The MRX4000 PLUS is a fully functional, standalone, state of the
art ENG central receiver for analog and digital formats and
includes the ability to support encapsulated Internet Protocol (IP)
packetized service from an ENG or Outside Broadcast (OB) or
portable transmitter.

The MRX4000 PLUS is rack-mounted in a standard 19-inch
(48.3 cm) rack for fixed site operations.

The MRX4000 PLUS is used in both analog and digital ENG
central receive site operations. The unit allows operators to
switch between analog and digital operation modes where both
applications are used. The MRX4000 PLUS also provides
separate video and audio or broadband composite operation.

According to different applications, the MRX4000 PLUS can be
factory-configured as a baseband signal Frequency Modulation
Receiver (FMR) for analog radio applications, can be configured
as a baseband COFDM Demodulator and MPEG Decoder for
digital radio applications, or can be configured to include FMR

2. Set the power source off, as required.

3.4 Using the MRX4000 PLUS
Screens

Once the MRX4000 PLUS is set up using the Configurator
software and is powered up, you will be able to monitor and/or
change certain operating parameters through the use of the
menus displayed on the front panel alphanumeric display.

All options are dependent upon the actual configuration of your
MRX4000 PLUS and the Preset Operation Mode settings
established using the Configurator software. See ”Advanced

Operation” on page 5-1 for additional information on use of the

Configurator software (part of MRX4000 PLUS Technical
Reference Manual only).

The sections listed in Table 3-1 describe use of the menus.

3.4.1 Overview

As you use the MRX4000 PLUS, you will interact extensively
with the menus. The front panel alphanumeric display and
function keys provide you with the means to view and/or modify
operational parameters of the MRX4000 PLUS via use of the
menu pages displayed on the alphanumeric display.

The menu pages are organized in a hierarchy. The top level
menu is displayed upon power up of the unit and is returned to,
by default, when the user interface times out in approximately 30
seconds.

Menus will only display a maximum of three options. If a menu
contains more than three options, it will be necessary to scroll
through the options using the Up and Down arrow function keys.

The following are some points to make this easier.

The Main screen is your starting point for navigating through the
various menus. The Main screen provides access to the current
values of the Preset selected and the selected Preset options.

When power is applied to the MRX4000 PLUS, the Main screen
will be displayed. See Figure 3-5 on page 3-9.

The top level menu hierarchy is illustrated in Figure 3-6 on

page 3-10. From the top level menu page, the user descends

into the lower levels of the menu hierarchy until the operational
parameter required is reached.

Notes

If your MRX4000 PLUS does not contain an
MPEG, COFDM, RF/IF, or FMR module, or the
Preset operation mode selected does not include
MPEG, COFDM, RF/IF, or FMR, the >> cursor will
be replaced by a * cursor when the option is
selected.

Attempts to access those options will be ignored by
the firmware.

Illustrations reflecting individual menu hierarchy and the
associated options are listed in Table 3-2.

Each menu page has multiple selections available, with one
selection per line. Once the user has navigated to the menu
page required, the user can observe or change an operating
parameter, as required. To observe or change a parameter,
different cursors are displayed (See ”Cursors” on page 3-11),
indicating different options available to the user.

The selections available on any menu page can exceed the
number of lines physically displayed. The front panel firmware
creates a box that surrounds the complete set of lines on any
menu page.

As the user scrolls through the set of menu item lines using the
Up and Down arrow keys, the firmware also moves the
surrounding box graphics to indicate to the user that options are
available that are off the alphanumeric display, i.e., either above
or below what is currently displayed (See ”Accessing Menus” on

page 3-13).

3.4.2 Menu Configurations

The firmware determines which modules are contained in your
MRX4000 PLUS configuration upon power-up. The menus show
only those selections that are relevant to the user, based on the
current hardware configuration and Configurator software
settings.

