SquawkBox User Manual 1 – Overview The SquawkBox CobraNet Audio Interface is a cost-effective desktop audio product designed to allow a user to easily monitor multiple channels of audio on a CobraNet-based AV system. Up to 16 channels can be monitored using either the internal speaker or headphones. A 17th “override” channel can be initiated externally for system wide announcements.
SquawkBox User Manual 2 – Installation Figure 1 – SquawkBox Connectors and Indicators 1 Power Socket – Use with optional 12 V DC wall wart only. 2 CobraNet Ethernet interface connector and indicators 3 3.5mm Headphone jack Installation of the SquawkBox only requires that power be supplied to the unit and a connection made to the CobraNet network. If the SquawkBox is to be powered using PoE, then simply o Attach the CobraNet I/F port to a spare PoE-enabled port on a PoE switch using a CAT-5 cable.
SquawkBox User Manual 3 – User Operation Figure 2 - User Controls The main feature of the SquawkBox is to monitor up to 16 different audio streams on a CobraNet network. Each stream is identified by selecting a bundle and submap combination that tells the SquawkBox where to locate a given stream. The audio stream can also be given a descriptive name to help identify what audio is being monitoring. This descriptive name is shown on the screen whenever that audio stream is selected.
SquawkBox User Manual 3.2 – Channel Controls Figure 3 - SquawkBox Configuration Screen Each of the 16 possible audio streams has its own Name, Bundle and Submap. Each stream can be from a different Bundle/submap combination and combinations may be duplicated if required. Name Each audio stream that can be monitored can be given a descriptive name. The name can be up to 16 characters long and include upper or lower case letters, numbers or punctuation marks.
SquawkBox User Manual 3.4 – Load/Save Settings In order to ease configuration of multiple SquawkBox devices, the settings may be saved and that saved configuration then loaded into other SquawkBox devices. Once all the parameters have been set correctly, the complete configuration can be saved by clicking the Save button at the top of the form (as shown in Figure 4). The Configuration Save dialog will appear allowing you to select a folder and a file name.
SquawkBox User Manual 4 – Remote Control *Note: This feature is only available in firmware version 4.0 or later. The firmware version number is displayed when the SquawkBox powers up. .Devices can be updated in the field. Contact Attero Tech technical support for more details. The SquawkBox has a remote control feature that allows a 3rd party control system to control certain aspects of the SquawkBox functionality remotely.
SquawkBox User Manual When a change to remoteVolume is made, the name for the newly selected channel is displayed on the screen of the SquawkBox, Attero Tech LLC 2014 Page 7 614-00007-04
SquawkBox User Manual 5 – Remote Override The SquawkBox includes an override facility whereby the audio stream being monitored can be temporarily overridden and switched remotely to an override audio stream. This allows the SquawkBox network to be used for pages or system broadcasts and so on.
SquawkBox User Manual 5.2 – Override Test Figure 6 - Override Test Form The override test form allows the user to test the override settings on a SquawkBox system. It can be used to generate full system or partial system overrides as required. Select the EMERGENCY option for a full system override or select the blank option for a partial system override. If a partial system override is required, one or more of the Group check boxes will also need to be checked.
SquawkBox User Manual To override one or more groups of units, use a general override but broadcast to all units using an appropriate broadcast destination IP address. This is achieved by leaving the Tag field empty (just send NULL’s) and including a group mask. The group mask must contain at least one active group for the override to activate.
SquawkBox User Manual For dynamic assignment, a DHCP server that supports BOOTP is preferable. Control Center can be used as a temporary solution but Control Center, on its own does not provide any facility to update the SquawkBox firmware (a BOOTP server is required to do that). While a BOOTP server provides a subnet mask that’s configurable on the server, Control Center cannot.
SquawkBox User Manual 6 – Troubleshooting 6.1 – Checking the Network Connection The CobraNet network connection can be diagnosed by noting the status of the LEDs just above the Ethernet connector on the SquawkBox. These LEDs will be on, off, or flashing depending on the current state of the network connection. Below is a table showing the states of the LEDs and what device status they represent.
SquawkBox User Manual 7 – ARCHITECTS & ENGINEERS SPECIFICATION The CobraNet interface unit shall provide monitoring of any one of 16 CobraNet audio channels, with user selection of the monitored channel facilitated by “Channel Up” and “Channel Down” keypad buttons. Monitoring will be through either an internal loudspeaker or via a 3.5mm headphone jack. The internal speaker shall be automatically muted when a headphone plug is inserted into the 3.5mm jack.
SquawkBox User Manual APPENDIX A – Introduction to CobraNet CobraNet is an audio networking technology for delivery and distribution of real-time, high quality, uncompressed digital audio using a standard Ethernet network. It is implemented using a combination of hardware, firmware, and the CobraNet protocol. Unlike other audio networking or distribution technologies, CobraNet is a true network and exists on standard Ethernet networks using standard Ethernet hardware.
SquawkBox User Manual The modes are as follows: o Unicast – Used for one-to-one connections. In this mode, only one receiver at a time can receive this bundle. Once a link is established from this transmitted bundle to a receiver, any future requests for that bundle from other potential receivers will fail. o Multicast – Used for one-to-many connections. This mode broadcasts its contents over the entire network. There is no restriction on the number of receivers.
