7. Under the Alert Origination Action Table ensure that SAGE_GENCG is available as a Serial
Protocol.
8.3.6. Connecting the Audio
The emergency audio from the Sage or TFT decoders must be converted to an AES audio stream before
it can be used with the EMC. You can use the Evertz 7720ADC-A4 Analogue Audio to AES Converter
module, or other suitable device to do this. Connect the AES1 output from the 7720ADC-A4 into the
MADI IN1, 2, 3, or 4 audio inputs on the EMC.
8.3.7. Connecting the GPI Tally Control
The EAS decoders give out a tally control to indicate when an EAS alert message is being broadcast.
This tally output must be connected to one of the GPI inputs on the EMC to signal it to ‘duck insert’ the
emergency audio into the program audio. For the sake of simplicity in this description connect the tally
output from the decoder to the GPI 1 input on the EMC. The corresponding GPI should be configured for
either “Voice over 1 On-Air” or “Voice over 2 On-Air” depending on which MADI input is used. Ensure
that the required Voiceover is configured to use AES as the Format.
8.4. TESTING THE SYSTEM

Please ensure all output video from the EMC is out of your on-air broadcast path
for this test.
8.4.1. Testing the Sage Decoder
On the Sage decoder:
1) Press Week
2) Enter Password
3) Press Enter
The video monitor should now show a scrolling EAS weekly test message. If you do not see the test
message, double check your video connections and ensure that you have the correct video standard
selected in the EMC. Double check that you have configured the correct Sage port and the correct
Device Type for the correct port and that the serial cable is valid and connected to the correct ports.
Check the Evertz Web site at www.evertz.com
for any new firmware releases for the EMC. Check that
you are running the most up to date firmware in your Sage decoder at www.broadcast.harris.com
.
Evertz tested this configuration with the Sage decoder model 1822 with firmware version 5.111
8.4.2. Testing the TFT Decoder
On the TFT decoder:
1) Press Weekly Test button
