Foreword
This user guide contains basic instructions for installation and operation of both Single and
Dual Channel DTX1 Modulators.
Please read through this document to determine how best to deploy the unit (location,
connections & settings) to suit your intended application.
1. Hardware Installation – Boxed Version
The boxed unit should be located indoors, in a reasonably well ventilated location and
away from direct sources of heat such as radiators, direct sunlight, or excessively hot
electronic equipment. The rear of a dual unit is arranged like this:
(Figure 1) Rear Panel
Connections are arranged in two horizontal rows. The lower row is always present on
both Single and Dual units, whereas the upper row is only present on Dual units. On the
bottom row, connections from left to right are as follows:
1 ‘F’ Connector UHF Output into 50 Ohms coaxial cable.
2 Barrel ROKA Plug 12V 1A DC PSU Input, Centre Positive (+).
3 Yellow PHONO socket Composite Video Input, PAL/ NTSC 75 Ohms
4 Mini DIN Socket S-Video Input, PAL/ NTSC 75 Ohms
5 White PHONO Socket Audio Channel LEFT input 10K Ohms
6 Red PHONO Socket Audio Channel RIGHT input 10K Ohms
7 RJ45 Socket Serial Connection to host - reserved.
(Table 1) Connectors Main
N.B. The group AV1 are the primary input feed.
4 Copyright 2013 Antennair Ltd BATC DTX1 (Iss 1.1)

On the top row from left to right connections are the secondary feed AV2 as follows:
1 Yellow PHONO socket Composite Video Input, PAL/ NTSC 75 Ohms
2 Mini DIN Socket S-Video Input, PAL/ NTSC 75 Ohms
3 White PHONO Socket Audio Channel LEFT input 10K Ohms
4 Red PHONO Socket Audio Channel RIGHT input 10K Ohms
(Table 2) Connectors (Expansion)
In the majority of cases, the only connections used will be DC Power, UHF RF output, and
Video and Sound inputs. You may select whether to use S Video or PHONO video inputs
in the menu options (see later). If a Stereo sound source is not available, using just one of
the two inputs for a Mono source will automatically feed audio to both LEFT and RIGHT
channels of the modulated output, but with reduced input impedance. For best picture
quality choose an S-Video picture source as opposed to composite video where possible.
In all cases use good quality screened leads. Make all connections before powering up
the unit.
The RF Output can be fed directly to a PA or depending on sensitivity you may require an
intermediate amplifier such as a MMIC block. Nominal full power out is -6dBm.
2. Bare Board Version
If you have purchased the 'bare bones' DTX1 board from BATC you will have to provide a
5 button keypad to operate it, or a serial cable to a host PC running a terminal program.
For more details of hardware connections and the serial command set, refer to
http://www.dtx1.info/ where you can also obtain the latest firmware upgrades and other
information.
2.1. BATC DTX1 – A Quick Guide to Getting Started!
2.1.1. Some words of Caution
Please note – the DTX1 PCB contains static sensitive devices. You should take
appropriate care to make sure you don’t damage it. Always work with an ant-static wrist
strap to discharge any static before touching the card even if it’s unpowered. Also, there
are switching power supply circuits on the board which convert the 12V DC input to
various low voltages, which should not be touched during operation (e.g. to see how warm
they might be!) as this might upset the sensitive feedback circuitry, and so cause
excessive voltages and damage to components. The general rule is – don’t touch the
board while it’s working, and don’t zap it while it isn’t!
2.1.2. Housing the Board.
The DTX1 PCB is made up of 6 layers, and contains quite a lot of copper to dissipate
unwanted heat from the various IC’s on it. When fitted in the extruded aluminium case
(also available from BATC) this heat is dealt with by conduction to the slide-in grooves at
the side of the case, and by conduction from the F connector to the rear panel to which it
should be affixed. We aren’t talking about a lot of heat here – the whole thing only takes
about 6 watts – but anything which can be done to reduce the operating temperature
BATC DTX1 (Iss 1.1) Copyright 2013 Antennair Ltd 5

makes for more stable and reliable electronics. So if you are using your own metalwork
(preferred over an ABS box) use metal stand-offs, bolts or whatever to mount the PCB,
and make use of conduction through the F connector, which will help keep the modulator
IC temperature down.
2.1.3. Powering the Board
Supply voltage is +12 Volts nominal, with the CENTRE PIN POSITIVE.
The board will operate reliably from 10 to 15V DC. We recommend a 1A PSU to have
something in reserve, especially you might be adding a secondary encoder at some point.
2.1.4. Controlling the Board
Either a simple keypad, or RS-232 serial commands, may be used. If the cased option is
being built up, this comes with an ‘Antennair Quadrant’ front panel membrane (the DTX1 is
a derivative of a commercially available unit). Simply plug the membrane ribbon connector
into the 6 pin connector on the PCB. If you are making up your own case, connect up 5
buttons (press to make switches) so that they all have one end in common. Wire as per
table below.

