Posted By: Best Comm VMMI not communicating with DXP - 08/25/07 08:30 AM
After a lightning strike the DXP was down. A re-set got it working but it appears to have gone back to default program. I have a current backup but can't log in with VMMI. Receive message saying login has failed, make sure communication parameters are correct. I have tried using the customer's admin password as well as the default installer password. I have tried different baud rates. Any ideas? Thanks :bang:

just a thought, have you tried to log in using Procomm?

I'll bet the voicemail and the DXP are on seperate powers legs. The serial port is now bad on one or both peices of equipment.

Are you getting smdr, can you connect with hyperterm and is switch 8 on?

Unless the DXP is a very early revision the baud rate will not be effected by a default.
A good point by jwooten is switch 8, this will force the main serial port to 9600,N,8,1

I don't know why I thought I saw voicemail involved when I first read the post. :confused:
Was anything connected to the serial port when it got hit? If not the port should be OK.

Switch 8 is on. An on site programming computer was connected to serial port. I am in the process of loading VMMI software on my laptop to see if I can get in with it.
I don't have Procomm software. I tried hyper terminal but could not get a response.
Software is 13A

Thanks

loks like a bad maintenance port. thanks guys
I thought switch 8 just allowed new software to load. Switch 1 is the one that sets the default 2400 9600 baud rates on Com 1 and 2 (isn't it??)

Before you say the board is funky, disconnect all station and line cables reset the system then check. Also check 232-2. It's default is 300 7N2.
Justin, I don't remember sw1 doing that but then I don't remember alot of things. I will check hard copy back in the shop though!

SW1=96,N,8,1 comm main
SW7=init string for Comdial modem
SW8=new software load

Its been three years since I did this service call, as jwooten says, I don't remember a lot of things.

I'll relate my experience with a lightning hit system to the best of my recollection and it might give you some clues to what to look for.

I had a DXP with a revision around 6 or so and it was really really dead. I pulled out all the expansion boards and rebooted the system after plugging each one in one at a time - one of the analog boards was pulling the system down.

Now that I got the system running, I couldn't get it to connect to my laptop and I replaced teh service board.

NOW...I was able to connect to it, but login failed (I was able to get login two weeks earlier)

I replaced the CPU with Rev 11 or so, but my VMMI was too old to support it. I found a new version of VMMI and got into it.

Lightning is like that piece of hot dog your dog dropped behind your desk, it gets funky fast.
