Network congestion can cause video glitches. AMX
recommends the Multi-Preview Live and Modero X touch
panel be installed behind a smart Ethernet switch to filter
multicast packets reaching the panel and consuming panel
resources.
The MXA-UENET video accelerator cable
(
FG5968-74/75/76
) may also improve performance in
cases of network congestion.

The MXA-UENET video accelerator cable
(
FG5968-74/75/76
) is strongly recommended for this
application.
Network congestion can cause video glitches. AMX
recommends the Modero X touch panel be installed
behind a smart Ethernet switch to filter unintended
multicast packets reaching the panel and consuming panel
resources.
Recommend maintaining aspect ratio of source and
following usage guidelines regarding window/button
placement.
• AAC <= 192Kbps @ 48KHz
• H.264 video 720p max (D1 for best results),
< 30fps max and a 4Mbps bitrate
• UDP Transport protocol only (RTP not supported)
• Multicast and/or unicast addresses
• SAP disabled
May require transcoding to H.264 baseline profile and
reducing resolution/ frame rate/bit rate per
recommendations above.
Recommend transcoding source material to MPEG2 if
Audio/Video sync issues still occur after following above
guidelines.
