1.  Connect 3.3V DC power and ground of the board to JP12 from the power supply (3.3V on left pin, ground on right 

pin). Connect 1.8V DC power and ground of the board to the J5 and J6 from the power supply respectively. 
 

2.  Attach the USB cable to the TX board (DS92LX2121) output and to an RX board (DS92LX2122) input. 

 

3.  Attach parallel data and clock to the TX board at connector J1. This is typically done with a flat ribbon cable (not 

supplied). 
 
 

4.  Connect 3.3V DC power and ground of the board to JP13 from the power supply (3.3V on left pin, ground on right 

pin). Connect 1.8V DC power and ground of the board to the J8 and J9 from the power supply respectively. 
 

5.  Attach the USB cable to the RX board (DS92LX2122) input from a TX board (DS92LX2121) output. 

 

6.  Attach parallel data and clock output to the RX board at connector J7. This is typically done with a flat ribbon cable 

(not supplied). 
 

Jumpers and switches on both the TX and RX boards have been configured at the factory; they should not require any 
changes for immediate operation.  See the datasheet for more details.
