All:

I have the need to connect multiple (3 to be exact) DZ-2001L's to a TMCC Command Base, shown below.

DZ2001A_l

The problem is the female stand-offs on the right (either side of the DB9 connector).  In the past, I have removed them and the housing and just pushed it onto the Command Base.  This time, I'm looking for a more secure way to attach them to the Command Base and to each other.

I've already tried reversing the stand-off.  It didn't work.  Can anyone suggest a solution or identify the type of screw or nut I might need?

Thanks,

George

Why do you need 3 DZ2001L's?  Do you have a lot of switches?  If so how many do you recommend per each DZ2001L?

It's not a matter of the number of switches.  It's the length of the data wire that can be an issue.  75 feet is the limit of that data wire.  My layout is 47'x11'.  I decided that the practical way to access all of my switches (37) was to divide the layout into thirds.

Remove one set of threaded inserts and then just use a twist-tie to hold the two connectors together.  For the command base, just use a short jumper cable, it's better NOT to have something long sticking out and potentially pulling the DB9 off the PCB in the command base anyway.

Curious. Will the base have enough signal strength to power 3? 

It should.  Besides, I am using a 15VAC tap to power all the TMCC components.

To answer GRJ’s concerns, I plan to support the 3 DZ2001Ls and DB9 cable connector with a small shelf.

Is this a Legacy base? 

No.  It's a TMCC Command Base.  The "L" version of the DZ-2001 will work with either TMCC or Legacy.  I think it has improved the way the cables are fastened to the board.
