Hello Hans Wilhelm,

For IOT2050 Advanced, after making RS485 configuration changes, a complete power cycle is essential - a normal reboot is not sufficient. You must:

1. Disconnect the power cable
2. Wait for a few seconds
3. Reconnect the power cable

Please have a look into the topic Adjust Peripherals on IOT2050 Advanced in our Application Example to find more information about the configuration.

I copied you the necessary steps:

unknown user

Use the following command to get into the setup:

iot2050setup

 Perform the following steps:

Peripherals -> Configure External COM Ports -> RS485 -> Select "Turn on terminate resistor" (spacebar) -> Confirm with "Ok"

 The setup- and hold-values must be adjusted as follows (0x0005): setupholdtime.png

Confirm with "Ok" -> Cornfim again with "Ok"

Important: After the changes to the IOT2050 Advanced, it is essential to perform a manual reboot: To do this, disconnect the power cable from the device for a few seconds and reconnect it. A conventional reboot is not sufficient for this!

 After making changes in iot2050setup, don't just reboot - perform a complete power cycle.

Hello Hans Wilhelm,

this is a strange behaviour as the iot2050setup should be pre-installed in your Example Image and be accessible using the command

iot2050setup

What Example Image are you using? Can you please use the following command to get some information to your Example Image version:

cat /etc/os-release

What Firmware version are you using? Can you please use the following command to get some information to your Firmware version:

fw_printenv fw_version

Please provide some details.

Hello Hans Wilhelm,

now I understand - you're using Industrial OS instead of our Example Image. Thats also the reason why you can't access the iot2050setup tool.

I would recommend you to use the Example Image and to have a look in our Serial Connection Example.

If you don't want to switch to the Example Image you should be able to call these switchserialmode-commands...

IOT2050 Basic:

switchserialmode ttyuart -D /dev/ttyS2 -m RS485

IOT2050 Advanced:

switchserialmode cp210x -D cp2102n24 -m RS485 -g 1

The only problem is that you need to call these commands with every reboot so you should add this command to an autostart-script.

Hello Hans Wilhelm!

You need to decide on your own if it makes sense to copy the Example Image to the internal memory (eMMC). The benefits would be:

• it's more an permanent solution compared to the SD card
• you can use the SD card slot for additional storage

It's important to have in mind that the eMMC will be completely erased with the installation.

To your second question: Our IOT2050 Advanced comes with an pre-installed version of IndOS (by default IndOS 3.2.3 at Advanced FS:09)

I guess you have removed this default-version with the re-install (Service Stick). You can find the Service Stick with IndOS 3.2.3 on our Download Page to go back to this version.
