M EQ1000A - This illustration shows the rear of the MEQ1000A.
The ASI c onnectors are type BNC f em al e.
The ASI input is us ed to input SCTE-18 data in ASI f ormat f or
use with DTAs and in EAS dais y-chaining applic ati ons.
R1; RF OUT PUT – This is the high level (61 dBmV), 54 to 1002 MHz, output from the
MEQ1000A upc onverter s ection.
R2; Contact Closure Termi nal - Connect thes e to EAS Rec eiver Contact Cl osur e
cables to allow the triggering of EAS activati on.
R3; ASI Input - This is f or receiving EAS and DTA data f rom a Drake EH24, EH24 A,
