NewStream User Guide and Technical Manual

All installations include an antenna, either directional, omni-directional or both. A legacy

Vislink RF switch can used on the antenna mast to select the antenna required or a

built-in RF switch when using NewStream ODUs can also be used. Antenna feed power

and control is available at the ODU via an 8 pin circular connector.

When using the mast-mounted antenna[s], a Nycoil conduit sheath covers the wiring

harness between the IDU and the ODU, as shown in Figure 4. The wiring harness

carries the DC power, IF control, and antenna band and polarization switching control.

Additional wiring is contained in the Nycoil conduit sheath for controlling the antenna

pan and tilt mechanism and for implementing additional functions such as off-air

monitors, mast lights, etc.

Operating Controls

All controls are located on the front panel of the NewStream IDU. Transmitter functions

are controlled using the OLED buttons and switches, as shown in Figure 5. The Liquid

Crystal Display [LCD] touchscreen controls Remote/Local control, ﬁ rmware upgrades

and IP addressing of the IDU.

Figure 5: NewStream IDU Front Panel Operating Controls

The LCD with touch screen, buttons and function keys are used to select control and

diagnostic menu screens for both the IDU and the ODU. Option buttons displayed on

the LCD are used to control Preset selection, RF band selection, channel selection,

antenna selection, antenna polarization, transmitter operation, power [low, high or

adjustable], and to monitor the status of the IDU and ODU. The option buttons displayed

on the LCD may be selected using either the color LCD display panel touch screen or

the function keys. Table 1 lists the functions and displays of the controls.

NOTE: When the IDU is shut down all the component variables are saved at the last

state with which the IDU was conﬁ gured. The exceptions to this are the following

states: Microwave Power Ampliﬁ er, Satellite RF Carrier and Cellular Cell Transmit

which always default to Off on IDU powerup.
