Thank you for the reply.
I am a bit surprised by the response. Serial Communications are not random. Once the parameters are known, they should be very repeatable and reliable. I was hoping you would know all of the parameters for the serial communications, but apparently, you do not. Your suggestion to “think about whether I need to swap jumpers” and “be sure I have the right serial parameters” are not very helpful as I do not know the correct value of these parameters. There are many combinations of these parameters to be tested.
Specifically, I am looking for someone that already has a working connection, and is connecting from the NX-584 card directly to the Veralite via a DB-9 to USB Cable. With the same parameters you are using, I should also be able to establish a connection. If you have a working connection between your CADDX NX-8/NX-584 and your Veralite, can you please answer these questions:
Are you using a standard DB-9 to USB cable, or, is it a “null” DB-9 to USB cable? If you are using something else, such as a DB-9 to IP cable, please specify.
Using that cable, how have you set each of the 4 jumper points on the NX-584 card? The jumpers are J7, J8, J9, and J10. They can be set in either position “A” or position “B”. The default settings are:
J7=A
J8=B
J9=B
J10=A
How have you configured the memory Locations on the NX-584 card? There are 4 memory Locations that must be set. The default settings are:
Location 0=blank
Location 1=4 (9600 baud)
Location 2, Segment 1 = 2,7
Location 2, Segment 2 - 1,2
Location 3, Segment 1 = 2,4,5,6,7,8
Location 3, Segment 2 = 1,2,3,4,5
Location 3, Segment 3 = (none)
Location 3, Segment 4 = 4,7
“Eddie” has suggested the following settings:
Location 0=blank (binary)
Location 1=6 (38400 baud)
Location 2, Segment 1 = 2,5,6,7,8
Location 2, Segment 2 - 1,3,4
Location 3, Segment 1 = 2,4,5,6,7,8
Location 3, Segment 2 = 1,2,3,4,5
Location 3, Segment 3 = 1,2,3,5,7
Location 3, Segment 4 = 3,4,5,6,7,8
Are there any other settings on the NX-8 unit itself (not the NX-584 card); notifications, etc. that should be set???
What are the Serial communication settings you are using on the Veralite when you setup this device:
Baud?
Data Bits?
Parity?
Stop Bits?
Are there any other parameters or settings on the Veralite for this device?
Again, if we are all connecting our NX-584 to our Veralite, this should be a very consistent process if you know all of the parameters. Some of you have apparently figured out the correct combination of parameters. Please, please, please share them.
[quote=“futzle, post:2, topic:181301”]I would follow the same advice that previous users in this situation have been given on the forum:
- Think about whether you needed to swap the jumpers on the NX-584 board. In your case I think you do need to swap them.
- Be sure you have the right baud rate and other serial parameters.
- Plug the USB connector into a real computer and start up a terminal program and see what you get.
- Use a powered USB hub to overcome the poor USB power that Vera supplies to its ports.
- Enable verbose debugging in the plugin and catch a Luup log.
Follow that list from top to bottom. Notice how most of the problems are hardware-related and that you don’t get to work with the plugin till the last step. Historically hardware problems are more common (look for yourself on the forum), and unfortunately they are the ones I can help you with the least. The plugin reports most hardware faults the same, as a failure to receive any data from the NX-584. It isn’t in a position to know what the problem is until it can start seeing bytes from the serial port.[/quote]
