Regulatory and Safety Notices FCC Notice Part 15 of the Federal Communication Commission Rules and Regulations has established Radio Frequency (RF) emission limits to provide an interference free radio frequency spectrum. Many electronic devices produce RF energy incidental to their intended purpose. These rules place electronic equipment into two classes, A and B, depending on the intended use. Class A devices are those that may be expected to be installed in a business or commercial environment.
Modifications The FCC requires the user to be notified that any changes or modifications made to Avid hardware that are not expressly approved by Avid Technology may void the user’s authority to operate the equipment. Cables Connections to Avid hardware must be made with shielded cables with metallic RFI/EMI connector hoods in order to maintain compliance with FCC Rules and Regulations. PRODUCTS WITH MULTIPLE POWER INPUTS: WARNING: Each power input is intended to be connected to a separate branch circuit.

Euphonix CO-600 Change-Over System For New Core DF66 Redundancy Authorized Service Personnel ONLY: Important Note! Due to the “Hot Swap” capabilities of all card components in the COS chassis, power can be applied to the unit at any time before after or during card installation. It is recommended, however, that this feature only be used when necessary. This is because the hot swap system can not protect from all possible errors made by the operator during card installation.
Euphonix CO-600 Change-Over System For New Core DF66 Redundancy Overview The change over redundancy system allows running a backup DF-66 SuperCore in parallel with the primary unit. The change over switch distributes all audio signals to both the primary and backup DSP cores. If the diagnostics system detects a fault, or even a potential primary DF-66 failure, the entire output audio path (including all I/O devices) is switched over to the backup system.
Euphonix CO-600 Change-Over System For New Core DF66 Redundancy The CO-600 has two primary functions: 1) a MADI splitter that provides 2 MADI outputs for each MADI input and 2) a MADI switchover that switches each MADI output between Primary and Backup MADI sources. Figure 1 provides a conceptual block diagram of signal flow and behavior. External MADI inputs are distributed to both the Primary Core and the Secondary Core so that the sources are always available to both cores.
Euphonix CO-600 Change-Over System For New Core DF66 Redundancy Figure 2 Single CO-600 Chassis Management Provision for the optional CM604/CM606 is be provided. The CM604 queries information such as field replaceable unit status, presence, and performs health monitoring of system components. It also controls, when present, the power-up sequencing of each component and the power-on/off to each slot.
Euphonix CO-600 Change-Over System For New Core DF66 Redundancy Figure 3 Front and Rear Panels Front Panel The front of the unit consists of eight card slots in a 2U chassis. The four full-length slots on the left side can be filled with change over cards. The four half-length slots on the right side are used for two hot swappable power supply modules, a frame controller card and a SNMP chassis management card.
Euphonix CO-600 Change-Over System For New Core DF66 Redundancy The frame controller connections consist of an Ethernet port, serial port and GPIO. They can also be set to a “dead man’s switch” mode where an interruption in the input logic signal would toggle the change over switch to the other output. An additional Ethernet connection and serial port in the upper slot are for a separate chassis management card (SNMP) described below.
Authorized Service Personnel ONLY: Detailed Description and Service Info The Change-Over System (COS) Chassis is designed to provide automated or manual switching between redundant MADI streams in a critical production environment. It does this by grouping redundant MADI media in sets of 4 MADI ins and 4 MADI outs to be switched as a whole, then allowing up to four groups be switched by a single chassis. Multiple Chassis can be daisy chained for larger scale systems.
Authorized Service Personnel ONLY: Switch Cards Zero to four Switch Cards(CO 601) can be installed in a chassis. Switch cards can be installed in any order or in any available positions. However, it is generally easier to operate the COS if they are installed without gaps from the bottom to the top. Install a Switch Front Card in an available front slot on the left side of the chassis. Make sure the ejector clips are completely latched. Use the same care as when inserting the Controller Front Card.
Authorized Service Personnel ONLY: Power Supplies Power the COS unit up by plugging it into a power source. There is no power switch. On the Power Supply Cards, check that the green “Power Good” LED is lit and the Red “Halt” LED is not lit. If this is not the case, replace the power supply. Hot Swap LEDs On the Controller Front Card and any Switch Front Cards installed, there are three hotswap control LEDs. These consist of a green “OK” LED, a yellow “Fault” LED and a blue “OOS” (out-of-service) LED.
Authorized Service Personnel ONLY: intentionally disabled the card. No other LEDs should be on when the “OOS” LED is lit. The operator can only disable the Controller Card by partially ejecting the Controller front or rear card. However, the Switch Cards can also be disabled and re-enabled via the Ethernet and serial interfaces. If a switch card has been disabled via software, it can be re-enabled via Ethernet or serial control. Or, it can be re-enabled by toggling the ejector latch.
Authorized Service Personnel ONLY: Front Panel Switch Each Switch Front Card has a 3-position toggle switch, which allows for forcing either DSP Bank connector to be connected to the I/O connector. It also has a center “Auto” position which automatically sets the Bank A or Bank B connection based on conditions. This toggle switch will only function when the “OK” LED is lit and the board is operating normally.
Authorized Service Personnel ONLY: Global Back Plane Switch NOTE: Not used when connected to Emix or MaxAir. The global back plane switch is asserted when an operator defined GPIO input pin is grounded. The operator can configure the switch to assert by a specific GPIO pin being grounded, by any GPIO pin being grounded, or never by a GPIO pin. The pin selection is configured via Ethernet or serial control using FrameMon Software (available from Euphonix).
Authorized Service Personnel ONLY: The GPIO output pins will not function (logic high) when the Controller Card is “out-ofservice”. The GPIO output pin states are not dependent on which or any Switch Cards being installed. Daisy-Chaining Chassis’s via GPIO NOTE: Not used when connected to Emix or MaxAir. Multiple COS Chassis’s can be daisy-chained together for larger scale integration.
Authorized Service Personnel ONLY: Completely remove the card being careful not to touch any electronics on the card or neighboring cards in the process. Once the card is completely removed, and anti-static handling precautions are observed, any changes requiring handling of the cards can be made. To re-insert the card, align the Card PCB up with matching groves in the slot hardware.
Authorized Service Personnel ONLY: Ethernet connection The COS supports DHCP or static addressing and will hold its IP address through power cycles. IP address, network sub net mask, and gateway address can be configured through the serial or Ethernet interfaces.
Authorized Service Personnel ONLY: RS-232 Control RS-232 control can be performed using a standard terminal emulation software application on a PC such as HyperTerminal. The baud rate is 115200, 8 data bits, 1 stop bit, no parity. The RS-232 port can be connected to a PC serial port using a standard DB-9 Male-Female “straight through” cable. After booting, the Controller Card will output the version number in a carriage return delimited string.

Euphonix CO-600 Change-Over System For New Core DF66 Redundancy Latency The introduction of delay in the MADI signal path can have a detrimental effect on the performance of the system. Latency has been kept to a minimum - less than 500 nanoseconds. Hot Swap All cards are capable of Hot-Swapping without interfering with the operation of the other cards and components in the system. Power The power specifications for the PS-607 are listed below: 1.
