NOTES:

 

 

 

 

 

 

 

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

 

receiver.

 

 

 

 

 

 

 

TX (Out), TX+ (Out+), TX- (Out-), T+ (Out+), and T- (Out-) denote data output from 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.
