Then you need to reconfigure the MCU. Maybe SGK has configured it for testing for a lower temperature...
This can wait, until the back plane pcb is ready ...
BR, Toni
Yes,agree!
Just a question for now,are temperature and dc fault indicated by different frequency flashes of the red led?

Yes:
Red / Standby LED:
- Overtemperature: blink_sl_speed=BLINK_5HZ
- DC protection: blink_sl_speed=BLINK_10HZ;
Blue / Power ON LED
- repowering delay: blink_pl_speed=BLINK_2HZ
- repowering delay forced wait: blink_pl_speed=BLINK_10HZ
- mute delay: blink_pl_speed=BLINK_5HZ

If it is FT232RL running with 5V VCCIO it should be possible to use it...
In principle every USB2Serial converter with TTL level is usable. Speed for older housekeeping mcu is 19200 baud and newer like yours is 115200.

There is a mistake in your most right picture:
TXD from your converter should go to RX pin on MCU board connector ...
MCU board pinout pin1 - pin4:
- +5V
- TX
- RX
- GND

Wrong speed? Can't see, because of status "disconnected".Thanks Toni.I receive this.
BR, Toni
dead hardware ... ?No,speed is ok, 115200 but something is wrong with my interface
The magic instant!
Housekeeping circuit spoke.
To see text you must hit H on keyboard.
To be able reading words is necessary to change fonts in WST English bolt.
A stupid short between TXD RXD on the interface board was the matter of troubles.

Hint: use putty.exe using usb serial port...The magic instant!

Because i have only on-off switch(led illuminated),configuration changed to switch=1
I dont know what i will use for fault indication.
May be i must look for a common anode duo led
Ideally will be a duo led illuminated switch.
SGK has sent me a mini pcb that requires a push button and two leds,but this requires a difficult to find cap for the button and an extra fine front panel drilling.
