Changing Channels
The 16x2 Frequency display presents the current Channel number on the top line,
as well as the frequency of the channel on the bottom line [see Figure 5 item E]. The
available Channel selection depends on the type of ODU and preset selected [ENG vs
SNG]. Refer to the Change ODU [RF Bands] section to learn how frequency bands are
selected, and Change Preset to determine how presets are changed.
You can scroll through the available channels in this frequency mapping for this particular
frequency and ENG or SNG mode via the rocker switch [see Figure 5 item G]. The
rocker increments the channel number. If you press the rocker switch until the end of the
list in one direction, the list starts again. The Enter channel button will blink amber when
viewing a channel that is different from the currently active channel.
Press the blinking
Enter Channel
button when you locate the desired channel [see
Figure 5 item I]. This will automatically turn off any RF transmitting device in NewS
tream
[PA on, Carrier on or Cellular On]. The button is lit green to indicate that NewS
tream
accepted the state change and is operating correctly. The 16x2 Frequency display
presents a message:
Channel Loading
on the fi rst line and
Please Wait
on the second
line.
Once the channel has been loaded, the amber button is lit green. The 16x2 Frequency
display presents the channel that you selected. Should the channel not be set, the Enter
channel button will blink red for 5 seconds and then stays red and an alarm will indicate
that there was a problem with the channel selection.
USB Interface
The USB interface [see Figure 5 item Q] provides a connection to upgrade system
fi rmware. Refer to
Software Upgrade Process
for more information. You have the option
of recovering your NewS
tream
system using the USB port to activate System Failure
Recovery. See the
System Failure Recovery Process
for details. You may also use this
port to export presets. Refer to
Modify Presets
for more details.
Ethernet Ports
The Ethernet ports provide to access a Web browser via a PC [or mobile devices] for
setup control and monitoring [see Figure 5 item R and Figure 6 (Ethernet I/O)]. There is
an RJ-45 port on the front panel and two RJ-45 Ethernet connectors on the rear. Any of
these three RJ-45 connections can be used to access
NewS
tream’
s Web interface.
