RS232 extension - MGharat - June-12th-2019

Hi,

I am trying with RS232 extension module , but the container image is not getting deployed..

How we can know, if the RS232 connector is properly detected during boot by netPI? NO LED glows on extension module...


RE: RS232 extension - patrick - June-12th-2019

Hi,

please check your netPI software version if you use V1.1.5.0 or earlier versions. Please use V1.1.6.0, this version has a prolonged timeout value in case downloading containers from web takes too long sometimes.

Best Regards
Patrick

RE: RS232 extension - patrick - June-13th-2019

Hi Madhumati,

the leds on RS232 module are custom NPIX leds. You can switch on/off the NPIX led's with our "npix leds" Node-RED node.
This node is included in the "hilschernetpi/netpi-nodered-npix-leds" image.

Today we will release the "hilschernetpi/netpi-nodered" image. This includes all of our Node-RED nodes like "npix leds" and "serial rs232". The Modbus node will also be included.
I will keep you up to date if we have released this image.


UPDATE (2019-06-13):
The "hilschernetpi/netpi-nodered" image is now released.
