recommend to use our suggested p.s.u.
because GND andEARTH shouln’t be

connected. Please mount near to the
devices ferrite rings in the DC line, to
protect against electromagnetic

interferences.

To connect Local and Remote Units, please
use S/UTP (Cat5) cable acc. to EIA/TIA

56A or TSB 36 or Digital STP 17-03170.
Four pairs AWG 24. Pinout acc. EIA/TIA
568A (10BaseT). Screen must be

connected on both ends. To enhance EMI
resistance, both end should carry a ferrite
near to the connectors. Please be careful to

have a tension free connection!.

Hints for using CATx-Cables

The Local and Remote Units are interconnected by industry standard structured cabling
(Category 5, Cat5e, Cat6, Cat7 UTP/STP, 4-pair) terminated with RJ45 connectors. This cable is
not supplied with the Extenders. The cable used should be solid trunk cable. Stranded patch

cable will result in dramatically reduced Interconnection distances (only 60% of trunk cable).

Note: That failure to wire the twisted pairs correctly will impair the video quality dramatically and /
or prevent correct operation.

Although a single continuous length of interconnect cable is preferable, operation is possible
through multiple patch panels. However, the more patch panels the cable is routed through, the

greater the chance of video signal degradation.

Interconnection Cable: Fibre

Use for interconnecting the local and remote unit:

Multimode Modules: Two fibers 50μm or 62.5μm. E.g. I-V(ZN)H 2G50 (Inhouse patchcable) or
I-V(ZN)HH 2G62,5 (Inhouse Breakout cable) or I/AD(ZN)H 4G50 (inhouse OR outdoor Breakout

cable, stress resistant) or A/DQ(ZN)B2Y 4G62,5 (outdoor cable, stress resistant with protection
against animal biting) All notations acc. VDE specification.

Getting Started

The DAVX Extender consists of a Local and a Remote Unit interconnected by a fibre cable (2
fibres) or a single structured cable. The Local Unit is connected to the output of your video-/audio

source. The monitor and speakers are connected directly to the Remote Unit. Bidirectional
devices are local and remote unit at the same time. Local and remote unit are powered by a
power supply. Please remind, that all setup processes have to be done at the remote unit.

Exception: Cat5 devices with digital audio must be setup for Video Source and Video Format at
the local unit.

Connecting Up

Switch off your devices and power up the Local/Remote Unit by connecting the mains adapter

•

and switching it on. Only use the mains adapter supplied.
Connect the local unit to the Video-/Audio- Source, the remote unit to the Video-/Audio- Sink

•

and interconnect the devices with the Fibre-/Cat5- Cable.
Power on your Video-/Audio- Source, your Video-/Audio- Sink and check the data transfer.

•

Check that the IR Control functions.
Check that the Data Link LED on both units stays illuminated and the Data Error LED does

•

not blink..

We recommend, that the complete system is tested in one room before permanent
installation. If a long interconnect cable is not available, use a patch lead to test basic unit

operation with your PC.

All configuration and tuning is carried out using the IR Control at the Remote Unit. Setting up
bidirectional devices, it is always this channel to be updated, which is displayed at the attached
screen. Here you modify settings and parameters.

revision: January, 2004 DAVX - dig. A/V-Extender

Firmware Upgrade 27

Remarks to S/P-DIF Interface

The asynchronous transmission of the digital audio S/P-DIF interface (oversampling) adds jitter to
the signal. Serial connection of two pairs of vdeo extenders may increase this jitter to a not

tolerable value. This can induce audible errors. This error doesn’t occur with the analog audio
extender module.

Firmware Upgrade
and external Setup

In some special cases, it might be necessary to update the firmware of the system. Normally this
is to be done in the factory. Under some circumstances it might be possible, to do this by the
customer. In this case, you will receive from our support a programming cable and software.

Please follow the instruction of the program and the shipped brochure.

