Reporting back to the group and again thank you for all your assistance.
I received the old RS 20-047 cable and had a chance to try the firmware upgrade. All went well! Moved from firmware 1.02 to 1.10 (last firmware). The old RS cable worked without a hitch. The radio is working as it should. Thanks again for the help on this. For whatever reason, the first cable I bought would update frequencies but not update firmware. The old RS cable does both.
