UT-201 interface supports 2 communication modes as below:

 

1. Point-to-point 2 wires half-duplex

 

 

2. Point-to-multipoint 2 wires half-duplex

 

 

When converter works under half-duplex connection, it needs to install a matching resistance (data 120 ohm1/4W) for preventing signal reflection and interference.UT-201 half-duplex communication connect between interface converter
