N2151/N2251 User Manual
HDMI off on stream loss
Select to disable the video output drive when the video
stream is not available.
HDMI Enable
Select to enable output video.
Invert HDMI Horizontal
Sync
Select to invert the polarity of the horizontal sync
signal driven to the display device.
Invert HDMI Vertical
Sync
Select to invert the polarity of the vertical sync signal
driven to the display device.
Gratuitous ARP
Enable the Decoder to send a periodic Address
Resolution Protocol (ARP) packet to the network.
ARP Interval (secs)
Determine how often (in seconds) the unit transmits
gratuitous ARP packets.
Unsolicited Status
Enable the Decoder to send a periodic status packet to
the
Send Status Address
described below.
Send Status Address
When
Unsolicited Status
is enabled, the Decoder sends
a periodic status packet to the IP address specified
here.
Status Interval (secs)
Determine how often (in seconds) the unit transmits
status packets.
Discovery Packet
Transmit
Enable the multicast discovery service (which is used to
identify units).
This is useful for larger network integrations when
multicast packets will not cover the entire network.
Enabled by default.
Discovery Interval
(secs)
Determine how often (in seconds) the unit transmits
discovery packets.
Serial Master Enable
Enable this device to be the master to the
designated
client
.
The unit stops responding to outside RS232
commands when in Serial
Client
Mode. Can
be disabled to start responding again.
Serial
Client
Address
Enter the IP address of the serial
client
device.
IR Command Holdoff
Set the delay between IR command portions. The
default setting is 25 ms.
IR commands are sent in two parts. This setting is the
time (in milliseconds) between transmission of part
one and part two. The second part of the command is
inverted for confirmation purposes.
IR Repeat Holdoff
Set the repeat delay between IR commands. The default
setting is 90 ms.
This is the amount of time before a new command is
sent. For example, when pressing and holding the
volume button on a remote control, this is how long
until the command is repeated.
IGMP Joins on Stream
Loss
Enable to send Internet Group Management Protocol
(IGMP) join messages when no incoming stream is
detected.
IGMP Join Interval
Delay in seconds between sending IGMP join messages
(if
IGMP Joins on Stream Loss
is enabled).
Auto Sync Control
Enable synchronization of vertical sync with the
network.
Enable this option when using multiple Decoders (e.g,
when building a video wall) that must be
synchronized together.
Auto Sync Rate
Set the rate at which the vertical sync adjusts.
Maintain Aspect Ratio
When scalers are enabled, enabling this check box
maintains the source’s aspect ratio.
Enable SNMP
Enable to allow the device to send Simple Network
Management Protocol (SNMP) packets.
Interleaved Multicast
Stream
Enables a multicast format which interleaves video and
audio streams.
In order for N-Series devices to communicate with
each other, their multicast settings must be
compatible.
