6.8 "Main > EAS" Screen
The “Main > EAS” screen (Figure 6.8, next page) is an EAS feature enabling all input program streams to be replaced by the
input present on the ASI or IP input. This web page allows the user select between ASI and IP. For IP, the user also enters
the address, port and protocol. Commands are available for manual test of the EAS mode. This tab is only displayed when
the output mode (see Section 6.6) is active.
The TS requirements for the EAS input are as follows:
(1) The ASI input should be a single program input with (PMT[O]). If multiple programs are present in the EAS TS
input,then program #1 (PMT(O) or first PMT) will be selected for EAS override. The other programs will be ignored.
(2) If ASI input #1 thru #11 have multiple audios, then only the first Audio service is overridden with EAS Audio.
The front panel ASI Input LEDs will be flashing green when EAS is activated.
Upon removing the trigger mechanism the unit will return to its normal operation.
When EAS source = IP
