Installation

WARNING: There are no user serviceable parts within
the MediaStar Evolution Encoder. This unit contains
hazardous (mains) voltages and should only be
opened by suitably qualied service personnel.

When locating the Encoder unit, ensure that a clearance
distance of 25mm (1”) is maintained at the front and
rear of the unit to allow free ventilation airow. Items
that could accidentally block the ventilation grills or
impede the cooling airow must not be located near
the unit. The Encoder must not be installed where there
is a possibility of exposure to condensation, dripping or
splashing liquids, and containers lled with uid should
not be located in the vicinity of the unit.

Using the AC mains power cable supplied, plug in the
Encoder. This device must be installed using a mains
(AC supply) plug and socket that contains a protective
earth (ground) connection. The mains socket must be
located near the equipment, remain operable and be
easily accessible to disconnect the unit in the case of
an emergency.

Ensure that the blue Power LED is lit, showing that
power is on. All the LEDs on the front will turn on and
then off after approximately 30 seconds but the blue
Power LED will stay lit, along with the video input
indicator and the MPEG stream status LEDs.

The video input indicator LED shows what type of video
input is selected: RGB/YPbPr, SCART (RGB with sync on
Composite), CVBS (Composite), or S-VIDEO. The selected
LED will ash if there is no input signal detected.

The MPEG stream status LED shows what type of
encoding standard is selected. Solid orange indicates
MPEG-2 and solid green indicates MPEG-4. This LED will
ash (orange or green depending on which is selected)
if the network data streams have been disabled. It will
ash red during a software upgrade, and will become
solid red if the Encoder requires service support.

The Encoder’s conguration is set using web pages
served by the Encoder unit. A network connection is
required to view these and a suitable IP address will
need to be assigned.

Connecting Video And Audio Inputs

Only one type of video input source can be selected
at a time, either RGB/YPbPr, SCART (RGB with sync on
Composite), CVBS (Composite) or S-Video. When YPbPr is
selected, the RGB LED will be lit. Stereo audio inputs are
unbalanced with 10k ohm impedance.

Selecting IP Address

A suitable IP address for the Encoder should be selected
before it is connected to a network. The Evolution 775
Encoder is pre-congured with a static IP address of

191.53.51.208, however if this is not suitable for use
on your network the Encoder must be recongured.

Reconguring the Encoder IP address can be achieved
using the RS232, USB, or Telnet Command interface, or via
a browser application such as Internet Explorer connected
locally to a PC with a Cat-5 network crossover cable.

Conguring With A Browser Application

Using a browser such as Internet Explorer, type the IP
address (http://191.53.51.208) into the browser
window and the Evolution Encoder Admin window will
open. This allows entry and adjustment of all Encoder
operational parameters such as network setup, video
input, encoding stream, and password protection.

Conguring With RS232 Serial Or USB
Communications

Plug the supplied cable into the Encoder’s RS232
interface and connect with a laptop/PC. If this is not
available a USB interface may be used. A CD supplied
with the 770 rack contains the appropriate USB driver
software to install a USB ‘com’ port onto a Microsoft
Windows 2000 or XP platform when there is no RS232
serial port available on the laptop/PC.

Use a terminal emulator program (e.g. HyperTerminal)
to issue commands. The serial communications settings
are: 115200 Baud, 8 bits data, 1 stop bit, no parity,

no ow control.

To set the static IP address, use the command:

Setipconf, mpeg_encoder=”Encoder1”,
localaddr=192.168.66.10,
localnetmask=255.255.255.0,
gatewayaddr=0.0.0.0, dnsaddr=0.0.0.0, dscp=0

In the command response you will see that

status = “0” and statusstring = ”Success”

Connecting To The Network

Only when you are satised that the IP address of
the Encoder is suitable, plug the Encoder into the LAN
using the RJ45 patch cable supplied. The RJ45 LEDs will
illuminate to indicate a network connection.

Important : Ensure That The Encoder Is Connected To A
Network Port Congured With ‘Auto-Negotiation’ On.

Evolution Encoder Admin

These HTML conguration menus allow you to enter
and adjust all Encoder operational parameters. Full
contextual HELP is provided on the right side of the
screen. When alterations and changes have been made,
press the APPLY button at the bottom of the page to
make these take effect. The Encoder conguration
menus include:

Status

Shows the current status of the Encoder, including:
encoder network name, serial number, encoding
standard, video source present status, stream details,
IP address, video input selected, software/hardware
versions, and enablement codes entered.

Encoder

Allows selection of the video encoding standard, either
MPEG-2 or MPEG-4. MPEG-4 provides a similar picture
quality as MPEG-2 but at a lower network bandwidth.

Enablement Code

To upgrade the Encoder with an additional feature (e.g.
additional type of video encoder: MPEG-2/MPEG-4) a
suitable enablement code must be obtained from your
reseller or Cabletime. This 15-digit number is entered
into the elds on this screen. The Encoder will validate
the code and enable any appropriate feature. Note that
all enablement codes are unique to an individual unit.

Set Password

A password will prohibit unauthorised access to all
the Encoder conguration web pages, and will also
prohibit changes being made through the RS232, USB
or Telnet command interfaces (unless the password is
specied in each command). Valid passwords consist
of six numbers 0-9.

Software Upgrade

Encoder software may be upgraded to facilitate new
functionality or provide support related upgrades. This
screen enables hourly upgrade checks and species
the HTP le server location that the Encoder will check
for upgrades.

Locator Leds

The locator LED functionality causes the LEDs on the
front of an Encoder to ash in a ‘rippling’ sequence.
This allows for identication of a specic Encoder in
a multi-Encoder rack system. The location LED ash
duration is: /Off /5 secs/ 2 mins/ 20 mins.
