AOR AR5001D, AR6000 Owner's manual

Hello! I've reviewed the Operating Manual Addendum for the AOR AR5001D and AR6000 receivers. This document outlines a change to the ACC2 socket format, from Mini-DIN to RJ45, and provides guidance on which antenna selector to use with the new format. I'm ready to answer your questions about the document or the receiver.
Why was the ACC2 socket format changed?

Which models are affected by the ACC2 socket change?

Which antenna selector model should not be used with the new socket format?

Which antenna selector model should I use with the new socket format?

AR5001D & AR6000 OPERATING MANUAL ADDENDUM:

April 18, 2022

ACC2 socket format change (It only matters if you intend to use the optional antenna selector)

Due to component discontinuation, starting with serial # 09353001 for AR5001D and # 09441001 for AR6000, the

ACC2 socket on the receiver back panel has been changed from Mini-DIN to the RJ45 format.

In clear, if you intend to use the optional antenna selector, do not use the AS5001 model, but AS5700.
