RS‑232 Mode — Drop-down list to select the RS-232 channel mode.
•
None
— The RS-232 pass-through port is disabled.
•
Pass through Server — Configures the device as a server.
•
Pass through Client — Configures the device as a client.
•
Data Channel — Configures the device to transport RS-232 communications over
the data channel.
NOTES:
•
In pass-through mode, RS-232 data is bi-directional and can be sent
and received between server and client devices. In this mode, RS-232
communications operate independently of device connections. Pass-through
communications cannot be recorded.
• In data channel mode, RS-232 communications operate over the current
connections and are uni-directional, from encoder to decoder. Data channel
communications can be recorded.
8
RS‑232 Server
— When RS-232 mode is set to Pass through Client provides a
drop-down list of available servers on the system.
9
Data Stream — Select Yes to enable the data stream, No to disable.
¢
UDP Data Rx — Select Enable to receive UDP data from the system. When enabled,
the UDP Dest IP and UDP Dest Port selections are listed below.
£
UDP Dest IP — The IP address of the external device or system that receives UDP
traffic. UNICAST or MULTICAST addresses are valid.
¤
UDP Dest Port — The port number used by the (external) device or system to receive
the UDP data.
¥
Annotation
— Select Yes to enable annotation pointer overlay functions.
NOTES:
• When creating a videowall using presets, VND 250 devices are configured
and connections are built using the
Preset Manager . Modifying the output
format or the scale mode settings of a VND 250 decoder in the Presets Device
Attributes panel changes the current configuration of the decoder in the Device
List to those set in the Device Attributes panel only when the preset is
launched .
• The normal encoder to decoder connection count limit applies.
• Unicast transport supports a maximum of four connections to a single encoder.
Note that each unicast connection increases the bit rate by the same amount
for each connection. The aggregate bit rate for four unicast connections cannot
exceed the maximum supported bit rate of 270 Mbps for an encoder.
• Multicast transport supports "one to many" connections allowing for wall sizes of
more than four displays.
See the
System Config Page
on page 28 for additional information on unicast and
multicast connections.
