My 485 comm port vanished
-
I have a Mango ES on which the RS485 port has disappeared. I've tried refreshing and restarting etc. Any advice? This mango seems to be acting odd because I had to delete the /mango/work directory before I could view data sources.

Hi psysak,
When you say refreshing, do you mean the browser page? Or, do you mean the little green refresh arrow next to the serial port drop down. I would have expected restarting Mango to have resolved that, were that the issue, though. I would bet there is no /dev/rs-485-1 device file, which points at a hardware issue that we'd probably be willing to RMA, but we'd rather conduct that in email.

I meant refresh with the little green refresh button yes.
Hmm interesting. OK, I'll aim to swap this unit out. Is there a way to do like a factory wipe of the device, kind of re-image the ES? I'd like to try that and see what happens from there. It's really odd because it was literally working one minute and then all of a sudden 485 port is gone.

rs485-1 file exists, links to ttyUSB0

Did you modify your env.properties file? There are settings for location and regex to identify your serial ports. Maybe you overwrote the MangoES's default,
serial.port.linux.regex=((ttymUSB)[0-9]{1,3}|rs(485)-[0-9]) serial.port.linux.path=/dev/ -
I didn't do anything like that consciously no, but perhaps I sleep programmed something :)
I'll have a look to see if something is amiss

Hmm... there seems to be something really not right with this unit. The RS485 port seems to be working ok right now but the unit keeps hanging up, it's done it 3 times on me now. Last time was during a config import, it just showed import in progress and then I can't ping it anymore. The previous time I was trying to enable one of the data sources.

Hanging up meaning Mango isn't running? Is there any indication of the cause in the logs?
