5.2 Connecting the WP-121 

To connect the WP-121 as illustrated in the example in 

Figure 5

: 

Note

: Do 

not

 connect both the RJ-45 and terminal block connectors to receivers. If 

you do so, neither will work. 
1.  Connect the UXGA source to the PC IN connector (for example, a computer 

graphics source). 

2.  Connect the unbalanced stereo source to the AUDIO IN connector (for 

example, the audio signal from the computer graphics source). 

5.3 Grounding the Wall Plate 

Grounding the 

WP-121

 is recommended. 

The grounding wire is connected to the rear of the chassis of the unit.

Descriptions 

Item 

M3x6 Screw 

M3 Toothed lock washers 

M3 Ring tongue terminal 

 

Figure 6: WP-121 Grounding Components 

 

The grounding screw is used to earth the chassis of the unit to the ground of the 

building, thus preventing static electricity from interfering with the product’s 

performance.

 

To connect the grounding to the WP-121 as illustrated in 

Figure 6

: 

1.  Crimp the ring-tongue terminal to the building grounding point wire.  

(We recommend that you use a green-yellow #18 AWG wire (0.82mm

2

crimped with a proper hand-tool). 

2.  Insert the M3x6 screw through the toothed lock washers and the ring-tongue 

terminal in the order shown above. 

3.  Insert the M3x6 screw (with the two toothed lock washers and ring-tongue 

terminal in place) into the grounding screw hole on the rear of the 

WP-121

 

and tighten the screw.
