SeatTalk 1 to SeaTalk ng Converter LED Light will not Illuminate after Upgrading

[Angelsloft]

Completed an software update for the Sea Talk One to Sea Talk ng Converter to V.201 via a Classic E-80 MFD. After updating the LED light on the Sea Talk ng is not illuminated and will not communicate with attached instruments. Sea Talk ng converter operated properly prior to software update.

I tried numerous isolation tests but the LED light will not illuminate and the attached instruments (I-50 depth display and Smart Controller (S-100)) are now failing to operate. I tried to reinstall the software update (v.201) but the SeaTalkng Converter is not found during the upgrade process.

What could be the problem with the Sea Talk ng Converter and is a solution available?

Connected to the converter are:
- Blue: Blue/black cable to a 5 way Sea Talk Connector
- White; connected to a !-50
- Yellow: connected to the Smart Controller (S-100)
- White: Connected to an Classic E-80 MFD
- Blue: Terminated with termination plug

The I-50 display is connected to a P-70R display. The P70R powers on, communicates with the E-80 MFD and EV-100. Unclear why the P70R will power on but not the I-50 or Smart Controller.

Appreciate the assistance.

Thanks
Keith
