Hello cerberus78, to round off the topic, please note the following: OpenLoadDetection is only active when the monitored output is low. If voltage is present, monitoring is deactivated. In addition, it is not possible to differentiate precisely between overtemperature, overload and openLoad See here...

Hello Cade, take a look here:

Hi Rumpelstilzchen, wenn du ein RevPi DIO Modul benutzt, dann sind dort ja die betreffenden MAX31913 verbaut. Das kann man in den Schaltplänen sehen, die sich hier befinden: https://revolutionpi.com/en/tutorials/downloads#schaltplaene Aber ich wüsste jetzt nicht, wie du diese per GPIOs ansteuern kan...

Hello Latassan, thank you for your positive reply and your explanations. That helps us to understand this better, great.

Hey Victor, I have created a test setup and hope it shows how easy you can transfer serial data: 1. Start miniterm python3 -m serial.tools.miniterm /dev/ttyUSB0 2. Set local echo on [STRG] + T, [STRG] + E 3. Monitor Pin 2 of D-SUB-9 plug - Pin 5 is GND USB RS232 Sniff RX Pin.JPEG 4. Type something i...

Okay but the PWR LED thing here made me think, I hadn't considered this detail yesterday. Hm. So if the PWR LED turns red and then green again, this is a sign that the communication between the modules is faulty. The I/O modules then go into the safe state and switch the outputs to logic 0. Can you ...

Hello, the RevPi Connect 4 can be operated in both the 2.4 GHz and 5 GHz frequency bands with the corresponding antennas. Here is the link to the data sheet:

No, unfortunately. You need to have a load to detect an open load and thus some electricity flowing through a cable.

Hello wmatte and welcome to the Revolution Pi community! So since the Bullseye OS, the "NetworkManager" service has been active here and controls the network. So the root cause may be that the IP connection was switched to "fallback". This occurs, i.e. if the DHCP server does not...

Hi, you can use a RevPi DIO Module and a RevPi Connect 4 Module. Here is what I would recommend you to have WLAN and much eMMC and RAM to experiment: chrome_5mqOQPNYd3.png However, if you want the cheapest basic module, you can, of course, use a different one as an alternative: chrome_8tCEOzCa9I.png
