Programming the Unit

The AMCM unit comes factory set to operate in the Standard CATV mode. The unit has 4 valid operating modes: STD CATV, 

IRC, HRC & broadcast UHF/VHF. (Skip to the next section for programming the operating mode)

Programming a Channel

1.   Navigate to the desired channel number by depressing the 

p

 UP and 

q

 DN buttons.

 

a.  Continuous past 99 for channels 100-135, the +100 red LED will illuminate.

2.   Press

 ENTER

 when you reach the desired channel setting. This will tune the modulator output to the corresponding 

channel frequency for this entry.

 

 a.   The LED display will blink continuously during the channel programming process and will not change the output 

frequency the unit is programmed until

 ENTER

 is depressed.

 

 b.   The unit has a special feature that alerts an operator of an inadvertent or desired change to the channel display by 

flashing the LED readout. The LED display will continue to flash for 30 seconds if

 ENTER

 is not depressed and then 

will return to the display of the previously programming channel entry setting.

It is strongly recommended to use the Blonder Tongue MIPS-12C or the MIRC-4D 

power supplies with the AMCM-860. It is also recommended to use the optional 

headend fan unit (QTHF, Stock No. 6235) when deploying more than 6 AMCM-

860 units in the MIRC-12V chassis. A rack space above and below the chassis unit 

is suggested for heat dissipation and air flow.
