All SDI and Analogue black/burst outputs offer full control over timing and are individually selectable
for 525 / 625 standard operation.
Mentor XL is fitted, as standard, with an oven-controlled reference oscillator allowing the unit to be
used either as station master, or as a slave.
The main black/burst generator provides 5 independently timed outputs, giving total timing freedom
with adjustment of ±4 fields (±2 fields 525) relative to the main timing plane in 0.5 ns steps.
Additional software features are available to add HD-SDI capability, test patterns (for Analogue
and/or digital outputs), audio test signals, full field test patterns, LTC, VITC, D-VITC, ATC, NTP and
SNMP. Optional hardware options are available to add a GPS module for high stability time and
oscillator referencing, an HD tri-level sync option module and SDI option modules providing
additional SD, HD and 3G SDI outputs.
In addition, an internal redundant power supply is available to increase MTBF, or to allow AC power
diversity in critical applications.
An Ethernet port is provided for the Vector management feature, to facilitate software upgrades and
time synchronisation by means of NTP (Network Time Protocol).
This Instruction Manual concentrates on the operational aspects of the unit and includes a full
technical specification.

2. INSTALLATION
2.1 UNPACKING
Carefully unpack the unit from its transit material and check the unit for signs of damage. Check the
contents of the box against our despatch note and your original order to ensure that you have
received the correct parts.
In the event that the unit has been damaged or does not match your order, immediately contact
your supplier or Trilogy at the address given at the front of this guide.
2.2 RACK MOUNTING
The 1U rack frame has integral 19" mounting ears for direct mounting in a standard 19" rack.
Carefully place the unit in your rack and firmly attach it to the rack using 4 bolts.
IMPORTANT: This unit has air intakes on one side of the unit and fan assisted exhaust vents on the
other side of the unit. Ensure that these have an unobstructed air flow, otherwise the unit will
overheat. Pay particular attention to ensure that any rack wiring or cable trays do not obstruct the
vent. 60mm of clear space should be allowed between the vents and any potential obstruction.
2.3 EARTHING REQUIREMENTS
The unit is provided with a single 4mm earthing stud on the rear panel. Incoming mains earth from
the IEC connector is internally bonded to both the chassis and technical 0V to meet safety
requirements and performance specifications. The stud allows the addition of an earth strap, if
required, in rack installations.

2.4 MAINS CONNECTION AND FUSING
Important
Power Supply Cord Used as Disconnect Means
CAUTION: THE POWER SUPPLY CORD IS USED AS THE MAIN DISCONNECT DEVICE. ENSURE THAT
THE SOCKET-OUTLET IS LOCATED / INSTALLED NEAR THE EQUIPMENT AND IS EASILY ACCESSIBLE.
ATTENTION: LE CORDON D’ALIMENTATION EST UTILISÉ COMME INTERRUPTEUR GÉNÉRAL. LA
PRISE DE COURANT DOIT ÊTRE SITUÉE OU INSTALLÉE À PROXIMITÉ DE L’ÉQUIPMENT ET ÊTRE
FACILE D’ACCÉS.
The power supplies within the unit are a switched mode design and will cope automatically with a
wide input voltage range (see specification, section 17.3)
The standard Mentor XL is fitted with a single mains power supply unit (PSU), with an option to fit a
second PSU. Each PSU has its own, dedicated, IEC mains plug on the rear of the Mentor XL. These
should be wired according to the instructions provided with a mating mains socket using suitable
cable. See above for earthing requirements.
Mains cable conductors are to be three-core (two-wire with ground), wire gauge 18 AWG (cross
sectional area 0.75mm²) Jacket to be type SJT.
Covers are only to be removed by trained personnel. Shock hazard exists with covers removed;
therefore disconnect mains supply before removal. Interconnection between circuit boards and
panels are all safety extra low voltage (SELV) as defined by IEC/EN/CSA/UL 60950-1-200X. The
equipment signal connections must only be connected to SELV circuits to prevent hazards from
improper connection.

