KB03000: How to Configure OmniStream Display Control

SKUs: AT-OMNI-111, AT-OMNI-112, AT-OMNI-121, AT-OMNI-122, AT-OMNI-111-WP, AT-OMNI-512, AT-OMNI-521

 

How to Configure OmniStream Display Control:

 

Controlling downstream devices (TV)

 

Pass-Through

Control input over RS-232 is converted over IP by encoder. Destination device can be the IP address of display end point or decoder.

  1. Navigate to web interface Serial tab of encoder.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port and set mode to Not used:

  1. Navigate to web interface Session tab.
  2. Under AUX control, select desired source serial_port#.
  3. Define the Destination IP address and UDP port of the decoder, or IP address of display:

  1. If decoder in step 6 is chosen, navigate to the IP Input tab of the decoder.
  2. Enable an INPUT, e.g. INPUT 5, with no Multicast address defined, and Port set to that in step 6:

  1. Navigate to web interface Serial tab.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port and set mode to output:

TCP Proxy

TCP/IP traffic received by encoder or decoder on defined IP:Port socket are translated to RS-232, allowing both control of source or display. Control is achieved using a control system, where all control commands are stored.

  1. Navigate to web interface Serial tab.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port and set mode to tcpproxy.
  4. Define ethernet interface and TCP port to listen on:

NOTE: Configure decoder if control of display is desired, and configure encoder for control of source.

 

 

Triggered

Display commands are stored in encoder or decoder, and are triggered through telnet/SSH, or by button press on encoder (available only on OMNI-112). Using this method ignores any standby projector cooldown or timeout settings of decoder.

Option 1: Defining commands on Decoder (Preferred method)

  1. Navigate to web interface Serial tab of decoder.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port, set mode to output and Input as Not used:

mceclip5.png

  1. Define the display command, in ASCII or HEX, and Mode to raw. Available display command sets are:
    1. Display On | Display Off
    2. Volume Up | Volume Down
  2. Telnet/SSH to decoder and trigger display control using following command,

TrigRS232X Y: Trigger the RS232 command Y (on, off, vol+ or vol-) on RS232 port X (1 or 2)

Option 2: Defining commands on Encoder

  1. Navigate to web interface Serial tab of encoder.
  2. Define the display command, in ASCII or HEX, and Interpret on to encoder. Available display command sets are:
    1. Display On | Display Off
    2. Volume Up | Volume Down

NOTE: Setting “Interpret on” to encoder implies that commands are defined/stored on encoder. If set to decoder, commands are to be defined on the decoder.

 

  1. Navigate to web interface Session tab.
  2. Under AUX control and set source to Commands.
  3. Define the Destination IP address and UDP port of the decoder:mceclip6.png
  1. Navigate to web interface IP INPUT tab of decoder.
  2. Enable an INPUT, e.g. INPUT 5, with no Multicast address defined, and Port set to that in step 5:

mceclip7.png

  1. Navigate to web interface Serial tab.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port and set mode to output:

mceclip8.png

  1. Telnet/SSH to encoder and trigger display control using following commands. If using OMNI-112, front panel buttons can also be used.
    1. InputBtn Y: Select an input (1, 2, or tog)
    2. DisplayBtnX Y: Send the command Y (on, off, toggle) for HDMI input X (1 or 2)
    3. VolumeBtn X: Send the volume up or down command

 

CEC

Display control using CEC is a decoder native feature. To enable this feature,

  1. Navigate to web interface HDMI Output tab of decoder.
  2. Configure Timeout (seconds) between 30 – 900 (inclusive).
  3. (Optional) Configure Projector cooldown (seconds) between 5 – 300 (inclusive):

mceclip9.png

 

Terminology:

  • Auto on: When source IP stream detected, turn display on using CEC
  • Projector cooldown: Minimum wait time in seconds before CEC display on allowed, after a CEC display off.
  • Timeout: Time in seconds before CEC display off sent after loss of IP stream detected.
  • Type:
    • DispSW AVon: Hold output high, aka black frame. Turn on/off display using CEC based on source IP stream presence.
    • DispSW AVSW: Drop output signal if no active source. Turn on/off display using CEC based on source IP stream presence.
    • AV SW: Do not turn on/off display using CEC. Drop output signal if no active source.
    • Always On: No function. No CEC control. Hold output high, aka black frame.

 

 

 

Controlling upstream devices (source) from downstream (TV)

 

RS-232

Serial interface provides RS-232 control of both downstream (TV) and upstream (source). Source control is provided through enabling bidirectional.

  1. Navigate to web interface Serial tab of decoder.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial Configuration, set Bidirectional parameters to that of the encoder, or IP controllable source. Following image depicts decoder @ 10.10.8.14, speaking to encoder @ 10.10.8.35 listening on UDP port 1204:

  1. Navigate to web interface Serial tab of encoder.
  2. Set either serial_port1 or serial_port2 to serial mode, under Serial port configuration.
  3. Under Serial configuration, select desired port and set mode to Not used:

  1. Navigate to web interface Session tab.
  2. Under AUX section, enable Bidirectional function, and set Listen port (must match decoder parameter):

IR

Control of headend (source) from downstream using IR, mirrors RS-232 setup. The only difference is that the serial_port# used needs to be configured for infrared, under Serial tab of web interface:
