Robertshaw DMS

[atlantatech]

I am having a difficult situation and need some help. Have a Robertshaw DMS control system, The old property manager left the owner's employ,apparently on poor terms. prior to leaving,he changed the password and some points and will not respond to any request for info. Does anyone know of a backdoor password for this system???
Thanks!

What do you mean by "system". Are you looking at a computer screen, an LCD on a controller, etc. If it's a computer what is the name of the program?

I don't know if you can still get literature on that stuff. Years ago I had to deal with an old DMS 35 system in the hotel I worked at for controlling our conference center rooms. We used what is now Invensis for programming problems and provided limited troubleshooting training. I believe a 4 digit password was like 1111 or 1234. Unfortunately I cannot recall.

You should still be able to get into the microsmart bus without the password. Do you have a Lim cable?

To connect directly to the DMS 35/3500. Try 170 or 123.

<<<What do you mean by "system". Are you looking at a computer screen, an LCD on a controller, etc. If it's a computer what is the name of the program? >>> I agree..

A "newer" DMS PC interface (rev 11.x) or DMS35 or 3500 with LCD display, should allow "170" where it says "enter password" .

A really old PC interface (rev 8.2) or DMS350 panel display may ask for a 3 charactor User name ; any 3 charactors will work for that. Then a password set with dip switches was "002" from the factory. Hopefully the DMS>PC cable & PC software is intact.

If there are graphics instead of just text, then that's another story. So a lot depends on the interface you're looking at, as to how you get into it. I love these old controllers. Too bad they were orphaned.

Default password = 170 abc
All access levels

[Archon]

Defaults are no good if someome changed it. Also, I have seen where the access level of 170 has been changed to view-only. There's a procedure for recovering the master password on a 350A or 35 only. A 3500 does not have a keypad/display so there isn't such a method.

DMS-3500?
What protocol is that?
Can I use a fieldserver to convert to BACNET?

[Archon]

No such luck.

There is a tridium driver, but only available from your local Invensys (now TAC) dealer.

It can't be cheaper trying to keep the old DMS running. Even with a DMS to bacnet driver (WebPRTL) and a Robertshaw expert, it was cheaper to just rip it out and start with new controls.
