Ref Input:
This RCA or BNC connector is used to supply a reference signal to the converter
for mechanical standards. The signal can be a Line, Frame or Mains reference. The
input is DC coupled internally, and has an adjustable threshold settable in the Output
Settings Menu. This input is set to Auto Detect mode by default, and does not
normally need to be changed. For complete information about the characteristics of
this input, please refer to the Specifications section found later in this manual.
Composite Video Input:
This RCA or BNC connector is normally used to supply a composite NTSC, PAL
or SECAM video signal to the converter. The input is set to Auto Detect by default,
but can be overridden in the Input Settings Menu.
In addition, if the converter is set to the Bypassed mode, then the video signal on
this connector is sent to the RF modulator with no additional signal processing. Any
video signal can be supplied in this mode, although it is the users responsibility to
verify this video signal to obtain the desired result from the modulator. For complete
information about the characteristics of this input, please refer to the Specifications
section found later in this manual.
S-Video Input:
This Mini-DIN connector is used to supply an S-Video NTSC, PAL or SECAM
signal to the converter. This input provides a higher quality signal than the composite
input and should be used if available. The input is set to Auto Detect by default, but
can be overridden in the Input Settings Menu. For complete information about the
characteristics of this input, please refer to the Specifications section found later in
this manual.
Component Video Input:
These RCA or BNC connectors are used to supply a component NTSC or PAL
video signal to the converter. This input provides the highest quality signal and should
be used if available. The input is set to Auto Detect by default, but can be overridden
in the Input Settings Menu.
The component video signal can be of the type YUV, RGB or RGBS. (with RGBS
the composite video input is used for the S signal). Only a YUV type signal will be
recognized in the Auto Detect mode. If an RGB or RGBS source is used, it must be
manually selected in the Input Settings Menu. For complete information about the
characteristics of this input, please refer to the Specifications section found later in
this manual.

This RCA connector provides the processed audio output from the converter. This
output is delayed to matched the video output of the converter. For complete
information about the characteristics of this output, please refer to the Specifications
section found later in this manual.
Ref Output:
This RCA or BNC connector provides a reference signal from the converter. For
electronic standards, this can be a Field or Frame pulse, while for mechanical
standards it can be a Line, Field or Mains reference. In addition, the audio output can
be routed through this connector, and when used in conjunction with the optional
Reference/Current Driver option, can provide a signal to directly drive a loud speaker.
This is beneficial when used with mechanical televisions that normally do not have
audio facilities. For complete information about the characteristics of this output,
please refer to the Specifications section found later in this manual.
Composite Video Output:
This RCA or BNC connector provides the video output from the converter. This
signal should terminate into a 75Ωload. This output is the main video output from
the converter and is only valid when the converter is not set to Bypass mode. If the
converter is set to Bypass mode, no signal will be present at this output. For complete
information about the characteristics of this output, please refer to the Specifications
section found later in this manual.
Mechanical RGB Output:
This Mini-DIN connector provides an additional, simultaneous RGB output signal
for all mechanical standards. These signals should terminate into a 75Ωload. While
Introduction

the monochrome output will still be present on the composite video output, this
connector provides three separate outputs that contain the color information. For
mechanical standards that contain sync information, like that of the NBTV, the sync
information will not appear at this output, only on the composite output. For
complete information about the characteristics of this output, please refer to the
Specifications section found later in this manual.
Ref Driver Output (optional):
When the optional Reference/Current Driver board is installed, this Mini-DIN
connector will provide a 20W output of the signal on the Ref Output. This can be
used to drive phonic coils on mechanical televisions with the appropriate matching
transformer, or drive a loud speaker in Audio Passthrough mode. For complete
information about the characteristics of this output, please refer to the Specifications
section found later in this manual.
Mechanical Current Driver Output (optional):
When the optional Reference/Current Driver board is installed, this Mini-DIN
connector will provide three 333ma LED current drivers of the signals on the
Mechanical RGB Output. These three outputs can directly drive an RGB LED array
for full color mechanical television, or can be bridged together to drive a
monochrome LED array. For complete information about the characteristics of this
output, please refer to the Specifications section found later in this manual.
Power Output:
This DC coaxial connector is a switched output of the Power Input connector, and
used to supply power to external devices. It can be enabled in the Output Settings
Menu. For complete information about the characteristics of this output, please refer
to the Specifications section found later in this manual.
Power Input:
This DC coaxial connector is used to supply power to the converter. The amount
of power required is determined by the options and load connected to the converter.

