Product Description
AI Media’s DE551 HD NAS decoder enables affiliate stations to receive Network Alert System (NAS) messages and network time over an HD-SDI video signal. The NAS decoder features high-resolution video burn-in of NAS message data for display on an HD monitor, and works with a suite of custom, full-featured web tools for browsing messages remotely.
The DE551 is a full replacement for the EEG DE351 decoder, with features including automatic General Purpose Interface (GPO) tallies for an alarm connection, separate program and source video inputs, web-based browsing of stored messages and email distribution configuration.
Features
The DE551's features include:
- High resolution on-screen NAS message display
- On-board, non-volatile storage of NAS messages
- Front panel and web-based control for viewing stored messages
- GPO tallies for connection to an audible alarm
- Relay-bypassed program video chain
- Web-based inbox for browsing stored messages remotely
- Inbox auto-refreshes and highlights new messages as they arrive
- Live-updating virtual front panel reflects the status of decoder LEDs
- Diagnostic and configuration tools for software upgrades, and more
- Email notification module with configurable recipient lists based on HD message metadata
Setup
Front Panel
| PWR (Power On) LED | Lights BLUE when the unit is powered on. |
| Active Switch | Toggles the decoder between active operations and relay bypass mode. In relay bypass mode, the signal at the master video input is routed directly through to the master video output. |
| Active On LED | Lights GREEN when the unit is not in relay bypass mode. |
| Video Status LED | When active video is present, lights GREEN and the LCD displays the source video standard. |
| LAN Status LED | Lights GREEN when an Ethernet cable is connected and valid Network settings are configured. |
| Data Status LED | Lights GREEN when ABC Network time packets have been received. |
| Msg Status LED | Lights GREEN when a new NAS message has been received |
| LCD Screen |
The LCD screen provides access to the unit’s configuration menu. Status information displays when the menu is not in use. Press the Green Check Mark button is to enter the menu at any time. Press the X to return to the previous menu level.
|
| Control Pad | The control pad provides menu navigation for the configuration menus. The control pad buttons are: ENTER (marked by a check), CANCEL (marked by an ‘X’), LEFT, RIGHT, UP, and DOWN. |
| USB Port | The front panel’s USB port provides firmware upgrade capability via a flash memory device. You can apply updates through the USB port and the web interface. |
Rear Panel
| Primary Power 1 |
AC power input, 120 – 240 V, 50-60 Hz tolerant. Connects to the unit’s AC power source. Corresponding switch powers unit on or off. |
| GPIO | Two blocks of 8 GPI input switches on the top connector and 8 GPO output notifications on the bottom connector. Switch functions vary based on software configurations. |
| Ethernet Port | Connects the unit to your local network for access to the web interface. The decoder will be reachable on your network using the static or DHCP IP address set in the front panel configuration menu. |
| Master Video In | Video input for the program video chain. The on-screen display will be burned onto this video signal. The program video input will also be used as the source of NAS data if the Source video input is not connected. |
| Master Prog Out | Relay-bypass protected decoder video output |
| Master Mon Out | Non relay-bypass protected copy of the decoder output signal |
| Aux In | Reserved for future use |
| Aux Out | Reserved for future use |
| MDM | Reserved for future use |
| P2/RS232 Port | Reserved for future use |
| Audio | Reserved for future use |
Setup
To access features on the decoder web interface, select System Setup | Network Settings from the front panel LCD menu and configure the unit on your network:
- Use a Static IP address (recommended).
- Assign the gateway address – the gateway address is typically the local network address of your router.
- Enter your network’s Subnet Mask.
LCD Menu Options
Main Menu
| Silence Alarm | The audible New Message alarm is configured by connecting a wire harness contact closure on GPIO Pins 1 &2. The harness is then connected to a piezo for an audible alert. |
| View Messages | Displays the most recently received stored message. Press the left arrow to display the previous message or the right arrow to display the next message |
| Clear Messages |
Clears the current message from the on-screen display. |
| System Setup | Access the lower-level system setup menu items. |
Web Tools Suite
You can access the decoder’s web interface from any computer on your local network. The interface controls many of your encoder’s applications, configurations, and features.
You must connect the decoder to your network to access the web interface (reference Unit Setup | Network Setup). Once connected, access the web interface through the IP address assigned to your encoder in your computer’s webBrowser (ex. https://192.168.1.254).
System Time
Select Date/Time from the side menu on the web interface to set the date and time.
Alert Settings
You must provide the address of an SMTP server to the Email Distribution Module address of an SMTP server. The system uses this server to deliver email messages.
Configure the SMTP settings:
- Enter a Server Name for your SMTP sever in the Server Name field, for example smtp.example.com.
- Enter the connection Port for that server. This is usually 25, 2525 or 2082.
- Set the From field to the email address you want to use as the sender address of the decoder’s automatic emails. For many SMTP servers, this must a valid email address with an account on that server.
- If your SMTP server requires authentication, enter your SMTP server User Name and Password.
- Click Apply Settings to save your changes. Your settings take effect immediately.
Note: If your SMTP server is not on your local LAN, you must also configure the Gateway setting through the decoder’s front panel. The setting provides a network path for the decoder to send outside the local LAN.
Mailing List
The Mailing List feature provides the ability to configure email distribution for real-time message delivery. The module forwards each incoming NAS message to a configurable list of email addresses. The system sends NAS messages to recipients’ standard email addresses, with a header saying “NAS Message: {Subject}” for easy sorting and filtering.
Messages
The Messages module displays your stored NAS messages in an intuitive interface that you can view from any computer on your LAN.
