These two links no longer work. Will someone please post current working links? Thanks.
You're welcome. It's getting a bit tiresome chasing the moving links.
I've done some code mods to the ERR Sound Converter to get properly working ditch lights. Although not in the documentation for the Sound Converter, there are three LED outputs on the six-pin connector, two of those LED's provide ditch light functionality. I recently wanted to use ditch lights in an upgrade, so I set about fixing the functionality so it would be suitable, there were a couple of issues with the "as delivered" code. Here is the latest version of my code.
The Sound Converter should be connected as documented as far as serial data and power, the ditch lights are connected using a 1.5mm 6-pin JST-ZH family connector. Below is a snippet of the schematic for the ERR Sound Converter board, LED#1 and LED #3 are the ditch light outputs, pins 1 & 5 are the positive side. No resistors required, each output drives one white LED.
One installation note. In certain environments, the Sound Converter will load the serial data enough to cause issues with other serial functions, specifically sounds and/or motor control in the case of the ERR Cruise Commander M. This is because the standard connection to the Sound Converter drives the serial data through an opto-isolator, and the serial data is required to supply the power for the opto-isolator. There is a work-around for this, if you move the serial data line from pin-1 of the 4-pin connector to pin-3, it drives an unbuffered input. This reduces the load and allows other serial data users to see the serial data. Since the serial data for TMCC is frame ground referenced, this shouldn't create any issues, and it's worked fine for me.
If you are not using the actual Sound Converter feature of the board to drive a conventional sound board, you can also remove the rather large and bulky LM317 regulators to make a more compact package. I do that, and then I stick the whole board in a piece of heatshrink to insulate it.
Obviously, not everyone is setup to compile and program the board, so if you want this functionality, you can contact me and we'll work out an update for your Sound Commander code.
Thank you Bigdodgetrain!! A video is so much easier to learn from than reading about it in a manual!!!
I concur, thanks for the video, very user friendly !
Gunrunnerjohn, you ever come up with the wiring diagrams for the RCDR V1?
Yes that was very helpful, although a little slower talking and a bit more effort to articulate your words would be nice for this old goat.
Gunrunnerjohn, I am talking about the RCDR that you have listed second to the last page on this forum and listed as Legacy RCDR and BEMC wiring and pinouts. On the last two pages it shows the RCDR V1 with wiring diagrams coming soon. Here is the link:
I'm not the guy that was posting those, I just repeated Bruk's document posting. He's the guy to ask about the pinouts.
The original Lionel TMCC system came with a list of commands that could be sent to the serial port on the command base from a computer. Is there a similar list for the Legacy system? I am trying to add some of the new command strips to JMRI so I can expand control capabilities of JMRI for Legacy equipped rolling stock. Cannot seem to find this info anywhere.
Yes There is but you have to become a LCS APP writer they will have you sign a NDA and then they will email you all the command protocol for Legacy the contact info i can PM you if you want i am a LCS app writer and got all the info
Yes Please. I am the keeper of the JMRI TMCC development and would like to keep JMRI up to date.
wow they changed it so now it is public nice
It's public, but it's an older version of the spec. I've had 1.22 for some time now, and the one that's linked from the LCS page is still 1.21.
yea i have 1.22 also but for his needs that should get him what he is looking for the 1.22 was for sensor track and some of the new lcs equipment sounds like he just wants to send legacy commands using JMRI
Thank you for putting these on our site. Will help answer a lot of questions like " A wire broke off and I don't know where it came from".
Here are some manuals for ERR products that have been discontinued.
Bruk's lastest Legacy documentation, this is a must-have for those working on newer Legacy equipment.
A great big thank you for Bruk for all his hard work on these!
I've been asked for this frequently, here's the latest versions of the JWA product manuals.
