Multicast Mode:
Verify that dipswitch SW16-8 is OFF. Connect the output of your AES enabled
EAS unit to AES input eight. Connect the sustained relay contacts of your EAS unit
between ground and remote control input 16 on the DAS 8.4 Plus. When the EAS
unit trips, the DAS 8.4 PLUS will switch AES input eight to all four AES outputs.
The four led’s associated with input eight will start to flash in sequence. When the
alert/test is completed, the relay contact of the EAS unit should open and the DAS
8.4 Plus will return to its previous I/O configuration. NOTE: You may also put the
DAS 8.4 Plus into Multicast mode via serial commands listed on page 16.
Note: To convert your EAS unit from analog audio to AES digital audio, check out
either of the Broadcast Tools Analog to Digital converters: ADCS-III or ADC-1
Mounting:
The DAS 8.4 Plus is designed to be rack mounted in a standard 19” rack, (1-RU).
It should be mounted in an area that is accessible from the rear and preferably away
from sources of heat. We recommend before permanently installing the DAS 8.4
Plus that you bench test and become familiar with the operation of the unit.
