[CA11] Rd424HD shuts off

I have a new Rd424HD that operates fine unless the unit is asked to operate past 6 mi scale. Also, same symptom of shutting off when the faster speed is chosen in ranges below 6mi. The radar is using the 15m cable length, I’m concerned that it may be experiencing voltage drop.

Does that seem probable vs software?

Unit connected to an Axiom Pro 12 RVX, with latest software. —no network switch.
