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.
