[EAS] EAS Status Lights on AOIP Mixing Boards with GPIO

[Rod Simon]

My first thought is running EAS alerts through a channel on a board legal? Or at the least best practice?

My experience is with a much larger installation with 5 PowerStations, 5 QOR, and 1 studio Engine. We also have a DASDEC EAS Encoder / Decoder.

The Air Chain to the transmitter uses an Axia AES node to feed the DASDEC, the output from the DASDEC goes back in the AES node using livewire to feed the multiple paths to the transmitter, streaming computer, and monitor points.

To address your question The QOR is much less configurable than the PowerStation with an element or fusion control surface. We have a GPIO triggered by the framed contact on an ISDN unit that only lights the channel light when the ISDN is connected.  Pathfinder can also control many aspects of the element.

Check with Telos, I do know Telos is slowly adding SNMP to their products (at least the x-nodes) so it may be possible with the latest QOR firmware.

I have been testing open source EAS player code with a dev unit from AXIA, a DESQ and Qor16.  We can send out a Livewire RTP stream to the board where it shows as a channel with levels.  Qor sends out an RTP stream to our player with a mix of mics/inputs and playout audio from the machine to an icecast mount point that is picked up by the Barix at radio transmitter site.

For new user or retrofit of station with separate automation, they can configure EAS alert player to create a Alert and have the qor recognize our output from DB9 to the qor GPIO plug. When immediate BI alert plays, a relay is triggered then the channel overrides in the QOR, plays the alert until the relay is reset and then resumes from normal source.   We have the capability to create an on demand RTP stream when an alert is issued for the Qor as a multicast address to detect and overide an incoming channel.

The question I have, is there anyone that has knowledge of scripting, standards or experience with flashing board and tally lights on newer digital consoles while EAS\CAP event are in progress that can be controlled with GPIO?
