    5 low-latency operation in normal mode it is possible to operate the adx-2400m in normal mode, but with low-latency transmission. Low-latency transmission reduces the path delay from one adx-2400m to another adx-2400m from approximately 7 milliseconds (standard mode) to approximately 2.5 millisecond...
