*Ground may be required based on conditions of installation. Refer to the current version of EIA/TIA-422 

and EIA/TIA-485 standards for additional information.

•

TX (Out), TX+ (Out+), TX- (Out-), T+ (Out+), and T- (Out-) denote data output from the transmitter/
receiver.

•

RX (In), RX+ (In+), RX- (In-), R+ (In+), and R- (In-) denote data input to the transmitter/receiver.

•

W denotes white wire, and B denotes black wire.

•

Data ports are not terminated. For RS-422, RS-485 2-Wire, RS-485 4-Wire, Manchester, and 
Bi-Phase data signals, termination may be required based on conditions of installation. If 
termination is required, terminate the data signal at the endpoint of the data bus using a 120-ohm 
resistor.
