Chapter 2 – Operation
Default Operational Settings
The 3G-AM converter ships from the factory with the following configuration:
• Local (DIP switch) control.
• Input AES audio channel pairs 1/2, 3/4, 5/6, 7/8 are embedded to SDI output
channel pairs 1/2, 3/4, 5/6, 7/8, overwriting any existing embedded audio.
• Input SDI embedded audio channel pairs 1/2, 3/4, 5/6, 7/8 are disembedded to
AES audio output channels 1/2, 3/4, 5/6, 7/8.
• All HANC packets pass from SDI input to output, except for embedded output
audio channels 1/2, 3/4, 5/6, 7/8.
If these settings apply to your requirements, you can simply connect the video
and audio input and output signal cables and power up the unit.
For other applications, you can configure the unit using its DIP switch settings, or
by using the Mini-Config application and a PC or Mac via USB.
DIP Switches
The 3G-AM DIP switches configure the audio embedding and disembedding
functions, and control ancillary data.
DIP Switch Settings
DIP switch settings used to configure various functions are described below.