3.2 POWER ON DISPLAY
When the unit is powered, the LCD will display initialisation messages, as it configures the internal
hardware of the unit. Once initialisation is complete, a message indicating a normal operational
status is displayed, as shown below.
Mentor XL Main Menu
<Digital Video> Analogue Video Audio ->
The top line gives the name of this unit (i.e. Mentor XL). The lower line displays the first available
main menu items.
3.3 FRONT PANEL CONTROLS
The panel has four functional areas.
•A Liquid Crystal Display (LCD) used to show information to guide the user through operating the
various functions and show status information
•Front panel buttons:
oLEFT, RIGHT buttons for menu navigation
oOK and CANCEL buttons to execute or exit the currently selected option.
oRotary encoder for parameter adjustment and/or left/right menu navigation
oSDI button to access menus for main board SDI outputs
oANALOGUE VIDEO button to access menus for main board Analogue video outputs
oAUDIO button, to access menus for Analogue audio and AES audio outputs
oOPTIONS button to access option board menus
oLOCK MODE button to configure genlock modes
oSETUP button, for miscellaneous configuration options
oSTATUS button used to access diagnostic and status information
3.4 BASIC OPERATIONAL TECHNIQUE
There are a number of basic concepts, which once appreciated, will simplify the use of the
Mentor XL.
Valid button pushes are indicated by a lamp lit in a button. In most cases, buttons without a lamp lit
will not be prohibited, allowing rapid changes between functions of different types.
Invalid button pushes will result in an informative message on the LCD.
Page 17 of 84 Trilogy Communications

Mentor XL
3.5 SELECTING A FUNCTION
To change any parameter, the appropriate function button must first be pushed. Once a function
button is pushed, that button will illuminate to provide a reminder of which function is active.
Pushing a function button that has sub-functions under the first menu will cause the bottom row of
the LCD to show the lower level functions.
To choose which of these sub-functions is required, the encoder or left – right keys may be used to
step between the sub-functions. The current selection is marked with chevron symbols < >.
The top row of the LCD provides a fuller explanation of the function.
Once the required sub-function is selected, the OK button is used to choose it. Depending on the
sub-function chosen, either a further set of sub-functions or the current value of that function is
displayed. Where appropriate, the currently active option is indicated by square brackets (e.g. [ON]).
If the active option is also selected, it is indicated by asterisks (e.g. *ON*).
3.6 CHANGING VALUES
To change a setting, the encoder control or left – right buttons may be used.
In the case of numerical values there are two functional modes. If the overall range of adjustment is
small the encoder always alters the value by the smallest possible amount. If a wider range of
adjustment is required, a “Delta value” system is used. Use the left/right buttons to switch between
the setting and delta values and use the rotary encoder to adjust the selected value.
As the parameter is changed, the new value will be shown on the LCD. For some functions the unit
responds by altering that value immediately - it is not necessary to confirm or otherwise activate the
change. Otherwise the new value is applied when the OK button is pressed.
3.6.1 Leaving the Selected Function
Once the parameter has been set the unit can be returned to its normal operating mode, or another
function chosen by one of three methods.
Pressing the current (lit) function button will step up through the menu structure one level at a time.
Thus another parameter related to that function button may be changed without having to start
again at the top-level menu.
The OK button allows you to descend the menu structure and the current Function or CANCEL key
allows you to ascend the menu structure.
At any time, any other function button may be pressed to access a different menu. For example,
having set an OUTPUT CONTROL function, the SETUP key may be pushed without having to first step
back up through the menus.

3.7 MENU TIMEOUT
There is an in-built time-out mechanism that will automatically step back up through the menu
structure one level at a time, until the top level is reached, if a key is not pressed within a
pre-set time period.
The option to configure this feature is located under the Setup >> More >> Display >> Menu Timeout
menu.
3.8 FRONT PANEL LOCK
Front panel controls may be locked to prevent inadvertent changes of settings. To lock or unlock the
controls, press the LEFT and RIGHT buttons simultaneously.

3.9 TOP LEVEL MENU
The top level menu currently holds these branches:
Home: Top Level
Digital Video
Analogue Video
Audio
Lock Mode
Setup
Status
Options
The content and features of each branch are explained briefly below: a more detailed view of each
section is provided in later sections of this manual. Note that the Options branch (above) is only
displayed if hardware option modules have been installed.
3.9.1 Digital Video
The SDI menu provides full control of the configuration of each of the three SDI outputs. The video
standard, timing and appearance of each output are controlled from this sequence of menus. In
addition, the embedded AES audio is enabled and configured for each output. If the high definition
(HD) option is activated, additional choices will appear on this menu. For more details, see section 4.
3.9.2 Analogue Video
The video menu controls the format of the five Analogue video signals provided on the Mentor XL.
These are arranged as a group of three plus a second group of two outputs. This allows, for example,
the group of three to be set as RGB or YUV in a single operation. See section 5.
3.9.3 Audio
The audio menu controls both non-embedded AES and Analogue audio outputs. For all outputs,
control of frequency and amplitude is available. In addition, for each AES output, the sample rate
and source ident may also be configured. See section 6.
3.9.4 Lock Mode
The genlock input menu sets the required format of the incoming video signal and defines the
behaviour of the Mentor XL when the genlock signal is applied, or removed. See section 7.
