter (useful with an MMJ cable for many other purposes as well). If
someone else can't supply you with a second hand H8571-J, I do still have
some NOS inventory (still in the original DEC bags) stored away (but not
/too/ difficult to get to) but I paid a good bit for them so I can't just
give those away.
