EN537 Smart Encoder

Introduction

Product Description

The EN537 is an affordable caption encoder for broadcasters requiring basic caption insertion features. The unit offers Automatic Captioning services through our cloud-hosted captioning service Lexi, supports a direct serial port or TCP/IP connection, and can be also be equipped with an optional telco modem.

Please note the EN537 unit does not support using iCap to connect to captioners. However, an iCap account is required for your EN537 to communicate with Lexi over a broadband connection.

List of Features

 Connectivity to EEG’s Cloud-hosted Automatic Captioning service, Lexi.  Encoding of caption data sourced from previously encoded video sources, two RS232 serial ports,

or a dial-up modem (optional)

 Encoding of CTA-708 standard closed captions from native 708 or legacy 608 (SD) sources  Caption relocation from configurable GPI triggers  Modules for web-streaming, scoreboard connectivity, and much more.  Local logging of caption input for future reference  Relay-bypassed master video and auxiliary video paths

Encoder Setup

Quick Network Setup

To use Lexi or access further features on the encoder’s web interface, you must first select Network Settings from the front panel LCD menu and setup the encoder on your network.

 Use a Static IP address on your network to assign the Encoder (recommended). It doesn’t

have to be, and in most cases should not be, a publically routable IP address.

 Program a gateway address – the gateway address is typically the local network address of

your router. This is necessary if you plan to connect out of your local network to iCap or any other application from the iCap Encoder.

 Program a Subnet Mask for your network  Lexi only: Program your network to allow outbound connections to https://eegcloud.tv on

port 443. Your encoder must also have a valid DNS server configured under the Network tab on the web portal. See additional Lexi setup instructions on Page 6.

As an alternative to these recommended steps you may also set up the encoder for DHCP – Selecting DHCP will automatically pull available IP, gateway, and subnet information from your network.

IMPORTANT: With DHCP, your encoder’s assigned IP may change on its own which will affect how you access the web interface for your encoder.

Video Input/Output

Put SDI video into the encoder. Output captions will appear on the SDI video output. Reference the

Rear Panel Diagram located in the Hardware Reference for a diagram of the rear-panel connector.

Test Captions

With video input connected to the encoder, you can send a stream of encoder-generated test captions to the output video to ensure proper initial setup of the encoder. To send test captions navigate to Utilities > Test Captions > Enable > On and a stream of test caption text should appear on the output of your encoder. Note that video input is required to send test captions.

Setting Audio Levels

Your program audio source is typically embedded in the standard video input to your encoder. Audio may also originate from a separate Analog or AES source (XLR connector input to encoder). To send this program audio to captioners through iCap, you must first configure the audio settings through the front panel menu of the encoder.

From the main menu go to Audio Setup > Audio Mix and set to Stereo or Surround appropriately. Next, visit Audio Setup > Peak Level and ensure the audio level peaks at around 80% and does not warn “Clipping!” This step is crucial for ensuring that quality audio is being sent to the captioner (quality audio = quality captions).

If your audio levels are too low, or too high – you can achieve an appropriate level by adjusting the audio source itself or simply adjusting the source audio level from the encoder front panel LCD menu Audio

Setup > Scale Audio which allows you to scale the audio up or down in 6 decibel increments.

Accessing Your Encoder’s Web Interface

Your Encoder’s web interface can be accessed through any computer on your local network and controls many of your encoder’s applications, configurations, and features (see Security Settings and Password Protection below for instructions on how to secure access to the web interface). You will see it referenced many times throughout this manual.

The encoder must be connected on your network to access the web interface (reference Quick Network Setup section on page 3). The web interface is accessed by entering the IP address assigned to your encoder in your computer’s web browser. If you set the encoder up with a static IP address, the address for your web interface will be the same. If you set the encoder up with DHCP, the address can change at will and you should check the IP from the front panel of your encoder at System Setup > Network > IP Address to ensure you are using the correct IP to access the web interface.

Security Settings and Password Protection

To limit access to the encoder’s web interface for security purposes, you may set up a password through the front panel of your encoder via Setup > Security > Security Mode > Password. This password will be for access to the encoder’s web interface, not the encoder LCD menu. Many of the encoder’s crucial features are controlled via the encoder’s web interface.

Setting Date & Time

The Date and Time can be set by selecting Date/Time from the side menu on the web interface.

Updating Your Encoder

Before updating you must first download the latest update file for your encoder model from the product updates section of our website https://eegent.com/support/product_updates

Once you have downloaded the latest version for your encoder model you can apply it to the encoder either through the web interface OR the front panel USB port / LCD Menu.

 Web Interface: Select Update from the left side menu. Browse for the update file

downloaded from our website, then click Upload, and finally click Proceed.

 USB / LCD: Transfer the update file to any USB stick. Insert the memory stick into the front

panel USB port, navigate to the System Setup > Update from the LCD menu, and press enter to proceed and install the update. A message will appear on the LCD screen when the update has finished. Do not remove the memory device while the update is running.

Some updates will require a power-cycle before they take effect; in this case, the encoder will power down automatically once the update is complete.

Lexi Setup and Testing

If you did not indicate interest in Lexi at the purchase of your encoder, please contact EEG technical support at 516-293-7472 to obtain the necessary iCap and Lexi / EEG Cloud credentials. Also, be sure your EN537 is properly setup on your network prior to setting up Lexi (instructions on Page 3).

Please note the EN537 unit does not support use of iCap to connect to captioners. However, an iCap account

IS required for your EN537 to communicate with Lexi over a standard broadband connection.

1. Confirm iCap Connectivity and Know Your iCap Access Code:

 From the main page of EN537 web interface, confirm the iCap Status says Connected to

remote server. If inactive, contact EEG support for credentials.

 Your iCap Access Code can be found in the shipping documentation provided with your

Encoder. This will be used in the next step to enable Lexi to access live program audio from,

and return automatic captions to, your encoder over iCap.
