IR TV Controller
 
RF Tuner 
    Frequency Range:   NTSC television 55.25 to 801.25 MHz, 62.5KHZ fine tune resolution 
  Maximum Input:  
+20dBmV 
    Video Gain: 
±5% maximum, 2% typical

±3 degrees maximum, 2 degrees typical 
 
iCC-Net (ICC2-IRC) 
    Operation: 
Carried over the same RF coax connection as TV channels 
 
    Data Receive: 
Mid-band VHF, 74.7MHz, sent from IC Head-End Network Controller 
 
     
-25 to +35 dBmV signal level 
  Data Transmit: 
Sub-band, 5.6MHz sent to Head-End Network Controller 
     
±
 
80 KHz max carrier deviation 
   
+49dBmV nominal 
 
iCW-Net (ICW-IRC) 
  Connector 
RJ-45 female 8 pin Telco jack 
     
RS-485 type data requiring at least 2 twisted wire pairs with shield or fifth conductor 
  Recommended Wire:   CAT3/CAT5 compatible unshielded, max 3300 feet [914m] from iC Head End 
 
CC-HSD Scan Sensor  
  Range: 
Senses presence of TV scanning, from 15-35 KHz, magnetic pick-up 
  Includes: 
3.5mm plug, 4ft. cable, stick-on TV sensor 
 
Status Indication 
The Net and Power LEDs have special modes that help system setup and troubleshooting. 
 
  Power LED   
Uses a blink mode when the IRC logic and Sensor feedback do not agree 
 
 
     
 
 
 
 
 
     
 For example, if the TV Controller knows the TV should be on, but the sensor 
input does not see scanning activity, the Power LED blinks rapidly. 
 
  Net LED 
 
Blinks when it is receiving network data 
 
LED Response 
Off – DC power to IRC missing or other internal power problem 
Solid On – no network communication 
Blinks once per second - communicating over network 
 
     
The Head-End Network Controller sends out a “heartbeat” command once every 
second that will flash the Net LED.
