MEQ1000A -

 This illustration shows the rear of the MEQ1000A.

The ASI connectors are type BNC female.

The ASI input is used to input SCTE-18 data in ASI format for

use with DTAs and in EAS daisy-chaining applications.

R1; RF OUTPUT – 

This is the high level (61 dBmV), 54 to 1002 MHz, output from the

MEQ1000A upconverter section.

R2; Contact Closure Terminal - 

Connect these to EAS Receiver Contact Closure

cables to allow the triggering of EAS activation.

R3; ASI Input -

EH244, EH244-IP or MEQ1000A.

 This is for receiving EAS and DTA data from a Drake EH24, EH24A,

R4; Input Module Slot A.
R5; Input Module Slot B.

R6; ASI Output -

 This output delivers the same multi-program transport stream in ASI as

is sent to the QAM modulator.  When the DTA/EAS mode is Enabled, this ASI output no

longer outputs the same data as the QAM output; it now acts as an ASI Loop, outputting

DTA/EAS data only.

R7; RS232 in -

 Connection to a PC or modem for use with remote control / monitoring

program or for firmware update download.

R8; RS232 OUT -

 Loop/Daisychain to another MEQ1000A.

R9; AC Line Cord – 

For connection to the nominal 120 VAC power source. This unit is

designed for use in countries with 120 VAC power standards but the power supply will

accept an input voltage range of 90 VAC minimum to 260 VAC maximum with a power

line frequency of either 50 or 60 Hz.