2.1.6. RF Output P3
Output is approx -5dBm into 50 Ohms from the 'F' connector at the rear of the board. Do
not short circuit, or allow static charges to damage the output circuit.
2.1.7. Audio and Video Inputs
1V Stereo Audio into 10K Ohms Red and White PHONO, and 1V Video into 75 Ohms
PHONO, or Y/C into 75 Ohms S Video Mini DIN connector. PAL and NTSC supported.

3. Menu Navigation
The menu system allows the user to set up various operating details such as Operating
Frequency, Logical Channel Number (e.g. 555), Time and Date, Video Source type and
Channel Name and so on.
The menu is navigated by a simple 5-button arrangement, whilst observing the LCD at the
left of the front panel. The centre key is the ‘OK’ or ‘Enter’ function.
The left, right, up and down buttons will be referred to as <, >, ^ & vrespectively.
The menu structure for the 'BATC DTX1' (and Antennair 'Quadrant', of which it is a
derivative) is shown in the next 3 pages.

When you first power up the unit, the RED LED will be illuminated and there will be a delay
of 10 seconds or more before any display appears. This is normal. After the internal
firmware has loaded you should see the default display:
N.B. The final part of this screen shows whether you have a single or dual channel unit.
Single channel units show a single arrow in the middle of the char on the display, the dual
channel unit will show two arrows (one above the other) in the char on the display. This
means the unit is up and running, (on a frequency less than UHF Channel 21) at a
frequency of 437.0 MHz. The GREEN LED will be illuminated.
Note: the LCD font depends on the panel used, and so may vary somewhat.
You can set up the unit using a 5 button keypad, or by means of commands over the
serial port (the serial commands are documented in section 5.1). For now we presume a
keypad is being used.
To change any parameter, press the OK button, which will invoke the menu system as per
previous diagram. The message
will appear, which invites you to cancel, either by doing nothing (time-out 20 seconds) or
by pressing the OK button once more. In this case the message
will be displayed momentarily before returning to the default display.
Let’s assume you want to change the default RF frequency. Press the OK button then
press the v (= down!) button until you get
Then press the OK button again which will take you to the menu section dealing with
modulator parameters.
You should see:

Press the OK button once more; the 1
st
digit of the frequency will flash, inviting you to alter
it. Use the ^ or vbuttons to increment or decrement this digit of the frequency, use the < &
> keys to select other digits of the frequency or UHF channel number to select the
frequency you want to use, then press the OK button followed by the < button to take you
back to the Modulator menu, and < once more then OK to return to the default display,
which will now show the new RF frequency and channel of your choice.
The above example demonstrates the way the menu system can be navigated. Up and
Down buttons change parameters, and Left and Right buttons select various options within
sub-menus, with the OK button confirming actions.
After using it a few times you should find it quite straightforward. Don’t be put off by all the
various modulator and encoder options, which are provided for specialist users; the factory
defaults will provide a viable system out of the box.
Furthermore, if you suspect that you have made some unwanted changes but aren’t sure
what they were, you have the option of returning the unit to factory defaults. This will undo
all the changes you have made, so use with caution.
To invoke factory reset, switch off power to the unit. Now press and hold the ^ and v
buttons at once, while re-applying power. Keep these two buttons pressed until the default
display shows, then release them. You should see the message
then eventually
N.B. For Dual units, there will be two arrows shown!
3.2. General Notes on Menu Options and Usage
Under GENERAL, set the unit's time to the time of day in GMT, and date to the present
date.
Under INPUT, choose the VIDEO SOURCE i.e. S Video or PHONO, for each AV input.
The DTX1 cannot auto detect which input to use. Also select whether you have a PAL or
NTSC source (the DTX1 cannot auto detect TV Standards, but it can have different
standards set on the two AV inputs, which is rather neat). For ASPECT RATIO the usual
(default) is AUTO. This will read the wide screen signalling information (WSS, where
present) in the video input and set up the picture accordingly. If you source has no WSS
present (half a line of dashes at the picture top left) then set manually to 4:3 or 16:9 as
required.
Under MODULATOR, set the required RF frequency or output channel, and adjust the RF
level setting to suit your PA and any intermediate MMIC amplifier stage.
Note: Outside of the menu structure, the UP key toggles RF ON and RF OFF.
Leave all ENCODER settings alone, unless for any reason you have a picture which is
14 Copyright 2013 Antennair Ltd BATC DTX1 (Iss 1.1)

4 7.0MHz [<21]-

noisy at source in which case you can try lower VIDEO FILTER settings, which affect
picture sharpness.
Under NAMES, choose and enter the displayed CHANNEL NAME for each video input
(AV1, AV2) and if required the common NETWORK NAME.
Under SERVICE, only edit the LCN as described above, for each AV input. (Just to re-cap,
these are the channel numbers as shown on a DVB TV).
Under NETWORK make sure this is not the same as any broadcast networks.
STATUS is an engineering readout of system performance and can be ignored.
