WISI OE 01 Encoder Modulator

Introduction & Product Description

The WISI OE 01 Encoder Modulator converts your local HDMI source into an RF signal, compatible for distribution via coaxial networks. The HDMI video signal is compressed using MPEG-4 and can be received by TV sets with an integrated MPEG-4 compatible receiver. The output supports all common terrestrial and cable TV modulation standards and can be selected at the device without additional effort.

Key Features:

• 1 HDMI input supporting all resolutions up to 1080p60
• 1 RF loop-through input to insert existing DVB-C/T signals
• MPEG-4 video compression
• Switchable output modulation (DVB-C, DVB-T, DTMB, and ATSC-T/C)
• Freely selectable output frequency up to 1218 MHz
• User-friendly programming without additional software/hardware
• Adjustable NIT/LCN parameters
• Compact dimensions and easy installation

Hardware Installation

Front and Top View of the Product

The WISI OE 01 Encoder Modulator is a compact device. Its front panel features a digital display showing "Input: 1080P60 DVB-T 594.0 MHz". It also has connection ports labeled "+12V", "HDMI IN", "BYPASS IN", and "RF OUT". Regulatory marks like CE are visible. The device has numbered indicators:

1. Display: Shows device information.
2. Grounding: Terminal for grounding connection.
3. Power Connector + LED: For power supply input and status indication.
4. HDMI Connector: For connecting the HDMI input source.
5. Rotary-Push Button: Used for menu navigation and selection.
6. RF Bypass Input Connector: An F-type connector for inputting existing RF signals.
7. RF Output Connector: An F-type connector for the modulated RF output signal.

Connections:

• Connect the grounding cable to the grounding terminal (2).
• Connect the 12V power adapter to the power jack (3).
• Plug the power supply into the 230V socket.
• Connect the HDMI output of your video source (e.g., Blu-Ray player, DVD, satellite receiver) to the HDMI input (4).
• Connect your TV to the RF output connector (7).
• Optionally, connect an existing coaxial distribution network to the RF Bypass input connector (6). This combines the modulated HDMI signal with the existing coaxial network signal at the RF output (7).

Operation & Settings

First Use

Follow these steps for initial setup:

• Connect the grounding cable to the dedicated grounding connection (2).
• Connect the 12V power adapter to the power supply socket of the OE01 (3).
• Plug the power supply into the 230V socket.
• Connect the HDMI output of your video source to the HDMI input (4).
• Set the desired output channel via the rotary-push button (5).
• Insert the Encoder Modulator into your distribution network using the RF output (7).
• Existing terrestrial or cable TV channels can be combined via the RF Bypass (6).

Indication

The integrated display (1) shows all information about the Encoder Modulator. The Power-LED indicates the presence of DC power (permanently glowing).

Software Settings

All settings are made using the rotary-push button:

• Press and hold the button for 2 seconds to enter the main menu.
• Press the button to confirm your selections.
• Rotate the button to scroll through different menu items and parameters.

Important: To save all changes, select "Save & Exit" at the end of the programming process.

During operation, the display shows the most important parameters:

• The first row indicates if an HDMI signal is detected and its resolution. If no resolution is shown, the HDMI signal is not recognized.
• The second row shows the selected output modulation and output frequency.

Configuration

Basic Configuration

This section guides you through the basic configuration for initial use. In most cases, this is sufficient. For special cases requiring detailed settings, refer to the advanced configuration section.

The best way to configure the product is to follow the menu step-by-step. Some settings affect multiple subsequent settings. For example, selecting "France" as the country may automatically change the output type from ATSC-T to DVB-T, as ATSC is not supported in France.

Step 1: Country Selection

Display: Input: 1080p60 DVB-T 594.0 MHz

Action: Press and hold button for 2 seconds.

Menu Item: Country: France

Explanation: Configuring the modulator and TVs to your country ensures better performance, particularly for channel order (LCN). If the country settings of the modulator and TV do not match, LCN may not function correctly. Choosing the correct country also simplifies other settings by pre-configuring channel plans, LCN, ONID, SID, and TSID. Selecting "Other" indicates that advanced settings have been manually modified.

Note: The country selection determines the available output types and channel plans. For instance, ISDB-T is not available in France. It is advised to follow the menu step-by-step.

Step 2: Output Type Selection

Menu Item: Output Type: DVB-T

Explanation: The output type defines the standard of the modulated output signal. Depending on the product reference, this can be DVB-T, DVB-C, DTMB, ATSC-T, ATSC-C, or ISDB-T. The available standards depend on the selected country.

Step 3: Channel/Frequency Selection

Display: Channel: 36 (594.0 MHz)

Explanation: This parameter determines the output frequency of the modulated signal. If a channel plan exists for your country and selected output type, you can choose a channel. Otherwise, you must set the frequency directly. For example, if "DVB-C" is selected, the frequency will be displayed.

Note: The channel plan depends on the country and output type.

Step 4: Output Level

Display: Level: 80 dBμV

Explanation: This determines the RF output level of the modulated signal, ranging from 59 to 99 dBμV.

Note: dBm can also be used (see Advanced > Preferences).

Step 5: Channel Number (LCN)

Display: CH Number (LCN): 594

Explanation: LCN allows you to determine the position of the modulated channel after an automatic TV scan. LCN typically copies the frequency but can be manually modified.

Step 6: Channel Name

Display: CH Name: Modulator

Explanation: This is the name displayed on the TV screen. Maximum 15 characters (letters, numbers, -, _, space). Scroll to the underlined arrow to confirm.

Step 7: Advanced Settings

Action: Navigate to "Advanced".

Explanation: See section "2.2 Advanced Configuration" for details.

Step 8: Save & Exit

Action: Navigate to "Save & Exit".

Explanation: This will activate and save the new settings.

Advanced Configuration

This section details the advanced configuration options for the HDMI Modulator. These settings are typically not required for most installations.

Audio Parameters:

Stream Parameters:

Note 1: If you cannot reach a specific bitrate (e.g., 18.000 Kbps), you may need to adjust "RF Output" settings like constellation (e.g., 64QAM), guard interval (e.g., 1/32), and/or code rate (e.g., 7/8).

Note 2: Changes are saved and activated after selecting "Save & Exit".
