DMX-512 Snapshot Procedure

The i series e Control Module has the ability to store scenes in the rack itself. The scenes are saved from a snapshot picture taken of the levels coming in on the DMX-512 control line. When the record sequence is triggered, the Scene is copied from the DMX-512 input and stored in the EEPROM on the backplane of the control module. This means that scenes always remain with the rack, even if you swap control modules. The three different types of scenes pile-onto each other with the DMX-512 input in a Highest Takes Precedence [HTP] fashion.  The Panic and Analog Scenes are described in this section. For recording and playing the 100 backup scenes, refer to the Remote Hand-Held web page http://www.iseriese.com/handheldremote.htm

--------------------------------------------------------------

The Panic Scene -

The procedure to record and activate the panic scene is to connect a Rememberance Panic Station (CTP-8-1022) or Remembrance Entry Station (CTP-8-1021) to the panic circuitry on the i series e control module backplane. Connect as described below. These signals should be Daisy-chained between racks.

 

  1. [ COM of Remembrance station ] connects to [ GND of TB1 on i series e Backplane ]
  2. [ V+ of Remembrance station ] connects to [ +12VUR of TB1 on i series e Backplane ]
  3. [ T/C of Remembrance station ] connects to [ T/C of TB2 on i series e Backplane ]
  4. [ VOUT of Remembrance station]   connects to [ PANICB MAINT] of TB1 on i series e Backplane ]

 

DMX-512 Snapshot Record Mode for the Panic input:

  1. Activate the scene to be recorded on the DMX-512 input port.
  2. De-activate the Analog Inputs and any Backup Scenes to make sure the scene is   correct.
  3. Push and hold the Panic or ON/OFF button in the on position [ the led will light] for  about 2 minutes.
  4. When the control module enters the snapshot mode, the lights will dim proportionally by 50%, and the Diagnostics LED on the control module will light.
  5. Continue holding the Panic or ON/OFF button until the lights return to their original intensity.
  6. Wait 10 more seconds for all control modules to exit record mode.
  7. Release the button.
  8. Test the record sequence by placing a blackout scene on the DMX-512 input port. Press the Panic or ON/OFF button. The scene will activate.
  9. To disable the scene from being re-recorded accidentally, disconnect the T/C termination between the Entry or Panic station(s) and the dimmer rack(s). The wire can be moved from T/C to the blank termination next to T/C.
  10. .When the panic scene is active, the PANIC LED on the control module will light up.

When  the Panic Scene is active, the PANIC LED on the control module will light up.

The 12 Analog Scenes -

The procedure to record and activate one or more of the analog scenes is to connect a Rememberance   Analog Station (CTP-8-1001 through CTP-8-1012) to the input circuitry on the i series e control module backplane. Connect as described below. These signals should be Daisy-chained between racks.

  1. [ COM of Remembrance station ] connects to [ COM of TB4 on i series e Backplane ]
  2. [ V+ of Remembrance station ] connects to [ +V of TB4 on i series e Backplane ]
  3. [ T/C of Remembrance station ] connects to [ T/C of TB2 on i series e Backplane ]
  4. [ A1 through A12 of Remembrance station ] connects to [ A1 through A12 of TB4 ] on i series e Backplane

 

DMX-512 Snapshot Record Mode:

  1. Activate the scene to be recorded on the DMX-512 input port. (usually from the control console).
  2. De-activate the Panic Input and any Backup Scenes to make sure the scene is right.
  3. If you desire a programmable fade time to be associated to the analog input, then patch DMX-512 dimmer channels 511 & 512 to the same control channel source (like the last channel on your console), and set the fade time according to table below. A 10% level difference between DMX-512 channels 511 and 512 will cause the control module to treat the 2 levels as lighting levels as opposed to fade times. Each analog input scene has its own fade time associated with it. Fade times operate as a damping factor for analog pot station inputs, but operate as a fade time when connected to the VOUT of an entry station.

Approximate Fade Times

Full = 100 seconds

98% = 30 seconds

95%= 30 seconds

93% = 20 seconds

90 %= 9 seconds

80 %= 8 seconds

70% = 7 seconds

60% = 6 seconds

50% = 5 seconds

40% = 4 seconds

30% = 3 seconds

20% = 2 seconds

10% =1 second

0% = instantaneous

  1. Go to the Analog Station. Slide all the channel faders to off.  Slide the master fader to full. Push and hold the ON/OFF button in the on position with the led will lit, for about 5 seconds.
  2. When the control module enters DMX snapshot mode, the lights will dim proportionally by 50%, and the Diagnostics LED on the control module will light.
  3. Slide up the channel fader that is to save the current live scene.
  4. Continue holding the ON/OFF button while the lights return to their original intensity.
  5. Wait 2 more seconds for all control modules to exit record mode.
  6. Release the ON/OFF button.
  7. Test the record sequence by placing a blackout scene on the DMX-512 input port. Fade up the newly recorded scene on the channel fader (the ON/OFF LED should be lit and the Master fader set at full). The scene will activate.
  8. To disable the scene from being re-recorded accidentally, disconnect the T/C termination between the analog station(s) and the dimmer rack(s). The wire can be moved from T/C to the blank termination next to T/C. It's a good idea to put a T/C label on the wire.

When any analog input is active [ above 6% ], the ANALOG LED on the control module will light up.
