Frequently Asked Questions - 775 MPEG-2/4 Cabletime

How do I configure the IP address of the 775 Encoder?

The default IP is 191.53.51.208. To change it, connect via RS232, USB, or Telnet using a terminal emulator (115200 baud, 8 data bits, 1 stop bit, no parity, no flow control). Use the command Setipconf with parameters for localaddr, netmask, etc. Alternatively, connect directly to a PC with a crossover cable and access the web interface at the default IP.

What video input sources are supported?

The encoder supports Composite (CVBS) via BNC, S-Video via Mini DIN, RGB or YPbPr component via 3 BNC connectors, and SCART (RGB with sync on Composite). Only one input type can be active at a time. Select the input in the Video Input menu of the web interface.

Can I use both MPEG-2 and MPEG-4 encoding simultaneously?

No, the encoder operates in either MPEG-2 or MPEG-4 mode at a time. However, when MPEG-4 is selected, you can enable Dual Encode which produces two simultaneous streams of the same source at different resolutions and bitrates (e.g., FD1 and CIF). This is set in the Encoder configuration page.

How do I reset the encoder to factory defaults?

There is no explicit factory reset mentioned. To restore settings, you may need to reconfigure manually via the web interface or command line. If the encoder becomes unresponsive, power cycle it and access the web interface at the default IP. Ensure your network adapter is set to a compatible subnet (e.g., 191.53.51.x).

What is the purpose of the Locator LEDs?

The locator LEDs cause the front panel LEDs to flash in a rippling pattern to help identify a specific encoder in a multi-unit rack. You can set the flash duration (Off, 5 secs, 2 mins, 20 mins) in the Locator Leds menu of the web interface.

How can I upgrade the firmware of the 775 Encoder?

Firmware upgrades are performed via the Software Upgrade page. You can enable hourly checks and specify the location of the HTP file server. The encoder will automatically check for updates and install them. During an upgrade, the MPEG stream LED flashes red.

What does the MPEG stream status LED indicate?

The LED is solid orange for MPEG-2, solid green for MPEG-4, and flashes orange/green if streams are disabled. A solid red indicates service required, flashing red indicates a software upgrade is in progress. The LED behavior helps quickly diagnose the encoder's operational state.

Can I secure the web interface with a password?

Yes. Go to the Set Password page and enter a 6-digit numeric password (0-9). Once set, all configuration pages and command interfaces (RS232, USB, Telnet) will require this password for changes. This prevents unauthorized access.

How do I connect the audio inputs?

Audio inputs are unbalanced stereo line level on two RCA connectors. Use standard RCA cables to connect your audio source. The impedance is 10kΩ. Only one stereo pair is supported. Ensure the audio source is line level, not microphone level.

What should I do if the encoder does not show a video input signal?

Check that the video source is powered and connected to the correct input. In the Video Input menu, select the appropriate input type (e.g., CVBS, S-Video, RGB, YPbPr, SCART). The corresponding LED on the front panel will flash if no signal is detected. Ensure the video format (PAL/NTSC) matches your source.

Quick Start Guide

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 qualified 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 airflow. Items that could accidentally block the ventilation grills or impede the cooling airflow 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 filled with fluid 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 flash 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 flash (orange or green depending on which is selected) if the network data streams have been disabled. It will flash red during a software upgrade, and will become solid red if the Encoder requires service support.

The Encoder's configuration 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.

Quick Start Guide

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-configured 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 reconfigured.

Reconfiguring 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.

Configuring 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.

Configuring 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 flow 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 satisfied 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 Configured With 'Auto-Negotiation' On.

Note that if the DHCP setting is used, following an Encoder reset, the unit may be given an IP address that is different from the one previously used.

Quick Start Guide

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 fields 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 configuration web pages, and will also prohibit changes being made through the RS232, USB or Telnet command interfaces (unless the password is specified 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 specifies the HTP file 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 flash in a 'ripling' sequence. This allows for identification of a specific Encoder in a multi-Encoder rack system. The location LED flash duration is: /Off /5 secs/ 2 mins/ 20 mins.
