[LW11] E80 not displaying GPS Status and not changing UTC time

Hello,

GPS antena Raystar 150 recently installed replacing a Raystar 125. New RS 150 installation includes a kit conversor SeaTalk to SeaTalk NG. New GPS cabling connected to existing SeaTalk network including 2x E80 MFD displays.

Everythink OK except for 2 issues:
a. The GPS Status page in the menu will not display GPS satellite status information, only HDOP.
b. The time displayed at Local Time window is always UTC even when I change summer or winter time hours at "Date & Time" page in the general adjustments menu.

Please advise what to do to solve a. and b.

Thank you, Alberto
