4). RS-485 Carrier Sense (Default: Enable) 

RS-485  Carrier Sense  technology is the data flow control under RS-485 
half duplex (one-way traffic) communicating. Due to the reduction of TX/RX 
packet  conflicting  on RS-485 one-way  traffic bus, it will enhance better 
system performance and RS-485 communication ability.  Please refer to 
chapter 6.1 for technology detail.
