Stopping broadcast transmit on MPPT 100 15


I asked this question about a week ago, and I received no response. I will try again, rewording it.

I am trying to interface the MPPT charger with a stand alone LCD screen, and I want the screen to control the flow of communications back and forth. In order to do this, I need to turn off the broadcast on the TX pin from the charger. The firmware of this device is 1.16.

The VE protocol manual says that I should be able to permanently disable the broadcast function. I have been able to do this, but only temporarily. It seems that any activity on the serial port causes the broadcasting to restart.

Can anyone explain how I can permanently disable the serial broadcast on the TX pin?
