The bidirectional data interface ports can be used as control ports for equipment connected to the NET350 (for example, a dome camera with 
motorized lens). 

•

The COM1: RS232/422/485 port supports RS-232, RS-422, and RS-485 transmission protocols. 

•

The COM2: RS232 port supports RS-232 transmission protocols. 

 

 

 

 Transmission of transparent data is only possible when a video connection has been established.

 

The NET350 provides an audio channel through the Audio I/O jack. The audio signals are transmitted bidirectionally and simultaneously with the 
video signals. This allows control of a loudspeaker or door intercom system as required. Bidirectional, full duplex audio applies to box-to-box 
connections only.

1. Connect a preamplified microphone (monaural line) to the Audio I/O jack on the transmitter. 

2. Connect a loudspeaker to the Audio I/O jack on the receiver.