IR-Control

Please use the IR-Control displayed below to setup your extender system:

Monitor on/off

Video Input Select (Toggle)

FBAS or Y/C

Color Reset

Reset of Brightness and

Contrast to Standard values

Contrast higher

Contrast lower

Select DAVX Access

Video Format Select (Toggle)

brightness brighter

brightness darker

Usage of IR-Control

The system is modified by an Infrared remote control (IRC) type RC univers 15. With this remote
control up to 4 different devices can be controlled. For usage with the DAVX, at first the ‘Select

DAVX Access’ key has to be pressed. For transmission, the NEC Code 184 is used.

If this programming gets lost unintentional (e.g. empty batteries), the remote control can be
reprogrammed. To get into programming mode press [SET] and [TV] simultaneously. When the

red LED is on, release both keys, then input the three digit brand code: press [1], [8], [4]. After the
last key is pressed, the red LED goes off.

revision: January, 2004 DAVX - dig. A/V-Extender

28 Serial Interface (V24/RS232)

For adjusting video parameters of the DAVX, you have to direct the remote control to the current
remote device. This is always the device where the monitor is attached, which parameters shall

be modified. So you can follow the changings at the remote side.

Also the selection of the input signal Composite or S-Video is to be done at the remote side. If
there are two different video sources connected at both inputs simultaneously, it is possible to

use the device like a digital video switch. At the remote side Composite and S-Video are
delivered at the same time, independent of the type of connected source. The extender acts also

as an video converter from composite to S-Video and vice versa.

Changes made by remote control are immediately stored permanently in the extenders memory.
The key ‘Factory Reset’ at the remote control resets all DAVX settings to factory default values.

This key resets the changes for the local and the remote unit at the same time.

Serial Interface (V24/RS232)

No setting up or user adjustments are required.

Serial Interface – Handling Multiple Serial Devices

The extender’s serial interface transmits/receives six signals (3 signals in each direction).
Normally four of these signals are used for hardware handshaking (in addition to TX & RX).

However, because each handshaking line can support signals up to 19,200 Baud it is possible to
configure the serial interface to handle up to three simple 2-wire (Tx/Rx only) serial links. To do

this you will need to construct a custom breakout cable. Please contact technical support for
further information.

analogue AUDIO-Interface

The audio interface is line-level and is designed to take the output from a sound card (or other
line-level) source and be connected to a set of powered speakers at the other end of the link.
Stereo audio may be transmitted either way across the link (simultaneously). No set up is

required unless a microphone is connected to the remote unit.

Technical Data

AUDIO link:

Description : Bi-directional stereo audio link
Transmission Method : Digitised virtually CD quality audio (16-bit, 38.4KHz)

Signal Levels : Line-Level (5 Volts Pk-Pk maximum)
Input Impedence : 47K

Local Unit Connectors : 2 x 3.5mm stereo jack socket (Line In & Line Out)
Remote Unit Connectors : 2 x 3.5mm stereo jack socket (Line/Mic In & Line Out)
Microphone Support : A microphone may be connected to the Remote Unit

Pullup resistor provides bias for condenser microphone
Option to set microphone amplification to +17dB

Connect up the extender as follows:

Take the line-level output from your sound card (green connector) and connect to ‘Line In’ on

•

the extender.
A set of powered speakers may be connected directly to ‘Line Out’ at the opposite end of the

•

link.

Audio Interface – Using a Microphone

A microphone may be plugged into the ‘Line In’ connector on the Remote Unit.

There are two ways of setting up a microphone:

The Local Unit’s ‘Line Out’ connection should normally be wired to the microphone input (Red)

•

on your sound card. The sound card should then be set up to provide additional amplification
(+20dB). This is the preferred connection method.

Alternatively, the Remote Unit itself can provide microphone amplification. To set this, open up

•

the Remote Unit and locate the jumper labelled ‘MIC’ on the daughterboard. Connect this
jumper across the pins. The Local Unit’s ‘Line Out’ connection should then be wired to ‘Line In’
(Blue) on your sound card.

If your microphone is already amplified, follow the second method but DO NOT install the

•

amplification jumper in the Remote Unit.