Overview:
As a general rule, the Menu Control is used to scroll through the current level
menus, and by pushing the control, pop up to the previous menu. The Select Control
is used to scroll through the current settings, and by pushing the control, select the
current setting or menu.
The exceptions to this rule are when the converter is in the Idle Menu. From this
menu, the Quick Settings Menu is entered by turning the Menu Control. This is where
the most often used user settings are. Turning the Select knob from the Idle Menu
enters the Status Menu where various system status information can be displayed. By
default, all menus will timeout and return to the Idle Menu if no Control is adjusted
for one minute.
Most user settings are automatically saved in the user EEPROM when they are
changed by the user. The changes are updated instantaneous in the converter. There
are a few exceptions to this rule which require the user to push the Select Control to
accept the change. For instance, when swapping the functionality of the front panel
Controls, it would be confusing to make the changes instantaneous, so the user is
required to push the Select Control to make the change active. If the user changes
menus without pushing the Select Knob, then any setting changes will be disregarded,
and the converter will continue to operate with the original settings. These exceptions
will be pointed out below, and will be designated with a question mark on the LCD
screen of the unit.
Menus

Note: All settings are factory defaulted to the most appropriate values for each
standard. Typically the converter can be used with no other selections than the output
standard. The defaults can be restored at any time through the Advanced Menu.
Idle Menu:
This is the highest level menu, and is the menu the converter enters on power up
or when inactive. It displays the current output standard. No user settings are
available in this menu, but all other menus are entered from this state.
Output Settings Menu:
This menu is entered from the Idle Menu by selecting it with the Select Control.
Once in the Output Settings Menu, all specific aspects of an output standard are set.
All settings in this menu are unique for each standard, so making a change in one
standard will not affect other standards. The following submenus are available from
the Output Settings Menu:
Output Standard:
This submenu is always available, and is used to select the desired output standard.
When an output standard is selected, all previous user settings for that standard are
restored. Note that this setting purposely takes 2 seconds to become active. This was
done to eliminate erroneous outputs while scrolling through the output standards. For
complete list of available output standards, please refer to the Supported Output
Standards section found later in this manual.
RF System:
This submenu is only available when an electronic standard is currently active. The
desired RF System to be used for the RF Output is selected in this submenu. The RF
System along with the country it is most often used will be displayed on the front
panel LCD. For complete list of available output standards, please refer to the
Supported RF Systems section found later in this manual.

an RF System is selected. The desired RF Channel to be used for the RF Output is
selected in this menu. Any of the defined channels for the selected RF System can be
selected in this submenu. For complete list of available output standards, please refer
to the Supported RF Systems section found later in this manual.
RF Gain:
This submenu is only available when an electronic standard is currently active, and
an RF System and Channel is selected. The desired RF Gain between -12dB and
+20dB is selected in this submenu. Selecting too high of an output gain can overdrive
some televisions and result in a distorted signal, however a high output level can be
fed into a passive antenna splitter and used to feed multiple sets.
Color Type:
This submenu is only available when an electronic standard that is color capable is
currently active. The available color types for the current output standard will be
selected in this submenu. These will typically be of the type NTSC, PAL, SECAM,
RGB Sequential, etc.
Ref Input Type:
This submenu is only available when a mechanical standard is currently active. The
possible selections are:
Disabled - Reference input is ignored
Auto Detect - Converter will automatically determine the type of the source
Line Reference - Only a Line Reference will be recognized

The Mechanical Driver Output has a detection system that senses what is plugged
into the connector, and only allows the selections appropriate for the device. For
instance, if a monochrome LED array is connected, you would not be able to select a
color output. If a color LED array capable of 100ma/Channel maximum is connected,
than no setting above 100ma/Channel is possible. For complete information about this
submenu, please refer to the Reference/Current Option section later in this manual.
Gamma Correction:
This submenu is only available when a mechanical standard is currently active.
Gamma correction is required since standard video is pre-corrected for the
characteristics of a CRT, and is not compatible with LED or NEON lamps used in
mechanical television. If the device the converter is driving already has gamma
correction built in, then it can be disabled in the converter.
Output Polarity:
This submenu is always available and is used to select the polarity of the video
output. Normally this should be set to Positive. If the device the converter is driving
requires an inverted video signal, this submenu can be set to Negative.
Line Scan:
This submenu is always available and is used to select the Line scan direction.
When set to Normal, the Line scan will be in the direction appropriate for the selected
standard. If the device the converter is driving has the direction reversed, such as in
an electronic television with the scan coils reversed, or a mechanical set with the
motor running in the wrong direction, this can be set to Reversed.
Frame Scan:
This submenu is always available and is used to select the Frame scan direction.
When set to Normal, the Frame scan will be in the direction appropriate for the
selected standard. If the device the converter is driving has the direction reversed,
