9. ke care of the RS 485 data flow control problem ADDC is a hardware data flow solution that automatically senses and controls data direction making the handshaking signal method unnecessary Isolation Moxa s electrical isolation technology uses two photo couplers to create a gap in each electrical signal One photo coupler transforms the electrical signal into a light signal which is transmitted across a small gap and then the other photo coupler transforms the light signal back into an electrical signal In this way the two electrical circuits are completely isolated from each other limiting the damage that could otherwise be caused by ground loops in the electrical signal Reverse Power Protection The Reverse Power Protection feature provides extra protection against accidentally connecting the power cables to the wrong terminal The converter is designed to automatically detect which power wire is positive and which is negative and then adjust the power supply accordingly DIP Switch Selectable Terminator For many products of this type the termination resistor is set by a jumper located inside the product s casing so that the user must open the casing to disable or change the resistor s strength Moxa offers a better solution The TCC 120 120I s terminator is set with a DIP Switch located on the outside of the converter s casing Auto Baudrate Detection The TCC 120 1201 incorporates a method for automatically detecting t
