    System User Guide Installation The Pyxis range of routers is supplied in 1U and 3U frames. The 3U has an integral power supply whilst the 1U has an external power supply. All cards and modules are accessible from the front once the door has been opened or removed. All signal and control cables are connected to the rear panels.

    Screws Figure 5: Card Retainer (3U) The Pyxis 3U frame is shipped with a card retaining bracket and card retaining strip fitted. These hold the modules, PSUs and Controllers firmly in place during transit. The card retaining bracket and card retaining strip must be removed before power is connected to the router.

  • Page 19: Control Options

    System User Guide Control Options A Pyxis router supports a variety of Snell control systems; Nebula, Aurora and Workbench. Nebula and Aurora combine to make up the legacy control system and Workbench the next generation with enhanced features and user front end. The control system defines which control card must be used within the Pyxis frame.

  • Page 20: 2449: Nebula Controller

    2449: Nebula Controller The Pyxis router is supplied with a basic database and default settings for all control ports. This means external controllers, control panels and Under Monitor Displays can be directly connected to the frame if required. The database contains system configuration details such as the number of logical/control levels within the system, signal types and control panel functions.

  • Page 21: The System Database

    Only version 3 (or higher) software will function with Pyxis. The simplest way of checking the version installed on a PC is to run the editor and click on the Snell icon or select 'ABOUT' under the configuration dropdown, it should show Nebula Editor Version 3.2.0.88 or newer.

    It uses numbers in the range 0 to 1023 to set, acknowledge and poll crosspoints via a single router control module. Pyxis ports must be configured for this protocol if the router is to be controlled by an Aurora control system Although labeled ‘RS485’, this port is actually software configured to be point to point, as with RS422,...

    SW2 P clock select is used to select between 10 MHz and 20MHz µP clock frequency and should be left set to 10MHz. SW3 System Run Mode determines which mode of operation the Pyxis powers up in (i.e. NORMAL or TEST). NORMAL is the standard mode of operation. TEST selects a special test mode where various features of the Nebula Controller hardware can be tested by Snell.

  • Page 25: Figure 16: 2449 Base Card - Switch Locations

    PYXIS System User Guide SW8 Control mode selects which protocol the serial control ports will use. ‘GENERAL’ configures both RS485 ports to support General Switcher protocol. ‘PANELS’ configures both RS485 Remote ports to support Multi-drop Comms protocol. See the next section for a description of these protocols.

    Software is also required to enable Ethernet Control, detailed in section 5.2.3 A standard CAT5 patch cord may be used to connect the Pyxis active Ethernet port to a 10 Base-T hub or switch. By default, the SC13 chip is configured for DHCP, meaning that a DHCP Server must be present on the same network segment in order for an IP address to be assigned.

    5.1.7 Video Reference (REF1, REF2, REF3) The 3U Pyxis provides connections for three loop-through video reference inputs. The Pyxis uses the reference (when allocated correctly to a source) to switch between sources in accordance with SMPTE RP168. If no references are present the Pyxis will ‘crash’ switch sources.

  • Page 49: Audio

    System User Guide Audio Pyxis has been designed to seamlessly handle, Analogue, AES, and MADI audio signals. A comprehensive range of modules and rear panels are available to support most applications. Each module has a ‘level’ set and a ‘Dest Offset’ switch; these allow modules to be configured as individual Levels or as part of one larger Level.

  • Page 50: Madi

    MADI is currently documented in AES10-2003. The MADI standard includes a bit-level description and has features in common with the two-channel format of AES3. Pyxis supports either 56 channels (28 stereo pairs) or 64 channels (32 stereo pairs) but not both simultaneously, with sampling rates of up to 48 kHz and resolution of up to 24 bits per channel.
  • Page 51 PYXIS System User Guide = Router mode, ON = Transcoder mode (up) (down) Router Mode allows the user to route any input (MADI, AES or Analogue) to any output (MADI, AES or Analogue).

    7.1.2 Rear Panel Port Mapping for Digital Video Pyxis is designed to be versatile allowing different module combinations to exist in the same 3U frame. In normal practice rear panels are matched with their corresponding modules e.g. a 9100 (72x72 SDI Rear Panel) connected to a 9203 (72 x 72 Non-Reclocking Digital Video Module).

    PYXIS System User Guide It is possible to fit other combinations of rear panel and modules, and these will work perfectly well, but the mapping will be different. If a larger capacity rear panel is used with a smaller capacity module then there is no longer a one to one mapping and route numbers will no longer match the BNC connector numbers on the rear panel.
