I won't lie, I still have not gotten around to working with my PDP's because I've been extremely busy.
I have a CDQ-220A/E and I'm trying to access the configuration and formatting menu from the ODT. I can't find anything for the A/E so I'm using the documentation for the /M card and setting the address at 17772150. The MAP command says this address is already in use, probably by the RQDX but I can't find anyone saying it shouldn't conflict. The only instructions to get to the utility is to halt the system and enter the following:

Code: 
@17772152/005400 123456
@/001000 100
@5000G
SCSI UTILITY PROGRAM
   DISK          TAPE
BLAHBLAHBLAH
BLAHBLAHBLAH

however all I get is:
Code: 
@17772152/005500 123456
@/010247 100
@5000g
005002

No menu, nothing. I don't know what I am doing. I don't know if it's even normal for a backslash to return a six digit value on its own. Any tips?
 
So on this scrap of paper I have written:

17772152/ 123456
17772152/ 100
5000G

Try that. But first, move the RQDX3 to a different CSR!!!! I think the usual secondary MSCP controller location is 17760334.

When you have multiple MSCP controllers, you'll need to tell RT-11 about the secondary (and beyond) controllers. The easiest thing to do is to make a copy of DU.sys and call it something else, then set it with the CSR of the secondary controller.

What I did was to remove the RQDX3 completely from the system with the CQD220. I put floppy drives on the SCSI bus with Teac FC-1 adapters.

If you have a standard DEC 10-pin header to serial adapter cable you can also plug that into the CMD CQD-220A/E and talk to the onboard configuration utility at 9600,N,8,1

I have a PDF of the CQD-220A manual.

I can't. Whenever I do a backslash it gives me six digits representing something I do not understand. I can't just type
Code: 
17772152/ 123456
I am forced to do
Code: 
17772152/005500 123456

Regardless, I try what you say and...
Code: 
@17772152/100023 123456
@17772152/000000 100
@5000g
005002
...followed by the RX50 spinning.

My RQDX1 manual does not give jumper settings for alternate addresses other than 17772150. Can I put the CMD card on 17760334 instead?

I have the bulkhead cabling but I'll try that another time. I'm already fighting the front door. I don't want to start fighting with the back too.

Edited: Okay, so it works with the RQDX1 removed but I need it so I can use my RX50. Pardon me for the night guys, I need a drink.

As soon as you enter the '/' then ODT reads and prints the current contents of that location before you optionally enter a new value to store at that location. That is expected behavior.

Of course you can set the CQD-220A DISK CSR to 17760334:

(Note that CQD-220A/E == CQD-220A/M/T Either MSCP or TMSCP, not both at the same time)

Edit: Grrr, it tiny sized that table picture.
 
Okay, so I'm now down to this:

I can pull up the utility when I'm set to either 17772150 or 17760334 but the RQDX1 can't be installed. When the RQDX1 is installed (and set to 17772150) and the CMD card is set to 17760334 I get the following:
Code: 
@17760336/005400 123456
@/001000 100
@5000g
005002
Followed by the RX50 spinning. I don't know what it means then it returns 005002.
 
Shoot, I saw that pdf and ignored it because it was the same as another one I had. So I read over that one and confirmed that the card was properly setup so I decided to look over the RQDX1 manual again. I had completely forgotten that it MUST be installed in the last unoccupied slot. Switching the CMD and RQDX boards around cleared everything up.
