Option 11 will not listen to me

[FireFighter78]

Our antique Option 11 will not receive information on the serial connection.

Here is my story -

One day I disconnected the A connection to a Windows PC running Putty and when I reconnected it the Option 11 would not respond to anything entered on the PC. The PC was still receiving CDR output.

I switched to the B channel and everything worked fine.

I thought no big deal leave the B channel connected to the PC and connect the A channel to the CDR recorder.

A couple days later I need to change something on the Option 11 and could not.

I have changed cables, check the cables, changed MPS/SDI cards, changed CPU cards, restarted the PC, restarted the Option 11, kicked the PC, kicked the Option 11, grumbled, whined and complained.

What did I miss?

According to your post, it doesn't look like you missed anything. Is there anything else common that you haven't touched? Maybe a modem eliminator? Could it be the slot the SDI card is in? Maybe you could move the card and rebuild the ports in a new slot? Have you connected a laptop with Procomm or Hyperterminal directly to the ports for testing? Maybe you need to kick it harder?

We were thinking that it could be the back plane and swapping it with another. Will the Option 11 allow MPS/SDI card to be in a different slot? (that certainly would be easier than replacing the back plane)

I did forget to mention in the first post we did try connecting the Option 11 to another computer. To potentially confuse matters the original computer is connected to an Option 21 and they talk to each other just fine.

I did try kicking the Option 11 harder and broke my foot causing me to loose 4 days of work. (The preceding statement is completely fictional - well not completely I did kick the cursed beast but only to make me feel better)

DID you ask it nicely?

I don't know why but alot of people tend to think backplane automatically and I have never seen a bad one on an Option 11 that was not physically damaged by a tech.

Is the port you are having trouble with TTY 0? If so try replacing the octopus cable first.

Is the 11 giving any print outs to the PC at all, ie time prints, errors ect? As you said this is an old Option 11 do you have the keyboard locked in CAPS, some of the older systems need to be that way ...

 

[FireFighter78]

Yes I did ask it nicely, every morning when I come in to work the first thing I do is check on it and see how its night went.

I only thought that it might be the backplane after switching the Option 21 to another cabinet fixed a problem there - I was thinking that it might be contagious or something.

I did replace the cable - same problem.

It is giving me correct output and I did not see any error messages that pertain to this.

YES I DO HAVE THE CAPS LOCK ON. Is there away to make the font larger? Perhaps the beast is more hard of hearing so when I get done here I am going to YELL LOUDER AT IT.

Thanks

Has anyone verified that the TTY ports are enabled?

You can log into a maintenance phone and manually enable them if necessary.

 

[FireFighter78]

I am not sure if I have a maintenance phone, well I started to set it up one day and not sure I finished. If I do, I do not know how to use it.

You should also have a serial cable off of the CPU card. Dip switches on the CPU tell you the baud rate. It wil be a DB9 connecter just to the left of your 25pr cables connected to each slot.

If your CPU is an SSC card, this cable will have 3 ports and port 0 will be the one controlled by the dip switches. If older than the SSC, this cable is the same as a standard DB9 to DB25 cable. either way you will need a nul modem connecter inbetween connecter to PC.