Only options that are meaningful to the current chassis
configuration are displayed. In other words, if an optional
module is not contained in the MRX4000 PLUS, either the entire
menu page is not available or individual lines on a given menu
page are not available.

Additionally, if the Configurator software Preset operation mode
selected does not include MPEG, COFDM, RF/IF, or FMR,
attempts to access those options will be ignored by the system.

3.4.3 Main Screen

The Main screen is your starting point for navigating through the
various menus. The Main screen provides access to the current
values of the Preset selected and the selected Preset options.

When power is applied to the MRX4000 PLUS, the Main screen,
as shown in Figure 3-7, will be displayed.

Notes

If your MRX4000 PLUS does not contain an
MPEG, COFDM, RF/IF, or FMR module, or the
Preset operation mode selected does not include
MPEG, COFDM, RF/IF, or FMR, the >> cursor will

be replaced by a * cursor when the option is
selected.

Attempts to access those options will be ignored by
the firmware.

Figure 3-7: MRX4000 PLUS Main Screen - Typical

3.4.4 Cursors

The menu options will display several different cursors which will
change as various menu options are selected. The cursors are
identified as follows:

•The >> cursor, displayed to the left of a menu option,
indicates the option contains a sub-menu when selected.
Selecting that option, using the arrow keys and/or SEL
key, will bring you to the sub-menu.

For example, selecting >> MPEG Settings from the
Main screen menu, as shown in Figure 3-8, will bring you
to the MPEG Decoder sub-menu options, as shown in

Figure 3-9.

•The > cursor indicates the menu item selected contains
options that can be changed using the arrow keys and the
SEL key.

•The ! cursor will be displayed when a > menu option is
selected for change. It will also be displayed while the
arrow keys are being used to make option selections.

After pressing the SEL key to select the option or value,
the ! cursor will change back to a > cursor after
approximately 7 seconds.

If no arrow keys are pressed within approximately 7
seconds, the ! cursor will change back to a > cursor, and
the original option or value will be displayed. The SEL
key must be pressed to store any changes when the !
cursor is displayed.

•The * cursor will be displayed for menu items that are
read-only indications, for items that are currently inactive,
or for options that are not installed in the chassis.

When the * cursor is displayed, the item selected may
only be changed using the Configurator software or by the
factory.

If you press the SEL key when the * cursor is displayed,
the display will become locked on that screen to allow
you to observe status changes, i.e., to allow you to
monitor packet errors, etc. Pressing the ESC key unlocks
the display and returns you to the Main screen.

Changing Operating Parameters When the cursor is on an
operational parameter menu line that the user wishes to change,
and the SEL or Right arrow key is pressed, the cursor will
change and the firmware will enter the edit mode.

If the operating parameter requires values from a list of values,
the Up and Down keys provide the means to move through the
list of possible values. If the values are numeric, the Up, Down,
Left, and Right arrow keys provide the means to move through
the values in large or small steps.

The Up and Down keys move the values in larger steps, while
the Left and Right keys move the values in smaller steps. All
operational parameters have associated value ranges, defined
by upper and lower value limits.

There are two types of numeric values displayed: integers and
decimal. For example, if the operational parameter is a Preset
number, the keys allow selection of the Preset using the Preset
selection number.

When the correct value is located, the SEL key is pressed and
the value is recorded by the firmware and communicated to the
modules in the chassis. Further, the edit mode is exited and the
cursor changes from the ! cursor to the > cursor.

Menu Option Selections When making menu option
selections, the last option selected on the alphanumeric display
will be displayed when that menu is again accessed, unless
power has been removed from the unit.

When moving from menu to menu, it may be necessary to use
the arrow keys to move up and down through the menu options
to reach the option required.

Return to the Main Screen You can access the Main screen at
any time by pressing the ESC key until the Main screen is
displayed.

Default to Main Screen If you do not press the menu control
keys (SEL, ESC, or Left, Right, Up, or Down arrow keys) for
approximately 30 seconds, the display will automatically default
to the Main screen.
