Serial Control

Serial passthrough allows data to be sent from a device attached to the serial port of a transmitter to
device(s) attached to the serial port of the primary receiver or all bound receivers. Conversely, data
arriving at the serial port of the primary receiver will be forwarded to the transmitter and made
Then choose...
Receiver Video Latency and Receiver Audio Latency settings on the
receiver Tuning Parameters web page. Figure 4.2 on page 46 illustrates
these settings.
Default value for this parameter is 200ms. This delay provides an elastic
buffer of roughly 7 frames, allowing receivers to remain in lock step even
if lost packets need to be retransmitted. Increasing either of these
parameters will allow you to adjust audio and video playback across
display devices.
Reducing receiver latency below the default of 200ms may compromise
synchronization across receivers. However, in applications consisting of
one or two receivers, it may be desirable to reduce this value if the
primary application involves mouse-driven presentations that are
sensitive to latency. If choppy video occurs on one or more receivers,
raise the value until smooth video is obtained.
