K3 like control and k3s radio TERM displayed

[Ik4pkn]

Hi everyone, I have two k3s, one of which k3s ... k3 used as a control and k3s used as a radio (remote site)
I have them here on the work table connected in the same lan, but when I turn on the k3 the k3s turns off .. I turn off the k3 and the k3s turns on completely blocked with the display on and the word TERM.
if I turn off the k3s you hear the click of the relay the display stays on but without any illuminated segment, empty ..
if I turn the k3 back on, the k3s switches off ..
anyone have any idea of ​​this poltergeist?

I solved the problem!!!
it was caused by the KI03 remote module, which houses the rs232 serial and the ACC connector.
The module only seems to have passive components but I will try to fix it anyway. Fortunately I had a spare rev.b ..
thanks for reading ...

it was very easy to find the fault ... it will be more difficult to find the inductance from 100uH smd !!!
