Sync Signal Output Connector 

The sync signal output connector is a BNC connector that transmits composite sync signal 
(CS), horizontal drive signal (HD), and vertical drive signal (VD). The connector transmits 
signals in any format (see Table 12-3, “List of output connectors”). 
The following figure shows the output connector. 

 

 

Figure 7-9    Sync signal output connector 

 

You can set the polarities of the horizontal drive and vertical drive signals for each output 
format according to the procedures described in section 8.17.6, “USER SETTING Feature.” 
Connect a 75-

Ω

 coaxial cable to the sync signal output connector. 

 

7.10 

Audio Signal Output Connector 

The audio signal output connector is an RCA connector that transmits audio signals. The 
connector transmits audio signals that you set according to the procedures given in section 5.5, 
“Setting the Audio Signal.” 
The following figure shows the output connector. 

 

 

Figure 7-10  Audio signal output connector 

 

You can select the audio signal output level by setting AUD OUTPUT in the menu screen to 
0dBm or -5.23dBm. For details, see section 8.15.1, “Audio Signal Level.” 

 

Connect a commercially-sold RCA cable to the audio signal output connector, and terminate 
the other end of the cable with 600-

Ω

 termination.
