Z21 Loconet T-B

[redpiperbob]

Hi all

does anyone know when Roco are to release the loconet T-B interface. ( I have a Digitrax BDL168. And I does wont to loose it.)

 Thanks Bob

Hi Dutch master

Thanks for your reply what you have said does make sense to me But I dont want to play about with the Z21

Just in case I ruin it.

Hi Vincent

Thanks for the dia I am away this weekend  but will try it out next weekend.  I will let you know how I get on

 

Thanks

Hi Just wondered if anyone had news about the development or forthcoming release of this adaptor?

 

Thanks

Bob contacted me off-forum to ask for a diagram. Here's the most basic variant:

LN-t_to_LN-B.jpeg

 

This diagram assumes the Roco X-BUS connectors have working C&D wiring, something I haven't been able to establish beyond doubt on my Z21. I believe it is, but as I haven't used them as such I'm not sure. Mind, the Z21 has an internal common connection between the GND (or negatives) of both the X-BUS and the L-Net socket, so strictly speaking you won't need to include these. Both diodes are 1Amp Schottky types, more then sufficient for the power requirements of the L-Net bus. Both resistors are 390 Ohm and need to be ¹/₂ Watt type.

 

Although it's likely to work, this may damage your Z21 and/or other devices as it may not completely comply to the X-BUS and/or L-Net spec's. Using this circuit is entirely your responsibility (covering my @rse here! )

 

HTH!

 

PS: if it doesn't work, I have an idea of a solution, but that's much more complicated as it involves a number of chips. Not of the potato variant, mind

Hi,

 

Did you ever get around to testing this interface - or has anyone else?

 

I need something like this to make LN-B available from my Z21 to allow the use of a DTM30 for a mimic control panel.

 

Are there any other solutions out there that will make the the LN-T onnthe Z21 into the required LN-B?

 

Many thanks
