Contemporary Research ICC2-IRC - Manual (Page 5)

Contemporary Research Corporation 5 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
Video Phase: ±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.
Logic Sensor LED Response
ON ON Solid On
ON OFF Blinks – states do not agree
OFF OFF Solid Off
OFF ON Blinks – states do not agree
