USB to Serial

Not sure what the issue is but a device is no longer being created when I plug in a USB to Serial. I have access to it in the Mios Developers section so I know it’s recognized but the device does not show up. I can create a device for it manually but I need to know what parent device and service files to use. Any ideas?

Thanks,

Barry you may need to give folks the Vera version, Vera HW and some info on where you’re expecting it to show up.

For example, early UI4 releases (like 1.1.1008) were accidentally showing these as devices in the dash, when they were supposed to be hidden (like in UI2) everywhere except the serial port assignment UI

Well that explains it. It was showing in 1008 and is now not showing in 1047. I have to say that having it show up was nice so you knew it reconized it without having to go into anything.

It gets a bit too messy with many ports connected. It upset me to start with as I thought that it had gotten broken with an update, but now I don’t care about it so long as they work.

That brings me to my next question, I can’t seem to find the two TestSerial XML files. I see them mentioned a few times but they are not easy to find so far.

Thanks.

… so what are you really trying to do? :smiley:

It may be easier to walk you through that process instead, potentially by pointing you a live/working code samples (the online Developer docs our out of whack)

I am having issues getting the Vizia RF Emulator working so I am trying to create a simple device or lua code that will send ASCII strings based on lock events.

Ok. I’m not sure what a Vizia RF Emulator is, but I’m going to assume you mean Leviton VRCOP “Plugin Serial Interface Module with RS-232”

You can use the code from any of the following to give you a starter, depending upon the formatting required by the Device you’re trying to control:

http://code.mios.com/trac/mios_panasonic-tv - STX-ETX Encoding
http://code.mios.com/trac/mios_monoprice-hdmi-switch - RAW Encoding
http://code.mios.com/trac/mios_onkyo-media-control - Pseudo CR/LF with Checksums

And the Weather Plugin has some of the “stubs” needed to generate Scene “Events”:
Weather Plugin

There are a number of more advanced plugins in code.mios.com as well, depending upon the specific effect you’re trying to get going, but start small (with some of the above bits) and get it basically crawling first, then look to expand and/or add functionality.

PS: If you’re going to write a Plugin, you might want to move this thread to the Luup Forum to give it better visibility.

There is a Vizia RF Emulator Plug-in (beta) available on the Mios Marketplace. It emulates a Vizia RF+ VRC0P to a TelNet port or to a serial port (if installed).

I was hoping to find the TestSerial files because they would be a basic layout without having to wade through what someone else did.

Thanks for the help.
